Accounting Policies [Abstract] |
Basis of Presentation | The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany account balances and transactions have been eliminated upon consolidation. The unaudited condensed consolidated financial statements were prepared in accordance with the United States (“U.S.”) Generally Accepted Accounting Principles (“GAAP”) for interim financial information and with the instructions to Quarterly Report on Form 10‑Q and Article 10 of Regulation S-X. As permitted under those rules, certain footnotes or other financial information may be condensed or omitted.
Use of Estimates | The preparation of consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts that are reported in the consolidated financial statements and the related disclosures. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include, but are not limited to: the useful lives of property and equipment, allowance for sales returns, breakage on gift cards, stock-based compensation, lease liabilities, and goodwill.
Recently Adopted Accounting Pronouncements and Accounting Pronouncements Not Yet Effective | Recently Adopted Accounting Pronouncements In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. ASU 2025-05 provides a practical expedient that permits entities to assume that conditions existing as of the balance sheet date remain unchanged over the life of the asset when estimating expected credit losses for current accounts receivable and current contract assets. ASU 2025-05 is effective for annual periods beginning after December 15, 2025, including interim periods within those annual periods. The Company adopted ASU 2025-05 as of January 1, 2026, and the adoption did not have a material impact on its consolidated financial statements. Accounting Pronouncements Not Yet Effective In September 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU”) 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which removes stage-based criteria and instead requires capitalization once a project is approved and it is probable that the project will be completed, unless significant development uncertainty exists. ASU 2025-06 is effective for annual periods beginning after December 15, 2027, and interim periods within those annual periods. For the Company, the ASU will be effective for the annual period ending December 31, 2028. Early adoption is permitted. The Company is currently evaluating the potential impact on its consolidated financial statements. 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, which expands disclosures about a public entity’s expenses, including inventory, employee compensation, depreciation, intangible asset amortization, selling expenses and other expense categories. ASU 2024-03 is effective for annual period beginning after December 15, 2026, and interim periods within annual periods beginning after December 15, 2027. For the Company, the ASU will be effective for the annual period ending December 31, 2027. The Company is currently evaluating the potential impact on its consolidated financial statement disclosures. In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative, to amend certain disclosure and presentation requirements for a variety of topics within the ASC. These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on its consolidated financial statements and disclosures.
Segment Reporting | The Company operates under one operating segment and one reportable segment as its chief operating decision maker (“CODM”), who is its Chief Executive Officer, reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources and evaluating financial performance. The Company does not have material intra-entity sales or transfers. The key measure of segment profit or loss that the CODM uses to allocate resources and assess performance is the Company’s net loss, as reported in the condensed consolidated statements of operations. Significant expenses within operating loss, as well as within net loss, include cost of revenue, operations, product and technology, marketing, and sales, general and administrative expenses, which are each separately presented in the condensed consolidated statements of operations. Other segment items within net loss include interest expense, other income, net, and provision for income taxes. The CODM manages the business using consolidated expense information, as well as regularly provided budgeted or forecasted expense information. Assets provided to the CODM are consistent with those reported on the condensed consolidated balance sheets.
Revenue from Loyalty Reward Redemption and Expiration | The Company previously had a customer loyalty program that has since been discontinued. Effective October 1, 2024, customers were no longer able to earn loyalty points and after March 31, 2025, they could no longer redeem any previously accumulated points. As a result, as of June 30, 2026 and December 31, 2025, the Company did not have a deferred revenue liability related to its customer loyalty program. The Company recognized no revenue from loyalty reward redemptions and expirations for the three months ended June 30, 2026 and 2025, and $0 and $1.5 million for the six months ended June 30, 2026 and 2025, respectively. Gift Cards, Site Credits and Seller Payable The Company sells ThredUp gift cards on its e-commerce website and may also convert seller payables and site credits to ThredUp gift cards one year after issuance at the discretion of the Company. ThredUp gift cards do not expire or lose value over periods of inactivity. The Company accounts for gift cards by recognizing a gift card liability at the time a gift card is delivered to the customer. As of June 30, 2026 and December 31, 2025, gift card liabilities of $3.2 million and $3.9 million, respectively, were included in accrued and other current liabilities within the Company’s condensed consolidated balance sheets. Revenue from redemption of gift cards was not material for the three and six months ended June 30, 2026 and 2025. The Company recognizes breakage revenue for the portion of gift card values that are not expected to be redeemed. Breakage revenue is estimated based upon historical customer redemption patterns. Breakage revenue primarily relates to gift cards converted from seller payables and site credits. Judgment is required in determining the appropriate grouping of gift cards for analyzing breakage rates, redemption patterns, and estimating the ultimate value of gift cards not expected to be redeemed. Breakage revenue was $1.1 million and $1.7 million for the three months ended June 30, 2026 and 2025, respectively, and $2.4 million and $3.9 million for the six months ended June 30, 2026 and 2025, respectively. The Company issues site credits for returns, which can be applied toward future charges but may not be converted into cash. Site credits may also be converted to ThredUp gift cards beginning after one year at the discretion of the Company. These credits are recognized as revenue when used. As of June 30, 2026 and December 31, 2025, $4.3 million and $4.1 million, respectively, of such customer site credits were included in accrued and other current liabilities within the Company’s condensed consolidated balance sheets. Revenue recognized from the redemption of site credits was $11.4 million and $12.9 million for the three months ended June 30, 2026 and 2025, respectively, and $22.7 million and $23.9 million for the six months ended June 30, 2026 and 2025, respectively.
Seller Payable | Seller payable includes amounts owed to sellers upon the purchase of sellers’ goods by the Company or by buyers. Amounts are initially provided as a credit to sellers (“seller credits”). These credits may be applied towards purchases from the Company, converted to third-party retailer or ThredUp gift cards or redeemed for cash.
Financial Instruments and Fair Value Measurements | The Company applies the provisions of FASB ASC Topic 820, Fair Value Measurements and Disclosures, for its financial and non-financial assets and liabilities. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a fair value hierarchy, which prioritizes the inputs used in measuring fair value into three broad levels as follows: •Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. •Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means. •Level 3 inputs are unobservable inputs for the asset or liability. For the Company’s marketable securities, which were all classified as available-for-sale, the Company utilizes third-party pricing services to obtain fair value. Third-party pricing methodologies incorporate bond terms and conditions, current performance data, proprietary pricing models, real-time quotes from contributing dealers, trade prices and other market data. The Company determined that the declines in the fair value of its marketable securities were not driven by credit-related factors. During the three and six months ended June 30, 2026 and 2025, the Company did not recognize any losses on its marketable securities due to credit-related factors. As of June 30, 2026, the Company’s money market funds were valued using Level 1 inputs because they were valued using quoted prices in active markets. The Company’s commercial paper, corporate debt securities, U.S. government agency bonds and U.S. treasury securities were valued using Level 2 inputs because they were valued using quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. Other Fair Value Disclosures As of June 30, 2026 and December 31, 2025, the carrying amounts of the Company’s accounts receivable, other current assets, other assets, accounts payable, seller payable and accrued and other current liabilities approximated their estimated fair values due to their relatively short maturities. Management believes the terms of its long-term variable-rate debt reflect current market conditions for an instrument with similar terms and maturity, and as such, the carrying value of the Company’s long-term debt approximated its fair value as of June 30, 2026 and December 31, 2025.
