Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The accompanying condensed consolidated financial statements have been prepared in accordance with GAAP.
Principles of Consolidation | Principles of Consolidation The condensed consolidated financial statements include the accounts of Datadog, Inc. and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates | Use of Estimates The preparation of condensed consolidated 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. Such estimates include the fair value of marketable securities, the allowance for credit losses, the fair value of acquired assets and assumed liabilities from business combinations, useful lives of property, equipment, software and finite lived intangibles, stock-based compensation, valuation of long-lived assets and their recoverability, including goodwill, the incremental borrowing rate for operating leases, estimated expected period of benefit for deferred contract costs, fair value of the liability component of the convertible debt, realization of deferred tax assets and uncertain tax positions, revenue recognition and the allocation of overhead costs between cost of revenue and operating expenses. The Company bases its estimates on historical experience and also on assumptions that management considers reasonable. The Company assesses these estimates on a regular basis; however, actual results could materially differ from these estimates. In January 2025, the Company completed an assessment of the useful life of its capitalized software development costs, resulting in an increase in the estimated useful life of capitalized software development costs from two to three years. This change in accounting estimate was effective beginning fiscal year 2025.
Accounting Pronouncements Not Yet Adopted | Accounting Pronouncements Not Yet Adopted In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU No. 2023-09”), which intends to increase the transparency of income tax disclosures, particularly the rate reconciliation table and disclosures about income taxes paid. For public business entities, it is effective for annual periods beginning after December 15, 2024, and interim periods beginning after December 15, 2025, with early adoption permitted. The Company has not early adopted this standard and is evaluating the impact of it on its consolidated financial statements for the year ended December 31, 2025. In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40) ("ASU No. 2024-03"), which requires disaggregated disclosure of income statement expenses for public business entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. For public business entities, it is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments in this ASU should be applied prospectively, however, public business entities are permitted to apply the amendments in the ASU retrospectively. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements.
