Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Organization Arista Networks, Inc. (together with our subsidiaries, “we,” “our,” "Arista," "Company" or “us”) is a supplier of cloud networking solutions that use software innovations to address the needs of next generation data center, campus and routing environments. Our cloud networking solutions consist of our Extensible Operating System ("EOS"), a set of network applications and our Ethernet switching and routing platforms. We are incorporated in the state of Delaware. Our corporate headquarters are located in Santa Clara, California, and we have wholly-owned subsidiaries throughout the world, including North America, Europe, Asia and Australia. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Arista Networks, Inc. and its wholly-owned subsidiaries and have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted. In management’s opinion, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three and nine months ended September 30, 2024, are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by GAAP for complete financial statements. All significant inter-company accounts and transactions have been eliminated. Our condensed consolidated financial statements and related financial information in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and related footnotes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on February 12, 2024. Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Those estimates and assumptions include, but are not limited to, valuation of inventory and contract manufacturer/supplier liabilities, accounting for income taxes, including the recognition of deferred tax assets and liabilities, valuation allowance on deferred tax assets and reserves for uncertain tax positions, revenue recognition and deferred revenue, valuation of goodwill and acquisition-related intangible assets, estimate of useful lives of long-lived assets including intangible assets, and the recognition and measurement of contingent liabilities. We evaluate our estimates and assumptions based on historical experience and other factors and adjust these estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates. Risks and Uncertainties Global economic and business activities continue to face widespread macroeconomic uncertainties, including the effects of, among other things, inflation, monetary policy shifts, recession risks, potential supply chain disruptions, and geopolitical pressures. Our business is emerging from a period of unprecedented global supply chain disruptions. Throughout this period, we made significant supply chain investments, including funding additional working capital and incremental purchase commitments in response to extended visibility to deployment plans from our customers. We have worked closely with our contract manufacturers and supply chain partners to ramp production following a period of delayed component sourcing and workforce disruptions. Increased capacity has allowed us to ship products against previously committed demand/deployment plans and accelerate some deployments where needed, while trying to minimize building customer inventory, and to some extent balancing customer lead times with those currently experienced from our key suppliers. As a result, some shipments against these previously committed demand/deployment plans have extended into 2024. As the global supply chain has experienced some improvements and as customer lead times have been reduced from their peak, we have seen and expect to continue to see a commensurate reduction in visibility to customer demand and a gradual return to shorter demand-planning horizons. Given these shipment and order patterns, near term revenue trends may not be solely reflective of current demand levels, but as discussed above will benefit from demand/deployment plans that had been previously committed. We expect that our inventory and purchase commitments will remain volatile as we ramp new product introductions. The magnitude of these balances, combined with a reduction in customer demand-planning horizons and shifting customer product priorities, has resulted in increased risk that we may not be able to sell all of this inventory, which in turn has resulted in additional excess and obsolete inventory and supplier liability charges. In addition, inflation pressure in our supply chain and scarcity of some materials needed to build our products have increased our cost of revenue and have impacted, and may continue to negatively impact our gross margin. While we have seen improvements in our supply chain and manufacturing operations, any remaining or new supply chain and manufacturing related constraints could negatively impact our business in future periods. Management continues to actively monitor the impact of macroeconomic factors on the Company's financial condition, liquidity, operations, suppliers, industry, and workforce. The extent of the impact of these factors on our operational and financial performance, including our ability to execute our business strategies and initiatives in the expected time frame, will depend on future developments, the impact on our customers, partners, employees, contract manufacturers and supply chain, all of which continue to evolve and are unpredictable. In addition, any continued or renewed disruption in manufacturing and supply resulting from these factors could negatively impact our business. Recent technologies, such as generative AI models, have emerged, and while they have driven increased demand for networking, the long-term trajectory is unknown. As such, demand estimates for our new products may be inaccurate and create volatility in our revenue and inventory levels. Furthermore, any prolonged economic disruptions or further deterioration in the global economy could have a negative impact on demand from our customers in future periods, particularly in the enterprise market where we are continuing to expand our penetration. Accordingly, current results and financial conditions discussed herein may not be indicative of future operating results and trends. Recent Accounting Pronouncements Not Yet Effective In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740)-Improvements to Income Tax Disclosures. The ASU requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, the ASU requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued. The amendments should be applied on a prospective basis although retrospective application is permitted. As of September 30, 2024 , we have not early adopted ASU 2023-09 and we are currently evaluating the impact of future adoption on our financial disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280)-Improvements to Reportable Segment Disclosures. The ASU requires that an entity disclose significant segment expenses impacting profit and loss that are regularly provided to the chief operating decision maker. The update is required to be applied retrospectively to prior periods presented, based on the significant segment expense categories identified and disclosed in the period of adoption. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. As of September 30, 2024, we have not early adopted ASU 2023-07 and we are currently evaluating the impact of future adoption on our financial disclosures.

