Accounting Policies [Abstract]
Significant Accounting Policies	2. Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023, which can be found in the Company’s Annual Report on Form 10-K. In management’s opinion, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the condensed consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited financial statements at that date but does not include all of the disclosures required by GAAP. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after elimination of all intercompany accounts and transactions. The condensed consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are necessary for the fair presentation of the Company’s results of operations and financial condition as of and for the periods presented. The results for the interim periods are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. There have been no significant changes to the Company’s significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 that have had a material impact on our condensed consolidated financial statements and related notes. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods covered by the financial statements and accompanying notes. These judgments, estimates, and assumptions are used for, but not limited to, (i) revenue recognition, including revenue-related reserves, (ii) stock-based compensation, (iii) valuation of the Company’s equity awards, (iv) legal and other loss contingencies, (v) income taxes, and (vi) capitalized internal-use software. The Company determines its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, actual results could differ from these estimates, and these differences may be material to the condensed consolidated financial statements. The Company has considered the impacts of macroeconomic trends affecting the Company’s markets and industry such as higher inflation, elevated interest rates, the effects of supply chain challenges, cessation of government aid programs, geopolitical conflicts, uncertainty regarding an economic recession and associated decreases in consumer discretionary income, changing consumer preferences, and the effects of severe weather patterns on the assumptions and inputs supporting certain of the Company’s estimates, assumptions, and judgments. The level of uncertainties and volatility in the global financial markets and economies, as well as the uncertainties related to these macroeconomic factors, geopolitical environment, and their effects on the Company’s operations and financial performance, means that these estimates may change in future periods as new events occur and additional information is obtained. Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures to enable investors to better understand an entity’s overall performance through enhanced disclosures about significant segment expenses. The guidance enhances interim disclosure requirements, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss, and provide new segment disclosure requirements for entities with a single reportable segment. This update is effective for all entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. An entity should apply the enhanced segment disclosure requirements retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as information on income taxes paid. The standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the impact that this guidance will have on its 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.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	9. Commitments and Contingencies Leases The Company’s leases primarily include corporate offices and warehouse space. The lease terms of operating leases vary from one year to 11 years, with expirations through January 2029. The Company has leases that include one or more options to extend the lease term for up to five years, as well as options to terminate the lease within one year. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. Most of these options to extend or terminate the lease do not create a significant economic incentive to extend the lease term and hence are not recognized as part of the Company’s operating lease liabilities and operating lease right-of-use assets. The Company did not modify, enter into, or acquire any material leasing arrangements during the three or nine months ended September 30, 2023 or 2024. Sales and Indirect Taxes The Company pays applicable state, franchise, and other taxes in state and local jurisdictions in which the Company conducts business. In the United States, the Company is under audit by various tax authorities with regard to sales and indirect tax matters. The subject matter of these audits primarily relates to the reporting of sales on behalf of the Company’s third-party sellers or tax treatment applied to the sale of the Company’s services in these jurisdictions. The Company believes it properly accrues and pays taxes according to its understanding of the tax requirements in each taxing jurisdiction; however it is possible that tax authorities may question the Company’s interpretation of taxability. As such, there is a high degree of complexity involved in the interpretation and application of state and local sales and indirect tax rules to the Company’s activities. As a result, the Company maintains a reserve related to potential tax, interest, or penalties that may become due . Significant judgments are made by the Company in estimating these reserves which includes assessing the taxability of goods or services transacted using the Company’s technology solution. The Company maintains such reserves until the respective statute of limitations has passed or upon conclusion of an audit examination with the relevant tax authorities, at which point the tax exposure and related interest and penalties are released. The reserve balance was $32 million and $27 million as of December 31, 2023 and September 30, 2024, respectively, and was included within other long-term liabilities on the condensed consolidated balance sheets. The Company recognized a reserve release of $23 million and $1 million related to these reserves for three months ended September 30, 2023 and 2024, respectively. The Company recognized a reserve release of $34 million and $4 million for the nine months ended September 30, 2023 and 2024 . The reserve