Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Proceedings and Loss Contingencies The Company records an accrued liability for loss contingencies that it determines are probable and estimable. Loss contingencies that the Company evaluates primarily include potential costs related to supply contracts, which can be a result of changing demand forecasts or design modifications or other causes, in addition to potential payments resulting from legal proceedings, such as commercial or employment-related litigation, and other events. Although the Company believes it has valid defenses with respect to legal proceedings, as of December 31, 2025 and March 31, 2026, the Company recorded approximately $350 million and $110 million, respectively, for estimated contingent losses in “Accrued liabilities” and “Accounts payable” on the Condensed Consolidated Balance Sheets. As of March 31, 2026, the Company estimates it is reasonably possible that losses in excess of the accrued liability could occur, up to approximately $170 million, or an excess of $60 million over the accrued liability recorded. The Company expects the majority of loss contingencies comprising the accrued liability to be resolved within the next 12 to 24 months. These amounts include the Company's estimates of probable and reasonably possible contingent losses corresponding to all lawsuits alleging securities law claims based on some or all of the facts alleged in the lawsuit described in the following paragraph, including derivative lawsuits. Between March 7, 2022 and April 19, 2022, three alleged stockholders (the “Plaintiffs”) filed lawsuits against Rivian Automotive, Inc., certain of the Company’s officers and directors, and the Company’s initial public offering (“IPO”) underwriters on behalf of a putative class of purchasers of common stock in the Company’s IPO. The three suits were consolidated under the caption Crews v. Rivian Automotive, Inc., et al., 22-cv-01524-JLS-E (C.D. Cal.). The Court issued its Order granting preliminary approval of the corresponding proposed $250 million settlement on December 18, 2025, and as of December 31, 2025, $17 million of the settlement amount was funded into escrow via insurance recoveries. In January 2026, the remaining settlement balance of $233 million was funded into escrow, of which $183 million was funded by the Company and $50 million was funded by insurance recoveries. On April 17, 2026 the Company’s Normal Factory experienced severe weather, and certain buildings and vehicles sustained damage. The Company is currently assessing the impact, which together with anticipated insurance recoveries is not expected to have a material effect on the condensed consolidated financial statements.