We invest in debt securities that have maximum maturities of two years and are generally deemed to be low risk based on their credit ratings from the major rating agencies. The longer the duration of these marketable securities, the more susceptible they are to changes in market interest rates and bond yields. Given the short-term and conservative nature of our portfolio, our debt securities are generally not subject to credit risk; therefore, we did not recognize any credit losses or non-credit-related impairments related to such securities for the three and nine months ended September 30, 2024. All unrealized losses were recognized in other comprehensive income (loss). Realized gains or losses were immaterial for the three and nine months ended September 30, 2024.

As we view these marketable securities as available to support current operations, we classify marketable securities with maturities beyond 12 months as current assets under the caption "Marketable securities" on the condensed consolidated balance sheets. Assets measured at fair value on a non-recurring basis Non-Marketable Equity Securities We have non-marketable equity securities in privately-held companies that do not have readily-determinable fair values. These equity securities are included in Other Assets on the condensed consolidated balance sheets. Their initial cost is adjusted to fair value on a non-recurring basis based on observable price changes from orderly transactions of identical or similar securities of the same issuer, or for impairment. These investments are classified within Level III of the fair value hierarchy as we estimate the value based on valuation methods using the observable transaction price at the transaction date and other significant unobservable inputs, such as volatility, rights, and obligations related to these securities. In addition, the valuation requires management judgment due to the absence of market price and lack of liquidity. We did not record any realized gains or losses on our non-marketable equity securities during the three and nine months ended September 30, 2024 and September 30, 2023, and w e recorded immaterial amounts of unrealized gains or losses for the three and nine months ended September 30, 2024 and September 30, 2023, respectively . We evaluate our non-marketable equity securities for impairment at each reporting period via a qualitative assessment with various potential impairment indicators, including, but not limited to, an assessment of a significant adverse change in the economic environment, significant adverse changes in the general market condition of the geographies and industries in which our investees operate, and other publicly-available information that affected the value of the non-marketable equity securities . The following table summarizes the activity related to our non-marketable equity securities as of September 30, 2024 and December 31, 2023 (in thousands): September 30, 2024 December 31, 2023 Cost of investments $ 38,284 $ 31,656 Cumulative impairment and downward adjustment — — Cumulative upward adjustment 43,032 30,632 Carrying amount of investments $ 81,316 $ 62,288

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases We have operating lease arrangements for office space, data center, equipment and other corporate assets. As of September 30, 2024, we had lease payment obligations, net of immaterial sublease income, of $69.8 million, with $24.1 million payable within one year. Purchase Commitments We outsource most o f our manufacturing and supply chain management operations to third-party contract manufacturers, who procure components and assemble products on our behalf. A significant portion of our purchase orders to our contract manufacturers for finished products consists of non-cancellable purchase commitments. In addition, we purchase strategic component inventory from certain suppliers under non-cancellable purchase commitments, including integrated circuits, which are consigned to our contract manufacturers. As of September 30, 2024, we had non-cancellable purchase commitments not recorded on our balance sheet of $2.4 billion, of which $2.0 billion have expected receipt dates within 12 months, and $0.4 billion have expected receipt dates greater than 12 months. These open purchase orders are considered enforceable and legally binding, and while we may have some limited ability to reschedule, and