release during the three and nine months ended September 30, 2023 is primarily due to a reserve release of $18 million related to the resolution of a sales and use tax examination with the State of New York. These amounts were recorded within general and administrative expense in the condensed consolidated statements of operations. Legal Matters The outcomes of the Company’s legal proceedings are inherently unpredictable and subject to significant uncertainties. The Company records a liability for legal contingencies when the Company believes that it is both probable that a loss has been incurred and the amount can be estimated. If the Company determines that a loss is reasonably possible and the loss or range of loss can be estimated, the Company discloses the possible loss in the condensed consolidated financial statements. If the Company determines that a loss is either probable or reasonably possible, but the loss or range of loss cannot be estimated, the Company discloses that fact in the condensed consolidated financial statements. Until the final resolution of legal matters, there may be an exposure to a material loss in excess of the amount recorded. Legal fees are expensed as incurred. Independent Contractor Classification Matters The Company operates in several jurisdictions where there have been regulations enacted with respect to methods companies should use to classify workers as either independent contractors or employees, such as California, which enacted California Assembly Bill 5 in 2019. The Company believes that it has properly classified its workers in all jurisdictions in which it operates. Further, on December 16, 2020, the California state ballot initiative, Proposition 22, which provides a framework that offers legal certainty regarding the status of independent workers offering delivery services in California and protects worker flexibility, the quality of on-demand work, and access to benefits for those who qualify, among other things, became effective. The Company provides appropriate worker benefits and other protections in accordance with Proposition 22, including guaranteed minimum earnings, healthcare subsidies, insurance, and safety trainings. Although the constitutionality of Proposition 22 was subsequently challenged, on July 25, 2024, the California Supreme Court upheld Proposition 22 as constitutional. However, there may continue to be legal challenges, or legislative or other attempts to amend or otherwise invalidate the benefits, protections, or the independent worker status provided by Proposition 22. Further, any future judgments, settlements, or orders issued by a court or governmental body or otherwise in connection with any judicial, administrative, or legal proceeding that results in the Company being prohibited from continuing to use independent-contractor shoppers in the manner it currently does would likely result in increases to its costs related to shoppers and decreases in the breadth of its offerings and geographic coverage. Further, if the Company changes its offerings or increases customer fees as a result of the increased costs, such changes may result in lower order volumes, which in turn would have an adverse effect on the Company’s business, financial condition, and results of operations. The Company has other active legal matters in California and several other jurisdictions, including litigation, government audits, administrative claims, and inquiries, related to its classification of individuals who provide delivery and other fulfillment services as non-employee contractors. These matters involve allegations that certain individuals are misclassified and, as a result, may be due unpaid minimum statutory wages, overtime, expense reimbursement, and certain other payments and protections, among other issues. Courts and agencies handling these matters may rule that the Company cannot engage workers to perform certain tasks, including delivery and other fulfillment services, as independent contractors. In some of these cases, the Company has entered into settlement agreements to resolve the claims without any admission of liability and in others, there is active litigation or proceedings. The Company is also involved in administrative audits with various state and local enforcement agencies, including audits related to shopper classification, state and local ordinance requirements, and unemployment insurance and workers’ compensation contributions, in Alaska, Florida, New Jersey, New York, Pennsylvania, and Washington. The Company believes that it complies with applicable legal requirements and that shoppers are properly classified as independent contractors; therefore, the Company disputes that it is obligated to provide such additional benefits under state law and plans to vigorously contest any adverse assessment or determination. The Company’s chances of success on the merits are still uncertain, such that any reasonably possible loss or range of loss cannot be estimated. However, the results of these audits may result in additional payments, including settlement payments, penalties, and interest, and such additional amounts could have a material impact on the Company’s business, financial conditions, results of operations, and cash flows. In March 2023, the Company entered into a settlement agreement with the California Employment Development Department to resolve disputes concerning alleged unemployment insurance contributions for $32 million. In April 2023, the settlement became effective after the approval by the California Attorney General and an Administrative Law Judge of the California Unemployment Insurance Appeal Board. This amount was previously accrued for and subsequently paid during the year ended December 31, 2023. The Company is also currently involved in several putative class and collective actions, thousands of alleged individual claims, including those brought or threatened to be brought in arbitration or compelled to arbitrate pursuant to its independent contractor agreements, and matters brought, in whole or in part, as representative actions under California’s Private Attorney General Act, Labor Code Section 2698, et seq., alleging that the Company misclassified shoppers as independent contractors and related claims. None of the