Anthropic bought $3.4 billion in commitments for 1.7 gigawatts of heavy-duty gas-fired generators in late September, according to the Financial Times. The reported deal with San Antonio-based equipment supplier OnePWR Solutions includes access to existing Caterpillar orders and the engineering and construction capabilities needed to install the machines.

The FT describes it as the largest known single purchase of power-generation equipment by an AI lab. Anthropic and OnePWR declined to comment to the newspaper. Source
Old orders, new customer
OnePWR ordered the Caterpillar generators about two years ago but needed financing to complete the purchase, the FT reports, citing a person familiar with the matter. Anthropic initially planned to become a OnePWR customer, then opted to take over the equipment orders instead. Source
Anthropic didn’t buy OnePWR itself, and none of the supplier’s employees transferred, according to the FT. Source
The FT says the engines were ordered before prices surged and are available in the near term and over the next two years. With manufacturing lead times stretching years into the future, a two-year-old purchase order suddenly looks like a luxury item. Source
AI developers typically rely on utilities and specialist power companies for electricity, the FT notes. Taking over existing generator orders gives Anthropic more direct control over one scarce part of that infrastructure. The AI shopping list has become impressively industrial. Source
Equipment isn’t electricity on tap
The reported 1.7 gigawatts describes the generating capacity covered by the equipment commitments—not a confirmed fleet already installed and producing power. Source
The Next Web, which followed the FT’s report, explicitly says it has not independently confirmed the deal. Deployment locations remain undisclosed, and neither report establishes when the generators will begin operating.
