“The public has given us a mandate that could not be more clear, the clearest mandate. The people have spoken. The people want change,” Musk told the audience of Trump’s biggest donors, campaign leaders and appointment seekers. “We are going to shake things up. It’s going to be a revolution.”

Musk’s attachment to Trump has created an alliance between America’s most powerful politician and its richest businessman — and roughly the same percentages of Americans have favorable views of each, according to a new poll from the AP-NORC Center for Public Affairs Research.

Experts are split on whether that overlap in public opinion is a good or bad thing for Musk’s businesses or for Trump’s politics. But it could have far-reaching effects in both realms.

Musk, whose net worth tops $400 billion, oversees six businesses while continuing to work closely with Trump: electric car manufacturer Tesla, the X social media platform, space technology company SpaceX, brain link company Neuralink, the startup xAI and tunneling operator The Boring Co.

“Even though there’s a negative impact, in terms of potentially alienating some of their customers that might not be fans of Trump, the benefits far outweigh any negatives when it comes to having a right-hand seat next to Trump in the White House,” said Dan Ives, an analyst at Wedbush Securities.

Ross Gerber, CEO of Gerber Kawasaki Wealth and Investment Management, identified himself as an investor in Musk’s Tesla and a driver of Tesla’s new Cybertruck, the futuristic pickup that has gotten huge amounts of attention but also been the subject of safety concerns and multiple recalls.

“Having your CEO not working at your company and working at the job of having to fire government employees … as a shareholder, I’m paying someone to not work for my company,” he said. “As a Cybertruck owner with self-driving that sucks and doesn’t work, I’m like, ‘Dude, this isn’t fair.’”

But despite his skepticism, Gerber said he won’t stop investing in Musk’s businesses.

“I’ve made a lot of money with Elon,” he said. “I’m not in the business of investing based on the popularity of CEOs.”

Musk’s favorability is similar to Trump’s

Musk doesn’t appear to give Trump much boost with people who don’t back the incoming president.

He is no more popular with the U.S. public than the president-elect himself, and viewed unfavorably by about half of Americans, according to the AP-NORC poll.

About 4 in 10 Americans have a somewhat or very favorable view of the world’s richest person, very similar to the percentage who view Trump positively. Likewise, about half of adults have a somewhat or very unfavorable view of Musk — again, similar to Trump.

Instead, said one political strategist, Musk is the ideal validator for someone who cultivates an image of success in business and who has stocked his Cabinet and key adviser roles with billionaires.

“Trump has always pushed this narrative that he’s a successful developer and a very successful businessman. I think having Musk with him is his double-down on this business success, good-for-the-economy, good-for-everybody-making money kind of persona,” said Christine Matthews, a national political pollster who has worked for Republicans. “In this case, Musk is seen as this successful, innovative, tech entrepreneur, frontier-buster.”

Musk also has at his disposal X, the social media platform formerly known as Twitter that he purchased and turned into a megaphone for conservative ideas. And having spent an estimated $250 million to support Trump in the election, Musk has signaled he is willing to back Republican primary challenges to GOP members in the House and Senate seeking reelection in 2026 who waver on Trump’s appointments and agenda.

Trump has tasked him with leading a group to reduce the size of the federal government and reduce the rulemaking authority of the federal bureaucracy.

Musk retains a wide array of businesses

Tesla stands to make significant gains under a Trump administration with the threat of diminished subsidies for alternative energy and electric vehicles doing the most harm to smaller competitors. Trump’s plans for extensive tariffs on Chinese imports make it less likely that Chinese EVs will be sold in bulk in the U.S. anytime soon.

Some analysts believe the billionaire’s role will create a very friendly landscape for Tesla over the coming years. Ives, the analyst at Wedbush Securities, said Musk’s relationship with Trump could “revolutionize the Tesla story, especially around robotics, AI and autonomous.”

Investors, he said, are betting on Musk and see his political ascent as a “champagne moment.” Unlike Gerber, Ives believes that ending the EV credit and taking subsidies from Detroit carmakers, Hyundai and other companies will create only opportunity for Tesla.

“I think Wall Street is starting to fully digest the potential benefits from Musk,” Ives said.

Tesla shares closed at a record high on Tuesday, with much of the company’s recent gains coming after Trump’s victory. But Gerber feels that jump is because investors believe Tesla will have an advantage when it comes to autonomous driving because Trump could grant the company a national autonomy license.

Still, he thinks Tesla will be the “big loser” of Musk’s businesses because of Trump’s promise to end the EV tax credit for carmakers.

“For Tesla, I don’t see a ton of benefit from this,” he said. “Elon is misleading people to say it hurts the competition if the credit goes away.”

Musk’s other companies — including his artificial intelligence company, xAI — could reap the benefits of working within the Trump administration, he said.

“AI is a transformative investment that will create lots of regulatory and governmental issues, especially around safety and information,” Gerber said. “There’s a lot of benefit, from an AI perspective, to having Elon where he is.”

The relationship between the two men has no parallel in U.S. history, said David Nasaw, biographer of American business tycoons Andrew Carnegie and William Randolph Hearst. He noted that Musk, to a level unlike other tycoons, has relied on subsidies and favorable government decisions for his success from Tesla to SpaceX.

“He’s a unicorn,” Nasaw said of Musk.
