Riot Platforms Inks $9.1 Billion Data Center Lease Deal with Anthropic

Riot Platforms has secured a massive data center lease deal worth approximately $9.1 billion over 20 years with Anthropic, according to Bloomberg.

The contract covers 191 megawatts of capacity at Riot's Rockdale, Texas campus and runs through June 2048. The power generated by this lease could supply around 143,000 homes at once.

Riot's stock rose roughly 25% in after-hours trading once the deal's size became public, while shares closed down 5.46% during Monday's regular trading session.

The company has been shifting its focus from Bitcoin mining to AI hosting, with this lease being its second major AI infrastructure deal this year, following an earlier agreement with AMD in January 2026.
