Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements (“condensed consolidated financial statements”) have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial information. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K, filed with the SEC on February 25, 2022. There have been no changes to the Company’s significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2021 that have had a material impact on the Company’s condensed consolidated financial statements and related notes. The results for the interim periods are not necessarily indicative of results for the full year. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods. Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and variable interest entities (“VIE”) in which the Company is the primary beneficiary in accordance with consolidation accounting guidance. All intercompany transactions have been eliminated in consolidation. The Company determines, at the inception of each arrangement, whether an entity in which it has made an investment or in which it has other variable interest in is considered a VIE. The Company consolidates a VIE when it is deemed to be the primary beneficiary. The primary beneficiary of a VIE is the party that meets both of the following criteria: (i) has the power to direct the activities that most significantly affect the economic performance of the VIE; and (ii) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Periodically, the Company determines whether any changes in its interest or relationship with the entity impact the determination of whether the entity is still a VIE and, if so, whether the Company is the primary beneficiary. If the Company is not deemed to be the primary beneficiary in a VIE, the Company accounts for the investment or other variable interest in a VIE in accordance with applicable U.S. GAAP. As of September 30, 2022, the Company’s consolidated VIEs were not material to the condensed consolidated financial statements. Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. The Company regularly evaluates its estimates, including those related to bad debt reserves, fair value of investments, useful lives of long-lived assets and intangible assets, valuation of goodwill and intangible assets from acquisitions, contingent liabilities, insurance reserves, revenue recognition, valuation of common stock, stock-based compensation, and income and non-income taxes, among others. Actual results could differ materially from these estimates. As the impact of the coronavirus disease (“COVID-19”) pandemic and the challenging macroeconomic conditions, including rising inflation and interest rates, depressed consumer spending, and the strengthening of the U.S. dollar relative to certain foreign currencies, continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require increased judgment. These estimates and assumptions may change in future periods and will be recognized in the consolidated financial statements as new events occur and additional information becomes known. To the extent the Company’s actual results differ materially from those estimates and assumptions, the Company’s future consolidated financial statements could be affected. Recently Adopted Accounting Standards In May 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-04, Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Topic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) , which clarifies existing guidance for freestanding written call options which are equity classified and remain so after they are modified or exchanged in order to reduce diversity in practice. The standard is effective for public entities in fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The Company adopted the standard during the first quarter of 2022, which did not have an impact on the Company's condensed consolidated financial statements. Recently Issued Accounting Standards Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) , which provides optional expedients and exceptions to contract modifications and hedging relationships that reference the London Interbank Offered Rate or another reference rate expected to be discontinued. The standard is effective upon issuance and may be applied at the beginning of the interim period that includes March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, which clarified the scope of Topic 848 to include derivatives that are affected by a change in the interest rate used for margining, discounting, or contract price alignment that do not also reference London Interbank Offered Rate or another reference rate that is expected to be discontinued as a result of the reference rate reform. The standard is effective upon issuance and may be applied retroactively as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively to any new modifications within an interim period including or subsequent to January 7, 2021. The Company is evaluating the impact on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815) , which clarifies the guidance on fair value hedge accounting of interest rate risk for portfolios of financial assets. The standard is effective for public entities in fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted on any date on or after the issuance of ASU 2017-12. The Company is evaluating the impact on the Company’s consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the guidance of equity securities that are subject to a contractual sale restriction as well as includes specific disclosure requirements for such equity securities. The standard is effective for public entities in fiscal years beginning after December 15, 2023, including interim periods within those fiscal years and will be applied prospectively. Early adoption is permitted. The Company is evaluating the impact on the Company’s consolidated financial statements. There are other new accounting pronouncements issued by the FASB that the Company has adopted or will adopt, as applicable, and the Company does not believe any of these accounting pronouncements have had, or will have, a material impact on its consolidated financial statements or disclosures.

