Nscale signs $45B deal to deploy Nvidia’s Vera Rubin chips for Anthropic’s AI needs

A London-based AI infrastructure company most people haven’t heard of just locked in one of the largest cloud computing deals ever signed. Nscale has agreed to a $45 billion, six-year contract with Anthropic to provide computing services powered by Nvidia’s next-generation Vera Rubin chips at its Monarch Compute Campus in West Virginia. To put that dollar figure in perspective, it’s roughly the GDP of Latvia. And the deal’s power footprint is equally staggering: approximately 460 megawatts, enough electricity to run about 345,000 American homes. What Nscale is building The deployment of Nvidia’s Vera Rubin chips under this agreement is slated to begin in late 2027. The Vera Rubin architecture represents Nvidia’s successor to the current Blackwell/Grace platform, designed as a cohesive supercomputer system rather than a collection of individual GPUs bolted together. The platform features seven chips engineered to function as a unified AI supercomputer, specifically targeting the needs of frontier AI labs like Anthropic. Nvidia has pitched the architecture as delivering higher throughput per watt and lower costs per token compared to its predecessors. Nscale isn’t putting all its egg...
