On Saturday, Musk took to his platform, X, to announce the birth of the movement, citing overwhelming support from everyday Americans sick and tired of being trampled by both Democrats and establishment Republicans.

"By a factor of 2 to 1, you want a new political party and you shall have it," Musk wrote.

"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."

The post came shortly after a July 4th-themed poll on X, where Musk asked: "Should we create the America Party?"

A staggering 1.2 million Americans participated in his poll. 65.4% said YES and 34.6% said NO.

Musk wrote, "One way to execute on this would be to laser-focus on just 2 or 3 Senate seats and 8 to 10 House districts. Given the razor-thin legislative margins, that would be enough to serve as the deciding vote on contentious laws, ensuring that they serve the true will of the people."

Musk, who briefly led the Department of Government Efficiency (DOGE) until his departure in May, blasted Trump over the One Big Beautiful Bill, calling it an "insane spending" disaster, claiming it will balloon the national debt by a staggering $3–5 trillion. He vowed to form the America Party "the next day" if the legislation passed.

The tension between Trump and Musk boiled over in early June when the X owner publicly criticized the legislation on his social media platform, prompting the president to fire back by labeling Musk a "big-time drug addict" and hinting at his ketamine use for depression. Trump also threatened to slash billions in federal contracts and subsidies for Musk's companies, including Tesla and SpaceX, a move that sent Tesla's stock plunging 14% in a single day.

Musk retaliated by suggesting Trump's impeachment, alleging without evidence that Trump's name appears in unreleased Jeffrey Epstein files, and even threatening to decommission SpaceX's Dragon spacecraft, though he later backed off.
