Anthropic Signs Another $9.1 Billion Compute Deal as Bitcoin Miner Riot Pivots to AI Data Centers, Sending Shares Up 25% After Hours

This major deal further accelerates Riot's transition from a Bitcoin miner to an AI data center service provider. Data shows that Riot's second-quarter data center business revenue reached $23.2 million, including 25 megawatts of deployed compute capacity from AMD (AMD), with another 25 megawatts under construction. Combined with the 191-megawatt deal signed with Anthropic, Riot's currently contracted data center capacity reaches 241 megawatts, corresponding to an expected contract revenue of approximately $9.8 billion.

For Anthropic, this marks its third consecutive large-scale compute procurement in recent months. In May this year, the company agreed to pay SpaceX (SPCX) nearly $45 billion to secure compute resources; last month, it signed a six-year, $10 billion deal with cloud infrastructure startup Volta.

In just three months, Anthropic has locked in over $60 billion in total compute contracts. This is aimed both at ensuring that its compute supply over the next decade remains unconstrained and at stockpiling resources to engage in long-term competition with rivals such as OpenAI and Google (GOOGL).
