CoreWeave stock rose significantly after announcing a 6.3 billion dollar agreement with Nvidia to sell unsold cloud capacity through 2032. Shares initially jumped over 9 percent but late dropped following criticism from Kerrisdale Capital, which argued that CoreWeave's valuation is driven by hype and debt rather than innovation. They highlighted heavy dependence on a few customers and set a fair value target of ten dollars per share. The company closed the day with a gain of nearly 8 percent.
