[1]	Certain shares related to share-based compensation were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive under the treasury stock method, including less than 1 million shares for the three and six months ended June 30, 2021, and, as revised, 4 million and 3 million shares for the three and six months ended June 30, 2020, respectively. The dilutive shares related to share-based compensation included in the previously reported weighted average shares outstanding of 278 million and 279 million for the three and six months ended June 30, 2020, respectively, were revised in the current period presentation, as the previously reported dilutive shares were determined to be anti-dilutive as a result of the net loss attributable to Hilton stockholders reported during those periods. The result of the revision is an immaterial decrease in the previously reported diluted EPS for the six months ended June 30, 2020 of $0.01, with no change to the diluted EPS previously reported for the three months ended June 30, 2020.

Organization and Basis of Presentation	Organization and Basis of Presentation Organization Hilton Worldwide Holdings Inc. (the "Parent," or together with its subsidiaries, "Hilton," "we," "us," "our" or the "Company"), a Delaware corporation, is one of the largest hospitality companies in the world and is engaged in managing, franchising, owning and leasing hotels and resorts, and licensing its brands and intellectual property ("IP"). As of June 30, 2021, we managed, franchised, owned or leased 6,676 hotels and resorts, including timeshare properties, totaling 1,050,331 rooms in 119 countries and territories. Basis of Presentation The accompanying condensed consolidated financial statements for the three and six months ended June 30, 2021 and 2020 have been prepared in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP") and are unaudited. We have condensed or omitted certain disclosures normally included in annual financial statements presented in accordance with GAAP but that are not required for interim reporting purposes. Although we believe the disclosures made are adequate to prevent the information presented from being misleading, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Revenues from Contracts with Customers	Revenues from Contracts with Customers Contract Liabilities The following table summarizes the activity of our contract liabilities, which are classified as components of current and long-term deferred revenues, during the six months ended June 30, 2021: (in millions) Balance as of December 31, 2020 $ 1,312 Cash received in advance and not recognized as revenue 65 Revenue recognized (1) (114) Other (2) (123) Balance as of June 30, 2021 $ 1,140 ____________ (1) Includes $88 million related to Hilton Honors, our guest loyalty program. Revenue recognized during the three months ended June 30, 2021 and 2020, was $54 million and $56 million, respectively, and, during the six months ended June 30, 2020, was $110 million. (2) Primarily represents changes in estimated transaction prices for our performance obligations related to points issued under Hilton Honors, which had no effect on revenues. Hilton Honors Points Pre-Sale In April 2020, we pre-sold Hilton Honors points to American Express for $1.0 billion in cash (the "Honors Points Pre-Sale"). American Express and their respective designees may use the points in connection with Hilton Honors co-branded credit cards and for promotions, rewards and incentive programs or certain other activities that they may establish or engage in from time to time. Upon receipt of the cash, we recognized $636 million in deferred revenues and the remainder in liability for guest loyalty program; see below for additional information on the revenue recognition of the related deferred revenues. Performance Obligations As of June 30, 2021, we had deferred revenues for unsatisfied performance obligations consisting of: (i) $210 million related to Hilton Honors that will be recognized as revenue when the points are redeemed, which we estimate will occur over approximately the next two years; (ii) $323 million related to co-branded credit card arrangements, primarily from the Honors Points Pre-Sale, of which a portion will be recognized as revenue when points are awarded with the remaining portion recognized as revenue when the points are redeemed; and (iii) $607 million related to application, initiation and other fees that is expected to be recognized as revenue over the terms of the related contracts. Incentive Management Fees We update our estimates of the expected achievement of incentive management fee targets, generally measured over one- calendar year, each reporting period and constrain the recognition of revenue to the extent that we do not expect to achieve the thresholds as specified in our management contracts with incentive fees. During the three months ended June 30, 2020, we reversed certain incentive fees that were recognized during the three months ended March 31, 2020, due to revisions of the estimates that were used during that reporting period.