The Company amended the anti-dilution feature in the warrant agreements associated with the Second Lien Credit Agreement, as defined in Note 6, Debt , which resulted in a change in classification from liability to equity, on March 30, 2021 (the “Modification Date”). The Company recorded a marked-to-market charge of $292.0 million through the first quarter of 2021, which was recorded in other income (expense), net on the condensed consolidated statements of operations. Subsequent to the Modification Date, the warrants were no longer subject to marked-to-market charges. The balance of $1.3 billion was then reclassified from liability to equity as the amended warrants met the requirements for equity classification. Refer to Note 6, Debt, for additional information. Derivatives Not Designated as Hedging Instruments As of December 31, 2021, the fair value of foreign exchange derivative assets and liabilities totaled $25.9 million and $10.3 million, respectively, with the aggregate notional amount totaling $2.4 billion. As of September 30, 2022, the fair value of foreign exchange derivative assets and liabilities totaled $64.0 million and $10.1 million, respectively, with the aggregate notional amount totaling $2.0 billion. Derivative assets are included in prepaids and other current assets and derivative liabilities are included in accrued expenses and other current liabilities in the condensed consolidated balance sheets. The Company recorded total net realized gains of $26.8 million and $61.3 million for the three months ended September 30, 2021 and 2022, respectively, and $3.2 million and $101.5 million for the nine months ended September 30, 2021 and 2022, respectively, related to foreign exchange derivative assets and liabilities. The Company recorded total net unrealized gains of $3.7 million and $13.1 million for the three months ended September 30, 2021 and 2022, respectively, and $39.1 million and $38.3 million for the nine months ended September 30, 2021 and 2022, respectively, related to foreign exchange derivative assets and liabilities. The realized and unrealized gains and losses on non-designated derivatives are reported in other income (expense), net in the condensed consolidated statements of operations. The cash flows related to derivative instruments not designated as hedging instruments are classified within operating activities in the condensed consolidated statements of cash flows. The Company has master netting arrangements with the respective counterparties to its derivative contracts, which are designed to reduce credit risk by permitting net settlement of transactions with the same counterparty. The Company presents its derivative assets and derivative liabilities at their gross fair values in its condensed consolidated balance sheets. As of December 31, 2021, the potential effect of these rights of set-off associated with the Company’s derivative contracts would be a reduction to both assets and liabilities of $10.3 million, resulting in net derivative assets of $15.6 million. As of September 30, 2022, the potential effect of these rights of set-off associated with the Company’s derivative contracts would be a reduction to both assets and liabilities of $9.7 million, resulting in net derivative assets of $54.3 million and net derivative liabilities of $0.3 million.

Debt Disclosure [Abstract]
Debt	Debt The following table summarizes the Company’s outstanding debt (in thousands): December 31, 2021 September 30, 2022 Balance Effective Interest Rate Balance Effective Interest Rate Convertible senior notes due March 2026 $ 2,000,000 0.2 % $ 2,000,000 0.2 % Less: Unamortized debt discount and debt issuance costs (17,463) (14,341) Total long-term debt $ 1,982,537 $ 1,985,659 Convertible Senior Notes On March 8, 2021, the Company issued $2.0 billion aggregate principal amount of 0% convertible senior notes due 2026 (the "2026 Notes") pursuant to an indenture, dated March 8, 2021 (the "Indenture"), between the Company and U.S. Bank National Association, as trustee. The 2026 Notes were offered and sold in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The 2026 Notes are senior unsecured obligations of the Company and will not bear regular interest. The 2026 Notes mature on March 15, 2026, unless earlier converted, redeemed or repurchased. The proceeds, net of debt issuance costs, were $1,979.2 million. The initial conversion rate for the 2026 Notes is 3.4645 shares of the Company's Class A common stock per $1,000 principal amount of 2026 Notes, which is equivalent to an initial conversion price of approximately $288.64 per share of the Class A common stock. The conversion rate and conversion price are subject to customary adjustments under certain circumstances in accordance with the terms of the Indenture. The 2026 Notes are convertible at the option of the holders before December 15, 2025 only upon the occurrence of certain events, and from and after December 15, 2025, at any time at their election until the close of business on the second scheduled trading day immediately preceding March 15, 2026, only under certain circumstances. Upon conversion, the Company may satisfy its conversion obligation by paying or delivering, as applicable, cash, shares of the Company’s Class A common stock, or a combination of cash and shares of the Company’s Class A common stock, at the Company’s election, based on the applicable conversion rate. In addition, if certain corporate events that constitute a make-whole fundamental change (as defined in the Indenture) occur, then the conversion rate will, in certain circumstances, be increased for a specified period of time. Additionally, in the event of a corporate event constituting a fundamental change (as defined in the Indenture), holders of the 2026 Notes may require the Company to repurchase all or a portion of their 2026 Notes at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid special interest or additional interest, if any, to, but excluding, the date of the fundamental change repurchase. Debt issuance costs related to the 2026 Notes totaled $20.8 million and were composed of commissions payable to the initial purchasers and third-party offering costs. Debt issuance costs are amortized to interest expense using the effective interest method over the contractual term. The Company recorded interest expense of $1.0 million for the three months ended September 30, 2021 and 2022, and $2.3 million and $3.1 million for the nine months ended September 30, 2021 and 2022, respectively, for the 2026 Notes relating to amortization of the debt discount and debt issuance costs. As of September 30, 2022, the if-converted value of the 2026 Notes did not exceed the outstanding principal amount. As of September 30, 2022, the total estimated fair value of the 2026 Notes was $1.7 billion and was determined based on a market approach using actual bids and offers of the 2026 Notes in an over-the-counter market on the last trading day of the period, or Level 2 inputs. Capped Calls On March 