putative class or collective actions have progressed to or resulted in class certification. Those involving misclassification have motions to compel individual arbitration pending in court. Securities Litigation On January 25, 2024, a purported shareholder filed suit against the Company and certain of the Company’s current and former officers and directors in the Northern District of California, on behalf of a putative class of purchasers of the Company’s common stock in its initial public offering (“IPO”) or between September 19, 2023 and October 1, 2023. The complaint alleges violations of Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 in connection with the Company’s IPO, and seeks damages and attorneys’ fees, among other things. An amended complaint also added the underwriters of our IPO as defendants. On October 29, 2024, we filed a motion to dismiss the amended complaint. At this time, the Company is unable to estimate any range of reasonably possible losses. Other Litigation Matters In addition to the matters described above, the Company and its subsidiaries are also routinely subject to actual or threatened legal actions relating to alleged violations of contract, regulatory, environmental, health and safety, employment, intellectual property, data protection and privacy, consumer protection, unfair competition, tax, and other laws and securities and shareholder claims. In some of these proceedings, claims for substantial monetary damages are asserted against the Company and could result in fines, penalties, compensatory damages, or non-monetary relief. The Company does not believe that these matters will have a material adverse effect upon its operations, cash flows, or financial condition. To the extent the Company has agreed to settle outstanding claims or where the Company has concluded it is probable that a resolution may be reached at an amount of loss that is estimable, the loss has been recognized within general and administrative expense in the condensed consolidated statements of operations. During periods where the settled amount is less than the loss reserved or if the Company estimates that an outstanding claim is less than that previously recorded, the Company will recognize a reserve release related to the claims within general and administrative expense in the condensed consolidated statements of operations. During the three months ended September 30, 2023 and 2024, the Company recognized immaterial reserve releases related to these claims. During the nine months ended September 30, 2023 and 2024 , the Company recognized a reserve release and a loss related to these claims of $6 million and $7 million, respectively. The actual losses incurred on claims that have not been resolved may differ from the initial estimates of loss, and such differences could be material. The Company is also subject from time to time to audits by government agencies in the various jurisdictions in which it operates. To the extent the Company is obligated to make payments in these jurisdictions (other than income taxes), the Company has recorded the related expense within general and administrative expense in the consolidated statements of operations. The results of these audits may result in additional payments, penalties, and interest, and such additional amounts could be material. Indemnifications The Company has entered into indemnification agreements with certain of the Company’s officers, directors, and current and former employees, and the Company’s certificate of incorporation and bylaws contain certain indemnification obligations. 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.

Equity [Abstract]
Redeemable Convertible Preferred Stock	10. Redeemable Convertible Preferred Stock Immediately subsequent to the closing of the IPO in September 2023, the Company authorized and issued 5,833,333 shares of Series A redeemable convertible preferred stock at a price of $30.00 per share for proceeds of $175 million. The Company determined the fair value of the Series A redeemable convertible preferred stock at issuance was $175 million and was determined using a Monte Carlo valuation model. The key assumptions used included the closing price of the Company’s common stock on the issuance date of $30.65, an expected term of approximately seven years, an expected volatility of 54%, and a discount for lack of marketability of 35%. Pursuant to the securities purchase agreement related to the issuance, the Company adopted the Certificate of Designation of Series A redeemable convertible preferred stock, as filed with the Secretary of State of the State of Delaware, setting forth the rights, designations, preferences, limitations, and restrictions applicable to the Series A redeemable convertible preferred stock. The rights, preferences, and privileges of the Series A redeemable convertible preferred stock are as follows: Seniority; Liquidation Preference The Series A redeemable convertible preferred stock, with respect to distribution rights upon the liquidation, winding-up or dissolution of the Company (but excluding a change of control, as described below ranks (i) senior to the Company’s common stock, (ii) on parity with any class or series of the Company’s capital stock expressly designated as ranking on parity with the Series A redeemable convertible preferred stock, and (iii) junior to any class or series of the Company’s capital stock expressly designated as ranking senior to the Series A redeemable convertible preferred stock. The Series A redeemable convertible preferred stock has a liquidation preference equal to the greater of (i) the Stated Value (as defined below), and (ii) the amount that the holder would be entitled to receive on an as-converted to common stock basis based on the then-applicable Conversion Ratio (as defined below), on the date of such liquidation, winding-up or dissolution. Such liquidation, winding-up or dissolution amounts would be paid out of the Company’s assets legally available for distribution to its stockholders, after satisfaction of debt and other liabilities owed to its creditors and holders of shares of any senior securities and before any payment or distribution is made to holders of any junior securities, including, without limitation, the Company’s common stock. The Stated