Consolidated Variable Interest Entities Disclosure [Abstract]
Consolidated Variable Interest Entities	Consolidated Variable Interest Entities As of June 30, 2021 and December 31, 2020, we consolidated two variable interest entities ("VIEs") that each lease a hotel property. We consolidated these VIEs since we are the primary beneficiary, having the power to direct the activities that most significantly affect their economic performance. Additionally, we have the obligation to absorb losses and the right to receive benefits that could be significant to them. The assets of our consolidated VIEs are only available to settle the obligations of the respective entities and the liabilities of the consolidated VIEs are non-recourse to us. Our condensed consolidated balance sheets include the assets and liabilities of these entities, which primarily comprised the following: June 30, December 31, 2021 2020 (in millions) Cash and cash equivalents $ 18 $ 40 Property and equipment, net 66 76 Deferred income tax assets 57 57 Other non-current assets 61 66 Accounts payable, accrued expenses and other 24 27 Long-term debt (1) 180 203 Other long-term liabilities 17 17 ____________ (1) Includes finance lease liabilities of $163 million and $184 million as of June 30, 2021 and December 31, 2020, respectively. As of June 30, 2021, the VIEs had revolving credit facilities with borrowing capacities totaling 4.5 billion Japanese yen (equivalent to $41 million as of such date), and there were no amounts drawn under these facilities as of June 30, 2021 or December 31, 2020.

Our senior secured credit facilities consist of a $1.75 billion senior secured revolving credit facility (the "Revolving Credit Facility") and a senior secured term loan facility (the "Term Loan"). The obligations of our senior secured credit facilities are unconditionally and irrevocably guaranteed by the Parent and substantially all of its direct and indirect wholly owned domestic restricted subsidiaries. During the six months ended June 30, 2021, we fully repaid the $1,690 million outstanding debt balance on the Revolving Credit Facility, including $1,190 million during the three months ended June 30, 2021. As of June 30, 2021, we had $60 million of letters of credit outstanding on the Revolving Credit Facility, resulting in an available borrowing capacity of $1,690 million. In February 2021, we issued $1.5 billion aggregate principal amount of 3.625% Senior Notes due 2032 (the "2032 Senior Notes") and incurred $21 million of debt issuance costs. Interest on the 2032 Senior Notes is payable semi-annually in arrears on February 15 and August 15 of each year, beginning August 15, 2021. We used the net proceeds from the issuance, together with available cash, to redeem all $1.5 billion in aggregate principal amount of our outstanding 5.125% Senior Notes due 2026 (the "2026 Senior Notes"), plus accrued and unpaid interest. In connection with the redemption, we paid a redemption premium of $55 million and accelerated the recognition of the unamortized deferred financing costs related to the 2026 Senior Notes of $14 million, which were both included in loss on debt extinguishment in our condensed consolidated statement of operations for the six months ended June 30, 2021.

The carrying values and fair values exclude finance lease liabilities and other debt of consolidated VIEs. We measure our interest rate swaps at fair value, which was determined using a discounted cash flow analysis that reflects the contractual terms of the interest rate swaps, including the period to maturity, and uses observable market-based inputs of similar instruments, including interest rate curves, as applicable. Our interest rate swaps are included in other long-term liabilities in our condensed consolidated balance sheets. The fair values of financial instruments not included in these tables are estimated to be equal to their carrying values as of June 30, 2021 and December 31, 2020.

