TL;DR
Piper Sandler records a September 2026 sale of OnePWR Solutions’ power generation platform to an unnamed frontier AI lab for $3.4 billion. The Financial Times, citing a person familiar with the matter, identifies Anthropic as the buyer and reports the deal covers 1.7 gigawatts of gas-fired generators; Anthropic and OnePWR have not publicly confirmed those details.
Piper Sandler’s transaction record lists a $3.4 billion sale of OnePWR Solutions’ power generation platform to an unnamed “frontier AI lab,” dated September 2026. The Financial Times reported on November 8, citing a person familiar with the matter, that Anthropic is the buyer and that the deal covers 1.7 gigawatts of gas-fired generators, but neither company has publicly confirmed that identification or the reported capacity.
The bank’s transaction page identifies Piper Sandler as OnePWR’s exclusive financial adviser on the sale. It names the seller as OnePWR Solutions, associated with CK Holdings Group, LLC, but does not identify the buyer or state the equipment’s capacity. The listed amount is $3.4 billion, and the transaction is dated “09/26.”
The Financial Times’ account, relayed by Fortune, TechCrunch and Investing.com, says the buyer is Anthropic and the equipment consists of 1.7 gigawatts of heavy-duty gas-fired generators. The FT reportedly cited one person familiar with the matter. The reports say the agreement was reached in late September and involved equipment OnePWR had ordered from Caterpillar. Anthropic and OnePWR have not commented publicly, according to the source material.
The accounts do not describe the commercial arrangement identically. Fortune and Investing.com report that Anthropic took over OnePWR’s commitments with Caterpillar; TechCrunch says Anthropic went directly to Caterpillar rather than buying the equipment from OnePWR. Reports also say the transaction included engineering and construction capabilities, but the exact scope and contractual counterparties are not public. The reports say Anthropic did not acquire OnePWR itself and that OnePWR employees did not transfer.

A Faster Route to Data-Center Power
If the reported buyer and capacity are accurate, the deal would give Anthropic access to a large power supply without waiting solely for new grid connections or newly ordered equipment. Power availability has become a constraint on data-center construction: the source material cites reporting that turbine orders and grid connection queues can extend for years. Acquiring existing equipment orders could shorten one part of that wait, though it does not establish that the generators are installed, permitted or producing electricity.
The scale has implications beyond Anthropic’s infrastructure plans. Gas-fired generation can provide electricity on site, but it also raises questions about emissions, local air quality, fuel supply and the role of fossil fuels in AI expansion. A Sierra Club analysis, as reported by Bloomberg, estimates that planned U.S. AI development could add 618 million tons of CO2 from the power sector by 2030. That is an estimate about the broader planned buildout, not a measured emissions figure for this deal, and the source material does not establish how much of that estimate is attributable to Anthropic.
For customers and communities, the practical effects depend on where the equipment is installed and how it is operated. The transaction record alone does not show whether the power will serve particular data centers, supplement grid supply or run continuously. Those details will shape both the project’s reliability benefits and its environmental footprint.

Anthropic’s Stated On-Site Power Plans
Anthropic has described on-site gas generation as part of its infrastructure planning. A company job listing first published November 2 says, “Some of our campuses will run on gas-fired, behind-the-meter generation.” Behind-the-meter generation produces power at a site rather than drawing all of it from the public grid. The listing supports the conclusion that Anthropic is considering gas-fired power at some campuses; it does not confirm that the reported OnePWR equipment is intended for any specific campus.
In 2025, Anthropic projected that developing a single advanced model could require a 2 GW data center in 2027 and a 5 GW data center in 2028. Those were projections about future computing needs, not confirmation that either facility has been built or that this reported generator purchase is allocated to them.
OnePWR, Caterpillar and carbon-storage company Vero3 announced a separate collaboration on gas-fired power with carbon capture on March 2, 2026. The announcement said OnePWR would build, own and operate generation and related infrastructure, with an initial 500 MW site expected to begin development that year. The available material does not connect that project to Anthropic’s reported equipment deal. Reports also use “generators,” “turbines” and “engines” in describing the equipment; Anthropic’s job listing names several types of on-site power systems, but the technology in this order has not been confirmed.
“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, Equipment and Site Details
The public transaction record does not name Anthropic, and the company has not publicly confirmed that it bought the platform. The FT’s identification rests on a person familiar with the matter, as relayed by other outlets. The reported 1.7 GW capacity, late-September agreement date and equipment terms are likewise not stated on Piper Sandler’s page.
It remains unclear whether Anthropic assumed OnePWR’s existing Caterpillar orders or contracted directly with Caterpillar, as accounts differ. The exact equipment type, purchase terms and scope of the engineering and construction work are also undisclosed. Fortune’s report, citing the FT, says the generators are expected to become available within two years; the companies have not publicly provided a delivery schedule in the material available here.
No location, permitting plan, operator, operating schedule, fuel arrangement or emissions controls have been made public. The source material also does not confirm whether carbon capture will be used on these generators. Until the companies or relevant authorities provide those details, the deal’s eventual electricity output and local environmental effects cannot be assessed from the reported capacity alone.
Watch for Project and Permit Filings
The next useful confirmations would come from Anthropic, OnePWR or Caterpillar: whether Anthropic is the buyer, which equipment and contracts are included, and when deliveries are expected. Project plans or regulatory filings could clarify proposed locations, construction schedules, emissions controls and operating permits.
As of November 15, 2026, the bank record establishes a $3.4 billion sale to an unnamed AI lab, while the identification of Anthropic and the 1.7 GW figure remain reported rather than publicly confirmed by the companies. Any assessment of how much power the deal will provide, or what it will mean for emissions and nearby communities, will depend on those unresolved details.
