Anthropic reportedly buys $3.4 billion of gas generators to power its AI data centers

Anthropic, the developer of the Claude AI models, has struck a deal worth about $3.4 billion to secure gas-fired power generators for data centers, the Financial Times reported on Sunday, 8 November 2026, as relayed by Reuters and CNBC.

The reported deal

According to the report, Anthropic bought commitments for 1.7 gigawatts of heavy-duty generators in late September from OnePWR Solutions, an equipment supplier based in San Antonio, Texas. Anthropic did not acquire OnePWR, and none of its employees moved to the AI company, but the deal included the engineering and construction capabilities needed to install the generators, the FT said citing a person familiar with the matter. The Next Web, summarizing the FT, reported that Anthropic took over OnePWR’s existing generator orders with Caterpillar.

Why it matters

Power has become one of the tightest bottlenecks for AI. On-site gas generation lets data-center builders avoid waiting years for grid connections, but it adds fuel costs and greenhouse-gas emissions. Reuters reported in September that Anthropic expects to spend more than $500 billion over the next 10 years on AI infrastructure, driven by demand for Claude.

Caveats

This is a media report based on an unnamed source. Reuters could not immediately verify it, and Anthropic and OnePWR did not respond to requests for comment. Where the generators will be installed and when they will run was not reported.
