Anthropic Just Paid $9 Billion to Rent a Bitcoin Miner's Power Grid

Bitcoin miners are becoming AI’s new landlords, and Anthropic just signed the biggest lease yet. Claude developer struck a $9.1 billion deal with Riot Platforms for 191 megawatts of computing capacity at Riot’s Rockdale, Texas campus — enough electricity to power roughly 143,000 homes. The deal runs through 2048, making it one of the longest infrastructure commitments any AI company has ever made.

The Deal Terms Tell a Bigger Story

Riot Platforms disclosed the contract in a regulatory filing without naming the customer, referring only to a “leading frontier AI” company. Anthropic is the counterparty, and RIOT shares immediately jumped over 25% in overnight trading.

The contract’s structure reveals how seriously Anthropic takes long-term infrastructure planning. The base agreement covers 20 years through June 2048, but includes two five-year extension options that could stretch the relationship to 2058 and push the total contract value to $16.1 billion. That’s not a stopgap measure — it’s a multi-decade bet on the physical infrastructure needed to train and run frontier AI models.

The 20-year duration is the most telling detail. Cloud computing contracts typically run 3-5 years, with shorter commitments preferred as technology evolves rapidly. Anthropic locking in for two decades signals either extreme confidence that the location’s power and cooling infrastructure will remain relevant, or such intense competition for available capacity that they’re willing to overpay on time commitment to secure supply.
