SpaceX is moving closer to what could be one of the largest stock market debuts ever by valuation.
The rocket and satellite company founded by Elon Musk has publicly filed its IPO prospectus with the US Securities and Exchange Commission. It will list under ticker symbol SPCX on the Nasdaq.
The company rests on three major pillars: space launches, Starlink satellite internet, and artificial intelligence. Of those, Starlink appears to be the clearest profit engine.
SpaceX generated $4.69 billion in revenue in the first quarter of 2026, but posted an operating loss of $1.94 billion. Its connectivity business, powered by Starlink, generated operating profit of $1.19 billion. Its AI division lost $2.47 billion on $818 million of revenue.
Starlink gives SpaceX recurring revenue and a strong position in satellite broadband. The network has about 10,000 satellites serving consumer, government, and enterprise customers. But the filing also shows how aggressively SpaceX is spending on AI, following its merger with Musk’s xAI business earlier this year.
That makes the IPO more complicated than a simple bet on rockets.
Investors are being asked to back a company with a proven role in commercial space, a profitable satellite internet arm, and a much more expensive AI ambition.
The prospectus also underlines how much control Musk will keep. Reuters reported that he will hold 85.1% of SpaceX’s combined voting power after the offering. Public investors would own shares in the company, but they would have limited influence over its direction.
Then there is Mars.
Part of Musk’s SpaceX compensation is tied to the establishment of a permanent human colony on Mars with at least one million inhabitants. That target captures the company’s long-term ambition. It also shows how unusual this IPO is. Most companies go public with projections about revenue, margins, and market share. SpaceX is also asking investors to consider a future that includes human settlement beyond Earth.
The timing has helped keep attention on the company’s space ambitions. SpaceX’s upgraded Starship test flight on May 22 hit most of its major targets, including a controlled splashdown in the Indian Ocean. Starship is central to Musk’s long-term plans for the moon and Mars.
For investors, the question is whether its future profits can justify a valuation that would place it among the world’s most valuable companies from day one as a public business.
To do that, SpaceX may need Starlink to keep growing, AI to become profitable, and investors to keep believing in Musk’s ability to turn extreme ambitions into working businesses.
For now, the filing shows a company of huge scale, huge spending, and huge control concentrated in one person’s hands. That may be exactly what excites some investors, but it may also be what worries others.
