TL;DR
Piper Sandler lists a $3.4 billion sale of OnePWR Solutions’ power generation platform to an unnamed frontier AI lab. The Financial Times reported that Anthropic is the buyer and that the deal covers 1.7 gigawatts of gas-fired generators, but Anthropic and OnePWR have not confirmed those details publicly.
Investment bank Piper Sandler lists a $3.4 billion sale of OnePWR Solutions’ power generation platform to an unnamed frontier AI lab, while a Financial Times report identifies Anthropic as the buyer. The bank’s transaction record confirms the sale and its price, but Anthropic and OnePWR have not publicly confirmed the buyer’s identity, the reported 1.7-gigawatt capacity, or other deal terms.
Piper Sandler’s transaction page for OnePWR Solutions, dated September 2026, says the bank served as exclusive financial adviser on the company’s sale of its power generation platform to “a frontier AI lab.” The listing gives the transaction value as $3.4 billion but does not name the buyer or state the equipment’s capacity. It categorizes the transaction as a sell-side merger and acquisition in the bank’s energy, power and infrastructure group.
The Financial Times reported on November 8, citing a person familiar with the matter, that Anthropic bought the equipment and that the deal covers 1.7 gigawatts of heavy-duty gas-fired generators. The report, as relayed by Fortune, TechCrunch and Investing.com, said the agreement was reached in late September. Those outlets also reported that the equipment had been ordered from Caterpillar by OnePWR about two years earlier, and that the deal includes engineering and construction capabilities needed for installation.
Public reporting does not fully agree on the commercial arrangement. Fortune and Investing.com describe Anthropic as taking over OnePWR’s commitments with Caterpillar; TechCrunch says Anthropic went directly to Caterpillar after initially planning to buy the generators from OnePWR. The Financial Times report says Anthropic did not acquire OnePWR and that its employees did not transfer. Neither Anthropic nor OnePWR has publicly commented, and both reportedly did not respond to inquiries from Fortune or Business Insider.

AI Power Needs Move On Site
If the Financial Times account is accurate, the deal would give Anthropic access to a large amount of power-generation equipment at a time when new turbines and grid connections can take years to obtain. The company’s own 2025 projections described a need for a 2-gigawatt data center in 2027 and a 5-gigawatt data center in 2028 to develop a single advanced model. The reported generator capacity is not proof that the equipment will serve those facilities, but it signals the scale of power planning at issue.
Anthropic has also acknowledged that some campuses may use gas-fired, behind-the-meter generation—power produced on site rather than drawn from the public grid. Such arrangements could give a data center a more direct supply while grid connections are delayed. They also bring questions about fuel use, emissions, local air quality, permitting and who will operate the equipment. Climate groups have criticized the broader AI power buildout; a Sierra Club analysis, as reported by Bloomberg, estimates it could add 618 million tons of CO2 from the U.S. power sector by 2030. That figure concerns planned AI infrastructure overall, not this transaction alone.

What the Public Record Shows
The evidence comes from sources with different levels of direct confirmation. Piper Sandler’s transaction record is primary documentation of a $3.4 billion sale to an unnamed frontier AI lab. Anthropic’s reported role and the 1.7-gigawatt figure come from the Financial Times, which cited an unnamed person familiar with the matter; the original report was not available to the source article, which relied on other outlets’ accounts of it.
An Anthropic power-engineering job listing, first published November 2, offers separate evidence that gas power is part of the company’s planning. It says, “Some of our campuses will run on gas-fired, behind-the-meter generation.” The listing also names several technologies—reciprocating engine generator sets, gas turbines and fuel cells—but does not establish which, if any, are covered by the reported order.
OnePWR, Caterpillar and carbon-storage company Vero3 announced a collaboration on gas-fired power with carbon capture on March 2, 2026. The announcement described OnePWR as building, owning and operating power generation and related infrastructure, with an initial 500-megawatt project expected to begin development that year. No public information links that project to the reported Anthropic transaction.
“Piper Sandler served as exclusive financial advisor for OnePwr on its sale of its power generation platform to a frontier AI lab.”

Buyer, Equipment and Site Details
The central unresolved point is whether Anthropic is definitively the buyer: that identification comes from the Financial Times’ account, not the bank’s transaction page or a public company statement. The deal’s reported capacity and the precise terms also remain unconfirmed. Accounts differ on whether Anthropic took over OnePWR’s Caterpillar orders or contracted directly with Caterpillar.
It is also unclear what specific equipment the order includes, where it will be installed, when it will arrive, who will operate it and how often it will run. Public reporting does not specify the permits, emissions controls or fuel arrangements that would apply. The $3.4 billion figure is the recorded platform-sale value; the public record does not provide a breakdown of how much covers generators, engineering, construction or other assets.
Awaiting Company and Project Details
The next useful confirmation would be a statement or filing from Anthropic, OnePWR or Caterpillar addressing the buyer, transaction structure, equipment and delivery schedule. Project-level disclosures or permitting records could clarify where the generators are planned and what environmental controls apply. Until then, the sale price is documented, while Anthropic’s reported role and the deal’s operational details remain based on media reporting. The equipment’s expected availability within the next two years was reported by Fortune citing the Financial Times; a confirmed delivery timetable has not been made public.
