Anthropic signs $9.1 billion data center deal with Bitcoin miner Riot Platforms
Anthropic locks in $9.1 billion data center deal with Bitcoin miner Riot Platforms. That’s according to Bloomberg, citing people familiar with the matter. Riot disclosed the contract a day earlier alongside its quarterly earnings but only described the tenant as a “leading frontier AI lab.”
The deal covers 191 megawatts at Riot’s Rockdale site in Texas, enough power for roughly 143,000 homes, according to Bloomberg. Riot will build a data center to the tenant’s specs, providing the building, power connections, cooling, and operations. Anthropic has to bring its own servers and AI chips. The lease runs 20 years, with two extension options that could push the total value to $16.1 billion. The first 96 megawatts are set to go live in December 2027, with the rest following in June 2028.
The deal adds to a growing list of Anthropic infrastructure commitments. The company is paying SpaceX an estimated $1.25 billion per month through May 2029 for the Colossus 1 data center and plans to deploy two gigawatts of AMD GPUs. Amazon is investing up to $25 billion and building up to five gigawatts of Trainium capacity with Anthropic. On top of that, gigawatts of TPU capacity from Google and Broadcom are coming online starting in 2027, and a six-year, $10 billion contract with Volta Infra rounds out the portfolio.