Value for the Series A redeemable convertible preferred stock on a given date is defined as the sum of (i) the original issue price of the Series A redeemable convertible preferred stock, automatically increased at an annual rate of 5.0%, compounding on each anniversary of the issue date, through such date, and (ii) on an as-converted to common stock basis, the pro rata portion of any cash dividends or distributions that the Company pays on its common stock. The Conversion Ratio for the Series A redeemable convertible preferred stock means (i) a number of shares of common stock equal to the quotient of the Stated Value divided by the conversion price, plus (ii) if the product of such number of shares of common stock times the 10-Day VWAP (as defined below) is less than the Stated Value on such date, an additional number of shares of common stock that, when multiplied by the 10-Day VWAP, equals the difference. The 10-Day VWAP is defined as the average of the volume-weighted average price per share of common stock for each of the 10 consecutive trading days ending on, and including, the trading day immediately before the date of determination. Conversion From and after the seventh anniversary of the issue date of the Series A redeemable convertible preferred stock, at any time when the 10-Day VWAP exceeds the conversion price of the Series A redeemable convertible preferred stock, all outstanding shares of Series A redeemable convertible preferred stock will automatically convert into a number of shares of the Company’s common stock equal to the Conversion Ratio on such date. In addition, on the third anniversary of the issue date of the Series A redeemable convertible preferred stock, if the 10-Day VWAP immediately prior to such date exceeds the conversion price of the Series A redeemable convertible preferred stock, the holder will have the option to convert all outstanding shares of Series A redeemable convertible preferred stock at the conversion price on such date plus, if there is a Conversion Shortfall (as defined below), such additional number of shares of Common Stock that, when multiplied by the 10-Day VWAP immediately prior to such date, equals the Conversion Shortfall. The conversion price for the Series A redeemable convertible preferred stock is not subject to adjustment, except for customary adjustments for stock splits, stock dividends, recapitalizations, reorganizations and similar corporate actions. The Conversion Shortfall for the Series A redeemable convertible preferred stock on any conversion date is defined as the absolute dollar value by which the product of the Conversion Ratio and the 10-Day VWAP for an applicable conversion is less than the Stated Value plus the Minimum Return Amount on such date. Redemption At any time from and after the seventh anniversary of the issue date of the Series A redeemable convertible preferred stock, if the 10-Day VWAP does not exceed the conversion price, the Company has the right to redeem all, but not less than all, outstanding shares of Series A redeemable convertible preferred stock at the Stated Value on such redemption date. On each of the third anniversary (only if the 10-Day VWAP immediately prior to such date does not exceed the conversion price), the seventh anniversary, the tenth anniversary and the thirteenth anniversary of the issue date, the holder has the right to require the Company to redeem all, but not less than all, outstanding shares of Series A redeemable convertible preferred stock at the Stated Value on such redemption date. Upon a change of control of the Company, the Company will redeem all, but not less than all, outstanding shares of Series A redeemable convertible preferred stock for an amount equal to the greater of (i) the Stated Value on the date of the change of control and (ii) the amount that the holder would be entitled to receive on an as-converted to common stock basis based on the then-applicable conversion ratio (for which the 10-Day VWAP equals the purchase price or transaction consideration per share of common stock in the change of control transaction). Under certain regulatory events or strategic actions by the Company or the holder the Company or the holder, as applicable, has the right to elect to redeem all outstanding shares of Series A redeemable convertible preferred stock at the Stated Value, if the 10-Day VWAP immediately prior to the date of such event does not exceed the conversion price, or convert all outstanding shares of Series A redeemable convertible preferred stock into a number of shares of the Company’s common stock equal to the then-applicable conversion ratio, in case the 10-Day VWAP immediately prior to the date of such event exceeds the conversion price. The Company presents its Series A redeemable convertible preferred stock outside of stockholders’ equity as mezzanine equity because the shares contain redemption features that are not solely within the Company’s control. The Company is required to accrete the carrying value of the Series A redeemable preferred stock to its redemption value over the period from issuance through redemption date. The accretion was immaterial and $2 million during the three months ended September 30, 2023 and 2024, respectively. During the nine months ended September 30, 2023 and 2024, the accretion was immaterial and $7 million, respectively. Voting The Series A redeemable convertible preferred stock confers no voting rights on the holder, except as required by applicable law and with respect to matters that adversely change the powers, preferences, privileges, rights or restrictions of the Series A redeemable convertible preferred stock, including the authorization or issuance of equity securities that would rank senior to or pari passu with the Series A redeemable convertible preferred stock (other than, in certain cases, new shares of Series A redeemable convertible preferred stock or new series of preferred stock with substantially similar terms as the Series A redeemable convertible preferred stock) and the declaration or payment of cash dividends on shares other than the Series A redeemable convertible preferred stock in excess a 5.0% annual dividend yield. No dividends were declared or paid during the three or nine months ended September 30, 2023 or 2024.

