Anthropic leases $9.1B in data center capacity from bitcoin miner Riot

Anthropic is leasing data center capacity from Bitcoin miner Riot Platforms, covering 191 megawatts at Riot's Rockdale, Texas site and worth $9.1 billion, according to Bloomberg. Extension options could push the total value to $16.1 billion. The deal is part of a broader infrastructure push that also includes Amazon, SpaceX, and Google as partners.

Why it matters: Bitcoin miners already hold large amounts of built-out power infrastructure, so AI labs increasingly see leasing their sites as a faster route to capacity than waiting years for new grid connections. It underscores how power access, not chip supply, is now often the binding constraint on scaling AI compute.