Income Taxes

Income Taxes	Jun. 30, 2021
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's income tax provision for interim reporting periods has historically been calculated by applying an estimate of the annual effective income tax rate for the full year to "ordinary" income (loss) for the interim reporting period, which is calculated as pre-tax income (loss) excluding unusual and infrequently occurring discrete items. For the six months ended June 30, 2021, we calculated the income tax provision using a discrete effective income tax rate method as if the interim year to date period was an annual period. We determined that since normal changes in estimated "ordinary" income (loss) would result in disproportionate changes in the estimated annual effective income tax rate, the Company's historical method of calculating its income tax provision for interim reporting periods would not provide a reliable estimate for the six months ended June 30, 2021. In June 2021, the United Kingdom's ("U.K.") Finance Act 2021 (the "U.K. Finance Act") was enacted, which included, among other items, an increase to the U.K. corporate income tax rate from 19 percent to 25 percent. We remeasured our U.K. deferred tax assets and other tax liabilities to the new rate, resulting in a $30 million tax benefit recognized for the three and six months ended June 30, 2021. Due to this remeasurement, our effective income tax rate on consolidated pre-tax loss is higher than the combined U.S. statutory rate for the six months ended June 30, 2021. We file income tax returns, including returns for our subsidiaries, with federal, state, local and foreign tax jurisdictions. We are under regular and recurring audit by the Internal Revenue Service ("IRS") and other taxing authorities on open tax positions. The timing of the resolution of tax audits is highly uncertain, as are the amounts, if any, that may ultimately be paid upon such resolution. Changes may result from the conclusion of ongoing audits, appeals or litigation in federal, state, local and foreign tax jurisdictions or from the resolution of various proceedings between the U.S. and foreign tax authorities. As of June 30, 2021, we remain subject to federal and state examinations of our income tax returns for tax years from 2005 through 2019 and foreign examinations of our income tax returns for tax years from 1996 through 2020. Our total unrecognized tax benefits as of June 30, 2021 and December 31, 2020 were $442 million and $451 million, respectively. As of June 30, 2021 and December 31, 2020, we had accrued approximately $70 million and $65 million, respectively, for interest and penalties related to these unrecognized tax benefits. Included in the balances of unrecognized tax benefits as of June 30, 2021 and December 31, 2020 were $402 million and $400 million, respectively, associated with positions that, if favorably resolved, would provide a benefit to our effective income tax rate. In prior periods, we received 30-day Letters from the IRS and the Revenue Agents Reports ("RARs") for the 2006 through the 2013 tax years. We disagreed with several of the proposed adjustments in the RARs and filed formal appeals protests with the IRS. The unsettled proposed adjustments sought by the IRS for the tax years with open audits would result in additional U.S. federal taxes owed of approximately $817 million, excluding interest and penalties and potential state income taxes. We disagree with the IRS's position on each of their assertions and intend to vigorously contest them. However, based on continuing appeals process discussions with the IRS, we believe that it is more likely than not that we will not recognize the full benefit related to certain of the issues being appealed. Accordingly, as of June 30, 2021, we had recorded $88 million of unrecognized tax benefits related to these issues.

