CoreWeave Faces Securities Class Action Over AI Capacity Claims and Supplier Risks

Overview

• The lawsuit, filed in the U.S. District Court for the District of New Jersey as Masaitis v. CoreWeave, Inc., No. 26-cv-00355, names the company and certain executives under the Securities Exchange Act.
• The putative class covers purchasers of CoreWeave securities from March 28, 2025 through December 15, 2025.
• Plaintiffs allege CoreWeave overstated its ability to meet demand and downplayed the risk from reliance on a single third‑party data‑center provider, which was likely to affect revenue.
• Cited events include the Oct. 30, 2025 termination of the Core Scientific merger (share drop of more than 6%), Nov. 10–11 guidance cuts and CEO remarks (about a 16% decline), and a Dec. 15 Wall Street Journal report tied to additional losses of roughly 3%.
• Multiple plaintiff firms, including Robbins Geller, Bleichmar Fonti & Auld, Kessler Topaz, Rosen, Kirby McInerney, and Kahn Swick & Foti, are soliciting investors, and no class has been certified.
