Anthropic signs about $45B compute deal with UK's Nscale

Nscale, founded only in 2024, will supply Anthropic with compute via Nvidia’s new Vera Rubin chip system — which combines six different chips working in concert and is considered the cutting edge of chip design — with capacity expected to start powering Anthropic’s services in late 2027, the source said. Nscale has already struck deals with Microsoft.

The deal, first reported by Bloomberg, spans six years and draws computing power from Nscale’s flagship data center in West Virginia. It’s the latest in a spree of compute partnerships Anthropic has signed over the past eight months as it races to scale capacity against rivals, most notably OpenAI.

Earlier this month, Anthropic signed a $10 billion deal with AI cloud startup Volta, founded in January, securing six years of cloud computing power from a data center in Norway. In July, the company signed a $5 billion compute deal with AMD. In May, it entered a large computing arrangement with SpaceX, drawing capacity from two of the company’s data centers and reportedly providing Anthropic with $1.25 billion worth of capacity each month. In April, Anthropic expanded its Amazon partnership to add 5 gigawatts of compute, and separately deepened its relationships with Google and Broadcom for additional power capacity that same month.

Anthropic isn’t alone in the scramble: Google, OpenAI, and Meta are all pursuing similarly aggressive compute buildouts.

Why it matters

The pace and size of Anthropic’s compute deals — six major agreements in eight months — signal that access to chips and power, not just model quality, is becoming the binding constraint in the AI race.