Share-Based Compensation

Share-Based Compensation	Jun. 30, 2021
Share-based Payment Arrangement [Abstract]
Share-Based Compensation	Share-Based Compensation Under the Hilton 2017 Omnibus Incentive Plan (the "2017 Plan"), we award time-vesting restricted stock units ("RSUs"), nonqualified stock options ("options") and performance-vesting RSUs ("performance shares") to our eligible employees. We recognized share-based compensation expense of $53 million and $24 million during the three months ended June 30, 2021 and 2020, respectively, and $92 million and $12 million during the six months ended June 30, 2021 and 2020, respectively, which included amounts reimbursed by hotel owners. The expenses recognized during the three and six months ended June 30, 2020 were net of the reversal of expenses recognized in prior periods as a result of the determination that the performance conditions of the performance shares that were originally awarded in 2018 and 2019 were no longer probable of achievement. As of June 30, 2021, unrecognized compensation costs for unvested awards under the 2017 Plan were approximately $185 million, which are expected to be recognized over a weighted-average period of 1.7 years on a straight-line basis. RSUs During the six months ended June 30, 2021, we granted 573,000 RSUs with a weighted average grant date fair value per share of $123.03, which vest in equal annual installments over two three Options During the six months ended June 30, 2021, we granted 361,000 options with an exercise price per share of $123.13, which vest in equal annual installments over three years from the date of grant and terminate 10 years from the date of grant or earlier if the individual’s service terminates under certain circumstances. The grant date fair value per share of the options granted during the six months ended June 30, 2021 was $41.15, which was determined using the Black-Scholes-Merton option-pricing model with the following assumptions: Expected volatility (1) 33.13 % Dividend yield (2) — % Risk-free rate (3) 0.92 % Expected term (in years) (4) 6.0 ____________ (1) Estimated using a blended approach of historical and implied volatility. Historical volatility is based on the historical movement of Hilton's stock price for a period that corresponds to the expected life of the option. (2) We have historically paid regular quarterly cash dividends. However, in March 2020, we suspended the declaration and payment of dividends as part of certain proactive measures we took to secure our liquidity position in response to the COVID-19 pandemic, and, at the time of the grant, we could not estimate when the payment of dividends would resume. (3) Based on the yields of U.S. Department of Treasury instruments with similar expected lives. (4) Estimated using the average of the vesting periods and the contractual term of the options. Performance Shares In December 2020, we modified our performance shares that were originally awarded in 2018, 2019 and 2020 in response to the COVID-19 pandemic and its negative impact on the hospitality industry and, ultimately, the Company's performance. The modifications were structured to reward for results achieved prior to the COVID-19 pandemic, retain senior business leaders and incentivize for the recovery efforts by utilizing metrics most meaningful in assessing our performance during our recovery from the adverse impact of the pandemic. Under the terms of the modified awards, a portion of the outstanding performance shares granted in 2019 (the "2019 performance shares") were modified to vest based on performance prior to the pandemic and continued service, and the remaining portion of those performance shares, as well as the performance shares granted in 2020 (the "2020 performance shares"), were converted to performance shares that will vest based on different performance measures from those under the original award agreements. The modified terms did not change the vesting schedules of the original awards. During the six months ended June 30, 2021, we granted 241,000 performance shares (the "2021 performance shares") with a grant date fair value per share of $123.13. We recognize compensation expense based on the total number of performance shares that are expected to vest as determined by the performance measures' achievement factors, which are estimated each reporting period and range from zero percent to 200 percent, with 100 percent being the target. As of June 30, 2021, we determined that the performance measures for all of the outstanding performance shares were probable of achievement, with the applicable achievement factors estimated to be between the target and maximum percentages for the 2019 performance shares and at target for the 2020 performance shares and the 2021 performance shares.

The dilutive shares related to share-based compensation included in the previously reported weighted average shares outstanding of 278 million and 279 million for the three and six months ended June 30, 2020, respectively, were revised in the current period presentation, as the previously reported dilutive shares were determined to be anti-dilutive as a result of the net loss attributable to Hilton stockholders reported during those periods. The result of the revision is an immaterial decrease in the previously reported diluted EPS for the six months ended June 30, 2020 of $0.01, with no change to the diluted EPS previously reported for the three months ended June 30, 2020.

