Anthropic has finalized a six-year, $45 billion cloud computing agreement with AI infrastructure provider Nscale. Under the terms of the deal, Anthropic will secure approximately 460 megawatts of dedicated computing capacity at Nscale's Monarch data center development in West Virginia, scheduled to come online in late 2027.
The deployment will be powered by Nvidia's upcoming Vera Rubin architecture, providing compute bandwidth for next-generation foundation model training and enterprise inference across Anthropic's Claude ecosystem.
Infrastructure Allocation and Campus Scope
The 460-megawatt commitment covers the first of three planned facilities at Nscale's 1.35-gigawatt Monarch campus. The entire campus development carries an estimated capital cost of $71 billion, including on-site energy generation infrastructure and $47 billion allocated specifically for AI accelerator silicon.
Key parameters of the infrastructure contract include:
- Contract Value and Duration: $45 billion across a six-year operational term.
- Power Capacity: 460 MW dedicated draw, equivalent to the continuous power demand of roughly 345,000 residential homes.
- Hardware Profile: Multi-node clusters built on Nvidia Vera Rubin platforms.
- Campus Scale: Anchor tenancy on a multi-phase 1.35 GW campus with subsequent data halls scheduled for 2028 deployment.
Capital Strategy and Compute Diversification
The agreement with Nscale represents the latest in a sequence of multi-billion-dollar compute commitments executed by Anthropic as it scales capacity ahead of an anticipated initial public offering. In recent months, Anthropic has structured large-scale capacity agreements across diverse cloud operators, including a $50 billion commitment with Fluidstack, a $45 billion arrangement with SpaceX, and a $10 billion lease with Volta Infra Holdings.
For Nscale, securing Anthropic as an anchor tenant provides long-term contracted revenue as the company prepares its own public listing. The substantial scale of long-term power purchase agreements underscores the accelerating capital intensity required to maintain competitive frontier model development.