3, 2021, in connection with the pricing of the 2026 Notes, the Company entered into privately negotiated capped call transactions (the “Capped Calls”) with certain of the initial purchasers and other financial institutions (the "option counterparties") at a cost of $100.2 million. The Capped Calls cover, subject to customary adjustments, the number of shares of Class A common stock initially underlying the 2026 Notes. By entering into the Capped Calls, the Company expects to reduce the potential dilution to its Class A common stock (or, in the event a conversion of the 2026 Notes is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion of the 2026 Notes its common stock price exceeds the conversion price of the 2026 Notes. The cap price of the Capped Calls will initially be $360.80 per share of Class A common stock, which represents a premium of 100% over the last reported sale price of the Class A common stock of $180.40 per share on March 3, 2021, and is subject to certain customary adjustments under the terms of the Capped Calls. The Capped Calls meet the criteria for classification in equity, are not remeasured each reporting period and are included as a reduction to additional paid-in-capital within stockholders’ equity. Term Loans In April 2020, the Company entered into a $1.0 billion First Lien Credit and Guaranty Agreement (the “First Lien Credit Agreement,” and the loans thereunder, the “First Lien Loan”), resulting in net proceeds of $961.4 million, net of debt discount and debt issuance costs of $38.6 million. The loan was due and payable in April 2025 and could be repaid in whole or in part at the Company’s option, subject to applicable prepayment premiums and make-whole premiums. Beginning in September 2020, the Company was required to repay the First Lien Loan in quarterly installments equal to 0.25% of the $1.0 billion aggregate principal amount of the First Lien Loan, with the remaining principal amount payable on the maturity date. Also in April 2020, the Company entered into a $1.0 billion Second Lien Credit and Guaranty Agreement (the “Second Lien Credit Agreement,” and the loans thereunder, the “Second Lien Loan”), resulting in net proceeds of $967.5 million, net of debt discount and debt issuance costs of $32.5 million. The loan was due and payable in July 2025 and could be repaid in whole or in part, subject to applicable prepayment premiums, make-whole premiums, and the priority of lenders under the First Lien Credit Agreement over any proceeds the Company receives from the sale of collateral. In March 2021, the Company repaid the principal amount outstanding of $1,995.0 million under the First Lien and Second Lien loans, which resulted in a loss of extinguishment of debt of $377.2 million, including early redemption premiums of $212.9 million and a write-off of $164.3 million of unamortized debt discount and debt issuance costs. The loss on extinguishment of debt was included in interest expense in the condensed consolidated statements of operations. Additionally, the Company incurred third-party costs, principally legal and administrative fees, of $0.1 million relating to the extinguishment of the loans. The debt discount and debt issuance costs are amortized to interest expense using the effective interest rate method. For the three months ended March 31, 2021, interest expense of $17.0 million and $24.3 million, respectively, was recorded for the First Lien and Second Lien Loans relating to the contractual interest and amortization of the debt discount and debt issuance costs. The First Lien Loan and the Second Lien Loan were unconditionally guaranteed by certain of the Company’s domestic subsidiaries and were both secured by substantially all the assets of the Company and of these subsidiary guarantors. In connection with the Second Lien Loan, the Company issued warrants to purchase 7,934,794 shares of Class A common stock with an initial exercise price of $28.355 per share, subject to adjustment upon the occurrence of certain specified events, to the Second Lien Loan lenders. The warrants expire on April 17, 2030 and the exercise price can be paid in cash or in net shares at the holder’s option. The fair value of the warrants at issuance was $116.6 million and was recorded as a liability in accrued expenses and other current liabilities on the condensed consolidated balance sheet with a corresponding debt discount recorded against the Second Lien Loan. The warrant liability was remeasured to fair value at each reporting date as long as the warrants remained outstanding and unexercised with changes in fair value recorded in other income (expense), net in the condensed consolidated statements of operations. As of December 31, 2020, the fair value of the warrant totaled $985.2 million. The Company amended the anti-dilution feature in the warrant agreements on March 30, 2021, which resulted in a change in classification from liability to equity. Accordingly, the Company recorded $292.0 million in other income (expense), net during the first quarter of 2021. The liability balance of $1.3 billion was then reclassified to equity as the amended warrants met the requirements for equity classification. 2020 Credit Facility On November 19, 2020, the Company entered into a five-year secured revolving Credit and Guarantee Agreement, which provides for initial commitments by a group of lenders led by Morgan Stanley Senior Funding, Inc. of $500.0 million (“2020 Credit Facility”). The 2020 Credit Facility provides a $200.0 million sub-limit for the issuance of letters of credit. The 2020 Credit Facility has a commitment fee of 0.15% per annum on any undrawn amounts, payable quarterly in arrears. Interest on borrowings is equal to (i) in the case of LIBOR borrowings, 1.5% plus LIBOR, subject to a floor of 0%, or (ii) in the case of base rate borrowings, 0.5% plus the greatest of (a) the federal funds effective rate plus 0.5%, (b) the rate of interest in effect for such day by Morgan Stanley Senior Funding, Inc. as its “prime rate”, and (c) LIBOR for a one-month period plus 1.0%, in each case subject to a floor of 1.0%. Outstanding balances may be repaid prior to maturity without penalty. The 2020 Credit Facility contains customary affirmative and negative covenants, including restrictions on the Company’s and certain of its subsidiaries’ ability to incur debt and liens, undergo fundamental changes, and pay dividends or other distributions, as well as certain financial covenants. The Company was in compliance with all financial covenants as of September 30, 2022. No amounts have been drawn on the 2020 Credit Facility as of December 31, 2021 and September 30, 2022, and outstanding letters of credit totaled $15.9 million and $28.5 million as of December 31, 2021 and September 30, 2022, respectively. Subsequent to September 30, 2022, the Company entered into a five-year unsecured Revolving Credit Agreement which terminated and replaced the 2020 Credit Facility. Refer to Note 13, Subsequent Event, for additional details.

