CoreWeave announced on April 10, 2026, that it has entered a multi-year agreement with Anthropic to provide infrastructure for Anthropic's Claude artificial intelligence models, amid rising demand for AI infrastructure. Following the announcement, CoreWeave's stock jumped more than 10% in trading, reflecting strong investor enthusiasm for the deal [1]. According to CoreWeave, this partnership means that nine of the leading ten AI model providers now utilize its platform, with Elon Musk's xAI being the only exception [1].
The Anthropic deal will begin with a phased infrastructure roll-out and has the potential for further expansion, although CoreWeave declined to disclose the financial terms of the agreement [1]. This news comes just one day after Meta committed to spending an additional $21 billion with CoreWeave, adding to a previous $14.2 billion commitment announced in September. To fund these deals, CoreWeave announced it is raising $3 billion in new debt, on top of $21 billion in debt held at the end of 2025 and another $8.5 billion added in March for infrastructure expansion [1].
CoreWeave operates data centers equipped with hundreds of thousands of Nvidia GPUs, supporting major AI companies such as Microsoft, OpenAI, and Google. CEO Mike Intrator emphasized the company's focus on scaling its business to meet generational opportunities in AI, noting that scaling is expensive and requires significant investment [1].
Anthropic's Claude and its AI-powered coding assistant Claude Code have seen rapid growth in popularity in 2026. Anthropic reported that its annual run rate reached $30 billion, up from $9 billion at the end of 2025, highlighting the accelerating adoption of its AI products [1].
CONCLUSION
CoreWeave's multi-year deal with Anthropic and Meta's expanded commitment have significantly boosted investor confidence, as evidenced by an 11% surge in CoreWeave's stock price. The company's aggressive infrastructure expansion and debt financing underscore its pivotal role in powering leading AI models. The market takeaway is that CoreWeave is rapidly scaling to meet soaring AI demand, positioning itself as a key player in the AI infrastructure space.
