It’s been a year since billionaire tech entrepreneur Elon Musk left his informal position in President Trump’s White House in May 2025. But behind the scenes, Musk has been busy.

Musk has spent the last few weeks in a California courtroom, where he is suing his former business partner, OpenAI CEO Sam Altman. In January, Musk applied for permission with the US government to launch a million satellites into orbit, some of which he says will serve as solar AI data centres. And he is preparing to take his company SpaceX public, with an estimated valuation of over $1 trillion.

Though his political presence has waned, is it possible that Elon Musk is more powerful than ever? We speak to the BBC’s North America technology correspondent Lily Jamali about what the world’s richest man has been up to since leaving the White House.