Vesting of this stock is primarily dependent on a service-based vesting condition that generally becomes satisfied over a period of four years. The Company has the right to repurchase or cancel shares for which the vesting condition is not satisfied. The following table summarizes the activity related to the Company’s RSAs (in thousands, except for per share amounts): Number of Weighted-Average Unvested RSAs as of December 31, 2021 632 $ 62.32 Vested (88) 62.37 Unvested RSAs as of September 30, 2022 544 $ 62.32 Employee Stock Purchase Plan (“ESPP”) In December 2020, the Company’s board of directors adopted the ESPP. The maximum number of shares of Class A common stock authorized for sale under the ESPP is equal to the sum of (i) 4,000,000 shares of Class A common stock and (ii) an annual increase on the first day of each year beginning in 2022 and ending in 2030, equal to the lesser of (a) 1% of shares of Class A common stock (on an as converted basis) on the last day immediately preceding year and (b) such number of shares of common stock as determined by the board of directors; provided, however, that no more than 89,785,394 shares may be issued under the ESPP. The Company estimates the fair value of shares to be issued under the ESPP based on a combination of options valued using the Black-Scholes option-pricing model. The Company recorded stock-based compensation expense related to the ESPP of $24.7 million and $9.0 million for the three months ended September 30, 2021 and 2022, respectively, and $89.5 million and $22.9 million for the nine months ended September 30, 2021 and 2022, respectively. During the nine months ended September 30, 2021, 0.5 million shares of common stock were purchased under the ESPP at a weighted-average price of $57.80 per share, resulting in net cash proceeds of $25.5 million. During the nine months ended September 30, 2022, 0.2 million shares of common stock were purchased under the ESPP at a weighted-average price of $103.23 per share, resulting in net cash proceeds of $20.3 million.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company has commitments including purchase obligations for web-hosting services and other commitments for brand marketing. As of September 30, 2022, there were no material changes outside the ordinary course of business to the Company’s commitments, as disclosed in its Annual Report on Form 10-K for the year ended December 31, 2021. Extenuating Circumstances Policy In March 2020, the Company applied its extenuating circumstances policy to cancellations resulting from COVID-19. That policy provides customers with greater flexibility to cancel reservations that are disrupted by epidemics, natural disasters, and other emergencies. Specifically, accommodation bookings made by guests on or before March 14, 2020, have so far been covered by the policy and may be canceled before check-in. To support Hosts impacted by elevated guest cancellations under that policy, the Company committed up to $250.0 million for Hosts, and had a remaining reserve balance of $37.8 million as of September 30, 2022. The reservations eligible for this $250.0 million Host program were defined as reservations made on or before March 14, 2020 with a check-in date between March 14, 2020 and May 31, 2020. For these reservations, eligible Hosts are entitled to receive 25% of the amount they would have received from guests under the Host’s cancellation policies. These payments are accounted for as consideration paid to a customer and as such, primarily result in a reduction to revenue. Under this policy, the Company recorded payments, primarily to Hosts, that were not material for the three and nine months ended September 30, 2021 and 2022, in its condensed consolidated statement of operations. Lodging Tax Obligations and Other Non-Income Tax Matters Some states and localities in the United States and elsewhere in the world impose transient occupancy or lodging accommodations taxes (“Lodging Taxes”) on the use or occupancy of lodging accommodations or other traveler services. As of September 30, 2022, the Company collects and remits Lodging Taxes in approximately 31,300 jurisdictions on behalf of its Hosts. Such Lodging Taxes are generally remitted to tax jurisdictions within a 30 to 90-day period following the end of each month. As of December 31, 2021 and September 30, 2022, the Company had an obligation to remit Lodging Taxes collected from guests on bookings in these jurisdictions totaling $180.8 million and $327.9 million, respectively. These payables were recorded in accrued expenses and other current liabilities on the condensed consolidated balance sheets. In jurisdictions where the Company does not collect and remit Lodging Taxes, the responsibility for collecting and remitting these taxes primarily rests with Hosts. The Company has estimated liabilities in a certain number of jurisdictions with respect to state, city, and local taxes related to lodging where management believes it is probable that the Company can be held jointly liable with Hosts for taxes and the related amounts can be reasonably estimated. As of December 31, 2021 and September 30, 2022, accrued obligations related to these estimated taxes, including estimated penalties and interest, totaled $57.3 million and $64.7 million, respectively. With respect to lodging and related taxes for which a loss is probable or reasonably possible, the Company is unable to determine an estimate of the possible loss or range of loss beyond the amounts already accrued. The Company’s potential obligations with respect to Lodging Taxes could be affected by various factors, which include, but are not limited to, whether the Company determines, or any tax authority asserts, that the Company has a responsibility to collect lodging and related taxes on either historical or future transactions or by the introduction of new ordinances and taxes which subject the Company’s operations to such taxes. Accordingly, the ultimate resolution of Lodging Taxes may be greater or less than reserve amounts that the Company has recorded. The Company is currently involved in disputes with certain states and localities involving the payment of Lodging Taxes. These jurisdictions are asserting that the Company is liable or jointly liable with Hosts to collect and remit Lodging Taxes. These disputes are in various stages and the Company continues to vigorously defend these claims. The Company believes that