In April 2024, the Company granted an aggregate of 586,920 RSUs to certain employees of the Company that vest upon satisfaction of certain performance-based and service-based vesting conditions. The performance-based vesting conditions will be satisfied based on the proportion of certain GTV targets achieved during applicable performance periods. The actual number of shares that may satisfy the performance-based vesting condition ranges from 0% to 100% of the maximum achievable shares for that performance period. Shares that satisfy the performance-based condition are subject to a service-based condition that vests quarterly over a period of one year following the applicable performance period. Each of the RSU awards granted is subject to potential vesting acceleration under certain circumstances. The weighted-average grant-date fair value per share of such awards is $36.35 and the weighted-average requisite service period is satisfied over a period of 2.70 years.

To meet the related tax withholding requirements for the net settlement, net exercise, and cancellation and repurchase, as applicable, of the vested RSUs, for certain vested stock options, and shares of vested restricted stock, the Company withheld or cancelled, as applicable, 20,810,882 of the 43,052,572 shares underlying such equity awards, resulting in the net issuance of 22,241,690 shares of common stock. Based on an IPO price of $30.00 per share, the Company’s tax withholding obligation was $570 million and was paid during the three months ended September 30, 2023.

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes The Company’s provision for income taxes for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items arising in that quarter. The Company’s effective tax rates for each period presented are the result of the mix of income earned in various tax jurisdictions that apply a broad range of income tax rates. The Company’s effective tax rate was 18.0% and 23.0% for the three months ended September 30, 2023 and 2024, respectively. The Company’s effective tax rate was 17.6% and 20.1% for the nine months ended September 30, 2023 and 2024, respectively. The Company’s provision for income taxes varied from the tax computed at the U.S. federal statutory income tax rate primarily due to tax effects of stock-based compensation recognized, U.S. research and development credits generated, and the income taxes generated in foreign jurisdictions.

Net Income per Share Attributable to Common Stockholders	13. Net Income per Share Attributable to Common Stockholders Prior to the IPO, the rights, including the liquidation and dividend rights, of the holders of voting and non-voting common stock were identical, except with respect to voting. As the liquidation and dividend rights were identical, the undistributed earnings were allocated on a proportionate basis and the resulting net income per share attributable to common stockholders were, therefore, the same for both voting and non-voting common stock on an individual or combined basis. The computation of basic and diluted net income per share attributable to common stockholders was as follows: Three Months Ended September 30, Nine Months Ended September 30, 2023 2024 2023 2024 (in millions, except share amounts, which are reflected in thousands, and per share amounts) Numerator: Net income $ (1,999) $ 118 $ (1,757) $ 309 Less: Accretion related to Series A redeemable convertible preferred stock — (2) — (7) Net income attributable to common stockholders, basic $ (1,999) $ 116 $ (1,757) $ 302 Add: Accretion related to Series A redeemable convertible preferred stock — 2 — — Net income attributable to common stockholders, diluted $ (1,999) $ 118 $ (1,757) $ 302 Denominator: Weighted-average shares used in computing basic net income per share attributable to common stockholders 95,836 259,660 80,180 266,550 Weighted-average effect of dilutive securities: Series A redeemable convertible preferred stock — 5,833 — — Stock options — 5,629 — 8,054 Restricted stock units — 9,881 — 11,097 Unvested restricted non-voting common stock — — — — Weighted-average shares used in computing diluted net income per share attributable to common stockholders 95,836 281,003 80,180 285,701 Net income per share attributable to common stockholders: Basic $ (20.86) $ 0.45 $ (21.92) $ 1.13 Diluted $ (20.86) $ 0.42 $ (21.92) $ 1.06 The following potentially dilutive outstanding securities were excluded from the computation of diluted income per share attributable to common stockholders because their effect was not dilutive: Three Months Ended September 30, Nine Months Ended September 30, 2023 2024 2023 2024 (in thousands) Series A redeemable convertible preferred stock 5,833 — 5,833 5,833 Stock options 19,996 384 19,996 428 Restricted stock units 28,559 5,811 28,559 2,470 Unvested restricted non-voting common stock 375 74 375 74 Total 54,763 6,269 54,763 8,805 The following potentially dilutive outstanding securities were excluded from the table above because they are subject to performance-based and / or market-based vesting conditions that were not achieved as of those dates: Three Months Ended September 30, Nine Months Ended September 30, 2023 2024 2023 2024 (in thousands) Restricted stock units 2,158 1,319 2,158 1,319 Total 2,158 1,319 2,158 1,319

The plan included the reduction of approximately 250 employees, or 7% of the Company’s employees. During the nine months ended September 30, 2024, the Company recognized $18 million in restructuring charges related to cash expenditures for severance payments and other termination benefits. No amounts were recognized during the three months ended September 30, 2024. During the three months ended March 31, 2024, the Company also recognized an immaterial amount of stock-based compensation expense related to the accelerated vesting of equity awards, which was offset by a $46 million benefit related to the reversal of previously recognized stock-based compensation expense for unvested equity awards for terminated employees in connection with the restructuring.

