Anthropic commits $45 billion in compute to Nscale

Six years of capacity lease, about 460 megawatts on the Nscale campus in West Virginia: the largest contract in the British company's order book, a few weeks before its IPO.

Anthropic has committed to spend $45 billion to rent computing power from Nscale, on the flagship site that the British company is developing in West Virginia. The commitment spans six years and represents approximately 460 megawatts, equivalent to the instantaneous consumption of approximately 345,000 U.S. households.

Nscale will rely on Nvidia's Vera Rubin chips, the first units of which must enter service by the end of 2027. This is the fourth major calculation commitment made public by Anthropic in recent months, after 50 billion with Fluidstack, 45 billion with SpaceX and 10 billion with Volta for a data centre in Norway.

For Nscale, this contract is the largest in an order book valued at $51 billion, and the argument that Goldman Sachs and JPMorgan will put forward to investors during the stock market introduction scheduled for September.
