| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Any reference in these notes to applicable guidance refers to GAAP as codified in the Accounting Standards Codification (“ASC”) and as amended by Accounting Standards Updates (“ASUs”) issued by the Financial Accounting Standards Board (“FASB”). These condensed consolidated financial statements are unaudited and, in the opinion of management, include all adjustments (consisting only of normal recurring adjustments and accruals) necessary for a fair statement of the results for the periods presented in accordance with GAAP. The year-end condensed consolidated balance sheet data was derived from our audited consolidated financial statements but does not include all disclosures required by GAAP. Operating results for the three and six months ended June 30, 2026 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2026. Certain information and footnote disclosures normally included in the annual consolidated financial statements prepared in accordance with GAAP have been omitted in accordance with the SEC’s rules and regulations for interim reporting. The accompanying unaudited condensed consolidated financial statements and related notes should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2025, which is included in our 2025 Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 Annual Report on Form 10-K”). Our significant accounting policies are disclosed in Note 2 of the consolidated financial statements for the year ended December 31, 2025, which is included in our 2025 Annual Report on Form 10-K. There have been no material changes to our significant accounting policies during the three and six months ended June 30, 2026. |
| Principles of Consolidation | Principles of Consolidation The Company consolidates the financial statements of its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. In February 2026, the Company dissolved its wholly owned Australian subsidiary, Tectonic Therapeutic Pty Ltd. This entity was dissolved as part of a broader corporate initiative intended to streamline operations and reduce administrative costs. As a result, the Company reclassified $0.1 million of cumulative foreign currency translation losses from accumulated other comprehensive loss to other expense during the six months ended June 30, 2026. |
| Use of Estimates | Use of Estimates The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the reporting periods. These estimates are based on historical experience and other assumptions that the Company believes are reasonable under the circumstances. Revisions to estimates are recorded in the period in which the change becomes known. Significant estimates include the valuation of stock-based awards, prepaid and accrued research and development activities, and income taxes. Actual results may differ from these estimates, and such differences could be material to the Company’s financial position and results of operations. |
| Recent Accounting Pronouncements | Recently Adopted Accounting Standards From time to time, new accounting pronouncements are issued by the FASB, or other standard setting bodies and are adopted by the Company as of the specified effective dates. For the three months ended June 30, 2026, there were no newly adopted accounting pronouncements that had a material impact on the condensed consolidated financial statements. |
| Recently Issued Accounting Pronouncements Not Yet Adopted | Recently Issued Accounting Standards Not Yet Adopted In January 2025, the FASB issued ASU No. 2025-01 to clarify the effective date of ASU No. 2024-03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”), which requires disaggregated disclosure of certain income statement captions within the footnotes to the financial statements. ASU 2025-01 requires adoption of the amendments of ASU 2024-03 in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures.
In December 2025, the FASB issued ASU No. 2025-11, Interim Reporting (Topic 270) (“ASU 2025-11”) to clarify the applicability of ASC 270 and improve the organization of the guidance. The ASU clarifies when an entity is subject to interim reporting requirements and establishes disclosure principles for material events occurring since the end of the most recent annual reporting period. ASU 2025-11 is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures.
In December 2025, the FASB issued ASU No. 2025-12, Improvements to Accounting Standards Codification (“ASU 2025-12”), which addresses stakeholder suggestions and makes incremental improvements to GAAP. The amendments clarify guidance, correct errors, and make minor improvements to the Accounting Standards Codification. ASU 2025-12 is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years. The Company is currently evaluating the impact of this standard on its financial statements and related disclosures. |
