Anthropic has a power problem, and it just spent $3.4 billion trying to fix it. The Financial Times reported on Sunday that the company behind Claude struck a deal in late September to secure 1.7 gigawatts of gas-fired generators for its AI data centers, taking over generator orders placed by a Texas equipment supplier. If the report holds up, it’s one of the clearest signs yet that the AI race has a new bottleneck, and it isn’t chips.

The deal, as the Financial Times described it, covers commitments for heavy-duty Caterpillar generators that San Antonio-based OnePWR Solutions ordered about two years ago and needed financing to complete. Anthropic stepped in and took over those orders. It did not buy OnePWR itself, and none of the supplier’s employees moved to the AI company, but the agreement included the engineering and construction capabilities needed to install the generators.

Neither company has confirmed any of this. Anthropic and OnePWR did not respond to requests for comment, and Reuters, which reported the Financial Times story, said it could not immediately verify it. That’s worth keeping in mind: the $3.4 billion figure comes from a single source familiar with the matter, not from a filing or a company statement.

The electricity bill is now the AI bill.

What Anthropic bought with its $3.4 billion

A 1.7-gigawatt generator fleet is not a rounding error. It’s the kind of capacity a mid-size city uses, and it would give Anthropic power it controls outright, on its own schedule, instead of power it has to wait for from a utility. For a company training models that run for months at a time, that difference matters. A training run that stops because the grid can’t deliver is a training run that costs millions and delivers nothing.

Anthropic’s own paperwork shows how big the appetite has become. Its amended S-1 filing from November 2 reports roughly $17 billion in third-quarter revenue against about $895.4 billion in purchase and lease commitments, most of it tied to computing and infrastructure. That’s the scale of the bet: revenue in the tens of billions, commitments approaching a trillion. Electricity sits underneath all of it.

The timing adds another layer. Anthropic is expected to start its IPO roadshow this week, with a listing planned before Thanksgiving. Investors will get to ask, in person, how the company plans to power the buildout it has promised. A $3.4 billion generator deal is one answer, even if it’s an answer the company hasn’t given itself yet.

Why Anthropic gas generators make sense right now

The simple version is that the power grid can’t keep up. Data centers are being built faster than utilities can connect them, and the equipment to generate power is booked out for years. Companies that once worried about getting enough Nvidia chips now worry about getting enough megawatts, and the ones with money are buying their way to the front of the line.

Reuters reported on Monday that the scramble has gone global. Utilities, developers, and AI infrastructure firms are scouring the world for second-hand gas turbines, reviving mothballed machines, and converting retired jet engines into power units. Worldwide turbine orders now top 100 gigawatts, according to Wood Mackenzie, while global production capacity sits somewhere between 60 and 70 gigawatts. Demand is running well ahead of supply, and the gap is widening.

Delivery times tell the story. A new gas turbine in the United States now takes about six years to arrive on average, Wood Mackenzie senior analyst Aurora Tenorio told Reuters. “Delivery conversations are firmly focused on the 2030 to 2031 window,” she said. That’s a long time to wait when your competitors are building data centers now.

The prices explain why buyers are getting creative. New turbines cost about $2 million to $2.5 million per megawatt, according to Aurora Energy Research, while well-maintained used units sell for roughly $1.5 million to $1.7 million per megawatt. Refurbished units go for about $1.3 million. Two 14.5-megawatt turbines made by Solar Turbines, a Caterpillar unit, recently sold for $12.5 million, or around $430,000 per megawatt. New ones would have cost about $35 million and taken five years to deliver.

Anthropic isn’t the only buyer improvising. AI infrastructure firm Crusoe ordered 13 aeroderivative gas turbines from ProEnergy in April, with a combined capacity of 650 megawatts, for its US data center projects. Finland’s Wartsila has booked around 3 gigawatts of orders for gas-engine power units from US data centers since last spring. The pattern is the same everywhere: if you can’t wait for the grid, you bring your own power.

Why this matters

The generator deal, if it goes through as reported, says something about where the AI industry’s real constraint has moved. For two years the story was chips: who could buy them, who could afford them, who would get cut off. The chip shortage hasn’t vanished, but the power shortage has caught up with it. You can have all the GPUs in the world and still sit idle without electricity.

It also says something about how Anthropic sees itself. The company is weeks away from a public listing, and its filing reads like a company preparing to spend staggering sums on infrastructure. Buying generators is the physical version of that filing: concrete, expensive, and hard to undo. It suggests Anthropic expects its compute needs to keep growing fast enough that waiting for the grid isn’t an option.

There are open questions the reporting doesn’t answer yet. Nobody has said where the generators will be installed, which data centers they’ll serve, or how long they’ll run. Gas generators also mean emissions, and Anthropic has said little publicly about the climate cost of its buildout. Those details will matter once the company is public and has to answer for them in earnings calls, not just in news reports.

For now, the deal is a useful marker. The AI companies spent 2025 racing to buy chips. In 2026, they’re racing to buy power. Anthropic just paid $3.4 billion to make sure it doesn’t lose that race.

Frequently asked questions

Why did Anthropic buy gas generators?

Anthropic reportedly needs guaranteed electricity for its AI data centers, and grid connections plus new turbine deliveries now take years. Buying 1.7 gigawatts of gas generators locks in power it can control directly instead of waiting in line.

How much did Anthropic pay for the generators?

About $3.4 billion, according to the Financial Times. The deal, struck in late September, covers commitments for 1.7 gigawatts of heavy-duty gas-fired generators that Anthropic took over from Texas supplier OnePWR Solutions.

Did Anthropic buy OnePWR Solutions?

No. Anthropic took over OnePWR’s existing orders for Caterpillar generators but did not acquire the company, and none of OnePWR’s employees transferred to Anthropic. The deal did include engineering and construction capabilities to install the generators.

Is the Anthropic generator deal confirmed?

Not by the companies involved. The Financial Times reported the deal citing a person familiar with the matter, and Reuters said it could not immediately verify the report. Neither Anthropic nor OnePWR responded to requests for comment.