Subsequent Events	16. Subsequent Events In November 2024, the compensation committee of the Company’s board of directors modified the terms of an RSU award representing the right to be issued up to 1,200,000 shares of the Company’s common stock that was previously granted to the Company’s chief executive officer. In connection with the Company’s initial public offering in September 2023, 300,000 shares under the RSU award vested. The modification changed the existing market capitalization goals to corresponding stock price goals ranging from $43.32 per share to $86.64 per share. Achievement of the stock price goals is measured using the volume-weighted average closing price (“VWAP”) of the Company’s common stock over the 30-trading day period preceding the applicable measurement date. Following the modification of the RSU award, and based on the VWAP as of November 12, 2024, the stock price goal of $43.32 was met, resulting in the vesting of an additional 180,000 shares of the Company’s common stock under the RSU award.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2023, which can be found in the Company’s Annual Report on Form 10-K. In management’s opinion, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the condensed consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2023 has been derived from the audited financial statements at that date but does not include all of the disclosures required by GAAP. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries after elimination of all intercompany accounts and transactions. The condensed consolidated financial statements reflect all adjustments and reclassifications that, in the opinion of management, are necessary for the fair presentation of the Company’s results of operations and financial condition as of and for the periods presented. The results for the interim periods are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period. There have been no significant changes to the Company’s significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 that have had a material impact on our condensed consolidated financial statements and related notes.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates, and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods covered by the financial statements and accompanying notes. These judgments, estimates, and assumptions are used for, but not limited to, (i) revenue recognition, including revenue-related reserves, (ii) stock-based compensation, (iii) valuation of the Company’s equity awards, (iv) legal and other loss contingencies, (v) income taxes, and (vi) capitalized internal-use software. The Company determines its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. However, actual results could differ from these estimates, and these differences may be material to the condensed consolidated financial statements. The Company has considered the impacts of macroeconomic trends affecting the Company’s markets and industry such as higher inflation, elevated interest rates, the effects of supply chain challenges, cessation of government aid programs, geopolitical conflicts, uncertainty regarding an economic recession and associated decreases in consumer discretionary income, changing consumer preferences, and the effects of severe weather patterns on the assumptions and inputs supporting certain of the Company’s estimates, assumptions, and judgments. The level of uncertainties and volatility in the global financial markets and economies, as well as the uncertainties related to these macroeconomic factors, geopolitical environment, and their effects on the Company’s operations and financial performance, means that these estimates may change in future periods as new events occur and additional information is obtained.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures to enable investors to better understand an entity’s overall performance through enhanced disclosures about significant segment expenses. The guidance enhances interim disclosure requirements, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss, and provide new segment disclosure requirements for entities with a single reportable segment. This update is effective for all entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. An entity should apply the enhanced segment disclosure requirements retrospectively to all prior periods presented in the financial statements. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which requires disaggregated information about a reporting entity’s effective tax rate reconciliation, as well as information on income taxes paid. The standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The guidance will be applied on a prospective basis with the option to apply the standard retrospectively. The Company is currently evaluating the impact that this guidance will have on its 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.
