The Company and Summary of Sign

The Company and Summary of Significant Accounting Policies	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Summary of Significant Accounting Policies	The Company and Summary of Significant Accounting Policies The Company eBay Inc. is a global commerce leader that connects people and builds communities to create economic opportunity for all. Our technology empowers millions of buyers and sellers in more than 190 markets around the world, providing everyone the opportunity to grow and thrive. Our Marketplace platforms, including our online marketplace located at www.ebay.com and its localized counterparts, our off-platform businesses in Japan and the United States, and our suite of mobile apps, together, create one of the world's largest and most vibrant marketplaces for discovering great value and unique selection. When we refer to “we,” “our,” “us,” the “Company” or “eBay” in this Quarterly Report on Form 10-Q, we mean the current Delaware corporation (eBay Inc.) and its consolidated subsidiaries, unless otherwise expressly stated or the context otherwise requires. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including but not limited to those related to provisions for transaction losses, legal contingencies, income taxes, revenue recognition, stock-based compensation, investments including level 3 investments in Gmarket Global LLC (“Gmarket”), warrants and the recoverability of goodwill and intangible assets. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from those estimates. We review the useful lives of equipment on an ongoing basis, and effective January 1, 2024 we changed our estimate of the useful lives for our servers and networking equipment from three years to four years. The longer useful lives are due to continuous improvements in our hardware, software, and data center designs. The effect of this change in estimate for the three months ended June 30, 2024, based on servers and network equipment that were included in “Property and equipment, net” as of December 31, 2023 and those acquired during the six months ended June 30, 2024, was a reduction in depreciation expense of $17 million and an increase to net income of $12 million, or $0.02 per basic share and $0.02 per diluted share. The effect of this change in estimate for the six months ended June 30, 2024, based on servers and network equipment that were included in “Property and equipment, net” as of December 31, 2023 and those acquired during the six months ended June 30, 2024, was a reduction in depreciation expense of $43 million and an increase to net income of $34 million, or $0.07 per basic share and $0.07 per diluted share. Principles of Consolidation and Basis of Presentation The accompanying financial statements are consolidated and include the financial statements of eBay Inc. and our wholly and majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Minority interests are recorded as a noncontrolling interest. A qualitative approach is applied to assess the consolidation requirement for variable interest entities. Generally, investments in entities where we hold at least a 20% ownership interest and have the ability to exercise significant influence, but not control, over the investee are accounted for using the equity method of accounting, including those in which the fair value option has been elected. For equity method investments, our share of the investees’ results of operations is included in interest income and other, net and investment balances are included in long-term investments. For equity method investments under the fair value option, the change in fair value of the investment is included in loss on equity investments and warrant, net and investment balances are included in long-term investments, other than our equity interest in Adevinta ASA (“Adevinta”), which was included in the short-term assets section on the condensed consolidated balance sheet as of December 31, 2023 as discussed in “Note 5 — Investments.” Investments in entities where we hold less than a 20% ownership interest are generally accounted for as equity investments to be measured at fair value, under an election, or at cost if it does not have readily determinable fair value, in which case the carrying value would be adjusted upon the occurrence of an observable price change in an orderly transaction for identical or similar instruments or impairment. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”). We have evaluated all subsequent events through the date these condensed consolidated financial statements were issued. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods. Effective January 1, 2024, certain immaterial prior period balances have been reclassified to conform to the current period presentation in the condensed consolidated financial statements and the accompanying notes. Specifically, immaterial restricted cash balances previously reported as components of short-term and long-term investments are now reported within the other current assets and other assets sections, respectively, in our condensed consolidated balance sheet. Significant Accounting Policies The re were no significant changes to our significant accounting policies disclosed in “Note 1 — The Company and Summary of Significant Accounting Policies” in our 2023 Form 10-K , except customer accounts and funds receivable and cash, cash equivalents and restricted cash resulting from a change in our approach to safeguarding customer funds beginning in the first quarter of 2024, as noted below. Customer accounts and funds receivable Customer accounts represent cash received from buyers that is held by financial institutions. Due to safeguarding requirements in certain regions, a portion of this balance is considered restricted. Funds receivable represents customer cash in transit and held by payment processors. These balances are associated with marketplace activity and are awaiting payment to sellers. We are exposed to credit losses from customer accounts and funds receivable balances held by third party financial institutions and payment processors. We assess these balances for credit loss based on a review of the average period for which the funds are held, current credit ratings and our assessment of the probability of default and loss given default models. In the first six months of 2024 and 2023, no credit-related losses were recorded. Cash, cash equivalents and restricted cash Cash and cash equivalents are short-term, highly liquid investments with original maturities of three months or less when purchased, which may include bank deposits, U.S. Treasury securities, time deposits, and certificates of deposit. We consider cash to be restricted when withdrawal or general use is legally restricted. Restricted cash is held in interest bearing accounts for letters of credit related to our global sabbatical program and for certain amounts related to other compensation arrangements held in escrow. We also hold restricted cash in segregated bank accounts for purposes of safeguarding customer funds. Recent Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07—Segment Reporting (Topic 280): Improvements to Reportable Segments Disclosures. The new guidance is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses enabling investors to better understand an entity’s overall performance and assess potential future cash flows. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The standard will be effective for annual reporting periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-08—Intangibles—Goodwill and Other—Crypto Assets (Subtopic 350-60): Accounting for and Disclosure of Crypto Assets. The new guidance addresses the accounting and disclosure requirements for certain crypto assets and requires entities to subsequently measure certain crypto assets at fair value, with changes in fair value recorded in net income in each reporting period. In addition, entities are required to provide additional disclosures about the holdings of certain crypto assets. The standard is effective for annual reporting periods beginning after December 15, 2024, including interim reporting periods within those fiscal years. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The new guidance is intended to further standardize income tax disclosures primarily related to the presentation of the effective tax rate reconciliation and income taxes paid information in our financial statements and disclosures. The standard is effective for annual reporting periods beginning after December 15, 2024. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.

