A bitcoin miner just signed the biggest lease of its life — 20 years, 191 megawatts, and Anthropic on the other side of it
Riot Platforms disclosed to the SEC on 10 August that it had signed a 20-year lease at its Rockdale, Texas campus with a tenant it described only as a leading frontier AI lab: 191 megawatts of critical IT capacity, and roughly $9.1 billion of base contract revenue through June 2048. Two five-year extension options could take the total to about $16.1 billion. Bloomberg identified the tenant as Anthropic, citing people familiar with the matter; neither company has confirmed it on the record. The first 96 megawatts are due to come online in December 2027 and the full 191 by June 2028, using an interconnection Rockdale has already had approved. Riot shares rose about 17% on the news, and chief executive Jason Les said on Monday's earnings call that the company had also signed a letter of intent with an unnamed tenant for its one-gigawatt site at Corsicana.
