Anthropic to rent AI computing power from Nscale for $45 billion, source says

Anthropic is set to spend $45 billion to rent AI cloud computing capacity from Nscale’s West Virginia data center campus, according to a person familiar with the matter. The six-year agreement, which represents roughly 460 megawatts of power capacity, comes as the AI startup prepares for a major initial public offering.

The deal underscores Anthropic’s aggressive push to secure computing power to meet anticipated demand for products such as its AI coding tool, Claude Code. Nscale, a cloud infrastructure provider, will deploy Nvidia’s new Vera Rubin chips to support Anthropic’s computing needs, the person said.

Anthropic has been spending heavily on GPUs and other computing capacity, as well as on model training, inference, and hiring. The company is projecting 2028 revenue of approximately $190 billion to $200 billion, far exceeding its $47 billion revenue "run rate," Reuters reported exclusively earlier this month.

The announcement follows a series of large-scale compute commitments by Anthropic. In July, Advanced Micro Devices revealed plans to sell Anthropic tens of billions of dollars’ worth of AI servers while investing up to $5 billion in the Claude developer. Additionally, in its IPO filing, SpaceX said Anthropic had agreed to pay it $1.25 billion per month through May 2029 for compute capacity that includes both of SpaceX’s AI training data center clusters, Colossus and Colossus II.

Anthropic declined to comment on the Nscale deal. Bloomberg News first reported the development earlier on Wednesday.

The agreement highlights the intensifying competition among AI developers to lock in large-scale infrastructure and energy resources, as demand for advanced model training and inference continues to outpace supply. For Nscale, the contract represents a major validation of its role as a provider of dedicated AI compute infrastructure in the U.S. market.
