Anthropic agreed to pay $45 billion over six years for 460 megawatts of Nscale’s West Virginia Vera Rubin capacity, expected online in late 2027.

Anthropic agreed to pay Nscale $45 billion over six years for approximately 460 megawatts of AI-compute capacity at Nscale’s Monarch data-center project in West Virginia. The planned deployment will use NVIDIA Vera Rubin accelerators.

The first capacity is expected to become available in late 2027. The reported timing is prospective, and the source does not state that the 460 megawatts are currently operating.

The full Monarch campus is planned for approximately 1.35 gigawatts and a total investment of about $71 billion. Approximately $47 billion is expected to be spent on AI chips, while additional buildings are expected to begin providing compute capacity in 2028.

The project was previously expected to have Microsoft as a tenant, but Microsoft withdrew during the summer and Anthropic subsequently took the tenancy, according to the report. The source also reported separate Anthropic compute agreements with Fluidstack, Volta Infra and SpaceX valued at $50 billion, $10 billion and $45 billion, respectively.
