Elon Musk, an ex-ally of US President Donald Trump, says he has launched a new political party in the United States to challenge what the tech billionaire described as the country’s “one-party system.”

The world’s richest person — and Trump’s biggest political donor in the 2024 election — had a bitter falling out with the president after leading the Republican’s effort to slash spending and cut federal jobs as head of the so-called Department of Government Efficiency (DOGE).

Musk has clashed with Trump over the president’s massive domestic spending plan, saying it would explode the US debt, and vowed to do everything in his power to defeat lawmakers who voted for it.

Now he has created the so-called America Party, his own political framework, through which to try and achieve that.

Musk cited a poll — uploaded on Friday, US Independence Day — in which he asked whether respondents want independence from the two-party that has dominated US politics for some two centuries.

The yes-or-no survey earned more than 1.2 million responses.
