Elon Musk has acquired APR Energy, a Jacksonville-based builder of fast-deployable mobile power plants, in a transaction that surfaced through regulatory paperwork rather than any announcement from the parties involved.

The Elon Musk APR Energy acquisition, valued at more than $1 billion, hands the billionaire direct ownership of a fleet of trailer-mounted gas and diesel turbines capable of generating over 1 gigawatt of electricity, reportedly destined to power the data centres behind xAI's Grok chatbot.

The deal matters because it shows how far AI companies will go to secure electricity, and how much of that race now happens outside public view.

There was no press release from Musk, otherwise among the most prolific announcers of his own news.

The deal came to light through a Federal Trade Commission early termination notice, transaction number 20261350, dated 14 May 2026, which lists Musk as the acquiring party and New APR Energy LLC as the acquired entity.