the statutes at issue impose a Lodging Tax obligation on the person exercising the taxable privilege of providing accommodations, or the Company’s Hosts. The imposition of such taxes on the Company could increase the cost of a guest booking and potentially cause a reduction in the volume of bookings on the Company’s platform, which would adversely impact the Company’s results of operations. The Company will continue to monitor the application and interpretation of lodging and related taxes and ordinances and will adjust accruals based on any new information or further developments. The Company is under audit and inquiry by various domestic and foreign tax authorities with regard to non-income tax matters. The subject matter of these contingent liabilities primarily arises from the Company’s transactions with its customers, as well as the tax treatment of certain employee benefits and related employment taxes. In jurisdictions with disputes connected to transactions with customers , disputes involve the applicability of transactional taxes (such as sales, value-added, and similar taxes) to services provided, as well as the applicability of withholding tax on payments made to such Hosts. Due to the inherent complexity and uncertainty of these matters and judicial processes in certain jurisdictions, the final outcomes may exceed the estimated liabilities recorded. As of December 31, 2021 and September 30, 2022, the Company accrued a total of $124.2 million and $132.9 million of estimated tax liabilities, including interest, related to Hosts’ withholding tax obligations, respectively. The Company has identified reasonably possible exposures related to withholding income taxes and transactional taxes, and has not accrued for these amounts since the likelihood of the contingent liability is less than probable. The Company estimates that the reasonably possible loss related to these matters in excess of the amounts accrued is between $165.0 million to $185.0 million; however, no assurance can be given as to the outcomes and the Company could be subject to significant additional tax liabilities. With respect to all other withholding tax on payments made to Hosts and transactional taxes for which a loss is probable or reasonably possible, the Company is unable to determine an estimate of the possible loss or range of loss beyond the amounts already accrued. In addition, as of December 31, 2021 and September 30, 2022, the Company accrued a total of $33.6 million and $33.4 million of estimated tax liabilities related to employment taxes on certain employee benefits, respectively. The Company is subject to regular payroll tax examinations by various state and local jurisdictions. Although management believes its tax withholding remittance practices are appropriate, the Company may be subject to additional tax liabilities, including interest and penalties, if any tax authority disagrees with the Company’s withholding and remittance practices, or if there are changes in laws, regulations, administrative practices, principles or interpretations related to payroll tax withholding in the various state and local jurisdictions. Legal and Regulatory Matters The Company has been and is currently a party to various legal and regulatory matters arising in the normal course of business. Such proceedings and claims, even if not meritorious, can require significant financial and operational resources, including the diversion of management’s attention from the Company’s business objectives. Regulatory Matters The Company operates in a complex legal and regulatory environment and its operations are subject to various U.S. and foreign laws, rules, and regulations, including those related to: Internet activities; short-term rentals, long-term rentals and home sharing; real estate, property rights, housing and land use; travel and hospitality; privacy and data protection; intellectual property; competition; health and safety; protection of minors; consumer protection; employment; payments, money transmission, economic and trade sanctions, anti-corruption and anti-bribery; taxation; and others. In addition, the nature of the Company’s business exposes it to inquiries and potential claims related to the compliance of the business with applicable law and regulations. In some instances, applicable laws and regulations do not yet exist or are being applied, interpreted or implemented to address aspects of the Company’s business, and such adoption or interpretation could further alter or impact the Company’s business. Intellectual Property The Company has been and is currently subject to claims relating to intellectual property, including alleged patent infringement. Adverse results in such lawsuits may include awards of substantial monetary damages, costly royalty or licensing agreements, or orders preventing the Company from offering certain features, functionalities, products, or services, and may also cause the Company to change its business practices or require development of non-infringing products or technologies, which could result in a loss of revenue or otherwise harm its business. To date, the Company has not incurred any material costs as a result of such cases and has not recorded any material liabilities in its condensed consolidated financial statements related to such matters. Litigation and Other Legal Proceedings The Company is currently involved in, and may in the future be involved in, legal proceedings, claims, and government investigations in the ordinary course of business. These include proceedings, claims, and investigations relating to, among other things, regulatory matters, commercial matters, intellectual property, competition, tax, employment, pricing, discrimination, consumer rights, personal injury, and property rights. The Australian Competition and Consumer Commission (“ACCC”) commenced proceedings against Airbnb, Inc. and Airbnb Ireland UC alleging that Airbnb has breached the Australian Consumer Law by making false and misleading representations, because certain users were shown prices and charged in U.S. dollars versus Australian dollars. The Company disputes the allegations of the ACCC. Depending on the nature of the proceeding, claim, or investigation, the Company may be subject to monetary damage awards, fines, penalties, or injunctive orders. Furthermore, the outcome of these matters could materially adversely affect the Company’s business, results of operations, and