TL;DR
Piper Sandler’s transaction record confirms OnePWR Solutions sold a 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 Anthropic and OnePWR have not publicly confirmed those details.
OnePWR Solutions sold a power-generation platform to an unnamed frontier AI lab for $3.4 billion, according to a Piper Sandler transaction record dated September 2026. The Financial Times reported that Anthropic was the buyer and that the deal involves 1.7 gigawatts of gas-fired generators, but Anthropic and OnePWR have not publicly confirmed the buyer or the reported equipment details.
Piper Sandler’s transaction page identifies the seller as OnePWR Solutions, a company associated with CK Holdings Group, and says the bank acted as exclusive financial adviser on the sale of its power-generation platform to “a frontier AI lab.” The record lists the transaction under mergers and acquisitions and is dated September 2026. It does not name the buyer, specify generating capacity or describe the equipment.
The buyer and scale come from a separate account. The Financial Times reported on November 8, citing a person familiar with the matter, that Anthropic acquired an order involving 1.7 gigawatts of heavy-duty gas-fired generators. Coverage by Fortune, TechCrunch and Investing.com relayed that reporting. Those accounts say the agreement was reached in late September and included engineering and construction capabilities needed to install the equipment. The companies have not publicly verified those reported terms.
Details of the supplier arrangement are not consistent across the secondary reports. Fortune and Investing.com describe Anthropic as taking over OnePWR’s commitments with Caterpillar, while TechCrunch says Anthropic went directly to Caterpillar after initially planning to buy the equipment from OnePWR. The public record does not establish whether the relevant contract was with OnePWR, Caterpillar or both. The reports also use varying labels such as generators, turbines and engines; the exact equipment type is not confirmed.

Power Supply for Anthropic’s Data Centers
If the reported buyer and capacity are accurate, the transaction would give Anthropic access to a large block of planned generation at a time when power supply is becoming a constraint on data-center construction. Gas-fired equipment can supply electricity on site, potentially reducing dependence on the timing of a grid connection. The Financial Times reporting, as relayed by Fortune, says the equipment is expected to become available over the next two years; the location and commissioning schedule have not been disclosed.
The scale is substantial, but it should not be mistaken for confirmed annual production. At a theoretical continuous output of 1.7 gigawatts, the equipment could generate roughly 14.9 billion kilowatt-hours in a year. That is an arithmetic upper bound, not a forecast: actual generation depends on installation, operating schedules, maintenance, capacity and permits. The stated $3.4 billion sale price also does not, by itself, establish what portion is for equipment, construction or other assets.
The reported move matters beyond Anthropic because it illustrates one possible response to long waits for grid connections and new generating equipment: securing power assets directly. But on-site gas generation also raises questions about emissions, local air quality, water and land use, and whether projects will have carbon controls. The deal’s public record does not answer those questions, and it does not establish that any particular plant has been built or approved.

Why On-Site Gas Is in the Plans
Anthropic has separately signaled that on-site gas power is under consideration. A company job listing first published on November 2 says, “Some of our campuses will run on gas-fired, behind-the-meter generation.” Behind-the-meter generation means electricity produced at a site rather than drawn directly from the public grid. The listing refers to Anthropic’s plans generally; it does not confirm that this reported purchase will supply those campuses.
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 the facilities have since been built or that this transaction is tied to them. Separately, a March 2026 announcement by Caterpillar, OnePWR and carbon-storage company Vero3 described a collaboration on gas-fired data-center power and a proposed 500-megawatt initial development. No public information links that project to the reported Anthropic transaction.
Criticism of gas-powered AI infrastructure has focused on its climate impact. Bloomberg reported a Sierra Club analysis estimating that planned U.S. AI buildout could add 618 million tons of carbon dioxide from the power sector by 2030. That is an estimate about the broader planned buildout, not a measured impact from this deal. The equipment’s operating pattern, emissions controls and relationship to any carbon-capture project have not been disclosed.

— Piper Sandler transaction record
Buyer, Equipment and Sites Unconfirmed
The clearest confirmed facts are the $3.4 billion sale, the seller and the unnamed buyer description in Piper Sandler’s record. Anthropic’s identity as buyer and the 1.7-gigawatt capacity are attributed to Financial Times reporting based on a person familiar with the matter; they are not specified in the bank’s record. Anthropic and OnePWR have not commented publicly, and neither responded to Fortune or Business Insider, according to the source material.
It is not clear where the generators would be installed, when they would arrive or begin operating, who would own and operate the facilities, or how often they would run. The exact equipment type and contract structure also remain unsettled in public accounts. No project-specific permits, emissions controls or carbon-capture arrangements have been established by the information available. The expected availability within two years is reported by Fortune via the Financial Times, not confirmed by a company statement.
Details Needed to Verify the Deal
The next useful confirmation would be statements or filings from Anthropic, OnePWR or Caterpillar that identify the buyer, clarify the equipment orders and describe the transaction’s scope. Project announcements, permitting records and utility or site filings could show where the capacity would be installed and whether it is connected to a specific data-center plan.
Until those details emerge, the transaction should be described as a confirmed sale by OnePWR to an unnamed AI lab, with Anthropic’s role and the 1.7-gigawatt figure reported by the Financial Times. Any assessment of the deal’s power output or environmental effects will depend on information about location, operating hours, fuel use and emissions controls.
Key Questions
What part of the reported deal is confirmed?
Piper Sandler’s record confirms a $3.4 billion sale by OnePWR Solutions of its power-generation platform to an unnamed frontier AI lab. The record is dated September 2026 and does not identify the buyer or give the capacity.
Has Anthropic confirmed it is the buyer?
No. The Financial Times reported Anthropic as the buyer, citing a person familiar with the matter. Anthropic has not publicly confirmed the deal in the source material available as of November 15, 2026.
What equipment is reportedly involved?
The Financial Times reporting, relayed by other outlets, describes 1.7 gigawatts of heavy-duty gas-fired generators. Public accounts vary in how they describe the equipment and contract arrangement, and the specific generator or turbine type is not confirmed.
Where will the generators operate?
The location has not been disclosed. Anthropic’s job listing says some campuses will use gas-fired, behind-the-meter generation, but it does not say those campuses will use equipment from this reported transaction.
What is still unknown about environmental effects?
The public information does not establish the sites, operating hours, emissions controls, permits or any carbon-capture arrangements for this equipment. Broader emissions estimates for AI development are not measurements of this specific deal’s impact.
