CoreWeave wins Anthropic deal

CoreWeave said on April 10 that Anthropic signed a multi-year deal to run Claude on CoreWeave’s cloud, with new capacity coming online later in 2026. (coreweave.com) CoreWeave said Anthropic will use its platform to develop and deploy the Claude family of models at production scale. Bloomberg reported the capacity will span multiple United States data centers and use several Nvidia chip architectures. (businesswire.com) (bloomberg.com) Investors pushed CoreWeave shares higher after the announcement. CNBC reported the stock rose 11% on April 10, a day after Meta expanded its own CoreWeave commitment by another $21 billion through December 2032. (cnbc.com) (investors.coreweave.com) CoreWeave rents out the computing power behind artificial intelligence systems, mainly large clusters of Nvidia graphics processing units, which are the chips used to train models and answer user prompts. Anthropic builds Claude, a chatbot and application programming interface business that needs more of that capacity as usage grows. (coreweave.com) (anthropic.com) The deal lands days after Anthropic disclosed a separate infrastructure expansion with Google and Broadcom for multiple gigawatts of tensor processing unit capacity starting in 2027. That shows Anthropic is lining up more than one supplier as demand for Claude rises. (anthropic.com) For CoreWeave, the contract adds to a fast-growing backlog. The company said on February 26 that revenue backlog reached $66.8 billion at the end of 2025, up 342% from a year earlier. (investors.coreweave.com) (s205.q4cdn.com) CoreWeave has been public for just over a year. Its investor relations site says the company listed on Nasdaq in March 2025, after an offering that CNBC reported priced at $40 a share. (investors.coreweave.com) (cnbc.com) The company is also spending heavily to add more capacity. CNBC reported on April 9 that CoreWeave paired the expanded Meta agreement with plans to raise $3 billion in fresh debt, and separate March financing reports said it closed an $8.5 billion facility for infrastructure expansion. (cnbc.com) (markets.financialcontent.com) By the end of April 10, investors were treating the Anthropic and Meta announcements as evidence that the market for rented artificial intelligence computing is still tightening. CoreWeave’s next test is turning those long-term contracts into delivered capacity and revenue. (cnbc.com) (investors.coreweave.com)