Net Income Per Share

Earnings Per Share [Abstract]
Net Income (Loss) Per Share	Net Income Per Share Basic net income per share is computed by dividing net income for the period by the weighted average number of shares of common stock outstanding during the period. Diluted net income per share is computed by dividing net income for the period by the weighted average number of shares of common stock and potentially dilutive common stock outstanding during the period. The dilutive effect of outstanding options and equity incentive awards is reflected in diluted net income per share by application of the treasury stock method. The calculation of diluted net income per share excludes all anti-dilutive shares of common stock. The following table presents the computation of basic and diluted net income per share for the periods indicated (in millions, except per share amounts): Three Months Ended Six Months Ended 2024 2023 2024 2023 Numerator: Income from continuing operations $ 226 $ 172 $ 665 $ 741 Loss from discontinued operations, net of income taxes (2) (1) (3) (3) Net income $ 224 $ 171 $ 662 $ 738 Denominator: Weighted average shares of common stock - basic 503 534 509 536 Dilutive effect of equity incentive awards 4 3 4 3 Weighted average shares of common stock - diluted 507 537 513 539 Income per share - basic: Continuing operations $ 0.45 $ 0.32 $ 1.31 $ 1.38 Discontinued operations — — (0.01) (0.01) Net income per share - basic $ 0.45 $ 0.32 $ 1.30 $ 1.37 Income per share - diluted: Continuing operations $ 0.45 $ 0.32 $ 1.30 $ 1.37 Discontinued operations — — (0.01) (0.01) Net income per share - diluted $ 0.45 $ 0.32 $ 1.29 $ 1.36 Common stock equivalents excluded from income per diluted share because their effect would have been anti-dilutive 13 12 15 12

Investments [Abstract]
Investments	Investments The following tables summarize the unrealized gains and losses and estimated fair value of our investments classified as available-for-sale debt securities as of the dates indicated (in millions): June 30, 2024 Gross Gross Gross Estimated Short-term investments: Corporate debt securities $ 2,755 $ — $ (6) $ 2,749 Government and agency securities 463 — (9) 454 $ 3,218 $ — $ (15) $ 3,203 Long-term investments: Corporate debt securities $ 774 $ 1 $ (5) $ 770 Government and agency securities 421 — (12) 409 $ 1,195 $ 1 $ (17) $ 1,179 December 31, 2023 Gross Gross Gross Estimated Short-term investments: Corporate debt securities $ 2,170 $ — $ (8) $ 2,162 Government and agency securities 382 — (11) 371 $ 2,552 $ — $ (19) $ 2,533 Long-term investments: Corporate debt securities $ 338 $ — $ (10) $ 328 Government and agency securities 287 — (16) 271 $ 625 $ — $ (26) $ 599 Our fixed-income investments consist of predominantly investment grade corporate debt securities and government and agency securities. The corporate debt and government and agency securities that we invest in are generally deemed to be low risk based on their credit ratings from major rating agencies. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As interest rates increase, securities purchased at a lower yield show a mark-to-market unrealized loss. The unrealized losses are primarily due to changes in credit spreads and interest rates. We regularly review investment securities for other-than-temporary impairment using both qualitative and quantitative criteria. Investments classified as available-for-sale debt securities are carried at fair value with changes reflected in other comprehensive income. Where there is an intention or a requirement to sell an impaired available-for-sale debt security, the entire impairment is recognized in earnings with a corresponding adjustment to the amortized cost basis of the security. From time to time, we sell available-for-sale debt securities in an unrealized loss position and recognize an immaterial loss. We regularly review investment securities for credit impairment using both qualitative and quantitative criteria. In making this assessment, we consider the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses will be recorded through interest income and other, net for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. We did not recognize any credit-related impairment through an allowance for credit losses as of June 30, 2024. Investment securities in a continuous loss position for less than 12 months had an estimated fair value of $3.6 billion and unrealized losses of $5 million as of June 30, 2024 compared to an estimated fair value of $1.5 billion and unrealized losses of $2 million as of December 31, 2023. Investment securities in a continuous loss position for greater than 12 months had an estimated fair value of $888 million and unrealized losses of $27 million as of June 30, 2024 compared to an estimated fair value of $1.1 billion and unrealized losses of $43 million as of December 31, 2023. Refer to “Note 14 — Accumulated Other Comprehensive Income” for amounts reclassified to earnings from unrealized gains and losses. The following table presents estimated fair values of our short-term and long-term investments classified as available-for-sale debt securities by date of contractual maturity as of the date indicated (in millions): June 30, One year or less $ 3,203 One year through two years 491 Two years through three years 672 Three years through four years 12 Thereafter 4 Total $ 4,382 Equity Investments The following table summarizes our equity investments as of the dates indicated (in millions): Balance Sheet Location June 30, December 31, Equity investment in Adevinta Equity investment in Adevinta $ — $ 4,474 Equity investment in Aurelia Equity investment in Aurelia 1,910 — Other equity investments under the fair value option Long-term investments 354 382 Other equity investments without readily determinable fair values Long-term investments 134 93 Equity investments under the equity method of accounting Long-term investments 55 55 Total equity investments $ 2,453 $ 5,004 Equity investments under the fair value option Equity Investment in Adevinta Upon completion of the transfer of our Classifieds business to Adevinta in 2021, we received an equity investment of 44% in Adevinta valued at $10.8 billion at the close of the transfer. In the fourth quarter of 2021, we completed the sale of approximately 135 million of our voting shares in Adevinta to Permira, inclusive of the option exercised by Permira to purchase additional voting shares, for total cash consideration of approximately $2.3 billion, which reduced our ownership in Adevinta to 33%. At the initial recognition of this equity investment in Adevinta, we elected the fair value option where subsequent changes in fair value are recognized in loss on equity investments and warrant, net in the condensed consolidated statement of income. The investment was reported within the short-term