Anthropic Reportedly Pays $3.4B for 1.7 GW of Gas Generators

What happened

The Financial Times reported on Nov 8 that Anthropic signed an agreement in late September to take over heavy-duty gas generator orders that San Antonio-based OnePWR Solutions had placed with Caterpillar about two years earlier. OnePWR needed financing to complete those orders; Anthropic had originally planned to buy electricity from OnePWR and instead took over the equipment orders.

The deal is worth about $3.4 billion and includes the engineering and construction capability needed to install the equipment; it does not include acquiring OnePWR itself, and no employees moved to Anthropic. The Financial Times called it the largest known single purchase of power-generation equipment by an AI lab. Investment bank Piper Sandler lists a September $3.4 billion transaction on its website: the sale of OnePWR's power generation platform to an unnamed frontier AI lab.

Anthropic and OnePWR did not respond to requests for comment. Reuters reported the agreement on Nov 8 and said it could not independently verify the Financial Times report. The generators' deployment sites and operating schedules have not been disclosed.
