Anthropic reportedly commits $3.4 billion to gas generators as IPO valuation talks shift

The reported agreement covers about $3.4 billion in commitments for 1.7 gigawatts of heavy-duty gas-fired generators.[1] Anthropic obtained the commitments from OnePWR Solutions, a San Antonio-based equipment supplier, after the supplier had ordered the generators approximately two years earlier.[1][2] The commitments were bought in late September, according to the report.[1] The deal also includes engineering and construction capabilities needed to install the equipment.[1] Anthropic did not acquire OnePWR, and OnePWR employees did not transfer to Anthropic.[1] That distinction matters when assessing the deal’s scope.

CNBC reported that demand for Anthropic’s Claude models had prompted the company to seek additional computing and power capacity.[1] Anthropic has identified electricity availability as a significant obstacle to developing and expanding data centers, while its filing said new generation, transmission infrastructure and grid connections can take several years to build.[2] Some planned facilities are expected to use dedicated natural gas generation rather than depend entirely on utility-connected electricity.[2] Brave New Coin reported that the generators are expected to become available soon and over the following two years.[2] For infrastructure planners, the timing and installation capabilities are central details.

Bloomberg reported that potential buyers were discussing a $1.2 trillion to $1.3 trillion valuation range, while some prospective investors were considering as low as $1.1 trillion.[4] Brave New Coin described those expectations as down from earlier discussions near $2 trillion.[2] Bloomberg also reported that Anthropic’s IPO plans ran into a punishing post-election selloff.[4] Anthropic filed an S-1 for a proposed public offering of Class A common stock on Oct. 26 and said it intends to list on the Nasdaq Global Select Market under ticker ANT.[2] The initial filing did not state the share count or proposed price range.[2] The valuation figures are discussions, not an announced offering price.

Anthropic warned that on-site natural gas generation exposes it to fuel-price volatility and supply disruptions outside its control.[2] The approach could provide a dedicated source of power for some planned facilities, but it does not remove exposure to fuel availability or cost.[2] The Financial Times characterized the transaction as the largest known single purchase of power-generation equipment by an AI laboratory.[2] Reuters said it could not immediately verify the report, and Anthropic and OnePWR did not respond to requests for comment.[1]
