The biggest IPO in history may be just weeks away. SpaceX has filed its S-1 with the SEC and is targeting a June 12, 2026 listing on the Nasdaq under ticker SPCX with a valuation of up to $1.75 to $2 trillion.
So What Is SpaceX?
SpaceX is a private aerospace and technology company founded by Elon Musk in 2002. It has grown with several distinct business lines:

- Falcon 9 & Launch Services: Reliable and reusable orbital rocket. SpaceX has dramatically reduced the cost of reaching orbit and holds major contracts with NASA and the US Department of Defense.
- Starlink: A global satellite internet constellation with thousands of satellites in low Earth orbit. Starlink is SpaceX's primary revenue engine, serving millions of subscribers worldwide including remote areas, maritime, and aviation.
- Starship: A next-generation super-heavy launch vehicle designed to carry large payloads to the Moon, Mars, and beyond. Still in development, but considered a transformational commercial opportunity.
- xAI & Grok: In early 2026, SpaceX acquired xAI. Elon Musk's artificial intelligence company which itself had previously acquired X (Twitter). This makes SpaceX a combined aerospace, internet, and AI business heading into its IPO.
How the SpaceX IPO Is Structured
The IPO has two key components:
- 66% Primary Shares: Newly issued shares where the proceeds go directly to SpaceX. This capital funds the company's ongoing operations, Starship development, and Starlink expansion.
- 33% Vendor Shares: Existing shares sold to insiders, employees, early investors, and founders. The proceeds from these go to the sellers, not SpaceX itself.
The planned raise is up to $75 billion. Of that, approximately $22.5 billion — or 30% — is reserved for retail investors. That is roughly three times the typical retail allocation seen in large IPOs, which is usually around 10%.
The Question Investors Should Be Asking
Is the unusually large retail allocation a generous gesture or a warning sign?
There are two possible readings:
- The optimistic view: Management wants to share the upside with everyday investors. A broad retail base also creates loyal long-term shareholders and brand advocates.
- The cautious view: A 30% retail allocation may signal that institutional investors, the sophisticated buyers who do deep due diligence haven't filled the book at a $2 trillion price tag. When institutions pass, retail fills the gap. And retail investors tend to be more driven by excitement than fundamentals.

This is worth sitting with. Looking into SpaceX operating and financial data, it's obvious which segment is profitable and which is in its pre revenue stages.
While the Space and Starlink businesses generate real cash ($653 million and $7 billion in Adjusted EBITDA respectively), the AI segment is burning through capital at an alarming rate, losing $1.2 billion on an adjusted basis.
And the business which is valued at up to around 94 times revenue. It’s a multiple that demands exceptional long-term growth to justify. Great business. Expensive price.
Final Thoughts
SpaceX is a genuinely extraordinary business, arguably the most ambitious company operating today. But extraordinary businesses can still be overpriced stocks at IPO.
Understand what you're buying, ask why the deal is structured the way it is, and don't let excitement override analysis. The 30% retail allocation is worth scrutinising and not dismissing.
For most investors, the most sensible path is to wait for the IPO, evaluate the opening price against the fundamentals, and consider whether $2 trillion is a price you're genuinely comfortable paying for SpaceX's future.
