In late September, Piper Sandler said it had advised OnePWR Solutions on the sale of a power-generation platform to an unnamed “frontier AI lab.” That buyer has now been identified as Anthropic, which is committing $3.4 billion for 1.7 gigawatts of heavy-duty natural-gas generators originally tied to Caterpillar orders.¹

The equipment is expected within two years, along with engineering and construction support. For Anthropic, which has historically leaned on partners including AWS, Google Cloud, Nvidia and AMD, the move marks a more muscular effort to lock down the physical backbone of its computing expansion. Its planned “Anthropic Direct” model is meant to reserve data-center capacity early, while postponing the much larger accelerator purchases until demand is clearer.¹

Yet the deal is also a sign of constraint, not simply ambition. Anthropic’s own filing warns that turbines, transformers and substations can take years to obtain, while limited production and tariffs raise costs. It also cautions that greater reliance on gas-fired generation will intensify competition for fuel and pipeline capacity: “we expect increased competition among users for the same natural gas supply and pipeline capacity.”¹

A second account casts the purchase more bluntly. With turbine backlogs extending into the early 2030s and grid-connection queues similarly clogged, Anthropic appears to have seized scarce equipment that OnePWR could not finance—reportedly going straight to Caterpillar rather than allowing capacity to fall into a rival’s hands.²

That urgency is spreading across Big Tech. Google, Amazon, Microsoft and Meta have pursued dedicated power arrangements, while xAI has used gas turbines after grid connections proved inadequate. The prize is speed and control; the trade-off is exposure to a fuel market that could turn expensive fast. One analyst cited in the report expects gas prices in some markets could more than triple by decade’s end.²
