SpaceX advances IPO process with unconventional fixed-price structure

The aerospace giant is skipping the traditional bookbuilding playbook entirely, setting a fixed price of $135 per share in what could become the largest IPO in history.

SpaceX is preparing to go public on Nasdaq under the ticker SPCX with a pricing mechanism that Wall Street has never seen at this scale. The company has set a fixed price of $135 per share, bypassing the standard bookbuilding process where banks gauge investor appetite before settling on a number.

The offering aims to raise approximately $75 billion through the sale of 555.6 million shares. If successful, that would imply a post-IPO valuation of roughly $1.75 trillion, eclipsing the record set by Saudi Aramco’s 2019 debut.

How the “autonomous IPO” works

SpaceX filed its public S-1 prospectus with the SEC on May 20, 2026, following an earlier confidential submission. Roadshow marketing kicked off on June 4, with pricing expected after market close on June 11 and trading set to begin June 12.

The key difference: there’s no price range to haggle over. The $135 figure is the number, take it or leave it. Market analysts have called this the “first autonomous IPO,” a label that captures both the novelty and the sheer audacity of telling the market what you’re worth rather than asking.

Goldman Sachs is among the lead underwriters, and the deal is expected to include a significant retail allocation.

Why $1.75 trillion is a staggering number

To put the implied valuation in perspective, $1.75 trillion would place SpaceX in the same neighborhood as the most valuable public companies on Earth. Saudi Aramco’s 2019 IPO raised roughly $25.6 billion and was considered a once-in-a-generation event. SpaceX is targeting three times that amount.

What this means for investors

In a fixed-price model, pricing risk shifts squarely to the buyer. You’re paying $135 per share because SpaceX says so, not because a market-clearing mechanism arrived at that number.

For retail investors who have historically been locked out of mega-IPOs, the significant retail allocation is a genuine shift. Whether that allocation proves to be a gift or a trap depends entirely on where the stock trades in the weeks and months after June 12.