assets section in our condensed consolidated balance sheet and was classified within Level 1 in the fair value hierarchy as the valuation could be obtained from real time quotes in active markets based on Adevinta’s closing stock price and prevailing foreign exchange rate at each balance sheet date. We believe the fair value option election created more transparency of the current value in the equity investment in Adevinta. Refer to “Note 7 — Fair Value Measurement of Assets and Liabilities” for more information. The fair value of the investment was $4,474 million as of December 31, 2023. On May 29, 2024, we completed the previously announced sale of (1) 227 million Adevinta shares to Aurelia BidCo 1 Norway AS in exchange for approximately $2.4 billion in cash and (2) 177 million Adevinta shares to Aurelia Netherlands TopCo B.V. (“Aurelia”) in exchange for the issuance of 177 million shares of the new entity, Aurelia (collectively, the “Transactions”) valued at $1.9 billion and representing approximately 18.3% ownership of the outstanding equity of Aurelia as of the date of the Transactions. The equity investment in Aurelia is accounted for under the measurement alternative as we are not able to exercise significant influence based on the governance structure defined in the terms of the Transaction Completion Agreement and the Aurelia Shareholder Agreement. Refer to "Equity investments without readily determinable fair values” below for additional information. For the three months ended June 30, 2024, we recorded a realized gain of $84 million to loss on equity investments and warrant, net on our condensed consolidated statement of income related to the sale of the investment in Adevinta. For the six months ended June 30, 2024, an unrealized loss of $234 million and a realized gain on sale of $78 million were recorded in loss on equity investments and warrant, net on our condensed consolidated statement of income related to the sale of the investment in Adevinta. In connection with the Transactions, as of June 30, 2024 we reduced deferred tax liabilities by $456 million and increased income taxes payable by $458 million on our condensed consolidated balance sheet related to the taxable gain on disposition of Adevinta shares. For the three and six months ended June 30, 2023, unrealized losses of $210 million and $36 million, respectively, were recorded in loss on equity investments and warrant, net on our condensed consolidated statement of income related to the change in fair value of the investment in Adevinta. Other equity investments under the fair value option Equity investment in Gmarket In 2021, we completed the sale of 80.01% of the outstanding equity interests of eBay Korea to Emart. Upon completion of the sale, we retained 19.99% of the outstanding equity interest of the new entity, Gmarket, over whom we are able to exercise significant influence based on the terms of the securities purchase agreement, including through our board representation. Our equity investment in Gmarket was valued at $728 million as of the transaction close date. At the initial recognition of this equity investment, we elected the fair value option where subsequent changes in fair value are recognized in loss on equity investments and warrant, net in the condensed consolidated statement of income. The investment is reported within long-term investments in our condensed consolidated balance sheet and is classified within Level 3 in the fair value hierarchy as the valuation reflects management’s estimate of assumptions that market participants would use in pricing the equity investment. We believe the fair value option election creates more transparency of the current value in the equity investment in Gmarket. Refer to “Note 7 — Fair Value Measurement of Assets and Liabilities” for more information. For the three and six months ended June 30, 2024, unrealized losses related to the change in fair value of the investment of $22 million and $28 million, respectively, were recorded in loss on equity investments and warrant, net on our condensed consolidated statement of income compared to $29 million and $40 million of unrealized losses recorded during the same periods in 2023. The fair value of the investment was $307 million and $335 million as of June 30, 2024 and December 31, 2023, respectively. Other investments Certain other individually immaterial equity investments aggregating to $47 million as of both June 30, 2024 and December 31, 2023 are measured at fair value using the net asset value per share (or its equivalent) practical expedient, and have not been classified in the fair value hierarchy. Refer to “Note 7 — Fair Value Measurement of Assets and Liabilities” for more information. Equity investments without readily determinable fair values Equity investments without readily determinable fair values are non-marketable equity securities, which are investments in privately-held companies for which we do not exercise significant influence and are accounted for under the measurement alternative. Under the measurement alternative, the carrying value is measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Changes in value and impairments of equity investments without readily determinable fair values are recognized in loss on equity investments and warrant, net in our condensed consolidated statement of income. Equity investments without readily determinable fair values are presented within long-term investments in our condensed consolidated balance sheet. Equity investment in Aurelia As discussed in the Equity Investment in Adevinta section above, our equity investment in Aurelia is accounted for under the measurement alternative as we are not able to exercise significant influence over Aurelia. For the three and six months ended June 30, 2024, no downward adjustments to the carrying value of our equity investment in Aurelia were recorded. The carrying value of the investment was $1.9 billion as of June 30, 2024. In connection with the Transactions discussed above, we also granted Aurelia UK Feederco Limited a six month option to purchase Aurelia shares (the "Aurelia Option"), which, if exercised, would reduce our ownership in Aurelia to approximately 8.3% based on the outstanding equity of Aurelia as of the date of the Transactions. The Aurelia Option is reported within the current liabilities section in our condensed consolidated balance sheet and is classified within Level 3 in the fair value hierarchy as the valuation reflects management’s estimate of assumptions that market participants would use in pricing the equity investment. The Aurelia Option was valued at $109 million as of June 30, 2024. Refer to “Note 7 — Fair Value Measurement of Assets and Liabilities” for more information. Other equity investments without readily determinable fair values For the three and