Elon Musk says he has created a new political party - the America Party - after asking his followers if he should do so in an online poll.
It follows his public falling out with Republican President Donald Trump.
On Friday, the billionaire had asked his followers on X whether a new US political party should be created.
On Saturday evening he wrote on the same platform: "By a factor of 2 to 1, you want a new political party and you shall have it!
"When it comes to bankrupting our country with waste & graft, we live in a one-party system, not a democracy.
"Today, the America Party is formed to give you back your freedom."
He made the announcement just one day after President Trump signed a tax-cut and spending bill into law on Friday, which the chief executive officer of Tesla had fiercely opposed.
Musk backed Trump's election campaign with more than a quarter of a billion dollars, later rewarded with a high profile role running the newly created department of government efficiency (DOGE).
In May Musk left the role, still on good terms with Trump but criticising key parts of his legislative agenda.
After that the attacks ramped up, the feud eventually boiling over in June when Trump said he was "very disappointed in Elon".
Trump earlier this week threatened to cut off the billion-dollar subsidies that Musk's companies receive from the federal government.
