A bitcoin miner best known for chasing block rewards in the Texas heat just signed one of the largest infrastructure commitments an AI company has ever handed a crypto operator. On Tuesday, Riot Platforms disclosed a 20-year agreement worth roughly $9.1 billion to supply computing capacity to "a leading frontier AI lab," a customer identified in Bloomberg's reporting as Anthropic. Investors did not wait for confirmation: RIOT shares surged more than 20% before U.S. markets opened, and jumped as much as 25% in after-hours trading the night before.
The deal is a milestone in a quiet but accelerating shift, in which the power-hungry sites built to mint digital coins are being retrofitted to train and serve large language models instead.
The terms
Under the co-location agreement, Riot will deliver 191 megawatts of critical IT capacity at its Rockdale, Texas campus, the sprawling facility that once anchored the company's bitcoin operation. The base term runs through June 2048 and is expected to generate approximately $9.1 billion in contracted revenue. Two five-year extension options could lift the total to $16.1 billion if the tenant exercises both.
Deployment is phased. Riot expects to bring an initial tranche online in December 2027, with the full 191-megawatt buildout completed by June 2028. The company projects the base term alone will produce between $7.3 billion and $8.2 billion in cumulative net operating income.
To fund the early construction, Riot secured a $573 million facility from Morgan Stanley while it works to finalize longer-term financing. It is also drawing down its own balance sheet: the company's bitcoin holdings fell from 15,680 BTC to 11,380 BTC over the second quarter, a reduction of 4,300 coins, as it sold production to bankroll the pivot.
From block rewards to AI leases
Riot's chief executive framed the announcement as a turning point for a company still carrying "Platforms" in a name that once meant mining rigs.
"Today's announcement of a landmark 20-year, 191-megawatt data center lease with a leading frontier AI lab marks a defining moment in our evolution into a leading developer of large-scale data centers," CEO Jason Les said in a statement. He added that it "builds directly on a strong second quarter, in which we completed delivery of the initial 25 megawatts to AMD on time and on budget."
That AMD reference matters. This is not Riot's first AI tenant. The Anthropic-linked deal follows an earlier lease with the chipmaker, bringing contracted AI capacity at Rockdale to 241 megawatts. "In just over six months, Riot has now executed leases totaling 241 megawatts of capacity, representing approximately $9.8 billion of long-term, contracted revenue with two of the most important companies in the AI ecosystem," Les said.
The logic behind the pivot is straightforward. Bitcoin mining revenue is volatile, tied to the coin's price and to escalating network competition. Riot's second-quarter mining revenue slid to $113.7 million even as total revenue rose 14% to $174.2 million, buoyed by a nascent $23.2 million data center line. A two-decade lease with a well-capitalized AI customer offers something mining never could: predictable, contracted cash flow.
Why the crypto-to-AI trade works
The deeper story is about physical infrastructure. Frontier AI labs are bottlenecked not by ideas but by megawatts, and by the years it takes to secure them. Building a new data center from a bare field means fighting for grid interconnection queues, permitting, substations, transformers and cooling, a process that can stretch well beyond the pace at which AI demand is compounding.
Bitcoin miners already solved that problem for a different purpose. They control large parcels of land with energized power capacity, established grid connections and cooling systems built to dissipate enormous heat loads. Riot's Rockdale campus alone has roughly 700 megawatts of developed, energized capacity plus fiber and electrical infrastructure the company says can be repurposed for high-density computing. That head start lets miners serve power-hungry customers faster than a greenfield developer starting from scratch.
The pattern is not unique to Riot. Just a week earlier, Anthropic signed a six-year, $10 billion computing contract with Volta Infra for capacity at a Norwegian site operated by bitcoin miner Bitdeer. Rivals including Cipher Mining, TeraWulf and IREN have struck their own AI infrastructure deals, converting mining sites into GPU-ready data halls.
For Anthropic, the arithmetic is about scale. The lab is racing to secure enough compute to train successive generations of its Claude models and to serve rapidly growing enterprise demand, and it is spreading those bets across multiple providers rather than depending on any single hyperscaler. Stacked against its recent Volta Infra agreement, the Riot deal signals a strategy of locking in long-dated, power-secured capacity wherever it can be found, including on sites that were mining bitcoin a year ago.
What to watch next
Three things bear watching. First, financing: Riot has a Morgan Stanley bridge, but the full buildout will require far more capital, and the terms of that raise will shape how much of the $9.1 billion flows to shareholders versus lenders. Second, execution risk: the December 2027 and June 2028 milestones are aggressive, and delivering nearly 200 megawatts of high-density AI capacity on time is a very different discipline than running mining rigs.
Third, the market's own ambivalence. Despite the initial pop, RIOT gave back much of its intraday gain, and AI-focused mining peers such as Cipher, TeraWulf and IREN remain more than 40% below their record highs amid a broader AI-sector selloff. The Riot-Anthropic deal has also fueled fresh speculation about an eventual Anthropic IPO, given the scale of the compute commitments the lab is now making public. Whether this deal marks the moment the crypto-to-AI trade matures, or the top of a hype cycle, will depend on whether the megawatts actually show up on schedule.
