SpaceX Files S-1: The Largest IPO in History at $1.75 Trillion — What Every Investor Should Know
On April 27, 2026, SpaceX's registration statement became public — after the company confidentially filed Form S-1 with the U.S. Securities and Exchange Commission on April 1. If the timeline holds, SpaceX will list on Nasdaq in June 2026 at a target valuation of $1.75 trillion, implying a price of approximately $525 per share.
The fundraising goal: $75 billion. That is triple the Saudi Aramco 2019 record ($29.4 billion) — the largest IPO in the history of public markets.
What an S-1 Reveals About SpaceX
An S-1 is the mandatory registration document a company files with the SEC before an IPO. It contains full financial statements, business structure, risk factors, intended use of proceeds, and terms of the offering.
Key figures from SpaceX's S-1:
| Metric | Data |
|---|---|
| Starlink revenue 2025 | $10B |
| Starlink subscribers | 10M+ |
| Projected SpaceX revenue 2026 | ~$20B |
| Projected SpaceX EBITDA 2026 | ~$14B |
| Target company valuation | $1.75T |
| Share of IPO allocated to retail | 30% |
The Largest IPO in History: The Scale in Context
| Company | Year | Raised |
|---|---|---|
| Saudi Aramco | 2019 | $29.4B |
| Alibaba | 2014 | $25B |
| 2012 | $16B | |
| SpaceX | 2026 | ~$75B |
At $1.75 trillion, SpaceX would immediately rank among the top 5 largest companies in the world by market cap — alongside Apple, Nvidia, Microsoft, and Alphabet.
Why 30% for Retail Is Unusual
In typical IPOs, retail investors receive whatever institutional allocations leave behind — 5–10% of shares at best. SpaceX has reserved 30% of IPO shares for retail buyers. That is nearly unprecedented at this scale.
Key dates for those who want to participate:
- June 8 — roadshow begins (institutional investor presentations)
- June 11 — dedicated retail investor event
How an IPO Works: A Quick Glossary
IPO (Initial Public Offering) — a company's first sale of shares to the general public through a stock exchange.
Underwriter — the investment bank (in SpaceX's case, Goldman Sachs and Morgan Stanley) that organizes the offering, builds the order book, and sets the final price.
Lock-up period — typically 90–180 days after the IPO during which insiders (founders, venture funds) cannot sell shares. Lock-up expiry often creates price pressure as supply increases.
Price discovery — the process by which the market determines the actual trading price in the first days after listing. The IPO price is set by underwriters based on institutional demand; the market can deviate sharply in either direction.
Why the Loudest IPO Is Not Always the Best Entry Point
Academic finance research consistently finds that companies going public at record valuations underperform the market on average over the following 1–3 years. The reason: IPO pricing captures peak enthusiasm and already embeds optimistic scenarios.
The clearest example: Facebook priced at $38 in May 2012 and fell to $17.50 within four months. It then rose to $350+. Investors who bought on IPO day waited years to break even.
SpaceX is an exceptional company. But a $1.75 trillion valuation means the market is already pricing in a very optimistic outcome for Starlink's global subscriber growth and the launch business. Starlink has 10 million subscribers and $10 billion in revenue. Everything else — the path to $20B and $14B EBITDA — is projection.
Practical Takeaway
SpaceX's IPO will dominate financial media in June 2026. If you want to participate: roadshow starts June 8, retail event is June 11. But access to the most high-profile IPO and the best investment outcome are not the same thing. As always, what matters is price relative to value — not the name on the ticker.
