Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Indemnifications The Company enters into indemnification provisions under certain agreements with other parties in the ordinary course of business. In its customer and data center agreements, the Company has agreed to indemnify, defend, and hold harmless the indemnified party for third-party claims and related losses suffered or incurred by the indemnified party from actual or threatened third-party intellectual property infringement claims. For certain large or strategic customers, the Company has agreed to indemnify, defend, and hold harmless the indemnified party for noncompliance with certain additional representations and warranties made by the Company. In addition, the Company indemnifies its officers, directors, and certain key employees while they are serving in good faith in their respective capacities. While the Company has entered into various indemnification agreements, it has not incurred any material costs or claims under these agreements to date, and management does not expect any future claims to have a material adverse effect on the Company's financial position or results of operations. It is not possible to determine the maximum potential amount under these indemnification provisions due to the Company's limited history of prior indemnification claims and the unique facts and circumstances involved in each particular provision. To date, there have been no material claims under any indemnification provisions. Litigation From time to time, the Company may be subject to various proceedings, lawsuits, disputes, or claims in the ordinary course of business. The Company investigates these claims as they arise. On January 12, 2026, a putative class action Raymond Masaitis v. CoreWeave, Inc. et al (the "Securities Action") was filed in the U.S. District Court for the District of New Jersey against the Company and certain of its officers generally alleging that the defendants made false and misleading statements in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder and seeking unspecified damages. On February 10, 2026, two stockholder derivative actions were filed against certain of the Company’s current and former directors and officers in the U.S. District Court for the District of New Jersey and on March 5, 2026, a third stockholder derivative action was filed in the same court (collectively, the “New Jersey Derivative Actions”). On April 1, 2026, the U.S. District Court for the District of New Jersey consolidated the New Jersey Derivative Actions under the name In Re CoreWeave, Inc. S’holder Deriv. Litig. (the "Consolidated Derivative Action") and on May 21, 2026, the court approved a stay of further proceedings until final resolution of the Securities Action. On May 12, 2026, another stockholder derivative action was filed in the U.S. District Court for the District of Delaware (together with the Consolidated Derivative Action, the “Derivative Actions”). The Derivative Actions collectively assert claims purportedly on behalf of the Company against certain of the Company's current and former officers and directors and, as a nominal defendant, the Company, and seek unspecified damages based on substantially the same allegations as the Securities Action. The Company believes that the claims made in the Securities Action and the Derivative Actions are without merit and intends to defend itself vigorously. Any possible loss or range of loss in these matters cannot be reasonably estimated at this time. Although claims are inherently unpredictable, the Company is currently not aware of any other matters that would, individually or taken together, have a material adverse effect on its business, financial position, results of operations, or cash flows. As of June 30, 2026 and December 31, 2025, the Company has not accrued any material potential loss.
