Anthropic buys $3.4B of commitments for 1.7 GW of gas-fired generators to power data centres, FT reports

The commitments for heavy-duty generators came from San Antonio supplier OnePWR Solutions in late September and include installation capabilities; Anthropic did not buy the company, and neither firm commented.
Why it matters
Power has become the binding constraint on AI build-outs, and some labs are now securing their own generation rather than waiting for grid connections. The Financial Times reports Anthropic bought commitments for 1.7 gigawatts of heavy-duty gas-fired generators from OnePWR Solutions in late September, a deal worth about $3.4 billion that also brings engineering and construction capability to install them. Anthropic did not acquire OnePWR, and neither company responded to Reuters. The report lands as Anthropic prepares its IPO; watch for where the generators are deployed and whether the prospectus mentions them.
