Anthropic, the developer of the Claude AI models, has agreed to pay $3.4 billion for 1.7 gigawatts of heavy-duty gas-fired generators by taking over equipment orders placed by a Texas supplier, according to a report by the Financial Times.
Anthropic signed for the equipment in late September with OnePWR Solutions, a supplier headquartered in San Antonio, Texas. No AI lab is known to have made a bigger one-off purchase of generating equipment, according to the newspaper.
Anthropic did not buy OnePWR as a company. The deal did cover the engineering and construction capabilities required to install the generators, but none of OnePWR’s staff moved to Anthropic.
The machines themselves come from Caterpillar. OnePWR placed its generator orders with the U.S. manufacturer two years ago but needed financing to complete the purchase, according to the same person. Anthropic first intended to sign up as a OnePWR customer, then chose to take over the Caterpillar orders itself.
That structure sits somewhere between acquiring a whole company and simply buying hardware. It gives Anthropic engines that were ordered years earlier, before prices surged, and that can be delivered in the near term and over the next two years, the FT said.
Most AI developers buy their electricity through utilities or specialist power firms. Orders for turbines and generators have surged, though, and factories are quoting delivery times several years away, so cash-rich AI groups are bypassing middlemen to secure supply themselves, the report said.
Others in the sector have made similar moves. xAI, which is owned by Elon Musk’s SpaceX, spent $2 billion on mobile gas turbines earlier this year, and getting equipment directly has been crucial to bringing SpaceX’s large data centers online quickly. In December 2025, Google’s parent Alphabet agreed to acquire energy developer Intersect for $4.75 billion in cash plus the assumption of debt.
Intersect builds infrastructure that places data centers and other energy-intensive industries next to dedicated gas and renewable power generation, according to Alphabet’s announcement. Anthropic’s own ties to SpaceX run deep: it is a major customer, and its monthly payments to lease computing capacity from SpaceX are expected to reach $3.1 billion by the end of the year.
The generator deal fits a wider effort by Anthropic to control more of the infrastructure behind its operations. Its disclosed computing commitments now approach $900 billion and stretch to 2045. It has leaned heavily on partners to line up land, chips, data centers and power, paying extra to reserve capacity ahead of demand. Having its own generators puts more of that electricity supply in its hands.
Arash Nazhad, a managing director and head of clean energy and power at Stifel, said: “By owning some of their power infrastructure and having the capabilities in-house, companies believe they can better protect themselves against disruptions beyond their control”.
Anthropic filed its IPO registration statement on October 26. An amended filing submitted on November 2 showed $146.7 billion in liabilities and $95.6 billion in cash and cash equivalents as of September 30, 2026.
Earlier capacity deals show how those commitments built up. An April agreement with Amazon Web Services tied more than $100 billion to AWS technologies over a decade in exchange for as much as five gigawatts of extra capacity. A subsequent $35 billion deal with Lambda would provide Nvidia-powered computing capacity at a Hut 8 campus in Texas.
Owning generation equipment could shorten Anthropic’s wait for power at new sites. It may also leave the company more directly exposed to fuel costs, which its own filing lists among the variable expenses it cannot fully predict.
Anthropic could make its stock market debut as soon as this month in what may be one of the biggest flotations on record, as it seeks to fund more than $895 billion in computing infrastructure commitments through 2045. However, financing challenges remain. Blackstone has reportedly warned investors that Anthropic could receive a junk credit rating rather than the investment-grade rating previously expected.