six months ended June 30, 2024, we recorded additions of $41 million compared to immaterial additions during the same periods in 2023. The change in value of our other equity method investments without readily determinable fair values for each of the three and six-month periods ended June 30, 2024 and 2023 was immaterial both individually and in the aggregate. Other equity method investments We account for certain other individually immaterial equity investments through which we exercise significant influence but do not have control over the investee under the equity method. Our consolidated results of operations include, as a component of interest income and other, net, our share of the net income or loss of the equity investments. Equity method investments are presented within long-term investments in our condensed consolidated balance sheet. Our share of the net income or loss of equity method investments for each of the three and six-month periods ended June 30, 2024 and 2023 was immaterial both individually and in the aggregate. Gains and losses on equity investments The following table summarizes unrealized gains and losses on equity investments held as of June 30, 2024 and presented within loss on equity investments and warrant, net for the periods indicated (in millions): Three Months Ended Six Months Ended 2024 2023 2024 2023 Net gains (losses) recognized during the period on equity investments $ 61 $ (245) $ (185) $ (85) Less: Net gains recognized during the period on equity investments sold during the period 84 — 78 — Total unrealized losses on equity investments held, end of period $ (23) $ (245) $ (263) $ (85)

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments Our primary objective in holding derivatives is to reduce the volatility of earnings and cash flows associated with changes in foreign currency exchange rates and interest rates. These hedging contracts reduce, but do not entirely eliminate, the impact of adverse foreign exchange rate and interest rate movements. We do not use any of our derivative instruments for trading purposes. We use foreign currency exchange contracts to reduce the volatility of cash flows related to forecasted revenues, expenses, assets and liabilities, including intercompany balances denominated in foreign currencies. These contracts are generally one month to one year in duration but with maturities up to 24 months. The objective of the foreign exchange contracts is to ensure that ultimately the U.S. dollar-equivalent cash flows are not adversely affected by changes in the applicable U.S. dollar/foreign currency exchange rate. We evaluate the effectiveness of our foreign exchange contracts designated as cash flow or net investment hedges on a quarterly basis. Cash Flow Hedges For derivative instruments that are designated as cash flow hedges, the derivative’s gain or loss is initially reported as a component of accumulated other comprehensive income (“AOCI”) and subsequently reclassified into earnings in the same period the forecasted hedged transaction affects earnings. Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur in the initially identified time period or within a subsequent two-month time period. Unrealized gains and losses in AOCI associated with such derivative instruments are immediately reclassified into earnings . As of June 30, 2024, we have estimated that approximately $28 million of net derivative losses related to our foreign exchange cash flow hedges and $8 million of net derivative gains related to our interest rate cash flow hedges included in AOCI will be reclassified into earnings within the next 12 months. We classify cash flows related to our cash flow hedges as operating activities in our condensed consolidated statement of cash flows. Non-Designated Hedges Our derivatives not designated as hedging instruments consist of foreign currency forward contracts that we primarily use to hedge monetary assets or liabilities, including intercompany balances and equity investments denominated in non-functional currencies. The gains and losses on our derivatives not designated as hedging instruments are recorded in interest income and other, net, which are offset by the foreign currency gains and losses on the related assets and liabilities that are also recorded in interest income and other, net. We classify cash flows related to our non-designated hedging instruments in the same line item as the cash flows of the related assets or liabilities, which is generally within operating activities in our condensed consolidated statement of cash flows. Cash flows related to the settlement of non-designated hedging instruments related to equity investments are classified within investing activities in our condensed consolidated statement of cash flows. Warrant We entered into a warrant agreement in conjunction with a commercial agreement with Adyen N.V. (“Adyen”) that, subject to meeting certain conditions, entitles us to acquire a fixed number of shares up to 5% of Adyen’s fully diluted issued and outstanding share capital at a specific date. The warrant has a term of seven years and vests in a series of four tranches, at a specified price per share (fixed for the first two tranches) upon meeting processing volume milestone targets on a calendar year basis. When or if a relevant milestone is reached, the warrant becomes exercisable with respect to the corresponding tranche of warrant shares up until the warrant expiration date of January 31, 2025. The maximum number of tranches that can vest in one calendar year is two. The warrant is accounted for as a derivative under ASC Topic 815, Derivatives and Hedging . We report the warrant at fair value within other current assets in our condensed consolidated balance sheet and changes in the fair value of the warrant are recognized in loss on equity investments and warrant, net in our condensed consolidated statement of income. The day-one value attributable to the other side of the warrant, which was recorded as a deferred credit, is reported within other liabilities in our condensed consolidated balance sheet and is amortized over the life of the commercial arrangement. See “Note 7 — Fair Value Measurement of Assets and Liabilities” for information about the fair value measurement of the warrant.

However, we have elected to present the derivative assets and derivative liabilities on a gross basis in our condensed consolidated balance sheet. As of June 30, 2024, the potential effect of rights of set-off associated with the foreign exchange contracts would be an offset to both assets and liabilities by $7 million, resulting in net derivative assets of $34 million and immaterial net derivative liabilities. As of June 30, 2024, there was no potential effect of rights of set-off associated with the interest rate contracts as there were no asset positions.

