Anthropic joins AI’s natural gas frenzy, buys $3.4B worth of turbines

Anthropic is spending $3.4 billion on Caterpillar natural gas generators capable of producing up to 1.7 gigawatts of electricity, buying units that equipment supplier OnePWR had originally ordered, according to a Financial Times report. The purchase marks a shift for Anthropic, which has generally rented rather than bought infrastructure and disclosed in its S-1 filing that it pays xAI $1.25 billion per month through May 2029 for computing power. Natural gas turbine backlogs stretch into the early 2030s and grid connection queues can be just as long, and the report says OnePWR ordered the turbines a couple years ago but couldn't find financing to complete the purchase.
