Anthropic has agreed to pay about $3.4 billion for 1.7 gigawatts of gas-fired generators, the Financial Times reported Sunday, and despite headlines saying it “buys power,” what it bought is a stalled purchase order that someone else could not finance.
- The seller is OnePWR Solutions of San Antonio, which ordered the heavy-duty Caterpillar generators about two years ago and needed financing to complete the purchase, according to the FT’s account as relayed by Investing.com.
- Anthropic first planned to become a OnePWR customer, then took over the equipment orders instead. The commitments were secured in late September.
- The package includes the engineering and construction needed to install the machines. Anthropic did not acquire OnePWR, and none of its staff moved over.
- Not established: Anthropic and OnePWR did not respond to requests for comment, Reuters could not verify the report, and nobody has named a single site where these machines will run.
Everything above rests on one FT report citing one person familiar with the matter. We are treating it as unconfirmed, and so should you.
The headline on the Bloomberg version says Anthropic buys power for AI data centres. It does not. Nobody has bought a single kilowatt-hour. A generator is a large metal box that turns gas into electricity once someone supplies the gas, the land, the air permit and the crew, and none of those four appear in anything published so far.
Here is the number nobody printed. Divide $3.4 billion by 1.7 million kilowatts and you get $2,000 per kilowatt. Because the price also covers engineering and construction, that is not a clean equipment price, and we have not found a published benchmark we would trust to compare it against. Treat it as a ratio to hold the next disclosure up to, not a verdict.
The detail the coverage walked past is who could not pay. OnePWR held the Caterpillar orders for two years and could not close the purchase. Anthropic could, which tells you less about the generators than about who still has access to cheap money for physical things.
That matters because the same reporting says Blackstone has warned investors that Anthropic might receive a junk credit rating rather than the investment-grade one previously expected, while an IPO is being prepared for as early as this month. Reuters reported in September that Anthropic expects to spend more than $500 billion over the next decade on infrastructure. A $3.4 billion generator order is under one percent of that figure, which is how a deal this size ends up as a side item.
Other labs have started doing this too. The same report says xAI bought mobile gas turbines for $2 billion earlier this year and that Alphabet bought the energy developer Intersect late last year. The pattern is plain: the grid cannot deliver on the schedule the model builders want, so the model builders are becoming power companies.
That is their call to make. Ours is that a company building its own gas fleet owes the public the sites and the air permits before it owes them a prospectus. The House already voted 417 to 3 to make data centers pay for their own power, in a bill that requires nothing, so the only disclosure that will reach a neighbor of one of these machines is the permit notice. Anthropic should say where the 1.7 gigawatts goes and publish what those machines will emit.
Watch for three things: Anthropic confirming or denying the FT’s account, the first named site, and the first air permit filing with its name on it. Until one of them appears, the biggest generator purchase by an AI lab on record is a number with no address.
