Power Is the New Cloud: Inside Anthropic's $9.1B Data Center Deal with a Bitcoin Miner
On August 10, bitcoin miner Riot Platforms disclosed a 20-year data center lease with a leading frontier AI lab (Riot Platforms, 2026). The deal covers 191 megawatts of critical IT capacity at Riot’s Rockdale, Texas campus (CNBC, 2026). Bloomberg identified the tenant as Anthropic, citing people familiar with the matter (The Decoder, 2026). Neither company confirmed the name publicly. Riot declined to comment, and Anthropic did not respond (crypto.news, 2026).
The contract is expected to generate roughly $9.1 billion in revenue over the initial term, which runs through June 2048 (Riot Platforms, 2026). Two five-year extension options could push the total value to about $16.1 billion (CNBC, 2026). Riot shares jumped roughly 25% in after-hours trading once the deal’s size became public (Quartz, 2026).
What the deal actually is
Section titled “What the deal actually is”This is a colocation agreement, not a cloud contract. Riot builds the data center to the tenant’s specifications and provides the building, power connections, cooling, and operations (The Decoder, 2026). The tenant brings its own servers and AI chips (MLQ, 2026). The 191 MW is enough power for roughly 143,000 homes, per Bloomberg (The Decoder, 2026).
Delivery is phased. The first 96 megawatts go live in December 2027. The full 191 megawatts arrive by June 2028 (Riot Platforms, 2026).

Why a bitcoin miner is suddenly a data center developer
Section titled “Why a bitcoin miner is suddenly a data center developer”Riot is one of the world’s largest bitcoin miners and has owned its power assets for years (Data Center Dynamics, 2026). It controls more than 1,100 acres and 1.7 GW of power capacity across two Texas facilities (Data Center Dynamics, 2026).
The pivot began in January 2026 with Advanced Micro Devices. Riot signed a lease for an initial 25 MW, which it delivered on time and on budget, and a second 25 MW expansion is under construction (Riot Platforms, 2026). That AMD agreement can expand to a total of 200 MW at the campus (Data Center Dynamics, 2026).
The two leases give Riot 241 MW of contracted capacity and about $9.8 billion in long-term contracted revenue (Riot Platforms, 2026). CEO Jason Les called the lease “a defining moment in our evolution into a leading developer of large-scale data centers” (Riot Platforms, 2026).
The financials show the transition in progress. Q2 2026 revenue was $174.2 million, up 14% year over year, with data center revenue of $23.2 million (Riot Platforms, 2026). Riot still posted a net loss of $237.2 million for the quarter (Quartz, 2026). Miners across the sector are chasing the same pivot. Shares of peers IREN, Applied Digital, and TeraWulf moved higher on the news (Yahoo Finance, 2026).
Power is the new bottleneck
Section titled “Power is the new bottleneck”The deal gives Anthropic access to scarce, grid-connected power (CNBC, 2026). Miner campuses already own the hard part of the stack: land, substations, and interconnection rights. A frontier lab cannot wait years for a utility build.
Rockdale is one piece of a much larger Anthropic portfolio. The company is paying SpaceX an estimated $1.25 billion per month through May 2029 for the Colossus 1 data center and plans to deploy two gigawatts of AMD GPUs (The Decoder, 2026). Amazon is investing up to $25 billion toward up to five gigawatts of Trainium capacity (The Decoder, 2026). Gigawatts of Google and Broadcom TPU capacity come online starting in 2027, and a six-year, $10 billion contract with Volta Infra rounds out the portfolio (The Decoder, 2026). Bloomberg also reported a nearly $45 billion compute commitment to xAI in May (Quartz, 2026).
What this means for engineers
Section titled “What this means for engineers”- Power, not chips, now gates AI capacity. The scarce resource in this deal is 191 MW of interconnected electricity, not GPUs (CNBC, 2026). Capacity planning starts at the substation, not the rack.
- Colo economics are the new frontier. The landlord supplies shell, power, cooling, and operations. The tenant owns the compute (MLQ, 2026). Budget for hardware separately from facilities.
- Capacity lands in waves. 96 MW arrives in December 2027, and the rest lands six months later (Riot Platforms, 2026). Plan deployment as two campaigns, not one.
- Watch the miners. Bitcoin miners hold the interconnected power the AI buildout needs, and they are monetizing it as landlords (Data Center Dynamics, 2026).
