President Donald Trump mocked Elon Musk’s newly formed third party, describing it as ‘ridiculous’ and remarked on his disappointment in seeing his former first ally go ‘entirely off the rails.’

Trump said Musk’s America Party would ‘never work’ as the world’s richest man carried out his threat to challenge the two-party system. 

‘Have fun,’ Trump said in response. 

And, in a lengthy post on his Truth Social account, Trump accused Musk of going ‘completely off the rails.’ 

‘I am disheartened to observe Elon Musk completely “off the rails,” essentially turning into a TRAIN WRECK in the last five weeks. He even aims to launch a Third Political Party, ignoring the fact that they have never been successful in the United States.’

In response to Trump’s remarks about a ‘big, beautiful bill,’ Musk formally registered his ‘America Party’ with the Federal Election Commission by filing a Statement of Organization on Sunday.

Trump, asked about it, went off on his former ‘first buddy.’ Musk, the world’s richest man, spent millions helping Trump win a second term in the White House. 

‘I think it’s ridiculous to start a third party,’ Trump told reporters in New Jersey on his way back to the White House after a weekend at his Bedminster golf club.

‘We have a tremendous success with the Republican Party. The Democrats have lost their way, but it’s always been a two party system, and I think starting a third party just adds to confusion. It really seems to have been developed for two parties. Third parties have never worked, so he can have fun with it, but I think it’s ridiculous.’ 

Musk vowed vengeance after Congress passed Trump’s signature legislation to fund the government. 

The Tesla founder was angry it contained no federal subsidies for electronic vehicles. And Musk was furious the legislation added to the country’s debt. During his time at the Department of Government Efficiency, Musk worked to cut the size and scope of the federal government.

But Trump said Musk knew all along he wouldn’t get a subsidies. 

‘When Elon gave me his total and unquestioned Endorsement, I asked him whether or not he knew that I was going to terminate the EV Mandate – It was in every speech I made, and in every conversation I had. He said he had no problems with that – I was very surprised!,’ he wrote in his Truth post. 

As lawmakers debated Trump’s legislation, Musk – the bill’s biggest critic – threatened them repeatedly with primaries and then vowed to start his own political movement.

It passed last week and Trump signed it into law on the Fourth of July. 

And, this weekend, Musk carried out his threat.

‘When it comes to bankrupting our country with waste & graft, we live in a one-party system, not a democracy,’ he wrote Saturday on X. 

‘Today, the America Party is formed to give you back your freedom.’ 

Musk spent almost $300 million supporting Trump and Republicans in the 2024 election. 

He and Trump started out close with the president even inviting Musk to stay in the Lincoln Bedroom at the White House. 

But duo got into a social media war during debate on the ‘big, beautiful bill,’ leading to Musk threatening to use his billions to start a third political party and Trump threatening to deport the naturalized American citizen.

Musk could impact the 2026 midterm elections that determine control of Congress if he is willing to spend significant amounts of money. 

However, starting a third party has its difficulties. Every state has different requirements to put a candidate on the ballot and the heavily-gerrymandered congressional districts could prove hard for a third-party candidate to penetrate.  

Republicans currently hold slim majorities in both the House and Senate with just a handful of seats giving them the edge over Democrats.

Out of 100 seats in the U.S. Senate, 53 are held by Republicans. In the U.S. House of Representatives, 220 seats are held by Republicans and 212 are held by Democrats with three seats presently vacant due to members passing away.

The margins could easily shift with a few well-placed victories. 

The world’s richest man spent Sunday morning on X taking feedback from users about the party. He indicated he was going to use it in next year’s contests.

He also vented his anger at Republicans. 

‘The Republican Party has a clean sweep of the executive, legislative and judicial branches and STILL had the nerve to massively increase the size of government, expanding the national debt by a record FIVE TRILLION DOLLARS,’ he wrote on X. 

And he vowed to crack America’s politics.

‘The way we’re going to crack the uniparty system is by using a variant of how Epaminondas shattered the myth of Spartan invincibility at Leuctra: Extremely concentrated force at a precise location on the battlefield,’ Musk wrote.
