Anthropic Reportedly Buys $3.4B of Gas Generators for AI Power

Anthropic, the AI company behind the Claude chatbot, agreed to pay $3.4 billion for 1.7 gigawatts of gas-fired generators to power its data centers, the Financial Times reported on Sunday, November 8, 2026. Neither company has confirmed it: both declined to comment to the FT, according to The Next Web.

What was reported

According to the FT's account, as relayed by The Next Web and The Energy Mag:

• The deal was signed in late September 2026 with OnePWR Solutions, a power supplier based in San Antonio, Texas.
• The heavy-duty generators come from Caterpillar (CAT). OnePWR placed the orders roughly two years ago and lacked the funds to finish paying for them.
• Anthropic's original plan was to be a OnePWR power customer. The deal instead hands Anthropic the equipment orders themselves, plus the engineering and construction work to get the machines installed. The 1.7-gigawatt figure came from one person familiar with the deal, the FT said.
• Anthropic did not buy OnePWR itself, and it has not been reported where the generators will be used.

The Energy Mag also points to a deal list from investment bank Piper Sandler, OnePWR's adviser, that describes a $3.4 billion sale of OnePWR's power-generation platform to an unnamed AI lab in September. The listing does not name Anthropic.

Why it matters for investors

AI developers are competing to lock in electricity as power runs short, Seeking Alpha noted. The FT described the deal as the largest known single purchase of power equipment by an AI company, according to The Next Web and The Energy Mag.

For public-market investors, two things stand out:

• Equipment makers. Caterpillar builds the generators in this deal. Keep in mind that the reported orders were placed years ago and changed hands, so they are not necessarily new orders for Caterpillar.
• Anthropic's own IPO. Anthropic has filed to go public. The Next Web says its amended IPO filing listed $895 billion of commitments, nearly all of them tied to compute and infrastructure. The Energy Mag says Anthropic disclosed on Nov. 2 that it plans to spend more than $895 billion in the years ahead.
