Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Principles of Consolidation | Principles of Consolidation The Condensed Consolidated Financial Statements include the accounts of Groupon, Inc. and its wholly-owned subsidiaries, majority-owned subsidiaries over which we exercise control and variable interest entities for which we are the primary beneficiary. All intercompany accounts and transactions have been eliminated in consolidation. Outside stockholders' interests in subsidiaries are shown in the Condensed Consolidated Financial Statements as Noncontrolling interests. Investments in entities in which we do not have a controlling financial interest are accounted for at fair value as available-for-sale securities or at cost adjusted for observable price changes and impairments, as appropriate.
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Estimates in our financial statements include, but are not limited to, the following: variable consideration from unredeemed vouchers; income taxes; stock-based compensation; leases; initial valuation and subsequent impairment testing of goodwill, other intangible assets and long-lived assets; investments; receivables; customer credits, customer refunds and other reserves; contingent liabilities; and the useful lives of property, equipment and software and intangible assets. Actual results could differ materially from those estimates.
Reclassifications | Reclassifications Certain reclassifications have been made to the Condensed Consolidated Financial Statements of prior periods to conform to the current period presentation.
Adoption of New Accounting Standards and Recently Issued Accounting Standards | Adoption of New Accounting Standards There were no new accounting standards adopted during the six months ended June 30, 2026. Recently Issued Accounting Standards In November 2024, the FASB issued ASU 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027 and early adoption is permitted.

In September 2025, the FASB issued ASU 2025-06 Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU removes all references to project stages in ASC Subtopic 350-40, clarifies the threshold to begin capitalizing costs and specifies that the property, plant and equipment disclosure requirements under ASC Subtopic 360-10 apply to all capitalized software costs accounted for under ASC Subtopic 350-40. The amendments in this update are effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods beginning after December 15, 2028 and early adoption is permitted. The Company is assessing the effect this guidance may have on our consolidated financial statements.
