The Biggest IPO in History: What SpaceX Going Public Actually Means
A $75 billion fundraise. A $1.77 trillion valuation. A man with 85% of the votes. And a lesson from history that every excited investor needs to read before they do anything at all.
On 12 June 2026, a rocket company lists on the Nasdaq stock exchange. It wants to raise $75 billion — more money in a single day than most countries spend on their entire national health service in a year. At $135 per share, it would be valued at $1.77 trillion, making it the seventh-largest company in the United States before it has traded a single share on a public market.
The company is SpaceX. The man behind it is Elon Musk. And the event is being called, without much exaggeration, the most consequential stock market debut in history.
Whether you are a UK investor with a Stocks and Shares ISA, someone with a workplace pension, or simply a curious person who has been seeing SpaceX headlines everywhere this week — this is worth understanding properly. Because behind the spectacle, there is a genuinely fascinating and complicated story about what markets are, what they reward, and what history tells us about moments exactly like this one.
What's Actually Happening
What you are actually buying — and it is not what most people think
SpaceX has three distinct business lines, and understanding which one is driving the valuation is essential to making sense of why markets are this excited.
The rocket business is what most people picture. SpaceX's Falcon 9 now commands between 60 and 70 percent of the global commercial satellite launch market. It completes over 135 launches per year — matching in a single year the total number of missions NASA's Space Shuttle flew across its entire 30-year lifetime. The cost to launch one kilogram into orbit has fallen from roughly $54,500 with the Shuttle to approximately $2,700 with Falcon 9.
Starlink is the satellite broadband network — and it is the primary reason the valuation is this large. Starlink generated an estimated $12.3 billion in revenue in 2025, representing approximately 70 percent of SpaceX's total revenue, growing at 58 percent year-on-year. In plain terms: if you buy SpaceX stock, you are primarily buying a satellite internet company that happens to also launch rockets.
xAI — Musk's artificial intelligence subsidiary — has also been folded into SpaceX ahead of the listing. One of xAI's first major customers is paying approximately $1.25 billion a month for access to computing infrastructure. Critics argue that absorbing a heavily loss-making AI venture into a space company just before an IPO raises legitimate questions about whose interests are being served.

The History Lesson
What the great IPOs of the past actually looked like — and what they tell us about SpaceX
One of the most powerful things markets do is create mythology. So before anything else, it is worth looking honestly at what the historical record actually shows.

Microsoft · IPO 1986
IPO price: $21 per share
Microsoft went public almost without fanfare. The company was already profitable, already dominant in operating systems, run by a 30-year-old named Bill Gates who owned 45% of it. Nobody called it the IPO of the century at the time.

Amazon · IPO 1997
IPO price: $18 per share
A money-losing online bookshop that analysts widely expected to fail. Bezos warned investors it would not be profitable for years. It lost money for most of its first decade. Anyone who held through that eventually saw one of the most extraordinary wealth-creation events in history.

Google (Alphabet) · IPO 2004
IPO price: $85 per share
Stock jumped 18% on day one and doubled within two months. Investors who thought the $23 billion valuation was expensive watched it grow to over $2 trillion. Investments held since the 2004 IPO have yielded returns of over 6,600%.

Meta (Facebook) · IPO 2012
IPO price: $38 per share
One of the most hyped IPOs in history — and a disaster on day one. A Nasdaq glitch delayed trading. The stock spent over a year below its $38 IPO price. Media called it a failure. Then it quietly became one of the best investments of the decade. Anyone who held from IPO is up over 1,000%.

Tesla · IPO 2010
IPO price: $17 per share
Musk's own blueprint. Listed as a cash-burning electric car company most thought would fail. Survived near-bankruptcy, multiple crises, years of volatility. Rewarded patient investors with returns of nearly 15,000%. This is the precedent SpaceX investors point to.

Nvidia · IPO 1999
IPO price: $12 per share
Listed as a graphics chip company for video games. Nobody imagined it would become the engine of an AI revolution. A £1,000 investment held through every crash and every quiet year would be worth over £1 million today — the single best-performing major IPO in history by total return.

The Asterisk Nobody Mentions
These numbers are extraordinary — and they are also deeply misleading as a guide to what happens next. For every Amazon or Google, there are dozens of IPOs that fell 50%, 70%, or to zero. Studies consistently show that the average IPO underperforms the broader market in its first year. The stories we remember are survivorship bias at its most elegant: we talk about the winners because the failures disappear quietly.

