Anthropic’s $45B Nscale Compute Deal Signals a Bigger Race for AI Infrastructure

Anthropic has struck a deal worth around $45 billion with British cloud startup Nscale, Bloomberg reports. Under the six-year arrangement, the Claude maker will rent compute capacity from a data center in West Virginia. Starting late next year, Anthropic will use 460 megawatts of Nvidia’s coming Vera Rubin chip generation there, according to two people familiar with the matter.

The reported agreement comes as Anthropic moves quickly to secure compute ahead of an IPO planned for this fall. The company is also locking in capacity through deals with Amazon and SpaceX, plus a commitment to lease Google’s AI chips for more than $150 billion. It has also held early talks with Meta about a possible multibillion-dollar deal.

Nscale is preparing an IPO of its own and raised $2 billion in March at a valuation of $14.6 billion, led by Norwegian energy company Aker. The company says its planned 1.35-gigawatt data center in Mason County will cost $69 billion. The project is facing pushback from local residents.

The report highlights how access to power, chips, and data center capacity has become central to frontier AI competition. For Anthropic, the Nscale agreement would add another major infrastructure commitment around Claude. For Nscale, the deal would tie its growth plans to one of the most visible AI companies in the market.
