TLDR Riot Platforms signed a 20-year data center lease worth about $9.1 billion, later reported to be with Anthropic The deal covers 191 megawatts of capacity at Riot’s Rockdale, Texas campus
Riot Platforms disclosed a new data center lease agreement on August 10, 2026. The company did not name its partner at first, calling it a “leading frontier AI” company.
Bloomberg later reported the counterparty is Anthropic, citing people familiar with the matter. Neither Riot nor Anthropic confirmed this directly.
The lease covers 191 megawatts of IT capacity at Riot’s Rockdale campus in Texas. That amount of power could run roughly 143,000 homes at once.
The contract runs through June 2048. Delivery happens in phases, with 96 megawatts due by December 2027 and the full 191 megawatts ready by June 2028.
Total contract revenue is expected to reach about $9.1 billion. Two five-year extension options could push that figure up to $16.1 billion.
Riot secured a $573 million interim financing facility from Morgan Stanley to fund early development. The company is still finalizing a separate credit backstop for the rest of the buildout.
Riot’s stock closed down 5.46% during Monday’s regular trading session. Shares then rose about 25% after hours once the deal’s scale became clear, trading near $24.30 to $24.40.

This is Riot’s second major AI infrastructure deal this year. The company signed an earlier lease with AMD in January 2026.
CEO Jason Les linked both deals together in the company’s earnings statement. He said Riot has now signed leases totaling 241 megawatts, worth close to $9.8 billion in contracted revenue.
Riot began moving away from Bitcoin mining toward AI data centers last year. The company started this shift before signing its AMD lease.
This is not the company’s first pivot. Riot originally made diagnostic machinery for the biotech industry under the name Bioptix before it moved into Bitcoin mining years ago.
Other mining companies are making similar moves. Firms including Core Scientific, IREN, Applied Digital, TeraWulf, and Hut 8 are pursuing AI and high-performance computing deals of their own.
Anthropic has been securing computing capacity from several providers. The company already works with Amazon Web Services, Google Cloud, and Microsoft Azure, and has separate deals with Volta Infra and xAI.
Riot announced the lease alongside its second-quarter earnings. Total revenue rose 14% to $174.2 million, with data center revenue reaching $23.2 million.
Bitcoin mining revenue for the quarter came in at $113.7 million. The company mined 1,587 BTC and ended the period holding more than $1.2 billion in liquid assets.
Riot reported a net loss of $237.2 million, or $0.68 per diluted share. That compares with net income of about $219.4 million in the same quarter last year.
Retail sentiment toward Riot turned bullish after the announcement. Riot stock is up 53% year to date as of its last close.
