Anthropic, developer of the Claude AI assistant, closed a US$3.4 billion agreement to secure power for its AI data centers. The deal with OnePWR Solutions covers gas generators with total capacity of 1.7 gigawatts. It was completed in late September and reported by the Financial Times.
Deal structure
Anthropic took over existing generator orders from OnePWR instead of contracting it as a supplier. OnePWR had placed the orders with Caterpillar two years earlier but needed financing to complete the purchase. The move gave Anthropic access to equipment ordered before prices rose, with deliveries expected in the short term and over the next two years.
Computing commitments
Anthropic said it holds almost US$900 billion in computing capacity commitments through 2045. It has mainly relied on partners for chips, land, data centers, and electricity. The company is also preparing for a possible public listing in November, according to the Financial Times.
Direct power supply
The gas generators will provide electricity directly to Anthropic's data centers. The agreement includes engineering and construction services needed to install the equipment. Anthropic did not buy OnePWR and no employees transferred as part of the deal.
Other large AI developers are also buying power equipment. xAI bought US$2 billion in mobile gas turbines this year. Alphabet acquired energy developer Intersect in late 2025.
