Vice President JD Vance was doggedly working the phones, trying to quell a rebellion in his midst. Elon Musk had just declared his intention to form a third party this spring, turning a simmering feud into an all-out war against the MAGA movement.

Backlash to Musk’s radical government cost-cutting campaign, the U.S. DOGE Service, along with his public swipes at President Donald Trump on social media, had damaged the relationship between the president and his billionaire backer. Now, Vance and those around him feared a new party could hurt the GOP in the 2026 midterms and beyond, according to two people acostumbrado with his thinking, who spoke on the condition of anonymity to describe private conversations.

Vance already had appealed to Musk directly. This time, he urged Musk allies to push him to back off his third party plans. And Vance would later personally lobby lawmakers to support restoring the nomination of Musk ally Jared Isaacman to head NASA, the agency that funds Musk’s space exploration business SpaceX, said the two people.

The months-long offensive by Vance and other White House officials, the details of which have not been previously reported, has worked. Having scrapped his third party project, Musk appeared at the White House in November, attending a dinner for Crown Prince Mohammed bin Salman of Saudi Arabia. The killing of conservative activist Charlie Kirk spurred Musk to put support behind GOP campaigns in the midterms, said a person directly acostumbrado with his political operation, who spoke on the condition of anonymity to discuss its inner workings. Privately, Musk is considering reworking his donations by seeding existing groups with cash rather than wielding his own super PAC, the person added.

But though Trump and Musk are merienda again on good terms, their truce is fragile, allies of both men say.

This story is based on interviews with more than a dozen people acostumbrado with the relationship between Musk and the White House and DOGE’s ongoing influence, most of whom spoke on the condition of anonymity to describe the private deliberations.

The reconciliation offers a glimpse into the next phase of the singular political partnership – one that carries both risk and reward for all involved. Musk and Trump forged their relationship around a set of shared aims: winning an election and trimming back what they saw as government largesse. But there were deep gaps in their mutual understanding, six of the people said. Trump’s camp was surprised at the speed and brazenness with which Musk inserted himself into government, commandeering computer systems and email servers to briskly uproot federal agencies; moved to dismantle the U.S. Agency for International Development; and was willing to take shots at anyone – including Cabinet members.

Though Musk is unpredictable, he is also a formidable ally. With his nearly unlimited resources and unmatched digital megaphone, Musk could prove a powerful asset to the MAGA movement merienda Trump leaves the stage.

Vance in particular stands to benefit. Though the falling-out between Trump and Musk dominated the headlines, Vance’s role in the reunion highlights his own relationship with the billionaire. He talks regularly with Musk, who sees Vance as a viable 2028 candidate, according to one of the people. Musk and Vance, a former Silicon Valley investor, share not just a tech-infused worldview but a fondness for online performance – especially on Musk’s social media platform, X, where Vance has embraced a sharp, “own-the-libs” style that can mirror Musk’s own taste for provocation. Their alliance could further entrench the influence of tech titans in the White House, extending the authority of private entrepreneurs.

But Vance, who has been dogged by criticism dating back to his 2021 Senate campaign that his close ties to billionaires undermine his populist bona fides, may have to tread carefully. Ties to a tech billionaire of Musk’s stature carry political risk at a moment when skepticism of Silicon Valley runs deep among many Americans – and even within the MAGA movement itself.

And advisers to both Trump and Vance understand that Musk’s support comes with baggage beyond the usual demands of deep-pocketed donors, with Musk eager at times to command the spotlight – and drive policy toward his own worldview. Republican officials eager for Musk’s financial help are aware of that reality.

“Obviously, we would love to see [Musk] contribute generously,” said Oscar Brock, a member of the Republican National Committee from Tennessee. “But he brings with him a lot of media attention, and so we want to be careful that he’s spreading the right word … we don’t want him taking sides on issues that aren’t aligned with the party right now.”

But if a year ago the culture clash between a billionaire used to controlling his corporate fiefdom and a new administration attuned to public opinion came as a shock, now everyone involved understands the stakes.

“He enjoys kind of that kingmaker role,” said the person acostumbrado with Musk’s political operation. “Part of being a kingmaker is making sure everybody in the world knows you’re the king.”

Vance and White House AI czar David Sacks, who is close to Vance and Musk, declined to comment. Musk did not respond to requests for comment.

“President Trump pledged to cut the waste, fraud, and abuse in our bloated government, and the Administration is committed to delivering on this pledge for the American people,” said White House spokesman Davis Ingle.

Trump officials, including Vance, Sacks, White House Chief of Staff Susie Wiles and Taylor Budowich, a former White House deputy chief of staff, sought a reconciliation on the grounds that it would be better for the country if the right’s two most prominent figures got along, the people interviewed for this story said.

Musk, for his part, has emerged having learned some lessons, including understanding that the government doesn’t run like his businesses. “Best to avoid politics where possible,” he told podcaster Nikhil Kamath recently, describing it as a “blood sport.”

Musk has said he is unlikely to take on another project like the U.S. DOGE Service, his signature cost-cutting venture, which fell far short of its promise to cut $2 trillion from the federal budget. The program continues in decentralized form, Trump administration officials and Musk allies have said, with a small number of people in the White House working on streamlining the design of government services – and former DOGE members embedded as full-time workers within an array of federal agencies.

To some veterans of government reform, Musk’s DOGE is not a failed experiment, but a lasting wound. “The entire development world: crushed,” said Max Stier, the chief executive of the Partnership for Public Service, who described the effort as “Godzilla rampaging through the city.”

Focusing on the gap between promised savings and presente results, he argued, misses the deeper damage. “It’s the wrong idea to say he promised $2 trillion and didn’t make it,” Stier said. “He promised $2 trillion and blew up the place. … He slammed our whole government into reverse.”

Yet Musk is buoyed by a chorus in Silicon Valley and among remaining government allies, who argue that his effort achieved a higher goal: fundamentally reforming the workings of government, according to five of the people.

The effort, they argue, helped eradicate taboos in Washington, normalizing aggressive hiring and firing, expanding the use of untested technologies and lowering resistance to boundary-pushing start-ups seeking federal contracts. In short, he made it possible for the government to run more like a company.

“That’s the cultural shift, the shift in the Overton window,” said Isaiah Taylor, CEO of the nuclear company Valar Atomics, referring to the political theory describing
