Anthropic Signs $45 Billion Lease with NScale for AI Compute Capacity

Anthropic is set to lease a data center from NScale in a deal valued at $45 billion, further establishing itself as a major player in the AI compute landscape. This agreement adds to Anthropic's previous commitments, including a $19 billion lease with TeraWulf and a potential $16.1 billion deal with Riot Platforms, bringing its total compute commitments to over $150 billion by mid-2026.

The strategic move reflects Anthropic's intention to reduce reliance on traditional cloud providers like Amazon Web Services, instead opting for dedicated physical infrastructure that it can control. This approach aims to provide the necessary computational power for training and running inference on its Claude AI models.

NScale, founded in 2024 as a spinoff from a crypto mining company, has pivoted to focus on AI infrastructure. The company has quickly gained traction, raising $2 billion in a Series C round and acquiring significant compute capacity across various locations. NScale is categorized as a “neocloud” provider, specializing in high-density AI compute solutions.

The increasing demand for GPU capacity, coupled with global supply constraints, has led companies like Anthropic to secure partnerships with infrastructure providers like NScale, TeraWulf, and Riot Platforms. These companies, originally rooted in crypto mining and power generation, are now essential to the AI economy, leveraging their expertise in power management and thermal solutions.

New Developments in Anthropic's AI Compute Capacity

• Nscale has signed a $45 billion, six-year contract with Anthropic to provide AI computing services.
• The computing services will utilize Nvidia's next-generation Vera Rubin chips.
• The deployment of these chips is scheduled to begin in late 2027.
• The deal's power footprint is approximately 460 megawatts, enough to power around 345,000 American homes.
• Nscale also has a prior commitment with Microsoft for up to 1.35 gigawatts of Vera Rubin systems at the same site.
• Nscale plans to integrate between 100,000 and 130,000 Vera Rubin GPUs across its European operations.
• The Vera Rubin architecture is designed as a cohesive supercomputer system, targeting frontier AI needs.
• Anthropic is reportedly preparing to go public, making this computing capacity a strategic move for investor confidence.
• The focus on agentic AI workloads indicates a shift towards more complex, compute-intensive tasks.
• Nscale's commitments suggest the Monarch Compute Campus could consume over a gigawatt of power, nearing the output of a nuclear power plant.