financial condition. The outcomes of legal proceedings, claims, and government investigations are inherently unpredictable and subject to significant judgment to determine the likelihood and amount of loss related to such matters. While it is not possible to determine the outcomes, the Company believes based on its current knowledge that the resolution of all such pending matters will not, either individually or in the aggregate, have a material adverse effect on the Company’s business, results of operations, financial condition, or cash flows. The Company establishes an accrued liability for loss contingencies related to legal matters when a loss is both probable and reasonably estimable. These accruals represent management’s best estimate of probable losses. Such currently accrued amounts are not material to the Company’s condensed consolidated financial statements. However, management’s views and estimates related to these matters may change in the future, as new events and circumstances arise and the matters continue to develop. Until the final resolution of legal matters, there may be an exposure to losses in excess of the amounts accrued. With respect to outstanding legal matters, based on current knowledge, the amount or range of reasonably possible loss will not, either individually or in the aggregate, have a material adverse effect on the Company’s business, results of operations, financial condition, or cash flows. Legal fees are expensed as incurred. Host Protections The Company offers AirCover coverage, which includes but is not limited to, the Company’s Host Damage Protection program that provides protection of up to $1.0 million for direct physical loss or damage to a Host’s covered property caused by guests during a confirmed booking and when the Host and guest are unable to resolve the dispute. The Company retains risk and also maintains insurance from third parties on a per claim basis to protect the Company’s financial exposure under this program. In addition, through third-party insurers and self-insurance mechanisms, including a wholly-owned captive insurance subsidiary created during the year ended December 31, 2019, the Company provides insurance coverage for third-party bodily injury or property damage liability claims that occur during a stay. The Company’s Host Liability Insurance and Experiences Liability Insurance consists of a commercial general liability policy, with Hosts and the Company as named insureds and landlords of Hosts as additional insureds. The Host Liability Insurance and Experiences Liability Insurance provides primary coverage for up to $1.0 million per occurrence, subject to a $1.0 million cap per listing location, and includes various market standard conditions, limitations, and exclusions. Indemnifications The Company has entered into indemnification agreements with certain of its officers and directors. The indemnification agreements and the Company’s Amended and Restated Bylaws (the “Bylaws”) require the Company to indemnify these individuals to the fullest extent not prohibited by Delaware law. Subject to certain limitations, the indemnification agreements and Bylaws also require the Company to advance expenses incurred by its directors and officers. No demands have been made upon the Company to provide indemnification under the indemnification agreements or the Bylaws, and thus, there are no claims that the Company is aware of that could have a material adverse effect on the Company’s business, results of operations, financial condition, or cash flows. In the ordinary course of business, the Company has included limited indemnification provisions under certain agreements with parties with whom the Company has commercial relations of varying scope and terms with respect to certain matters, including losses arising out of its breach of such agreements or out of intellectual property infringement claims made by third parties. It is not possible to determine the maximum potential loss under these indemnification provisions due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular provision. To date, no significant costs have been incurred, either individually or collectively, in connection with the Company’s indemnification provisions.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s tax provision for interim periods is determined by using an estimated annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, the Company updates the estimated annual effective tax rate and makes a year-to-date adjustment to the provision. The estimated annual effective tax rate is subject to significant volatility due to several factors, including accurately predicting the Company’s pre-tax and taxable income and loss and the mix of jurisdictions to which they relate, intercompany transactions, audit-related developments, and changes in statutes, regulations, case law, and administrative actions. The Company recorded income tax expense of $16.6 million and $55.6 million for the three months ended September 30, 2021 and 2022, respectively, and $34.1 million and $70.6 million for the nine months ended September 30, 2021 and 2022, respectively. Tax expense for all periods was primarily driven by current tax on U.S. and foreign earnings. The Company’s significant tax jurisdictions include the United States, California, and Ireland. The Company is currently under examination for income taxes by the Internal Revenue Service (“IRS”) for the 2013, 2016, 2017, and 2018 tax years. The primary issue under examination in the 2013 audit is the valuation of the Company’s international intellectual property which was sold to a subsidiary in 2013. In the year ended December 31, 2019, new information became available which required the Company to remeasure its reserve for unrecognized tax benefits. The Company recorded additional tax expense of $196.4 million during the year ended December 31, 2019. In December 2020, the Company received a Notice of Proposed Adjustment (“NOPA”) from the IRS which proposed an increase to the Company’s U.S. taxable income that could result in additional income tax expense and cash liability of $1.3 billion, plus penalties and interest, which exceeds its current reserve recorded in its consolidated financial statements by more than $1.0 billion. The Company disagrees with the proposed adjustment and intends to vigorously contest it. In February 2021, the Company submitted a protest to the IRS describing its disagreement with the proposed agreement and requesting the case to be transferred to the IRS Independent Office of Appeals (“IRS Appeals”). In December 2021, the Company received a rebuttal from the IRS with the same proposed adjustments that were in the NOPA. In January 2022, the Company entered into an administrative dispute process with IRS Appeals. The Company will continue to pursue all available remedies to resolve this dispute, including petitioning the U.S. Tax Court (“Tax Court”) for redetermination if an acceptable outcome cannot be reached with IRS Appeals, and if necessary, appealing the Tax Court’s decision to the appropriate appellate court. On August 16, 2022, the Inflation Reduction Act of 2022 was signed into law, with tax provisions primarily focused on implementing a 15%

