TL;DR
Piper Sandler’s transaction record lists a $3.4 billion sale by OnePWR Solutions of its power-generation platform to an unnamed frontier AI lab. The Financial Times reported that Anthropic is the buyer and that the deal involves 1.7 gigawatts of gas-fired generators, but Anthropic and OnePWR have not publicly confirmed those details.
Piper Sandler lists a $3.4 billion sale of OnePWR Solutions’ power-generation platform to an unnamed frontier AI lab, in a transaction 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; neither company has publicly confirmed that identification.
Piper Sandler’s transaction record describes the bank as the exclusive financial adviser to OnePWR on the sale. It names the buyer only as “a frontier AI lab” and does not state the equipment’s capacity. The $3.4 billion figure and the broad description of the sale are therefore supported by the bank’s record; the buyer’s identity and the reported 1.7-gigawatt scale come from media reporting.
The Financial Times report, relayed by Fortune, TechCrunch and Investing.com, says the agreement was reached in late September and involves 1.7 gigawatts of heavy-duty gas-fired generators. The reports say OnePWR had ordered equipment from Caterpillar about two years earlier and needed financing to complete the transaction. They also describe engineering and construction capabilities as part of the arrangement. The precise structure is unclear: some accounts say Anthropic took over OnePWR’s commitments to Caterpillar, while TechCrunch says Anthropic went directly to the manufacturer.
The available descriptions do not establish whether the order consists of turbines, reciprocating engines or another generator configuration. Anthropic and OnePWR have not commented publicly on the reported deal, and neither responded to Fortune or Business Insider, according to the source account. The reporting also says Anthropic did not acquire OnePWR itself and that OnePWR employees did not transfer.

Power for Anthropic’s Expansion
If the Financial Times’ account is accurate, the transaction would give Anthropic access to a substantial block of planned generation equipment as power demand grows across the AI sector. Large data centers need dependable electricity, while new grid connections and new generation equipment can take years to secure. Buying into existing equipment orders could help shorten that wait, although the reported deal does not by itself establish when or where the generators will operate.
The scale also matters beyond Anthropic. A 1.7-gigawatt fleet would be a major energy asset, but its actual output would depend on how often it runs, its configuration and operating conditions. A simple full-output calculation would not show actual annual generation. The use of gas-fired equipment also brings questions about emissions, local air quality, permitting and whether any carbon-capture systems are planned. Those implications cannot be determined from the transaction record or reporting alone.
For customers and communities, the purchase could signal that AI companies are seeking power solutions outside ordinary grid supply. It does not show that Anthropic’s services will become cheaper, that the equipment is already installed, or that the company will operate every generator continuously. Those outcomes depend on details that have not been made public.

Why AI Firms Seek On-Site Power
Anthropic has separately indicated that gas-fired generation is part of its energy 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 power is produced at or near a facility rather than drawn directly from the public grid. The listing establishes that the company is planning for this kind of power at some campuses; it does not confirm that the OnePWR transaction is connected to those sites.
In 2025, Anthropic projected that developing one advanced model could require a 2-gigawatt data center in 2027 and a 5-gigawatt data center in 2028. Those were projections, not confirmation that such facilities have been built. The company’s stated needs help explain why securing equipment in advance may appeal to AI developers facing long waits for generation and grid access.
OnePWR, based in San Antonio, has also been involved in a separate gas-power initiative. In March 2026, Caterpillar, OnePWR and carbon-storage company Vero3 announced a collaboration on gas-fired power with carbon capture for data centers. The announcement said OnePWR would build, own and operate generation and related infrastructure, with an initial 500-megawatt site expected to begin development that year. No public information links that project to Anthropic’s reported purchase.

Buyer and Equipment Details
Anthropic’s identity as the buyer remains a media-reported claim, not a detail confirmed in the bank’s public record or by either company. The contract structure is also unsettled in published accounts, which differ on whether Anthropic took over OnePWR’s Caterpillar orders or contracted directly with Caterpillar.
The public information does not specify the equipment type, installation sites, delivery schedule, operating plan, permits or emissions controls. Fortune’s account says the generators are expected to become available within the next two years, but that timing has not been confirmed by Anthropic or OnePWR. It is also unknown whether carbon capture will be used for any equipment in the reported transaction. The separate Vero3 collaboration does not establish that it applies here.
Awaiting Company Confirmation
The next substantive update would be confirmation from Anthropic, OnePWR or Caterpillar addressing the buyer, contract structure, equipment and expected delivery. Details about sites, construction, permits and operations would clarify how the reported order might affect power supply and emissions. Until companies or regulatory filings provide that information, the $3.4 billion sale is the confirmed transaction record, while the Anthropic identification and the reported 1.7-gigawatt scope remain attributed to the Financial Times account.
