Elon Musk's SpaceX is taking over his artificial intelligence (AI) start-up, as the billionaire continues to unify some of his many business interests.
SpaceX confirmed the deal to acquire xAI, a smaller firm known for its Grok chatbot, posting a memo from Musk about the merger on its website.
In the note, Musk said the combination would form an innovation engine putting AI, rockets, space-based internet, and media under one roof.
Terms of the deal were not disclosed. However, a source familiar said it valued xAI at $125bn (£91bn) and SpaceX at $1tn, making it the most valuable private company ever.
Last month, Musk's electric car company, Tesla, announced it had invested $2bn into xAI.
Musk told Tesla investors at the time that he envisioned xAI functioning as an orchestra conductor for Tesla factories employing autonomous robots.
SpaceX is also reported to be working on plans to list its shares for public trading.
Emily Zheng, a senior analyst at Pitchbook, said the deal for xAI has all the markings of a company preparing for a public listing.
In the SpaceX memo announcing the xAI merger, Musk said he thought space would provide the solution to the energy needs faced by AI firms.
He said launching AI satellites from Earth would be the immediate focus, but added that the deal would also help advance his bigger ambitions.
The capabilities we unlock by making space-based data centers a reality will fund and enable self-growing bases on the Moon, an entire civilization on Mars and ultimately expansion to the Universe, he wrote.
