Anthropic has reached an agreement valued at approximately $3.4 billion to secure natural gas-fired generation capacity for its data centers, according to a report by the Financial Times.
According to a report by the Financial Times, the agreement was struck in late September. It secures 1.7 gigawatts of heavy-duty power generation originally ordered through San Antonio-based supplier OnePWR Solutions. If confirmed, the transaction represents the largest known direct procurement of energy-generation assets by a frontier artificial intelligence (AI) laboratory.
Anthropic is not acquiring OnePWR, nor will any OnePWR staff transfer to the AI firm, according to people familiar with the matter. Instead, Anthropic absorbed preexisting equipment commitments that OnePWR placed with manufacturer Caterpillar roughly two years ago.
OnePWR reportedly required additional capital to finalize the transaction, prompting Anthropic, which initially approached the firm as a prospective utility customer, to take over the contracts directly. The arrangement also includes the engineering and construction services required to install the units.
The move underscores an aggressive pivot by AI developers seeking to bypass severe global bottlenecks in power infrastructure. Surging energy demand driven by the race to scale frontier systems such as Anthropic’s Claude family of models has collided with strained electrical grids and multi-year production backlogs for heavy equipment.
By assuming existing purchase commitments rather than initiating a new order, Anthropic avoids years of waiting for factory slots at Caterpillar, where demand for gas turbines and reciprocating engines has outstripped production capacity. The 1.7-gigawatt portfolio offers sufficient baseload capacity to power well over one million homes, providing Anthropic with a dedicated supply line insulated from regional transmission delays.
Neither Anthropic nor OnePWR immediately responded to requests for comment, and the initial reporting could not be independently verified.
The transaction highlights the intensifying capital requirements of the artificial intelligence sector. Recent reports indicate Anthropic projects spending upwards of $500 billion over the next decade on computing and energy infrastructure.
As electricity availability replaces silicon chips as the primary operational ceiling for advanced computing, major developers are increasingly operating as industrial power entities to secure the megawatts needed for future model generations.