adjust our requirements based on our business needs prior to the delivery of goods or performance of services, this can only occur with the agreement of the related supplier. We also had deposits to our contract manufacturers to secure our purchase commitments in the amount of $116.5 million and $133.3 million as of September 30, 2024 and December 31, 2023, respectively, which were recorded within prepaid expenses and other current assets, as well as other assets in the condensed consolidated balance sheets. Guarantees We have entered into agreements with some of our direct customers and channel partners that contain indemnification provisions relating to potential situations where claims could be alleged that our products infringe the intellectual property rights of a third party. We have, at our option and expense, the ability to repair any infringement, replace product with a non-infringing equivalent-in-function product or refund our customers all or a portion of the value of the product. Other guarantees or indemnification agreements include guarantees of product and service performance and standby letters of credit for leased facilities and corporate credit cards. We have not recorded a liability related to these indemnification and guarantee provisions and our guarantee and indemnification arrangements have not had a significant impact on our consolidated financial statements to date. Legal Proceedings WSOU Investments, LLC On November 25, 2020, WSOU Investments LLC ("WSOU") filed a lawsuit against us in the Western District of Texas asserting that certain of our products infringe three WSOU patents. WSOU's allegations are directed to certain features of our wireless and switching products. WSOU seeks remedies including monetary damages, attorney's fees and costs. On February 4, 2021, we filed an answer denying WSOU's allegations. On November 5, 2021, the case was transferred to the Northern District of California. On March 30, 2022, WSOU dismissed one of the patents with prejudice, removing Arista wireless products from those accused of infringement. On July 1, 2022, the court stayed the case pending the resolution of an inter partes review of one of the patents-in-suit. On May 30, 2023, the US Patent Trial and Appeal Board (“PTAB”) ruled all challenged claims in the inter partes review unpatentable. The district court case remains stayed pending appeal and/or final resolution of the PTAB ruling. We intend to vigorously defend against the claims brought against us by WSOU; however, we cannot be certain that any of WSOU's claims will be resolved in our favor, regardless of the merits of those claims. Any adverse litigation ruling could result in a significant damages award against us and injunctive relief. With respect to the legal proceedings described above, it is our belief that while a loss is not probable, it may be reasonably possible. Further, at this stage in the litigation, any possible loss or range of loss cannot be estimated; however, the outcome of litigation is inherently uncertain. Therefore, if this legal matter were resolved against us in a reporting period for a material amount, our consolidated financial statements for that reporting period could be materially adversely affected. Other matters In the ordinary course of business, we are a party to other claims and legal proceedings including matters relating to commercial, employee relations, business practices and intellectual property. We record a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. As of September 30, 2024, provisions recorded for contingent losses related to other claims and matters have not been significant. Based on currently-available information, management does not believe that any additional liabilities relating to other unresolved matters are probable or that the amount of any resulting loss is estimable, and believes these other matters are not likely, individually and in the aggregate, to have a material adverse effect on our financial position, results of operations or cash flows; however, litigation is subject to inherent uncertainties and our view of these matters may change in the future. Were an unfavorable outcome to occur, there exists the possibility of a material adverse impact on our financial position, results of operations or cash flows for the period in which the unfavorable outcome occurs, and potentially in future periods.

