Riot Platforms signs 15‑year $28 billion AI data‑center lease with Anthropic

Riot Platforms announced a 15‑year lease of its entire Corsicana, Texas campus to AI lab Anthropic, valued at roughly $28 billion. The lease covers 910 MW of capacity, generates about $1.8 billion of annual rent, and costs Riot about $6 million per megawatt – roughly half the cost of a typical build. Riot plans to fund 80‑90% of the project with debt and does not expect to issue equity, while a $573 million bridge loan must be refinanced by Dec. 31.

The lease could lift Riot’s 2028 revenue to $1.75 billion, up from prior expectations of $1.21 billion. Investors will watch whether the company can refinance the $573 million bridge loan without a new equity raise, which would avoid dilution.
