Anthropic Strikes $9.1 Billion AI Cloud Deal With Riot Platforms to Expand Claude Computing Capacity

Anthropic has struck a $9.1 billion, 20-year computing deal with Riot Platforms Inc. to expand capacity for its Claude AI models. The agreement covers 191 megawatts of IT capacity at Riot’s Rockdale, Texas campus, enough to power roughly 143,000 homes. 

Riot Platforms shares surged over 25% in after-hours trading Monday, August 10, 2026, after Bloomberg confirmed Anthropic as the previously unnamed customer.

Inside the Terms of Anthropic’s Riot Platforms Deal

Riot (NASDAQ: RIOT) Platforms disclosed the agreement Monday without initially naming its customer, calling it a deal with a “leading frontier AI lab.” The contract runs through June 2048.

• The deal includes two five-year extension options, potentially raising total value to $16.1 billion.
• Delivery will be phased, with the first 96 megawatts targeted for December 2027.
• Riot expects the full 191 megawatts to be operational by June 2028.

Riot secured a $573 million interim financing facility from Morgan Stanley to cover initial development costs. The company is still finalizing a separate investment-grade credit backstop for the project.

Why Anthropic Is Racing to Lock Down Computing Capacity

Anthropic’s Riot Platforms agreement fits a broader pattern of aggressive infrastructure deals signed over recent months. Surging customer demand for Claude has repeatedly outpaced available computing supply.

• Anthropic recently signed a $10 billion deal with infrastructure startup Volta Infra Holdings.
• In May 2026, Anthropic agreed to buy nearly $45 billion in computing from Elon Musk’s xAI.
• Anthropic also committed $30 billion toward Microsoft Azure compute capacity, with an option scaling to one gigawatt.

That Microsoft agreement notably netted Anthropic $15 billion in combined investment from Microsoft and Nvidia in return, alongside continued use of Amazon as its primary cloud and training provider.

Riot Platforms’ Transformation From Bitcoin Miner to AI Infrastructure Player

Riot Platforms built its original business around Bitcoin mining before pivoting toward AI data center services. This deal marks its second major computing customer win in 2026.

• Riot signed an earlier deal with Advanced Micro Devices Inc. (AMD) back in January 2026.
• The company completed delivery of an initial 25 megawatts to AMD on schedule and on budget.
• Combined, Riot’s AMD and Anthropic leases now total 241 megawatts of contracted capacity.

CEO Jason Les said these two agreements represent approximately $9.8 billion in combined long-term, contracted revenue with major AI ecosystem players.

Woah, $RIOT announced a $9.1B deal with Anthropic, with a possible contract extending to $16.1B, over 20Y.$AMD also exercised its option to expand its existing deal with Riot. (And they still have another 1 GW campus they have LOI with for a tenant)

Riot’s Second-Quarter Results Show the Financial Picture

Riot Platforms reported its Q2 2026 earnings the same day as the Anthropic deal disclosure. Results showed a mixed financial picture despite the infrastructure win.

• Q2 revenue rose 14% year-over-year to $174.2 million, beating estimates.
• Riot swung to a net loss of $237.2 million, compared with $219.4 million in net profit a year earlier.
• Riot’s Nasdaq-listed shares closed down 5.46% during Monday’s regular session before the after-hours surge.

That after-hours jump reflects investors pricing in the long-term revenue certainty this Anthropic contract provides, despite the quarter’s reported net loss.

What This Means for the Broader AI Infrastructure Race

Anthropic’s Riot Platforms deal underscores how crypto miners are repositioning themselves as critical AI infrastructure suppliers. Companies with existing power access and data center land now hold real leverage.

• Riot’s Rockdale, Texas campus offers established power infrastructure crypto miners already built out.
• This positions former mining operators as viable alternatives to traditional data center developers.
• Anthropic’s diversification across Amazon, Microsoft, xAI, Volta, and now Riot spreads its infrastructure risk.

This multi-vendor strategy suggests Anthropic is prioritizing supply security over consolidating with any single cloud provider.

Final Thoughts

This deal confirms Anthropic’s infrastructure strategy: diversify aggressively rather than bet on one supplier. Riot’s pivot from Bitcoin mining to AI computing now looks increasingly validated, with $9.8 billion in contracted revenue from two major AI players in just six months.
