SpaceX is preparing to go public in what would be the largest IPO ever attempted, targeting $75 billion in proceeds by offering roughly 555.6 million shares at $135 each. If it pulls this off, the company would hit a valuation of approximately $1.75 trillion on day one.

For context, the current record holder for largest IPO is Saudi Aramco, which raised $29 billion when it debuted in 2019. SpaceX is aiming to more than double that. And in a move that breaks sharply from Wall Street convention, up to 30% of available shares would be allocated to retail investors, worth somewhere in the neighborhood of $22.5 billion to $23 billion.

A retail allocation that rewrites the playbook

Typical mega-cap IPOs reserve somewhere between 5% and 10% of shares for individual investors. The rest goes to institutional heavyweights: pension funds, hedge funds, sovereign wealth funds. SpaceX is tripling that floor, setting aside nearly a third of its offering for regular people with brokerage accounts.

Major brokerages are reportedly facilitating access. Robinhood, Fidelity, and Charles Schwab are among the platforms expected to offer shares, with some lowering minimum account requirements to widen participation.

Demand is already outpacing supply

Ahead of the roadshow that launched in early June 2026, investor demand for SpaceX shares reportedly surged to around $150 billion. That’s roughly double the $75 billion fundraising target, suggesting the offering could be significantly oversubscribed before the first trade even executes.

The company plans to list on the Nasdaq under the ticker SPCX, with trading expected to begin as soon as June 12, 2026. An IPO prospectus was filed with the SEC, and the roadshow commenced in early June to drum up interest from both institutional and retail buyers across the globe.

The xAI merger changes the calculus

SpaceX isn’t going public as purely a rocket company. In February 2026, the company merged with xAI, Elon Musk’s artificial intelligence venture. The combination created an entity that spans space exploration, satellite internet via Starlink, and AI research and data center operations.