Business Segments	Jun. 30, 2021
Segment Reporting [Abstract]
Business Segments	Business Segments We are a hospitality company with operations organized in two distinct operating segments: (i) management and franchise and (ii) ownership. These segments are managed and reported separately because of their distinct economic characteristics. The management and franchise segment includes all of the hotels we manage for third-party owners, as well as all franchised hotels that license our brands and where we provide other prescribed services, but where the day-to-day services of the hotels are operated or managed by someone other than us. This segment also earns licensing fees from Hilton Grand Vacations Inc. ("HGV") and strategic partnerships, including co-branded credit card arrangements, for the right to use certain Hilton marks and IP, as well as fees for managing properties in our ownership segment. As of June 30, 2021, this segment included 723 managed hotels and 5,836 franchised hotels consisting of 1,021,969 total rooms. As a result of the COVID-19 pandemic, during the six months ended June 30, 2021 and 2020, the operations of certain hotels in our management and franchise segment were suspended for some period of time. As of June 30, 2021, all but approximately 100 of these hotels were open. As of June 30, 2021, our ownership segment included 60 properties totaling 19,185 rooms. The segment comprised 52 hotels that we wholly owned or leased, one hotel owned by a consolidated non-wholly owned entity, two hotels that were each leased by a consolidated VIE and five hotels owned or leased by unconsolidated affiliates. As a result of the COVID-19 pandemic, certain hotels in our ownership segment began suspending operations in March 2020; however, as of June 30, 2021, with the exception of one hotel owned by an unconsolidated affiliate, all of the hotels in our ownership segment were open. During 2020, we recognized impairment losses in our condensed consolidated statements of operations related to certain hotel properties in our ownership segment under operating and finance leases, which included $6 million and $51 million of operating lease right-of-use ("ROU") assets during the three and six months ended June 30, 2020, respectively, and, during the six months ended June 30, 2020, $21 million of property and equipment, net, of which $2 million related to finance lease ROU assets, and $46 million of other intangible assets. The performance of our operating segments is evaluated primarily on operating income (loss), without allocating other revenues and other expenses from managed and franchised properties, other revenues, other expenses or general and administrative expenses. The following table presents revenues for our reportable segments, reconciled to consolidated amounts: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 (in millions) Franchise and licensing fees $ 372 $ 134 $ 617 $ 476 Base and other management fees (1) 48 12 78 78 Incentive management fees 21 (5) 34 18 Management and franchise 441 141 729 572 Ownership 121 31 177 241 Segment revenues 562 172 906 813 Amortization of contract acquisition costs (7) (7) (14) (15) Other revenues 21 10 38 33 Direct reimbursements from managed and franchised properties (2) 329 196 552 941 Indirect reimbursements from managed and franchised properties (2) 426 192 724 712 Intersegment fees elimination (1) (2) 1 (3) — Total revenues $ 1,329 $ 564 $ 2,203 $ 2,484 ____________ (1) Includes management, royalty and IP fees charged to our ownership segment by our management and franchise segment, which were eliminated in our condensed consolidated statements of operations.

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We provide performance guarantees to certain owners of hotels that we operate under management contracts. Most of these guarantees do not require us to fund shortfalls, but allow for termination of the contract if specified operating performance levels are not achieved. However, in limited cases, we are obligated to fund performance shortfalls, creating variable interests in the ownership entities of the hotels, of which we are not the primary beneficiary. As of June 30, 2021, we had five performance guarantees, with expirations ranging from 2023 to 2039, and possible cash outlays totaling approximately $18 million. Our obligations under these guarantees in future periods are dependent on the operating performance level of the related hotel over the remaining term of the performance guarantee. We have included the impact of the COVID-19 pandemic on these hotels in our expectations of their future operating performance and, as of June 30, 2021 and December 31, 2020, we accrued current liabilities of $1 million and $7 million, respectively, for our performance guarantees. We may enter into new contracts containing performance guarantees in the future, which could increase our possible cash outlays. As of June 30, 2021, we guaranteed a $10 million loan, which matures in 2023, for two hotels that we will franchise. Additionally, we have an agreement with the owner of a hotel that we manage to finance capital expenditures at the hotel, contingent on certain criteria imposed on the owner. As of June 30, 2021, we had remaining possible cash outlays related to this agreement of approximately $10 million; however, we cannot currently estimate the timing of the payments or if they will be made at all, since we will not be obligated to fund such capital expenditures if certain terms of the agreement are not met. In June 2021, Hilton provided two letters of credit totaling $26 million to the owner of a hotel that we will manage to satisfy debt service reserve requirements for their debt with a third party. Each letter of credit will expire at the earlier of the date at which it is fully drawn or 2031. We receive fees from managed and franchised properties to operate our marketing, sales and brand programs on behalf of hotel owners, which are based on the underlying hotel's sales or usage. As a result of the adverse impact of the COVID-19 pandemic on our hotels' sales and, ultimately, the program fees we earn, our costs to operate these programs have outpaced the fees received, which, as of June 30, 2021, resulted in $88 million of amounts expended and recognized on behalf of these programs exceeding the amounts collected. As of December 31, 2020, we had collected and recognized an aggregate of $5 million in excess of amounts expended, across all programs.

