Jamie Dimon called Elon Musk the 'Edison of our time' as JPMorgan hosted SpaceX's $75 billion IPO road show -- and even invited Musk's mom

As Elon Musk prepares for what will likely be the biggest listing in history, some top-tier bankers assisting with SpaceX's public debut are lining up to sing Musk's praises ahead of the big day.

SpaceX is targeting a price of $135 per share when the company goes public -- which could happen as early as next week. Such pricing could raise a record-setting $75 billion, and potentially turn Musk into the world's very first trillionaire. A successful IPO would also likely be very good business for the legion of banks gearing their investors up for a potentially blockbuster series of public listings throughout the rest of the year. And one unlikely ally on his side is JPMorgan Chase CEO Jamie Dimon, who, despite their public feud years ago, is now singing Musk's praises.

"Elon is the Edison of our time," Dimon said during a virtual interview with Musk Thursday, part of a road show event hosted by the bank at its Manhattan headquarters and attended by several thousands of the bank's high-net-worth clients.

"It's been an extraordinary 24 years watching Elon grow over time, and now making a massive leap into the future," Dimon said during the event. The interview opened with an in-person special guest appearance by his mother, Maye Musk, who similarly lavished praise on her son, noting his seemingly prodigal vision of the future as a child.

"When you were 3 years old, and I told people, 'I have a genius son,' they would roll their eyes," she said. "When you said you wanted to start with rockets, then I rolled my eyes. And then, you did it."

A congratulatory introduction from his mother is one thing, but Dimon's words might have surprised Musk just a few years ago. The pair were involved in a well-publicized feud -- that included a $162 million lawsuit filed by JPMorgan against Tesla, Musk's electric car company, in 2021 over an alleged contract breach regarding stock warrants. The bank dropped its lawsuit last year.

But Dimon started putting on a charm offensive as early as the World Economic Forum meeting in January of this year, well before SpaceX's lucrative IPO was a reality. "The guy is our Einstein," Dimon said of Musk during a CNBC interview at Davos, adding that the two had patched up their disagreement.

"I'd like to be helpful to him and his companies as much as we can," Dimon said. In April, SpaceX would go on to confidentially file for an IPO.

To navigate the blockbuster offering, SpaceX has tapped some of Wall Street's most elite names to underwrite, publicize, and advise on the entire affair. Earlier this year, SpaceX reportedly was working with at least 21 banks in preparation for the IPO, including heavyweights such as JPMorgan Chase, Morgan Stanley, Goldman Sachs, and Bank of America. Over the past few months, these institutions have taken on the job of pitching investors, distributing shares ahead of the public listing date, and creating buzz for the company and its mission.
