SpaceX has formally laid out the terms for what is being billed as the biggest IPO ever, with investors offered 555.6 million Class A shares at $135 each and a headline valuation of $75 billion before any greenshoe-style extra allotment is added. Trading is set to start on June 12, 2026, on both the Nasdaq Global Select Market and Nasdaq Texas under the ticker SPCX, with the deal expected to close on June 15 if the usual closing conditions are met.
The structure is familiar Wall Street machinery, but the scale is anything but. Underwriters also have a 30-day option to buy another 83.3 million shares at the IPO price, which could lift proceeds by roughly $11.25 billion if demand runs hot enough. That kind of oversubscription buffer is standard in blockbuster offerings; what is rare is a company arriving at public markets with rocket launches, satellite broadband, and data infrastructure ambitions all packed into one story.
IPO size and listing details
The offering is being arranged by an unusually deep bench of banks: Goldman Sachs, Morgan Stanley, Bank of America, Citigroup, J.P. Morgan, Barclays, Deutsche Bank, UBS, and Wells Fargo. SpaceX says the transaction will use the Nasdaq listings as the trading venues, a signal that it wants maximum liquidity and visibility from day one rather than a soft landing on a smaller exchange.
At $75 billion, the base deal already dwarfs prior listings. Saudi Aramco’s 2019 debut raised $25.6 billion, which means SpaceX is effectively trying to reset the IPO scoreboard by a wide margin. If the optional shares are fully taken up, the total cash raised would move even further into a category that public markets rarely get to see, especially outside banking mega-deals.
What SpaceX is selling investors
In its prospectus, the company leans on its long operating history, saying it was founded in 2002 and now sits among the largest players in the global space industry. That pitch is more than branding. SpaceX is not selling a single rocket business; it is bundling launch services, crewed spacecraft, satellite communications, and infrastructure tied to artificial intelligence and data processing into one public-market wrapper.

A record IPO and a very public test
The real question is not whether the IPO is large. It clearly is. The question is whether public investors are ready to price a company whose valuation has been driven by both old-fashioned launch economics and the newer dream of owning the rails for space-based communications and computing. If the debut lands well, SpaceX will have proved that private-market superstardom can survive contact with the public market. If it does not, that $75 billion headline will age quickly.
