TL;DR
Piper Sandler lists a September 2026 sale of OnePWR Solutions’ power-generation platform to an unnamed frontier AI lab for $3.4 billion. The Financial Times reported, citing a person familiar with the matter, that Anthropic is the buyer and that the deal involves 1.7 gigawatts of gas-fired generators; Anthropic and OnePWR have not publicly confirmed that account.
Piper Sandler lists a $3.4 billion sale of OnePWR Solutions’ power-generation platform to an unnamed frontier AI lab, while a November 8 Financial Times report identifies Anthropic as the buyer. The bank’s transaction record confirms the sale and its September 2026 date, but the buyer and the reported 1.7 gigawatts of gas-fired generators have not been confirmed publicly by Anthropic or OnePWR.
The transaction appears on Piper Sandler’s website under mergers and acquisitions. The bank says it served as exclusive financial adviser to OnePWR on the sale of its power-generation platform to a “frontier AI lab.” Its listing, dated September 2026, gives the value as $3.4 billion but does not identify the buyer or describe the equipment’s capacity.
The buyer and scale come from reporting by the Financial Times, which cited a person familiar with the matter. As relayed by Fortune, TechCrunch and Investing.com, the deal involves 1.7 gigawatts of heavy-duty gas-fired generators ordered by OnePWR from Caterpillar about two years earlier. The reports say Anthropic had considered becoming a OnePWR customer before taking over or otherwise assuming the existing equipment orders. They also say the transaction includes engineering and construction capabilities needed to install the equipment.
Some details differ among those accounts. Fortune and Investing.com describe Anthropic taking over OnePWR’s commitments with Caterpillar; TechCrunch says Anthropic went directly to Caterpillar rather than buying the equipment from OnePWR. The reports also say Anthropic did not acquire OnePWR and that OnePWR employees did not transfer. The exact contract structure and the equipment type have not been made public. Reports use “generators,” “turbines” and “engines,” while Anthropic’s job listing names several types of on-site power equipment.

Gas Power for AI Data Centers
If the reported buyer and capacity are accurate, the deal would give Anthropic access to a large block of power-generation equipment while electricity supply and new infrastructure are difficult to secure quickly. That matters because advanced AI data centers require substantial, steady electricity, and delays in grid connections or equipment deliveries can affect when computing capacity can be brought online. A deal for equipment already ordered could offer an alternative to waiting for a new order, although the reports do not establish when the generators will be installed or operating.
The energy choice also carries climate and local-impact questions. Gas-fired generation emits carbon dioxide when operated, and the eventual emissions depend on how often and at what output the equipment runs, as well as on its design and any controls. A Sierra Club analysis, reported by Bloomberg, estimates that planned US AI power development could add 618 million tons of CO2 from the power sector by 2030. That is a sector-wide projection, not an estimate for this deal, and it does not establish the emissions of any specific Anthropic project.
For communities, utilities and companies buying AI services, the practical effects depend on where the facilities are built, how they are powered, and whether the generators operate as primary or backup supply. Those details are not yet public, so the transaction’s real-world effects cannot be calculated from the reported capacity alone.

Anthropic’s On-Site Power Plans
The reported purchase fits with Anthropic’s stated interest in supplying some facilities with power generated on site. A job listing first published November 2 says: “Some of our campuses will run on gas-fired, behind-the-meter generation.” Behind-the-meter power is produced at a facility rather than drawn directly from the public grid. The listing establishes that Anthropic is considering this approach for some campuses; it does not confirm that the OnePWR equipment will serve any particular site.
Anthropic has described the scale of its expected computing needs. In 2025, it projected that developing one advanced model could require a 2-gigawatt data center in 2027 and a 5-gigawatt data center in 2028. Those figures are company projections, not confirmation that facilities of those sizes have been built or that this generator order is dedicated to them.
OnePWR has also announced other work in gas-fired power. On March 2, 2026, Caterpillar, OnePWR and carbon-storage company Vero3 announced a collaboration on gas power with carbon capture for data centers. The announcement said OnePWR would build, own and operate power generation and associated infrastructure, with an initial 500-megawatt site expected to begin development that year. No public information connects that project to the reported Anthropic deal, and it does not establish that carbon capture is part of the generator order.

Buyer, Contracts and Sites Unconfirmed
Anthropic and OnePWR have not publicly confirmed the reported buyer identity, the 1.7-gigawatt figure or the transaction details. The Financial Times account relies on a person familiar with the matter, and the original report was not independently available in the source material. Piper Sandler’s public record confirms the sale to an unnamed lab, not the additional details.
The contract path is also unsettled: the reports differ on whether Anthropic took over OnePWR’s Caterpillar commitments or contracted directly with Caterpillar. The equipment description is not precise enough to establish whether the order covers gas turbines, reciprocating engines or another configuration. There is no public confirmation of where the equipment will be installed, which projects it will serve, who will operate it, how often it will run, or what permits and emissions controls will apply.
Fortune reported that the generators are expected to become available within the next two years. That is a reported expected availability date, not confirmation of delivery, commissioning or commercial operation. The $3.4 billion price is documented by Piper Sandler, but the public listing does not itemize what the amount covers.
Watch for Project and Permit Details
The next concrete information would be public confirmation from Anthropic, OnePWR or Caterpillar about the buyer, contract structure, equipment and delivery schedule. Updates to the companies’ project announcements or regulatory filings could clarify whether the order is tied to specific data-center sites and whether the equipment will provide primary power, backup power or both.
Once locations and operating plans are disclosed, permitting records and project documents may show who will run the generators and what emissions controls are proposed. Until then, the transaction record establishes a $3.4 billion platform sale, while Anthropic’s role and the reported generator capacity remain attributed to press reporting rather than confirmed by the companies.
Key Questions
Is Anthropic confirmed as the buyer?
No. Piper Sandler confirms a sale to an unnamed frontier AI lab. The Financial Times reported that Anthropic is the buyer, citing a person familiar with the matter; Anthropic and OnePWR have not publicly confirmed it.
What does the reported deal include?
Press reports describe 1.7 gigawatts of gas-fired generators, along with engineering and construction capabilities. The bank’s public transaction record does not list the capacity or equipment details, and the companies have not confirmed the account.
Why would an AI company buy power equipment?
AI data centers require large, continuous electricity supplies. On-site generation can provide power without relying entirely on a new grid connection, but the reported deal’s intended sites and operating role have not been disclosed.
Does the deal include carbon capture?
That has not been established. OnePWR separately announced a collaboration with Caterpillar and Vero3 on gas-fired power with carbon capture. No public information connects that project to the equipment reportedly associated with Anthropic.
