Riot Platforms Rockdale site (bitcoin mine turning into AI data center)
Riot runs one of the largest bitcoin mines in the US near Rockdale. It now rents space there to chip maker AMD for AI computing and plans to turn the whole 700-megawatt site into data centers.
Where things stand: Runs as a bitcoin mine; first AI space for AMD delivered in 2026; Riot plans to convert all 700 MW.
🕒 Latest update (May 1, 2026): AMD added 25 MW, for 50 MW in total.