Level 1 instrument valuations are obtained from real-time quotes for transactions in active exchange markets involving identical assets. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments, identical instruments in less active markets, or models using market observable inputs. Level 3 instrument valuations typically reflect management’s estimate of assumptions that market participants would use in pricing the asset or liability. We did not have any transfers of financial instruments between valuation levels during the six months ended June 30, 2024. Other financial instruments, including accounts receivable, funds receivable, accounts payable and funds payable, are carried at cost, which approximates their fair value because of the short-term nature of these instruments. Fair value measurement of derivative instruments The majority of our derivative instruments are valued using pricing models that take into account the contract terms as well as multiple inputs where applicable, such as equity prices, interest rate yield curves, option volatility and currency rates. Our warrant, which is accounted for as a derivative instrument, is valued using a Black-Scholes model. Key assumptions used in the valuation include risk-free interest rates, Adyen’s common stock price, equity volatility and common stock outstanding, exercise price, and details specific to the warrant. The value is also probability adjusted for management’s assumptions with respect to vesting of the remaining three tranches which are each subject to meeting processing volume milestone targets. These assumptions and the probability of meeting processing volume milestone targets may have a significant impact on the value of the warrant. Refer to “Note 6 — Derivative Instruments” for further details on our derivative instruments. The following table presents a reconciliation of the opening to closing balance of assets measured using significant unobservable inputs (Level 3) as of the dates indicated (in millions): June 30, December 31, Opening balance at beginning of period $ 364 $ 214 Change in fair value (25) 150 Closing balance at end of period $ 339 $ 364 The following table presents quantitative information about Level 3 significant unobservable inputs used in the fair value measurement of the warrant as of June 30, 2024 (in millions, except percentages): Fair value Valuation technique Unobservable Input (1) Range (weighted average) Warrant $ 339 Black-Scholes and Monte Carlo Probability of vesting 0.0% - 95.0% (78.4%) Equity volatility (44%) (1) Probability of vesting was weighted by the unadjusted value of the tranches. For volatility, the average represents the arithmetic average of the points within the range and is not weighted by the relative fair value or notional amount. Fair value measurement of equity investments Certain equity investments are measured at fair value on a recurring basis, including our equity investment in Adevinta and equity investments under the fair value option. Our equity investment in Adevinta was accounted for under the fair value option and classified within Level 1 in the fair value hierarchy as the fair value was measured based on Adevinta’s closing stock price and prevailing foreign exchange rate at each balance sheet date. Our equity investment in Gmarket is accounted for under the fair value option. The following table presents a reconciliation of the opening to closing balance of the equity investment in Gmarket measured using significant unobservable inputs (Level 3) as of the dates indicated (in millions): June 30, December 31, Opening balance at beginning of period $ 335 $ 431 Change in fair value (28) (96) Closing balance at end of period $ 307 $ 335 This investment is classified within Level 3 in the fair value hierarchy as valuation of the investment reflects management’s estimate of assumptions that market participants would use in pricing the asset. The following table presents quantitative information about Level 3 significant unobservable inputs used in the fair value measurement of the equity investment in Gmarket as of June 30, 2024 that may have a significant impact on the overall valuation (in millions, except multiples): Fair value Valuation technique Unobservable Input (1) Range Equity investment in Gmarket $ 307 Market multiples Revenue multiple — GPC method 0.7x — 1.7x Revenue multiple — GMAC method 1.0x — 2.7x (1) The primary unobservable inputs used in the fair value measurement of our equity investment in Gmarket under the fair value option, when using the Guideline Public Company (GPC) method and the Guideline Merged and Acquired Company (GMAC) method under the market multiple approach, are the respective revenue multiples. Significant increases (decreases) in the revenue multiples in isolation would result in significantly higher (lower) fair value measurement. The market multiples are derived from respective groups of guideline public companies and guideline merged and acquired companies. Certain other immaterial equity investments under the fair value option aggregating to $47 million as of both June 30, 2024 and December 31, 2023 are measured at fair value using the net asset value per share (or its equivalent) practical expedient, and have not been classified in the fair value hierarchy. Refer to “Note 5 — Investments” for further details about our equity investments. Fair value measurement of Aurelia Option In connection with the Transactions discussed in “Note 5 — Investments”, we granted Aurelia UK Feederco Limited the Aurelia Option, which, if exercised, would reduce our ownership in Aurelia to approximately 8.3% based on the outstanding equity of Aurelia as of the date of the Transactions. The Aurelia Option is valued using a Black-Scholes model where key inputs and assumptions used in the valuation include risk-free interest rates, the common stock price as of June 30, 2024, equity volatility, exercise price, and details specific to the Aurelia Option. The Aurelia Option is reported within the current liabilities section in our condensed consolidated balance sheet and is classified within Level 3 in the fair value hierarchy as the valuation reflects management’s estimate of assumptions that market participants would use in pricing the equity investment. The Aurelia Option was valued at $109 million as of June 30, 2024.

