Anthropic has signed a $9.1 billion data center deal with Bitcoin miner Riot Platforms at its Rockdale site in Texas, according to Bloomberg. The 20-year lease covers 191 megawatts, with the first phase of 96 megawatts set to become operational in December 2027.
Deal Terms
The lease at Riot's Rockdale facility runs for 20 years, with two extension options that could lift the total value to $16.1 billion. Riot will build the data center to the tenant's specifications, supplying the building, power connections, cooling, and daily operations. Anthropic is required to provide its own servers and AI chips. The first 96 megawatts are scheduled to come online in December 2027, followed by the remaining capacity in June 2028. Riot disclosed the contract alongside quarterly earnings but only described the customer as a 'leading frontier AI lab.'
Infrastructure Expansion
Anthropic's infrastructure push includes paying SpaceX an estimated $1.25 billion per month for the Colossus 1 data center through May 2029 and plans to deploy two gigawatts of AMD GPUs. Amazon is investing as much as $25 billion to build up to five gigawatts of Trainium capacity for the AI company. Additionally, gigawatts of TPU capacity from Google and Broadcom are set to come online starting in 2027, alongside a six-year, $10 billion deal with Volta Infra.
What's Next
Anthropic's closest rival, OpenAI, is also racing to secure data center capacity, with the two companies increasingly competing for power and capital. It remains unclear whether the massive buildout can outpace demand or whether cost pressures will eventually force consolidation.
