Bitcoin miner Riot Platforms has signed a $9.1 billion, 20-year data center lease with a top AI lab, identified as Anthropic. The contract covers 191 megawatts of critical IT capacity at the Rockdale campus in Texas.
Key Takeaways
- 20-year lease worth roughly $9.1 billion in initial revenue, up to $16.1 billion if both five-year extensions are exercised
- First 96 MW expected in December 2027, the rest in June 2028; the tenant brings its own servers and chips
- Riot Platforms now holds 241 MW of contracted critical IT capacity, cementing its pivot from Bitcoin mining to AI hosting

Riot Platforms disclosed the contract alongside its quarterly results, describing the tenant only as one of the world’s leading frontier AI labs. Industry reporting identifies that tenant as Anthropic, whose infrastructure strategy matches the profile of the lease point by point.
The numbers set the scale. The lease runs 20 years, through June 2048, and is expected to generate approximately $9.1 billion over its initial term. Two five-year extension options, at the tenant’s election, push the total potential value to $16.1 billion. Riot lays out the terms in its second-quarter results announcement.
The delivery schedule is aggressive for a build of this size. The first 96 MW are slated for December 2027, with the remainder following in June 2028. At 191 MW of critical IT capacity, the site draws roughly the power of 143,000 homes.
The division of labor follows the build-to-suit colocation playbook. Riot constructs the facility to the tenant’s specifications and provides the building, power connections, cooling and operations. The tenant supplies its own servers and AI chips, the single heaviest line item in the whole project.
Keeping the tenant unnamed is a choice, not an oversight. A lab that publicizes its own future capacity hands rivals a card in a race where every available megawatt is negotiated years ahead. The structure lets the miner publish the numbers while the customer stays out of frame.
Rockdale joins a Texas map already crowded with AI infrastructure, where Amazon’s giant data center is on track for a CO2 record. The state keeps winning these campuses for a familiar equation: land, grid access and fast permitting.
Bitcoin mining recycles itself into an AI landlord
For Riot, the deal formalizes a strategic mutation. The quarter shows $174.2 million in revenue, up 14% year over year, with $113.7 million from Bitcoin mining and $23.2 million from the data center segment. The company still posted a $237 million net loss.
The gap between those two revenue lines tells the sector’s story. Mining stays volatile and hostage to the Bitcoin price, while a 20-year AI hosting lease converts megawatts into contractual rent. Riot models the lease’s average annual contribution at $365 to $411 million in net operating income.
With this agreement, Riot holds 241 MW of contracted critical capacity, including a separate lease with AMD, worth close to $9.8 billion under initial terms. The company is also working to convert a letter of intent at its Corsicana site, a one-gigawatt prize, into a formal lease.
Part of the quarterly loss traces back to that transition. Converting a mining site into a facility that meets a frontier lab’s standards means heavy spending committed long before the first rent check arrives. Investors reacted to the lease announcement rather than to the accounts themselves.
The pattern reaches well past Riot. Miners own exactly what AI labs lack: energized, grid-connected, operated sites. Hosting AI hands these companies a second life that is far more predictable than hashing blocks.

Anthropic’s compute race shifts into a higher gear
The lease extends a methodical accumulation on Anthropic’s side. In early August the lab locked in $10 billion of compute from cloud startup Volta, and it is assembling its own team dedicated to an in-house AI chip. The logic is a portfolio: multiply suppliers so no single one holds leverage.
Renting shell capacity from a miner adds a new string to that bow. Anthropic keeps control of its servers and chips while outsourcing concrete, power and cooling. The structure secures 2027 capacity without sinking capital into a self-build.
The user-side impact arrives at delivery time. Model availability, API rate limits and peak-hour queues all trace back to megawatts like these. Each tranche that comes online feeds enterprise usage growth, the segment Anthropic has been funding through record raises since its Series H.
For competitors, the signal cuts both ways. Rival labs watch twenty years of a scarce resource get locked away, and listed miners watch a business model get validated with a ten-figure contract. The next deals of this kind will price higher, and close faster.
The lease term says something about Anthropic’s own math. Committing through 2048 to infrastructure designed around today’s chips is a bet that compute demand outlives several generations of models, well past the current release cycle.
Execution risk is the caveat that remains. A delivery slip in 2027 would cost capacity at the worst point of the cycle, and Riot’s net loss is a reminder that turning a miner into a data center operator is not automatic. The contract is signed, and the clock is running.
