Anthropic buys $3.4bn of gas generators for data centres
Anthropic has agreed to pay $3.4bn for 1.7 gigawatts of gas-fired generators, the biggest known single power-equipment purchase by an AI company.

Anthropic has agreed to pay $3.4bn for gas-fired generators to power its data centres, the Financial Times reported on Sunday. The paper called it the biggest known single purchase of power equipment by an AI company. The deal covers 1.7 gigawatts of large generators, according to one person familiar with it. TNW has not independently confirmed the agreement.
How the deal works
Anthropic signed the agreement in late September with OnePWR Solutions, a power supplier based in San Antonio, Texas. OnePWR had ordered the generators from Caterpillar about two years ago but needed funding to complete the purchase.
Anthropic initially planned to buy electricity from OnePWR. Instead, it took over the equipment orders, along with the work needed to install the machines. It did not acquire OnePWR itself, and none of the supplier's staff moved to Anthropic, the FT said. Where the generators will be deployed is not known.
Both companies declined to comment to the FT, and they did not immediately respond to Bloomberg, which followed up on the report.
Why it matters
The purchase comes as Anthropic prepares for a stock market listing. Its amended IPO filing last week showed $895bn in commitments, almost all of them for computing power and infrastructure. Owning generating capacity directly would give the company a more direct route to the electricity its data centres need.
Anthropic is not the only AI firm turning to gas to bring data centres online quickly. Elon Musk's xAI faces a lawsuit over gas turbines at its Memphis site, a reminder that on-site fossil power can bring legal and environmental scrutiny alongside speed.
