CoreWeave published a multi-year agreement with Anthropic Friday to power its Claude AI models.

The deal comes one day after the AI cloud provider revealed a $21 billion expansion of its agreement with Meta.

CoreWeave now provides services to nine of the 10 leading AI providers, according to the firm.

CoreWeave stated Friday that it has entered a multi-year agreement with Anthropic to power its Claude artificial intelligence models as demand for infrastructure continues to climb.

“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 remarked in the announcement. This also touches on aspects of investors.

The deal comes one day after Meta committed to spending an additional $21 billion with the AI cloud provider. The deal adds to a prior $14.2 billion commitment revealed in September. Furthermore, experts in bull market note the continued relevance.

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’s xAI is the one organization they do not yet work with.

the Anthropic deal will focus initially on a “phased infrastructure roll, according to the announcement-out,” with the potential to expand.

CoreWeave operates data centers with hundreds of thousands of the Nvidia graphics processing units that power AI models. While hyperscalers are building out their own data centers, major companies including Microsoft, OpenAI and Google also leverage infrastructure from CoreWeave to meet the soaring demand.

CoreWeave, which went public last year, has taken out significant debt to finance its slew of AI deals.In debt on its balance sheet at the end of 2025, CNBC previously reported that the corporation held $21 billion, and added another $8.5 billion to fund recent infrastructure in March.

The firm revealed yesterday that it is raising $3 billion in fresh debt to fund its deal with Meta.

“We are focusing our energy on taking advantage of this generational opportunity to massively grow and expand our business,” CoreWeave CEO Mike Intrator noted Friday on CNBC’s “Squawk on the Street.”

“We need to have an opportunity to scale, and scaling is expensive,” Intrator added.

Anthropic’s Claude and its AI-powered coding assistant Claude Code have exploded in popularity this year. Anthropic commented Monday that its annual run rate topped $30 billion, up from $9 billion at the end of 2025.
