On 12 June 2026, SpaceX did something Elon Musk spent years insisting it never would: it went public. And it didn’t go public quietly. It became the biggest IPO in stock market history, raising around $75 billion and instantly turning into one of the most valuable listed companies on earth.
If “IPO” makes your eyes glaze over, stick with me. This is one of the clearest real-world examples of how public markets work, and it’s worth understanding even if you’ll never buy a single share.
What is an IPO, in plain English?
IPO stands for Initial Public Offering. It’s the moment a private company sells shares of itself to the public for the first time, listing on a stock exchange so anyone with a brokerage account can buy in.
Before an IPO, a company is private: ownership is limited to founders, employees, and a small circle of investors. After an IPO, it’s public: ownership is split into shares that trade openly, and the company has to publish its financials for the world to see.
Companies do this for two main reasons: to raise a large pile of money, and to let early investors and employees finally cash out shares they’ve been holding for years.
What actually happened with the SpaceX IPO?
Here are the facts, stripped of hype:
- SpaceX priced its shares at $135 each the evening of 11 June 2026.
- It sold roughly 555 million shares, raising about $75 billion.
- That smashed the previous record, Saudi Aramco’s $29 billion listing in 2019, making it the largest IPO ever.
- Shares began trading on the Nasdaq on 12 June under the ticker SPCX.
- The stock jumped 19% on day one, closing near $161 and pushing the company’s value above $2 trillion.
For context, that day-one valuation put SpaceX among the half-dozen most valuable public companies in the United States, alongside the likes of Apple and Nvidia.
Why did SpaceX go public after saying it wouldn’t?
For years Musk argued SpaceX didn’t need public money and that going public would create distractions. So why now?
The short answer is appetite and ambition. Investor demand for anything tied to space and AI is enormous right now, which means SpaceX could raise a historic sum at a historic price. And it has expensive plans to fund, including building data centres in space and scaling up its satellite network. When the market is willing to hand you $75 billion, the maths changes.
What is SpaceX actually worth, and why?
A trillion-dollar-plus valuation for a rocket company sounds wild until you look under the hood. The real engine isn’t rockets, it’s Starlink, the satellite internet business, which crossed 10 million subscribers in early 2026 and is adding hundreds of thousands more every month. That recurring subscription revenue is exactly the kind of predictable income investors pay a premium for.
SpaceX also folded in Musk’s AI company, xAI, earlier in the year, bundling in its Grok chatbot and a massive supercomputer. So when you buy SPCX, you’re really buying a bet on three things at once: launches, satellite internet, and AI.
What does this mean for everyday investors?
If you wanted shares at the $135 IPO price, you needed an allocation through a broker ahead of time, and demand massively outstripped supply. Most regular investors who want in now have to buy on the open market, where the price is already well above where it started.
A word of caution, and this is a theme we’ll keep coming back to: a record-breaking debut is exciting, but history is full of hyped IPOs that lost a big chunk of their value within a few years. Excitement is not the same as a sure thing.
Why should a fintech audience care?
Because this is public markets and financial plumbing in action. An IPO touches almost everything The Fintech Classroom is about: how money flows, who gets access, and how technology reshapes finance. A huge share of the SPCX buying happened through fintech-era apps, the same brokerages and platforms that put investing in everyone’s pocket. The SpaceX listing is a reminder that the rails moving money into markets are themselves a fintech story.
