CoreWeave, Inc. (CRWV) closed at $125.06 on October 21, 2025, down 1.57%, with after-hours trading at $124.40 (-0.53%). The stock has experienced sharp declines since October 16, 2025, following a period of rapid gains and major partnership announcements. In October, CoreWeave signed a cloud capacity deal with Meta Platforms (up to $14.2 billion) and expanded its OpenAI contract (totaling $22.4 billion in 2025), reinforcing its leadership in AI infrastructure. Despite these wins, recent analyst commentary highlights valuation concerns and downward earnings estimate revisions, contributing to the pullback.
