Musk acquired APR Energy through an FTC filing dated May 14, 2026, with the deal valued at over $1 billion based on a 5% stake sale.
APR Energy operates mobile gas and diesel turbines that can be installed in days and reach full power in under 10 minutes.
The acquisition comes as xAI's data centers have been running on unpermitted gas turbines, with lawsuits filed under the Clean Air Act.