Why It Matters
What this means for UK investors — and for markets more broadly
SpaceX will list on the US Nasdaq, not the London Stock Exchange. But that does not mean UK investors are locked out. Once listed, SpaceX shares will be accessible through most UK investment platforms that offer US equity trading — the same way millions of British investors already hold Apple, Microsoft, and Amazon in their ISAs and self-invested pensions.
Reports suggest Musk is looking to allocate up to 30 percent of IPO shares directly to retail investors — at least three times the typical 5–10 percent reserved in a standard US listing. Whether that ambition translates into actual access for small investors remains to be seen.
Beyond direct access, the size of this IPO matters for markets broadly. Existing space-ecosystem stocks — satellite companies, defence contractors, infrastructure providers — have already started moving because investors are hunting for SpaceX-adjacent exposure ahead of listing. These ripple effects are the kind of thing your pension fund manager is paying close attention to, even if they never buy a single SpaceX share directly.
What Smart Observers Are Watching
The bull case, the bear case, and the question everyone is avoiding
The bull case: SpaceX holds a near-monopoly in commercial rocket launches, controls the world's most advanced satellite broadband network, and is led by someone with a track record of building companies analysts consistently underestimated. Starlink revenue is growing fast, and the long-term opportunity — dominating satellite internet globally, leading AI infrastructure — is almost without parallel.
The bear case centres on three things. First, the valuation: at roughly 110 times trailing revenue, SpaceX lists at a multiple higher than any major public technology company currently trading. Second, the losses: SpaceX reported a $2.59 billion operating loss in 2025, widening in early 2026, even as revenue grew. Third, the xAI complication: absorbing a cash-burning AI venture into the prospectus just before listing raises questions about whether SpaceX's core profits could be used to subsidise Musk's AI ambitions.
The governance question is the one most commentators avoid. Musk controls 85.1 percent of combined voting power. The prospectus states plainly: “This will limit or preclude your ability to influence corporate matters.” Buying SpaceX stock is not buying a share in a company you can influence — it is buying a financial stake in one man's vision, with no meaningful recourse if that vision changes.

The Lens Takeaway
This is the moment to understand the difference between a great company and a great investment.
SpaceX may well be the most extraordinary company to list on a public exchange in a generation. Its technology lead is real. Its revenue is growing. All of that can be true — and the stock can still disappoint investors who buy at $1.77 trillion expecting Amazon-style returns.
Amazon went public at a valuation of $438 million. It had room to become a trillion-dollar company. SpaceX starts at $1.77 trillion. For it to match Amazon's long-run return, it would need to reach roughly $32 trillion in market value — more than the current combined market cap of every company in the S&P 500.
Something to sit with: The companies that produced the greatest IPO returns — Amazon, Google, Nvidia — were not recognised as world-changers at the time. SpaceX already is. That changes the equation entirely.

On The Radar
Smaller companies generating buzz in the SpaceX orbit — not as tips, but as names worth understanding as the space economy grows.
|
| |
Space Launch · USA / New Zealand
Rocket Lab (RKLB)
The most credible smaller rival in commercial launch. Where SpaceX dominates large payloads, Rocket Lab has built a strong position in small satellite launches with its Electron rocket and is developing a larger Neutron rocket for direct competition. Already publicly listed, already generating revenue on a mission basis.
Why people are watching: A way to access the commercial space theme at a fraction of the valuation debate surrounding SpaceX itself.
|
| |
Satellite Broadband · USA
AST SpaceMobile (ASTS)
While Starlink requires a dish, AST is building satellites designed to connect directly to ordinary mobile phones — no special hardware needed. Partnerships with AT&T and Vodafone. If it works at scale, it would connect billions using the phone already in their pocket.
Why people are watching: Genuinely differentiated from Starlink. The risk is whether the technology can scale profitably against larger, better-funded rivals.
|
| |
Earth Observation · USA
Planet Labs (PL)
Operates over 200 small satellites that photograph the entire surface of the Earth every single day. That data is sold to governments, agricultural businesses, insurance companies, and financial analysts. Climate monitoring, crop tracking, shipping analysis, conflict zone observation — all now commercially available.
Why people are watching: As SpaceX makes launches cheaper, Planet Labs benefits directly. It is a data business with space infrastructure — and data businesses tend to scale when infrastructure costs fall.

A note on On The Radar: These companies are included because understanding the wider space economy is genuinely educational. None of this is a recommendation to buy, sell, or research these companies. Space stocks are among the most volatile on public markets. Always consult a qualified financial adviser.

Key Terms — Plain English
IPO (Initial Public Offering)
The moment a private company sells shares to the public for the first time and begins trading on a stock exchange. It is how companies raise large capital quickly, and how early investors convert their stake into cash.
Dual-Class Share Structure
A structure where founders hold shares with far more votes per share than public investors. It lets founders like Musk raise billions while retaining complete decision-making control. Google, Meta, and Tesla all use similar structures.
Valuation Multiple
How expensive a company is relative to what it earns or generates in revenue. High multiples reflect high growth expectations — and carry higher risk if those expectations are not met.
Survivorship Bias
The tendency to focus only on the companies that succeeded while ignoring the many that failed. We remember Amazon and Google because we cannot stop talking about them. The failures disappear quietly.
Operating Loss
When a company spends more running its business than it earns. SpaceX reported a $2.59 billion operating loss in 2025 even as revenue grew to $18.7 billion. It does not mean failure — but it does mean investors are betting on future profitability rather than present earnings.
