Anthropic is reported to have bought 1.7 gigawatts of gas generators. Nobody has confirmed it
The Financial Times, as reported on 8 November, says Anthropic agreed in late September to pay about $3.4 billion for 1.7 gigawatts of Caterpillar generators that OnePWR had already ordered. It did not buy the company. Neither side has confirmed the deal. A generator on order is not a megawatt on a meter.

Bloomberg, citing the Financial Times on 8 November, reported that Anthropic has agreed to pay $3.4 billion for gas-fired generators. The account says the company, in late September, took commitments for 1.7 gigawatts of heavy-duty machines from OnePWR Solutions, a supplier in San Antonio, without buying OnePWR itself. Anthropic had first meant to buy the electricity. It took over OnePWR’s existing orders with Caterpillar instead. The FT, in that telling, called it the largest known single purchase of power-generation equipment by an AI lab. “Known” means known to the paper. It is not a register.
Later accounts add the queue, and they add the silence. OnePWR is said to have placed the Caterpillar orders about two years ago, before later price rises, and to have needed the money to complete them. The generators are described as expected within the next two years, with OnePWR still doing the engineering to install them. Dividing $3.4 billion by 1.7 million kilowatts gives $2,000 a kilowatt. That is arithmetic on the two reported figures. It is not a price in a Caterpillar release. Neither Anthropic nor OnePWR has confirmed the deal. A generator that has changed buyer is still a generator that has not been fuelled.
Caterpillar’s own quarter, reported on 29 October, already put the rise in Power Generation sales mainly on turbines and large engines, primarily in data-centre applications. That was a sales line. This, if the paper is right, is a named customer stepping into someone else’s order. The two are not the same document.