Senior Notes On August 1, 2024, we repaid the $750 million aggregate principal amount of our previously outstanding 3.450% senior notes on the date of maturity. In January 2023, we repaid the $1.2 billion aggregate principal amount of our previously outstanding floating rate and 2.750% senior notes on the date of maturity . Total cash consideration paid was $1.2 billion, as the redemption price was equal to 100% of the principal amount. In addition, we paid accrued and unpaid interest on the principal amount. We may redeem some or all of the notes of each series at any time and from time to time prior to their maturity, generally at a make-whole redemption price, plus accrued and unpaid interest. If a change of control triggering event (as defined in the applicable series of notes) occurs with respect to the 3.450% notes due 2024, the 1.900% notes due 2025, the 5.900% notes due 2025, the 1.400% notes due 2026, the 3.600% notes due 2027, the 5.950% notes due 2027, the 2.700% notes due 2030, the 2.600% notes due 2031, the 6.300% notes due 2032, the 4.000% notes due 2042, or the 3.650% notes due 2051, we must, subject to certain exceptions, offer to repurchase all of the notes of the applicable series at a price equal to 101% of the principal amount, plus accrued and unpaid interest. The indenture pursuant to which the senior notes were issued includes customary covenants that, among other things and subject to exceptions, limit our ability to incur, assume or guarantee debt secured by liens on specified assets or enter into sale and lease-back transactions with respect to specified properties, and also includes customary events of default with customary grace periods in certain circumstances, including payment defaults and bankruptcy-related defaults. The effective interest rates for our senior notes include the interest payable, the amortization of debt issuance costs and the amortization of any original issue discount and premium on these senior notes. Interest on these senior notes is payable either quarterly or semiannually. Interest expense associated with these senior notes, including amortization of debt issuance costs, was approximately $64 million and $129 million during the three and six months ended June 30, 2024 compared to $64 million and $131 million during the same periods in 2023. As of June 30, 2024 and December 31, 2023, the estimated fair value of these senior notes, using Level 2 inputs, was approximately $7.0 billion and $7.1 billion, respectively. Commercial Paper We have a commercial paper program pursuant to which we may issue commercial paper notes in an aggregate principal amount at maturity of up to $1.5 billion outstanding at any time with maturities of up to 397 days from the date of issue. As of June 30, 2024 and December 31, 2023, there were no commercial paper notes outstanding. Credit Agreement In March 2020, we entered into a credit agreement that provided for an unsecured $2 billion five-year credit facility (the “Prior Credit Agreement”). In January 2024, we terminated the Prior Credit Agreement and entered into a new credit agreement (the “Credit Agreement”) that provides for an unsecured $2.0 billion five-year revolving credit facility. We may also, subject to the agreement of the applicable lenders, increase the commitments under the revolving credit facility by up to $1.0 billion. Funds borrowed under the Credit Agreement may be used for working capital, capital expenditures, acquisitions and other general corporate purposes and will bear interest at either (i) a customary forward-looking term rate based on the secured overnight financing rate published by CME Group for the relevant interest period plus an adjustment of 0.1% or (ii) a customary base rate formula, plus a margin (based on our public debt ratings) ranging from 0% to 0.375%. As of June 30, 2024, no borrowings were outstanding under our $2.0 billion Credit Agreement. However, as described above, we have an up to $1.5 billion commercial paper program and are required to maintain available borrowing capacity under our Credit Agreement in order to repay commercial paper borrowings in the event we are unable to repay those borrowings from other sources when they become due, in an aggregate amount of $1.5 billion. As of June 30, 2024, no borrowings were outstanding under our commercial paper program; therefore, $2.0 billion of borrowing capacity was available for other purposes permitted by the Credit Agreement, subject to customary conditions to borrowing. The Credit Agreement includes a covenant limiting our consolidated leverage ratio to no more than 4.0:1.0, subject to, upon the occurrence of a qualified material acquisition, if so elected by us, a step-up to 4.5:1.0 for the four fiscal quarters completed following such qualified material acquisition. The Credit Agreement includes customary events of default, with corresponding grace periods in certain circumstances, including payment defaults, cross-defaults and bankruptcy-related defaults. In addition, the Credit Agreement contains customary affirmative and negative covenants, including restrictions regarding the incurrence of liens and subsidiary indebtedness, in each case, subject to customary exceptions. The Credit Agreement also contains customary representations and warranties. We were in compliance with all financial covenants in our outstanding debt instruments during the six months ended June 30, 2024.

Balance Sheet Components [Abstract]
Supplemental Consolidated Financial Information	Supplemental Consolidated Financial Information Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable represents amounts invoiced and revenue recognized prior to invoicing when we have satisfied our performance obligation and have the unconditional right to payment. The allowance for doubtful accounts and authorized credits is estimated based upon our assessment of various factors including historical experience, the age of the accounts receivable balances, current economic conditions reasonable and supportable forecasts, and other factors that may affect our customers’ ability to pay. The allowance for doubtful accounts and authorized credits was $45 million and $49 million as of June 30, 2024 and December 31, 2023, respectively. As of June 30, 2024, we reported an allowance for doubtful accounts of $22 million, reflecting a decrease of $1 million, net of write-offs of $11 million for the six months ended June 30, 2024. As of June 30, 2024, we reported an allowance for authorized credits of $23 million, reflecting a decrease of $3 million, net of write-offs of $5 million for the six months ended June 30, 2024. As of December 31, 2023, we reported an allowance for doubtful accounts of $23 million and an allowance for authorized credits of $26 million. Deferred revenue consists of fees received related to unsatisfied performance obligations at the end of the period. Due to the generally short-term duration of contracts, the majority of the performance obligations are satisfied in the following reporting period. The amount of revenue recognized for the six months ended June 30, 2024 that was included in the deferred revenue balance at the beginning of the period was $30 million. The amount of revenue recognized for the six months ended June 30, 2023 that was included in the deferred revenue balance at the beginning of the period was $31 million.