Each share of Class A common stock is entitled to one vote per share and each share of Class B common stock is entitled to 20 votes per share. Each share of Class B common stock is convertible into a share of Class A common stock voluntarily at any time by the holder, and automatically upon certain events. The Class A common stock has no conversion rights. As the liquidation and dividend rights are identical for Class A and Class B common stock, the undistributed earnings are allocated on a proportional basis and the resulting net income (loss) per share attributable to common stockholders is the same for both Class A and Class B common stock on an individual or combined basis. There were no preferred dividends declared or accumulated for the three and nine months ended September 30, 2021 and 2022. As of September 30, 2021 and 2022, RSUs to be settled in 10.8 million and 9.6 million shares of Class A common stock were excluded from the table below because they are subject to market conditions that were not achieved as of such date. As of September 30, 2021 and 2022, 0.5 million shares of RSAs were excluded from the table below because they are subject to performance conditions that were not achieved as of such date. Additionally, the following securities were not included in the computation of diluted shares outstanding because the effect would be anti-dilutive (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2021 2022 2021 2022 2026 Notes (1) — — 11,086 — Warrants — — 7,935 — Escrow shares 74 74 74 74 Stock options 550 1,128 27,773 1,128 RSUs 4,777 10,266 29,816 8,292 RSAs — — 148 — ESPP 109 — 594 — Total 5,510 11,468 77,426 9,494 (1) Holders of the 2026 Notes who convert their 2026 Notes in connection with certain corporate events that constitute a make-whole fundamental change are entitled to an increase in the conversion rate. The 11.1 million shares represents the maximum number of shares that can be issued upon conversion after considering the make-whole fundamental change adjustment on an unweighted basis. On August 2, 2022, the Company announced its board of directors approved a share repurchase program with authorization to purchase up to $2.0 billion of the Company's Class A common stock at management’s discretion (the “Share Repurchase Program”). Share repurchases under the Share Repurchase Program may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades or accelerated share repurchase transactions or by any combination of such methods. The Share Repurchase Program does not have an expiration date, does not obligate the Company to repurchase any specific number of shares, and may be modified, suspended or terminated at any time at the Company’s discretion. When shares are retired, the value of repurchased shares is deducted from stockholders’ equity through capital with the excess over par value recorded to accumulated deficit. During the three months ended September 30, 2022, the Company repurchased and subsequently retired 8.6 million shares of common stock for $1.0 billion. As of September 30, 2022, the Company had $1.0 billion available to repurchase shares pursuant to the Share Repurchase Program.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring During the year ended December 31, 2020, the Company experienced significant economic challenges associated with a severe decline in bookings, resulting primarily from COVID-19 and overall global travel restrictions. To address these impacts, in May 2020, the Company’s management approved a restructuring plan to realign the Company’s business and strategic priorities based on the current market and economic conditions as a result of COVID-19. This worldwide restructuring plan included a 25% reduction in the number of full-time employees, or approximately 1,800 employees, as well as a reduction in the contingent workforce and amendments to certain commercial agreements. These restructuring expenses are included in the Company’s condensed consolidated statements of operations, and unpaid amounts are included in accrued expenses and other current liabilities on its condensed consolidated balance sheets. Cumulative restructuring charges as of September 30, 2022 were $353.3 million. As of September 30, 2022, the remaining liability for restructuring costs was not material.

The 2022 Credit Facility provides a $200.0 million sub-limit for the issuance of letters of credit. The 2022 Credit Facility has a commitment fee based on ratings and leverage ratios with amounts that range from 0.10% to 0.20% per annum on any undrawn amounts, payable quarterly in arrears. Interest on borrowings is based on ratings and leverage ratios with amounts that range from (i) in the case of the Secured Overnight Financing Rate (“SOFR”) borrowings, 1.0% to 1.5%, plus SOFR, subject to a floor of 0.0%, or (ii) in the case of base rate borrowings, 0.0% to 0.5%; plus the greatest of (a) the rate of interest in effect for such day by Morgan Stanley Senior Funding, Inc. as its “prime rate”; (b) the federal funds effective rate plus 0.5%; and (c) SOFR for a one-month period plus 1.0%. Outstanding balances may be repaid prior to maturity without penalty. The 2022 Credit Facility contains customary events of default, affirmative and negative covenants, including restrictions on the Company’s and certain of its subsidiaries’ ability to incur debt and liens, undergo fundamental changes, as well as certain financial covenants. In connection with the consummation of the 2022 Credit Facility, the Company terminated the 2020 Credit Facility. As of the date of this Quarterly Report on Form 10-Q, no amounts were drawn under the 2022 Credit Facility.

