Anthropic Takes on a $3.4 Billion Commitment to Buy 1.7 Gigawatts of Gas Generators
According to the Financial Times, AI lab Anthropic in late September bought a $3.4 billion commitment to purchase 1.7 gigawatts of heavy-duty gas generators from San Antonio, Texas-based equipment supplier OnePWR Solutions. Anthropic did not acquire OnePWR itself; the deal also includes the engineering and construction capabilities needed to install the generators, and no OnePWR employees moved to Anthropic.
People familiar with the matter said OnePWR had ordered these generators from Caterpillar two years earlier, but needed financing to complete the deal. Anthropic initially planned to become OnePWR's customer, and later chose to take over the equipment OnePWR had ordered from Caterpillar. The report described this as the largest single power-equipment purchase known in the AI lab sector.
Neither Anthropic nor OnePWR commented on the report, and Reuters said it could not immediately verify the related content. The deployment location has not been disclosed.

The AI lab is directly intervening in power-equipment procurement to bypass intermediaries and supply-chain bottlenecks. Anthropic is not placing a new order; instead, it is taking over a commitment that OnePWR had already placed with Caterpillar about two years earlier and had not completed because of financing problems. This gives the company equipment that could be delivered within nearly two years, whereas a new order could face a longer wait and higher prices.
The deal structure shows Anthropic shifting from being a power customer to being the holder of the equipment commitment. It did not acquire OnePWR or take on its employees; it only obtained the generator order and the supporting construction capability. This reduces integration costs while preserving control over critical power assets, in line with data-center demand for on-site or near-site generation.
Delivery lead times from heavy-equipment suppliers such as Caterpillar are becoming a constraint on AI expansion. The 1.7-gigawatt scale is equivalent to a large power plant and is described as the largest single purchase known in the AI lab sector. Other labs have also secured power by buying mobile gas turbines and similar equipment, reflecting how self-owned or pre-locked generation equipment is becoming a competitive resource when grid access is limited.
The information from knowledgeable sources and the companies' refusal to comment indicate that the details still depend on a single reporting source. The deployment location, the specific delivery timeline, and how this relates to Anthropic's overall infrastructure spending have not been disclosed. While gas-fired generation can quickly add power, it also exposes the company to fuel-price volatility and permitting risks.

By taking over already ordered power equipment rather than placing a new purchase, AI labs shorten delivery cycles and lock in scarce capacity.
Not acquiring the supplier and not taking on its employees, while only obtaining the order and construction capability, lowers integration costs while preserving asset control.
A 1.7-gigawatt gas-generator commitment shows that power equipment has become a competitive AI infrastructure resource alongside chips.
