JPMorgan CEO Jamie Dimon praised companies such as SpaceX and emerging space startups for pushing innovation forward as Wall Street's capital markets rebound.

"I visited SpaceX, it’s extraordinary what they've done. I wish these guys the best. They are investing in stuff that will change humanity for the better," Dimon said during the Reagan National Economic Forum.

When asked how SpaceX's upcoming IPO relates to what is happening within the broader IPO market, Dimon noted that "markets are wide open."

Dimon's broader point was that the machinery of capital markets is moving fast again. 

"ECM is kind of the tip of the spear," he noted, describing how equity capital markets tend to react first when sentiment improves — and how quickly that enthusiasm can reverse. In his view, IPOs, mergers and broader financing activity are less about steady structural trends and more about shifting waves of confidence.

Dimon pointed to the sharp swing in IPO activity as a reminder of how fragile that backdrop can be.

"In 2022, we had 400 IPOs in America, and the next time we have 20. It was dramatic like that. That is often based on sentiment, short-term values, specific stocks themselves," he said, underscoring how quickly issuance can collapse when sentiment shifts. 

At the same time, Dimon emphasized that today's environment feels unusually open. Debt markets are active, M&A is "booming," and equity issuance is returning. That combination has revived appetite for high-growth, capital-intensive companies, particularly those operating in sectors like space, AI infrastructure, and advanced manufacturing.

Elon Musk's SpaceX is targeting a valuation of at least $1.8 trillion in what may be the largest IPO ever, down from an earlier goal above $2 trillion.

The cut follows heavy losses from SpaceX's February merger with xAI. The company posted a $4.28 billion net loss in the first quarter of 2026, with AI infrastructure driving most of the burn, according to the S-1 filing.

Investors are piling in anyway. Since mid-December, when Musk first confirmed IPO plans, a net $14 billion has flowed into three mutual funds and four ETFs holding slices of the rocket maker, per Morningstar data via the Financial Times.

SpaceX has reportedly earmarked up to 30% of IPO shares for retail investors, roughly three times the typical mega-cap allocation.