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Off-Balance Sheet Arrangements As of June 30, 2024, we had no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future material effect on our consolidated financial condition, results of operations, liquidity, capital expenditures or capital resources. Litigation and Other Legal Matters We are involved in legal and regulatory proceedings on an ongoing basis. If we believe that a loss arising from such matters is probable and can be reasonably estimated, we accrue the estimated liability in our financial statements. If only a range of estimated losses can be determined, we accrue an amount within the range that, in our judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we accrue the low end of the range. For those proceedings in which an unfavorable outcome is reasonably possible but not probable, we have disclosed an estimate of the reasonably possible loss or range of losses or we have concluded that an estimate of the reasonably possible loss or range of losses arising directly from the proceeding (i.e., monetary damages or amounts paid in judgment or settlement) is not material. If we cannot estimate the probable or reasonably possible loss or range of losses arising from a proceeding, we have disclosed that fact. In assessing the materiality of a proceeding, we evaluate, among other factors, the amount of monetary damages claimed, as well as the potential impact of non-monetary remedies sought by plaintiffs (e.g., injunctive relief) that may require us to change our business practices in a manner that could have a material adverse impact on our business. Legal fees are expensed as incurred. On September 27, 2023, the U.S. Department of Justice, on behalf of the Environmental Protection Agency, filed a civil complaint in the U.S. District Court for the Eastern District of New York alleging that the Company is liable for the sale of regulated or illicit products manufactured and sold by third parties who listed such products on the Marketplace platforms in a manner that evaded and/or was designed to evade detection by the Company and in violation of the Clean Air Act, Federal Insecticide, Fungicide, and Rodenticide Act and the Toxic Substances Control Act. The Company intends to vigorously defend against these claims. If the Company is found to be liable for such activities on the Marketplace, it likely will be subject to monetary damages, changes in our business practices, or other remedies that could have a material adverse impact on our business. The Company is unable to predict whether additional litigation or proceedings may arise out of this matter. In connection with litigation and other legal matters for which we believe a loss is probable, the Company has accrued for estimated losses of $67 million in the aggregate as of June 30, 2024. Given the uncertainties involved, the ultimate resolution of these matters could result in additional losses that may be material to our financial results for a particular period, depending on, among other factors, the size of the loss or liability imposed and the level of our net income or loss for that period. Indemnification Provisions We entered into a separation and distribution agreement and various other agreements with PayPal to govern the separation and relationship of the two companies. These agreements provide for specific indemnity and liability obligations and could lead to disputes between us and PayPal, which may be significant. In addition, the indemnity rights we have against PayPal under the agreements may not be sufficient to protect us and our indemnity obligations to PayPal may be significant. In addition, we have entered into indemnification agreements with each of our directors, executive officers and certain other officers. These agreements require us to indemnify such individuals, to the fullest extent permitted by Delaware law, for certain liabilities to which they may become subject as a result of their affiliation with us. In the ordinary course of business, we have included limited indemnification provisions in certain of our agreements with parties with which we have commercial relations, including our standard marketing, promotions and application programming interface license agreements. Under these contracts, we may indemnify, hold harmless and agree to reimburse the indemnified party for losses suffered or incurred by the indemnified party in connection with claims by a third party with respect to intellectual property infringement, including to our trademarks, logos and proprietary software, and other branding elements, such as domain names, to the extent that such are applicable to our performance under the subject agreement. In certain cases, we have agreed to provide indemnification for gross negligence, willful misconduct, fraud and breach of representations, warranties and applicable law. It is not possible to determine the maximum potential loss under these indemnification provisions due to our limited history of prior indemnification claims and the unique facts and circumstances involved in each particular provision. To date, losses recorded in our consolidated statement of income in connection with our indemnification provisions have not been significant, either individually or collectively.

Equity [Abstract]
Stockholders’ Equity	Stockholders’ Equity Stock Repurchase Program Our stock repurchase programs are intended to programmatically offset the impact of dilution from our equity compensation programs and, subject to market conditions and other factors, to make opportunistic and programmatic repurchases of our common stock to reduce our outstanding share count. Any share repurchases under our stock repurchase programs may be made through open market transactions, block trades, privately negotiated transactions (including accelerated share repurchase transactions) or other means at times and in such amounts as management deems appropriate and will be funded from our working capital or other financing alternatives. Our stock repurchase programs may be limited or terminated at any time without prior notice. The timing and actual number of shares repurchased will depend on a variety of factors, including corporate and regulatory requirements, price and other market conditions and management’s determination as to the appropriate use of our cash. In February 2024, our Board of Directors (our “Board”) authorized an incremental $2.0 billion under our stock repurchase program in addition to the $4.0 billion previously authorized in 2022. The stock repurchase program has no expiration from the date of authorization. The following table summarizes stock repurchase activity under our stock repurchase programs for the period indicated (in millions, except per share amounts): Shares Repurchased (1) Average Price per Share (2) Value of Shares Repurchased (2) Remaining Amount Authorized Balance as of January 1, 2024 $ 1,447 Authorization of additional repurchases in February 2024 2,000 Repurchase of shares of common stock 29 $ 51.88 $ 1,499 (1,499) Balance as of June 30, 2024 $ 1,948 (1) These repurchased shares of common stock were recorded as treasury stock and were accounted for under the cost method. None of the repurchased shares of common stock have been retired. (2) Excludes broker commissions and excise tax accruals. Dividends The Company paid a total of $135 million and $133 million in cash dividends during the three months ended June 30, 2024 and 2023, respectively, and $274 million and $267 million in cash dividends during the six months ended June 30, 2024 and 2023, respectively. In July 2024, our Board declared a cash dividend of $0.27 per share of common stock to be paid on September 13, 2024 to stockholders of record as of August 30, 2024.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes We are subject to both direct and indirect taxation in the U.S. and various states and foreign jurisdictions. We are under examination by certain tax authorities for the 2010 to 2022 tax years. We believe that adequate amounts have been reserved for any adjustments that may ultimately result from these or other examinations. The material jurisdictions where we are subject to potential examination by tax authorities for tax years after 2009 include, among others, the U.S. (Federal and California), Germany, India, Israel, Switzerland and the United Kingdom. Although the timing of the resolution and/or closure of audits is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. However, given the number of years remaining subject to examination and the number of matters being examined, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. We have recognized the tax consequences of all foreign unremitted earnings and management has no specific plans to indefinitely reinvest the unremitted earnings of our foreign subsidiaries as of the balance sheet date. As of June 30, 2024, $292 million of our liability for deemed repatriation of foreign earnings was included in income taxes payable on our condensed consolidated balance sheet. As of December 31, 2023, $292 million of our liability for deemed repatriation of foreign earnings was included in other liabilities on our condensed consolidated balance sheet. We have not provided for deferred taxes on outside basis differences in our investments in our foreign subsidiaries that are unrelated to unremitted earnings. These basis differences will be indefinitely reinvested. A determination of the unrecognized deferred taxes related to these other components of our outside basis difference is not practicable.