Summary of Significant Accounting Policies (Policies)	Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements (“condensed consolidated financial statements”) have been prepared in conformity with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding interim financial information. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K, filed with the SEC on February 25, 2022. There have been no changes to the Company’s significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2021 that have had a material impact on the Company’s condensed consolidated financial statements and related notes. The results for the interim periods are not necessarily indicative of results for the full year. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods.
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries and variable interest entities (“VIE”) in which the Company is the primary beneficiary in accordance with consolidation accounting guidance. All intercompany transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. The Company regularly evaluates its estimates, including those related to bad debt reserves, fair value of investments, useful lives of long-lived assets and intangible assets, valuation of goodwill and intangible assets from acquisitions, contingent liabilities, insurance reserves, revenue recognition, valuation of common stock, stock-based compensation, and income and non-income taxes, among others. Actual results could differ materially from these estimates. As the impact of the coronavirus disease (“COVID-19”) pandemic and the challenging macroeconomic conditions, including rising inflation and interest rates, depressed consumer spending, and the strengthening of the U.S. dollar relative to certain foreign currencies, continues to evolve, estimates and assumptions about future events and their effects cannot be determined with certainty and therefore require increased judgment. These estimates and assumptions may change in future periods and will be recognized in the consolidated financial statements as new events occur and additional information becomes known. To the extent the Company’s actual results differ materially from those estimates and assumptions, the Company’s future consolidated financial statements could be affected.
Recently Adopted Accounting Standards and Recently Issued Accounting Standards Not Yet Adopted	Recently Adopted Accounting Standards In May 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-04, Earnings Per Share (Topic 260), Debt - Modifications and Extinguishments (Topic 470-50), Compensation - Stock Compensation (Topic 718), and Derivatives and Hedging - Contracts in Entity's Own Equity (Subtopic 815-40) , which clarifies existing guidance for freestanding written call options which are equity classified and remain so after they are modified or exchanged in order to reduce diversity in practice. The standard is effective for public entities in fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. The Company adopted the standard during the first quarter of 2022, which did not have an impact on the Company's condensed consolidated financial statements. Recently Issued Accounting Standards Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) , which provides optional expedients and exceptions to contract modifications and hedging relationships that reference the London Interbank Offered Rate or another reference rate expected to be discontinued. The standard is effective upon issuance and may be applied at the beginning of the interim period that includes March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, which clarified the scope of Topic 848 to include derivatives that are affected by a change in the interest rate used for margining, discounting, or contract price alignment that do not also reference London Interbank Offered Rate or another reference rate that is expected to be discontinued as a result of the reference rate reform. The standard is effective upon issuance and may be applied retroactively as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively to any new modifications within an interim period including or subsequent to January 7, 2021. The Company is evaluating the impact on the Company’s consolidated financial statements. In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815) , which clarifies the guidance on fair value hedge accounting of interest rate risk for portfolios of financial assets. The standard is effective for public entities in fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted on any date on or after the issuance of ASU 2017-12. The Company is evaluating the impact on the Company’s consolidated financial statements. In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the guidance of equity securities that are subject to a contractual sale restriction as well as includes specific disclosure requirements for such equity securities. The standard is effective for public entities in fiscal years beginning after December 15, 2023, including interim periods within those fiscal years and will be applied prospectively. Early adoption is permitted. The Company is evaluating the impact on the Company’s consolidated financial statements. There are other new accounting pronouncements issued by the FASB that the Company has adopted or will adopt, as applicable, and the Company does not believe any of these accounting pronouncements have had, or will have, a material impact on its consolidated financial statements or disclosures.
Revision of Previously Issued Financial Statements	Revision of Previously Issued Financial StatementsThe condensed consolidated statements of cash flows for the nine months ended September 30, 2021 has been revised to correct for errors identified by management during the preparation of the financial statements for the three months ended March 31, 2022. The errors understated cash flows from operating activities by $122 million and overstated the cash flows from financing activities by $122 million for the nine months ended September 30, 2021. Management has determined that these errors did not result in the previously issued financial statements being materially misstated. These errors primarily related to the timing of tax payments from the net settlement of equity awards at the initial public offering in December 2020. In particular, in 2020, the Company reported $1.7 billion of cash used in financing activities to cover taxes paid related to the net share settlement of its equity awards that vested upon the initial public offering. However, approximately $123 million of this amount was actually remitted to taxing authorities in foreign jurisdictions during the nine months ended September 30, 2021. This had no impact on the Company’s condensed consolidated financial statements outside of the presentation in the condensed consolidated statements of cash flow and did not affect the condensed consolidated balance sheets, condensed consolidated statements of operations or condensed consolidated statements of stockholders’ equity.
Share repurchases	Share repurchases under the Share Repurchase Program may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades or accelerated share repurchase transactions or by any combination of such methods. The Share Repurchase Program does not have an expiration date, does not obligate the Company to repurchase any specific number of shares, and may be modified, suspended or terminated at any time at the Company’s discretion. When shares are retired, the value of repurchased shares is deducted from stockholders’ equity through capital with the excess over par value recorded to accumulated deficit.