Schedule of Stock Options Valuation Assumptions	The grant date fair value per share of the options granted during the six months ended June 30, 2021 was $41.15, which was determined using the Black-Scholes-Merton option-pricing model with the following assumptions: Expected volatility (1) 33.13 % Dividend yield (2) — % Risk-free rate (3) 0.92 % Expected term (in years) (4) 6.0 ____________ (1) Estimated using a blended approach of historical and implied volatility. Historical volatility is based on the historical movement of Hilton's stock price for a period that corresponds to the expected life of the option.

Earnings Per Share [Abstract]
Basic and Diluted Earnings (Loss) Per Share	The following table presents the calculation of basic and diluted earnings (loss) per share ("EPS"): Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 (in millions, except per share amounts) Basic EPS: Numerator: Net income (loss) attributable to Hilton stockholders $ 130 $ (430) $ 22 $ (412) Denominator: Weighted average shares outstanding 279 277 278 277 Basic EPS $ 0.47 $ (1.55) $ 0.08 $ (1.49) Diluted EPS: Numerator: Net income (loss) attributable to Hilton stockholders $ 130 $ (430) $ 22 $ (412) Denominator: Weighted average shares outstanding (1) 281 277 281 277 Diluted EPS (1) $ 0.46 $ (1.55) $ 0.08 $ (1.49) ____________ (1) Certain shares related to share-based compensation were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive under the treasury stock method, including less than 1 million shares for the three and six months ended June 30, 2021, and, as revised, 4 million and 3 million shares for the three and six months ended June 30, 2020, respectively. The dilutive shares related to share-based compensation included in the previously reported weighted average shares outstanding of 278 million and 279 million for the three and six months ended June 30, 2020, respectively, were revised in the current period presentation, as the previously reported dilutive shares were determined to be anti-dilutive as a result of the net loss attributable to Hilton stockholders reported during those periods. The result of the revision is an immaterial decrease in the previously reported diluted EPS for the six months ended June 30, 2020 of $0.01, with no change to the diluted EPS previously reported for the three months ended June 30, 2020.

[1]	Estimated using a blended approach of historical and implied volatility. Historical volatility is based on the historical movement of Hilton's stock price for a period that corresponds to the expected life of the option.
[2]	We have historically paid regular quarterly cash dividends. However, in March 2020, we suspended the declaration and payment of dividends as part of certain proactive measures we took to secure our liquidity position in response to the COVID-19 pandemic, and, at the time of the grant, we could not estimate when the payment of dividends would resume.
[3]	Based on the yields of U.S. Department of Treasury instruments with similar expected lives.
[4]	Estimated using the average of the vesting periods and the contractual term of the options.

[1]	Certain shares related to share-based compensation were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive under the treasury stock method, including less than 1 million shares for the three and six months ended June 30, 2021, and, as revised, 4 million and 3 million shares for the three and six months ended June 30, 2020, respectively. The dilutive shares related to share-based compensation included in the previously reported weighted average shares outstanding of 278 million and 279 million for the three and six months ended June 30, 2020, respectively, were revised in the current period presentation, as the previously reported dilutive shares were determined to be anti-dilutive as a result of the net loss attributable to Hilton stockholders reported during those periods. The result of the revision is an immaterial decrease in the previously reported diluted EPS for the six months ended June 30, 2020 of $0.01, with no change to the diluted EPS previously reported for the three months ended June 30, 2020.
