Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Proceedings and Loss Contingencies The Company records an accrued liability for contingent losses that it determines are probable and estimable. Contingent losses that the Company evaluates primarily include potential costs related to supply contracts, which can be a result of changing demand forecasts, design modifications, or other causes, 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 June 30, 2026, the Company recorded approximately $350 million and $60 million, respectively, for estimated contingent losses in “Accrued liabilities” on the Condensed Consolidated Balance Sheets. As of June 30, 2026, the Company estimates it is reasonably possible that losses in excess of the accrued liability could occur, up to approximately $90 million, or an excess of $30 million over the accrued liability recorded. The Company expects the majority of contingent losses comprising the accrued liability to be resolved within the next 12 to 24 months. 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, which was fully funded into escrow by the Company and insurance carriers by January 2026. After receipt in full of all corresponding insurance recoveries, the aggregate net settlement payment made by the Company was $181 million. The Court issued its Order granting final approval of the proposed settlement and Judgment was entered in May 2026.
