Anthropic buys $3.4B of gas generators to power its data centers

Funding

Anthropic paid about $3.4 billion for 1.7 gigawatts of gas generators, the Financial Times reported on November 8, 2026. The seller is OnePWR Solutions, an equipment supplier from San Antonio, Texas. The deal was signed in late September, weeks before Anthropic filed for its IPO. Neither company commented, and Reuters said it could not immediately verify the report.

If confirmed, it is the largest known single purchase of power equipment by an AI company, according to the FT. The way the deal was put together shows how hard it has become to get power hardware at all.

What the FT reported about the OnePWR deal

Anthropic did not buy OnePWR. It took over the company's existing orders for Caterpillar generators, along with the engineering and construction work needed to install them. No OnePWR staff moved to Anthropic.

OnePWR placed those orders about two years ago. It needed money to complete the purchase, the FT reported. Anthropic first planned to buy electricity from OnePWR. It then chose to take over the equipment instead.

Here is what is known so far:

Detail	What was reported
Price	About $3.4 billion
Capacity	1.7 GW of heavy-duty gas generators
Equipment	Caterpillar generators, ordered by OnePWR about two years ago
Signed	Late September 2026
Includes	Engineering and construction work to install the equipment
Site	Not disclosed
Comment	None from Anthropic or OnePWR

That works out to roughly $2,000 per kilowatt, by our math. The FT did not say where the generators will run or how they will get their gas.

So why pay for another company's order book instead of placing an order of its own?

Why Anthropic bought someone else's generator orders

The answer is the queue. Demand for gas turbines and large generators has outgrown factory capacity, as AI developers race to build data centers. New orders now face long manufacturing waits. OnePWR's orders were placed two years ago, so they already sit near the front of that line.

Grid connections are slow too. That pushes data center builders toward their own power plants on site, and gas plants are the fastest to build. Google has taken the same route with its $17 billion Wyoming campus. It will run on gas and a fuel cell plant with carbon capture.

For Anthropic, the generators are one more piece of a much larger buildout.

How gas fits Anthropic's data center plans

Anthropic has been open about its reliance on gas. Its policy page on data centers says much of the new power it needs is natural gas, which "can be brought online quickly". The same page commits Anthropic to selective catalytic reduction on its plants, a standard emissions control. It also says the company will pay for grid upgrades and for price increases its sites cause for local ratepayers.

The IPO filing spells out the risks. According to reporting on the S-1, some of Anthropic's planned data centers depend on dedicated on-site gas generation. Anthropic pays fuel costs on a pass-through basis without caps. If it cannot secure firm gas supply and pipeline capacity, a site could be delayed or abandoned, the filing warns.

Gas power is already part of how Anthropic gets compute. In May, it agreed to use all the capacity at Colossus 1 in Memphis. That xAI data center was first powered by more than 30 gas turbines. In October, it signed a multiyear cloud deal with bitcoin miner IREN.

The generator order is small next to Anthropic's total bill. Its amended S-1 lists about $895.4 billion in compute and lease commitments. Investors are already questioning the IPO valuation, and they will want to know where this purchase sits in those numbers. The reports do not say.

What the generator deal says about Anthropic's power problem

Anthropic is no longer only renting compute. It now holds a power equipment order of its own, worth more than OnePWR could fund. That makes sense if chips are easier to get than electricity, which is how the AI industry has looked all year. The open questions are practical: where the 1.7 GW will run, when the generators arrive and who supplies the gas. Until Anthropic answers them, the deal shows a company securing scarce hardware early, before it knows exactly where it will need it.