Share-Based Payment Arrangement [Abstract]
Stockholders’ Equity and Stock-Based Compensation	Stockholders’ Equity and Stock-Based Compensation Stock Repurchase Program In April 2024, we completed repurchases under our previous $1.0 billion stock repurchase program (the “Prior Repurchase Program”). In May 2024, our board of directors authorized a new $1.2 billion stock repurchase program (the “New Repurchase Program” and together with the Prior Repurchase Program, the "Repurchase Programs"), which commenced in May 2024 and expires in May 2027. This authorization allows us to repurchase shares of our common stock that will be funded from working capital. Repurchases may be made at management's discretion from time to time on the open market, through privately negotiated transactions, transactions structured through investment banking institutions, block purchases, trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or a combination of the foregoing. The Repurchase Programs do not obligate us to acquire any of our common stock, and may be suspended or discontinued by the company at any time without prior notice. During the three months ended September 30, 2024 , we repurchase d a total of $65.2 million of our common stock under our New Repurchase Program. D uring the nine months ended September 30, 2024 , we repurchase d a total of $155.2 million of our common stock under our New Repurchase Program and $144.6 million of our common stock under our Prior Repurchase Program. As of September 30, 2024, the remaining authorized amount for stock repurchases under the New Repurchase Program was approximately $1.0 billion. A summary of the stock repurchase activity for the three and nine months ended September 30, 2024 is as follows (in thousands, except per share amounts): Three Months Ended Nine Months Ended September 30, 2024 September 30, 2024 Aggregate purchase price $ 65,157 $ 299,823 Shares repurchased 205 1,047 Average price paid per share $ 318.14 $ 286.47 The aggregate purchase price of repurchased shares of our common stock is recorded as a reduction to retained earnings in our unaudited condensed consolidated statements of stockholders' equity. All shares repurchased have been retired. Equity Award Plan Activities 2014 Equity Incentive Plan On April 16, 2024, our board of directors adopted an amended and restated Arista Networks, Inc. 2014 Equity Plan (the "Restated Plan"), effective April 17, 2024 (the "Effective Date") subject to the approval of our stockholders, which wa s approved at the 2024 Annual Meeting of Stockholders on June 7, 2024. The Restated Plan provides for the grant of equity-based awards, including stock options, restricted stock units, restricted stock, stock appreciation rights, and performance awards. The share pool available under the prior version of the Company's 2014 Equity Incentive Plan (the "Prior Plan") was extinguished, and the Restated Plan provides for a new share pool not to exceed (i) 13,200,000 shares of our Common Stock (“Shares”), plus (ii) any Shares subject to awards under the Prior Plan that, on or after the Effective Date, expired or otherwise terminated without having been exercised in full, or that were forfeited to or repurchased by us, including net settlement of Shares subject to restricted stock units, with the maximum number of Shares to be added to the Restated Plan as a result of clause (ii) equal to 10,039,657 Shares. The Restated Plan’s terms are substantially similar to the Prior Plan’s terms, including with respect to treatment of equity awards in the event of a “change in control” as defined under the Restated Plan, but with certain modifications, including the elimination of the automatic “evergreen” share reserve increase provided for under the Prior Plan. As of September 30, 2024, there remained approximately 13.1 million shares available for grant under the Restated Plan. 2014 Employee Stock Purchase Plan In April 2014, our board of directors and stockholders approved the 2014 Employee Stock Purchase Plan (the “ESPP”). The ESPP became effective on the first day that our common stock was publicly traded. The number of shares reserved for issuance under the ESPP increases automatically on January 1 of each year by the number of shares equal to 1% of our shares outstanding on the immediately preceding December 31, but not to exceed 10 million shares, unless our board of directors, in its discretion, determines to make a smaller increase. Effective January 1, 2024, our board of directors authorized an increase of 3.1 million shares to the shares available for issuance under the ESPP. During the nine months ended September 30, 2024, we issued 280,843 shares at a weighted-average purchase price of $116.31 per share under the ESPP. As of September 30, 2024, there remained approximately 26.2 million shares available for issuance under the ESPP.

Subsequent Events [Abstract]
Subsequent event	Subsequent event Arista’s board of directors has approved a four-for-one forward stock split to make Arista’s common stock more accessible to a broader base of investors. The four-for-one forward stock split will be effected through the filing of an amendment to Arista’s Amended and Restated Certificate of Incorporation that will proportionately increase the authorized shares of common stock. Our stockholders will receive an additional three shares of common stock for each share held as of the effective time of the filing of the amendment on December 3, 2024. Prior to market open on December 4, 2024, trading is expected to commence on a split-adjusted basis. The following table reflects basic and diluted weighted average shares and net income per share on an unaudited pro forma basis giving effect to the stock split as if it had been effective for all periods presented (in thousands, except per share amounts).

Organization and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Arista Networks, Inc. and its wholly-owned subsidiaries and have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted. In management’s opinion, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three and nine months ended September 30, 2024, are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by GAAP for complete financial statements. All significant inter-company accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Those estimates and assumptions include, but are not limited to, valuation of inventory and contract manufacturer/supplier liabilities, accounting for income taxes, including the recognition of deferred tax assets and liabilities, valuation allowance on deferred tax assets and reserves for uncertain tax positions, revenue recognition and deferred revenue, valuation of goodwill and acquisition-related intangible assets, estimate of useful lives of long-lived assets including intangible assets, and the recognition and measurement of contingent liabilities. We evaluate our estimates and assumptions based on historical experience and other factors and adjust these estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates.
