TL;DR
Piper Sandler’s transaction record confirms that OnePWR Solutions sold its power generation platform to an unnamed frontier AI lab for $3.4 billion in September 2026. The Financial Times reported that Anthropic was the buyer and that the deal involves 1.7 gigawatts of gas-fired generators, but the companies have not publicly confirmed the buyer or disclosed key operating and emissions details.
OnePWR Solutions sold its power generation platform for $3.4 billion to an unnamed “frontier AI lab,” according to a September transaction record from investment bank Piper Sandler. The Financial Times reported on November 8, citing a person familiar with the matter, that Anthropic was the buyer and that the deal covers 1.7 gigawatts of gas-fired generators; Anthropic and OnePWR have not publicly confirmed that account.
Piper Sandler’s transaction page lists the sale under mergers and acquisitions and says it acted as OnePWR’s exclusive financial adviser. The record identifies the seller as OnePWR Solutions (CK Holdings Group, LLC), dates the transaction “09/26,” and describes the buyer only as a “frontier AI lab.” It does not name the buyer or state the equipment’s capacity.
Details about Anthropic and the equipment come from the Financial Times report, as relayed by Fortune, TechCrunch and Investing.com. Those accounts say the transaction was agreed in late September and involved 1.7 gigawatts of heavy-duty gas-fired generators ordered from Caterpillar by OnePWR about two years earlier. They report that Anthropic took over or otherwise acquired access to the existing equipment orders, along with engineering and construction capabilities. The precise contracting arrangement is not public, and the outlets describe it differently.
The reports also say Anthropic did not buy OnePWR itself and that OnePWR employees did not transfer. Fortune, citing the FT, reported that the generators are expected to become available over the next two years. Anthropic has not commented publicly on the deal, and the source material says the companies did not respond to requests from Fortune or Business Insider.

Why Anthropic Is Seeking On-Site Power
The reported purchase would give Anthropic access to a substantial amount of power equipment at a time when electricity supply and infrastructure can constrain the pace of data-center construction. On-site generation can supply power behind the meter, rather than relying solely on a new connection to the public grid. That may offer a route around long waits for grid connections or newly manufactured turbines, though the deal’s actual effect on Anthropic’s power supply and construction schedule has not been disclosed.
The scale is material if the reported capacity is accurate. At 1.7 gigawatts, the equipment’s theoretical annual output would be about 14.9 billion kilowatt-hours if it ran at full capacity every hour of the year. That is an upper-bound calculation, not a forecast: actual output depends on operating schedules, maintenance, fuel supply and other factors. The purchase price and capacity imply roughly $2 million per megawatt, but that arithmetic does not establish the equipment-only cost because the reported deal may include installation-related services.
Gas-fired generation also carries climate and local-environment implications. A Sierra Club analysis, as reported by Bloomberg, estimates that planned US AI development could add 618 million tons of CO2 from the power sector by 2030. That is a broader estimate of AI-related buildout, not an emissions estimate for this OnePWR deal. The deal’s own emissions, operating hours and controls have not been made public.

The Evidence Behind the Buyer Report
The evidence is uneven. Piper Sandler confirms the sale and price, but its record leaves the buyer unnamed. The identification of Anthropic and the 1.7-gigawatt figure come from the Financial Times, which cited a person familiar with the matter. The source material notes that the FT’s original report was not accessible to its author; the details were relayed through other outlets. Anthropic and OnePWR have not publicly verified them.
There is separate evidence that gas power is part of Anthropic’s planning. A company job listing first published November 2 says, “Some of our campuses will run on gas-fired, behind-the-meter generation.” The listing describes power produced at a site rather than drawn from the public grid. It also refers to work involving reciprocating engine generator sets, gas turbines and fuel cells, but does not identify which technology is covered by the reported OnePWR order.
In 2025, Anthropic projected that developing a single advanced model could require a 2-gigawatt data center in 2027 and a 5-gigawatt facility in 2028. Those were company projections, not evidence that particular facilities have been built or that the reported generators will serve them. Separately, Caterpillar, OnePWR and carbon-storage company Vero3 announced a collaboration in March 2026 on gas-fired power with carbon capture for data centers. That announcement described a proposed 500-megawatt site; no public information in the source material connects it to Anthropic’s reported purchase.
“Piper Sandler served as exclusive financial advisor for OnePwr on its sale of its power generation platform to a frontier AI lab.”
— Piper Sandler transaction record
Buyer, Contracts and Emissions Still Unclear
Anthropic’s role remains reported, not publicly confirmed. Piper Sandler’s record names no buyer, and Anthropic and OnePWR have not commented. The reported accounts also differ on how the equipment orders were transferred: Fortune and Investing.com describe Anthropic taking over OnePWR’s commitments with Caterpillar, while TechCrunch says Anthropic went directly to Caterpillar instead of buying the equipment from OnePWR. The contract parties and transaction structure are not public.
The equipment description is also unresolved. Coverage uses terms including generators, turbines and engines, while the FT wording relayed by outlets is “gas-fired generators.” Anthropic’s job listing mentions several types of on-site power technology but does not say which one is in this order. The source material does not establish where the units will be installed, who will own or operate them, when they will be commissioned, how often they will run, or what permits and emissions controls will apply.
Nor is it clear whether the reported equipment is connected to OnePWR’s separate 500-megawatt project announced with Caterpillar and Vero3. No public evidence in the available material links that project to Anthropic’s reported deal. The expected availability date and the intended data-center sites also remain based on reporting rather than a public project announcement from the companies.
Company Confirmation and Project Details
The next clarity is likely to come from a statement or filing that identifies the buyer, explains the contract arrangement and specifies what assets and services the $3.4 billion covers. Until then, the sale and price are documented, while Anthropic’s identity as buyer and the reported capacity rest on attributed reporting.
Further disclosures would be needed to establish where the equipment will be deployed, when it will be ready, who will operate it and what environmental permits and controls will govern its use. Any assessment of the deal’s power contribution or emissions will also depend on actual operating schedules and output, details that have not been released as of November 15, 2026.
