Anthropic bought $3.4B of gas generators — the grid can't keep up

Anthropic has agreed to pay about $3.4 billion for 1.7 gigawatts of gas-fired generators to power its data centers, the Financial Times reported on November 8. The Claude maker took over generator orders that San Antonio-based OnePWR Solutions placed with Caterpillar about two years ago — without buying the company or taking on its staff.

The deal is a queue-jump, not a shopping trip. Power equipment has become one of the tightest bottlenecks in the AI build-out, and Anthropic's own IPO filing warns generators and turbines “must be ordered years in advance.” The package also covers the engineering and construction work to install the machines, though where they will go — and when — has not been disclosed.

The timing is awkward: Anthropic's filing says some planned data centers rely on dedicated on-site natural-gas generation, with fuel costs passed through without caps — and the report lands days after voters backed limits on AI data centers in 40 of 41 local ballot measures. Neither Anthropic nor OnePWR commented, and Reuters said it could not independently verify the report.
