CoreWeave<\/a> announced Friday that it has entered a multi-year agreement with Anthropic<\/a> to power its Claude artificial intelligence<\/a> models as demand for infrastructure continues to climb. <\/p>\n Shares of the neocloud climbed about 4% following the news.<\/p>\n “With the addition of Anthropic, nine of the leading ten AI model providers now leverage CoreWeave’s platform, reflecting the growing demand for infrastructure that can support AI at scale,” CoreWeave<\/a> said in the announcement.<\/p>\n The deal comes one day after Meta<\/a> committed to spending an additional $21 billion<\/a> with the AI cloud provider. The deal adds to a prior $14.2 billion commitment<\/a> announced in September.<\/p>\n CoreWeave declined to disclose the value of the Anthropic deal. The cloud provider told CNBC that of the top ten foundational AI models, Elon Musk<\/a>‘s xAI is the one company they do not yet work with.<\/p>\n According to the announcement, the Anthropic deal will focus initially on a “phased infrastructure roll-out,” with the potential to expand. <\/p>\n CoreWeave operates data centers with hundreds of thousands of the Nvidia<\/a> graphics processing units that power AI models. While hyperscalers are building out their own data centers, major companies including Microsoft<\/a>, OpenAI and Google<\/a> also use infrastructure from CoreWeave to meet the soaring demand.<\/p>\n Anthropic’s Claude and its AI-powered coding assistant Claude Code have exploded in popularity this year. Anthropic said Monday that its annual run rate<\/a> topped $30 billion, up from $9 billion at the end of 2025.<\/p>\n Stock Chart IconStock chart icon CoreWeave year-to-date stock chart.<\/p>\n![\"hide](\"https:\/\/static-redesign.cnbcfm.com\/dist\/a54b41835a8b60db28c2.svg\")
