CoreWeave and Anthropic have signed a multi-year agreement for the cloud infrastructure company to provide compute to support the development and deployment of Anthropic's Claude AI models, CoreWeave said Friday. The capacity will come online starting later this year.
Under the agreement, Anthropic will run workloads at production scale on CoreWeave's cloud platform. Infrastructure will be brought online in stages, the companies said, leaving room for the arrangement to grow beyond its initial scope. Financial terms were not disclosed.

The announcement pushed CoreWeave stock up more than 12% on Friday. CoreWeave told CNBC that among the top ten foundational AI model providers, Elon Musk's xAI is the one company it does not yet work with.
"AI is no longer just about infrastructure, it's about the platforms that turn models into real-world impact," CoreWeave CEO Michael Intrator said in a statement. "We're excited to work with Anthropic at the center of where models are put to work and performance in production shows up."
According to Bloomberg, the infrastructure will include a variety of Nvidia $NVDA chip architectures at U.S. data centers.
The deal arrives as Anthropic has been expanding its computing infrastructure on multiple fronts. The company signed an agreement with Google $GOOGL and Broadcom $AVGO for approximately 3.5 gigawatts of computing capacity built on Google's tensor processing units, with that capacity expected to come online starting in 2027. Separately, Anthropic reported this week that its annualized revenue has surpassed the $30 billion mark, a sharp jump from the roughly $9 billion pace it recorded at the close of 2025.
A separate memo OpenAI sent to investors this week characterized Anthropic as compute-constrained, putting Anthropic's 2025 capacity at 1.4 gigawatts versus OpenAI's own figure of 1.9 gigawatts. Anthropic pointed to its Google and Broadcom agreement when asked to respond.
The CoreWeave agreement adds to a busy stretch for the cloud provider. Just 24 hours before the Anthropic announcement, Meta $META had agreed to direct an additional $21 billion toward CoreWeave, layering on top of a $14.2 billion commitment the social media company had made previously.