Risks and Uncertainties	Risks and Uncertainties Global economic and business activities continue to face widespread macroeconomic uncertainties, including the effects of, among other things, inflation, monetary policy shifts, recession risks, potential supply chain disruptions, and geopolitical pressures. Our business is emerging from a period of unprecedented global supply chain disruptions. Throughout this period, we made significant supply chain investments, including funding additional working capital and incremental purchase commitments in response to extended visibility to deployment plans from our customers. We have worked closely with our contract manufacturers and supply chain partners to ramp production following a period of delayed component sourcing and workforce disruptions. Increased capacity has allowed us to ship products against previously committed demand/deployment plans and accelerate some deployments where needed, while trying to minimize building customer inventory, and to some extent balancing customer lead times with those currently experienced from our key suppliers. As a result, some shipments against these previously committed demand/deployment plans have extended into 2024. As the global supply chain has experienced some improvements and as customer lead times have been reduced from their peak, we have seen and expect to continue to see a commensurate reduction in visibility to customer demand and a gradual return to shorter demand-planning horizons. Given these shipment and order patterns, near term revenue trends may not be solely reflective of current demand levels, but as discussed above will benefit from demand/deployment plans that had been previously committed. We expect that our inventory and purchase commitments will remain volatile as we ramp new product introductions. The magnitude of these balances, combined with a reduction in customer demand-planning horizons and shifting customer product priorities, has resulted in increased risk that we may not be able to sell all of this inventory, which in turn has resulted in additional excess and obsolete inventory and supplier liability charges. In addition, inflation pressure in our supply chain and scarcity of some materials needed to build our products have increased our cost of revenue and have impacted, and may continue to negatively impact our gross margin. While we have seen improvements in our supply chain and manufacturing operations, any remaining or new supply chain and manufacturing related constraints could negatively impact our business in future periods. Management continues to actively monitor the impact of macroeconomic factors on the Company's financial condition, liquidity, operations, suppliers, industry, and workforce. The extent of the impact of these factors on our operational and financial performance, including our ability to execute our business strategies and initiatives in the expected time frame, will depend on future developments, the impact on our customers, partners, employees, contract manufacturers and supply chain, all of which continue to evolve and are unpredictable. In addition, any continued or renewed disruption in manufacturing and supply resulting from these factors could negatively impact our business. Recent technologies, such as generative AI models, have emerged, and while they have driven increased demand for networking, the long-term trajectory is unknown. As such, demand estimates for our new products may be inaccurate and create volatility in our revenue and inventory levels. Furthermore, any prolonged economic disruptions or further deterioration in the global economy could have a negative impact on demand from our customers in future periods, particularly in the enterprise market where we are continuing to expand our penetration. Accordingly, current results and financial conditions discussed herein may not be indicative of future operating results and trends.
Recent Accounting Pronouncements Not Yet Effective	Recent Accounting Pronouncements Not Yet Effective In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740)-Improvements to Income Tax Disclosures. The ASU requires that an entity disclose specific categories in the effective tax rate reconciliation as well as provide additional information for reconciling items that meet a quantitative threshold. Further, the ASU requires certain disclosures of state versus federal income tax expense and taxes paid. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued. The amendments should be applied on a prospective basis although retrospective application is permitted. As of September 30, 2024 , we have not early adopted ASU 2023-09 and we are currently evaluating the impact of future adoption on our financial disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280)-Improvements to Reportable Segment Disclosures. The ASU requires that an entity disclose significant segment expenses impacting profit and loss that are regularly provided to the chief operating decision maker. The update is required to be applied retrospectively to prior periods presented, based on the significant segment expense categories identified and disclosed in the period of adoption. The amendments in this ASU are required to be adopted for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. As of September 30, 2024, we have not early adopted ASU 2023-07 and we are currently evaluating the impact of future adoption on our financial disclosures.