His 10b5-1 Plan calls for potential sales from time to time of a portion of his shares, as well as the sale of a percentage of shares that he could receive upon the future vesting of certain outstanding equity awards, net of any shares withheld by us to satisfy applicable taxes. The number of shares to be withheld, and thus the exact maximum number of shares to be sold pursuant to Mr. Priest’s 10b5-1 Plan, can only be determined upon the occurrence of the future vesting events. For purposes of this disclosure, without subtracting any shares to be withheld upon future vesting events, the maximum aggregate number of shares to be sold pursuant to Mr. Priest’s 10b5-1 Plan is 64,129.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, we evaluate our estimates, including but not limited to those related to provisions for transaction losses, legal contingencies, income taxes, revenue recognition, stock-based compensation, investments including level 3 investments in Gmarket Global LLC (“Gmarket”), warrants and the recoverability of goodwill and intangible assets. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from those estimates. We review the useful lives of equipment on an ongoing basis, and effective January 1, 2024 we changed our estimate of the useful lives for our servers and networking equipment from three years to four years. The longer useful lives are due to continuous improvements in our hardware, software, and data center designs.

Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying financial statements are consolidated and include the financial statements of eBay Inc. and our wholly and majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Minority interests are recorded as a noncontrolling interest. A qualitative approach is applied to assess the consolidation requirement for variable interest entities. Generally, investments in entities where we hold at least a 20% ownership interest and have the ability to exercise significant influence, but not control, over the investee are accounted for using the equity method of accounting, including those in which the fair value option has been elected. For equity method investments, our share of the investees’ results of operations is included in interest income and other, net and investment balances are included in long-term investments. For equity method investments under the fair value option, the change in fair value of the investment is included in loss on equity investments and warrant, net and investment balances are included in long-term investments, other than our equity interest in Adevinta ASA (“Adevinta”), which was included in the short-term assets section on the condensed consolidated balance sheet as of December 31, 2023 as discussed in “Note 5 — Investments.” Investments in entities where we hold less than a 20% ownership interest are generally accounted for as equity investments to be measured at fair value, under an election, or at cost if it does not have readily determinable fair value, in which case the carrying value would be adjusted upon the occurrence of an observable price change in an orderly transaction for identical or similar instruments or impairment. These condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”). We have evaluated all subsequent events through the date these condensed consolidated financial statements were issued. In the opinion of management, these condensed consolidated financial statements reflect all adjustments, consisting only of normal recurring adjustments, which are necessary for the fair statement of the condensed consolidated financial position, results of operations and cash flows for these interim periods. Effective January 1, 2024, certain immaterial prior period balances have been reclassified to conform to the current period presentation in the condensed consolidated financial statements and the accompanying notes. Specifically, immaterial restricted cash balances previously reported as components of short-term and long-term investments are now reported within the other current assets and other assets sections, respectively, in our condensed consolidated balance sheet.
Customer accounts and funds receivable	Customer accounts and funds receivable Customer accounts represent cash received from buyers that is held by financial institutions. Due to safeguarding requirements in certain regions, a portion of this balance is considered restricted. Funds receivable represents customer cash in transit and held by payment processors. These balances are associated with marketplace activity and are awaiting payment to sellers.
Cash, cash equivalents and restricted cash	Cash, cash equivalents and restricted cash Cash and cash equivalents are short-term, highly liquid investments with original maturities of three months or less when purchased, which may include bank deposits, U.S. Treasury securities, time deposits, and certificates of deposit. We consider cash to be restricted when withdrawal or general use is legally restricted. Restricted cash is held in interest bearing accounts for letters of credit related to our global sabbatical program and for certain amounts related to other compensation arrangements held in escrow. We also hold restricted cash in segregated bank accounts for purposes of safeguarding customer funds.
Recent Accounting Pronouncements Not Yet Adopted	Recent Accounting Pronouncements Not Yet Adopted In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07—Segment Reporting (Topic 280): Improvements to Reportable Segments Disclosures. The new guidance is intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses enabling investors to better understand an entity’s overall performance and assess potential future cash flows. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The standard will be effective for annual reporting periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-08—Intangibles—Goodwill and Other—Crypto Assets (Subtopic 350-60): Accounting for and Disclosure of Crypto Assets. The new guidance addresses the accounting and disclosure requirements for certain crypto assets and requires entities to subsequently measure certain crypto assets at fair value, with changes in fair value recorded in net income in each reporting period. In addition, entities are required to provide additional disclosures about the holdings of certain crypto assets. The standard is effective for annual reporting periods beginning after December 15, 2024, including interim reporting periods within those fiscal years. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements. In December 2023, the FASB issued ASU 2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The new guidance is intended to further standardize income tax disclosures primarily related to the presentation of the effective tax rate reconciliation and income taxes paid information in our financial statements and disclosures. The standard is effective for annual reporting periods beginning after December 15, 2024. We do not expect the adoption of this standard to have a material impact on our consolidated financial statements.
