Anthropic signs $1.25B/month data center lease deal with xAI for 300MW Colossus I facility
Type: Supply Agreement · Technology: Data Center · Country: United States · Capacity: 300 MW · Value: $1.25B · Announced: 2026-05-22
Anthropic entered a three-year data center lease agreement with xAI for exclusive access to the 300MW Colossus I facility at a rate of $1.25 billion per month. The deal includes a mutual termination clause allowing either party to exit with 90 days' notice, providing flexibility amid evolving AI compute demands. Colossus I represents xAI's first operational data center, with the company having invested $12.7 billion in AI infrastructure during 2025 and an additional $7.7 billion in Q1 2026. Satellite imagery from January 2026 reportedly showed cooling equipment supporting 350MW capacity despite xAI's IPO documents claiming 1GW 'nameplate compute draw' from installed GPUs. The facility's actual utilization remains unclear as Grok, xAI's own AI platform, has experienced declining usage and staff departures.
