Today, for the first time, you can own a piece of SpaceX. The rocket company — now also the Starlink company, and as of February the xAI company too — lists on the Nasdaq today at $135 per share, valuing it around $1.75 trillion. That makes this the largest IPO in stock market history, and SpaceX instantly one of the most valuable companies on earth — bigger than Tesla. But here's what the hype coverage won't tell you: the company's own filings show that the rockets lose money, the AI division lost over $6 billion last year, and the entire profit engine is something quieter — a satellite internet subscription business. If you're thinking about this stock, you need to know what you're actually buying.
Here's what they actually said.
The Basics: What's Happening Today
- The event: SpaceX begins trading on the Nasdaq under ticker SPCX
- The price: $135 per share, set last night
- The valuation: roughly $1.75 trillion — the biggest IPO ever, raising around $75 billion
- 2025 revenue: $18.67 billion, with an operating loss of $2.6 billion
- 2025 adjusted EBITDA: $6.58 billion
- The float: only ~3–4% of the company is actually being sold
- First earnings report: November 2026
An IPO — initial public offering — is the moment a private company sells shares to the public for the first time. Until now, only insiders, employees, and select funds could own SpaceX; from today, anyone with a brokerage app can. The S-1 is the giant disclosure document a company must file before listing — the first time SpaceX has ever been forced to show the world its real numbers. Everything in this article comes from that filing. That's also why this moment matters beyond the hype: the world's most mythologised private company just opened its books.
What You're Actually Buying: Three Very Different Businesses
The filings reveal SpaceX is really three companies stapled together, with wildly different economics.
1. Starlink (the moneymaker). The satellite internet service generated $11.4 billion of revenue in 2025 with $4.4 billion of operating profit — a 63% adjusted EBITDA margin. Subscribers more than doubled in a year, from 4.5 million to over 10.3 million. This is the only part of SpaceX that makes money, and it makes a lot of it.
2. Launch (the famous part). The rockets — Falcon, Starship, the things that land themselves. Revolutionary engineering, dominant market share... and a money loser, with around $3 billion poured into Starship development in 2025 alone, plus another $930 million in the first quarter of 2026.
3. xAI (the wildcard). In February 2026, SpaceX absorbed Elon Musk's AI company — which itself owns X, formerly Twitter — in an all-stock deal valued around $250 billion. xAI posted an operating loss of roughly $6.4 billion in 2025. The combined company is rebranding as SpaceXAI.
Strip away the rockets and the headline valuation, and the profit story is a subscription internet provider. Starlink works like Netflix or Spotify economics — recurring monthly payments, and once the satellites are up, each new subscriber is nearly pure margin. The rockets are, financially speaking, the world's most spectacular cost centre that happens to also launch the satellites. And the AI division is a multi-billion-euro annual bet that hasn't paid off yet. You're buying all three with one ticker. There's no way to own just the profitable part.

At a $1.75 trillion valuation against $18.7 billion of 2025 revenue, SpaceX is priced at roughly 94 times sales — while losing money at the operating level.
For comparison: Nvidia, the most celebrated stock of the AI era, trades around 25–30 times sales with enormous profits. Tesla, the market's most famous "priced for the future" stock, trades far cheaper relative to its revenue. SpaceX's price assumes not just success, but decades of near-flawless, compounding success — Starlink conquering global internet, Starship opening entirely new markets, xAI winning in AI.
"Price-to-sales" compares what investors pay for a company against the revenue it generates. There's no magic right number, but 94x means you're paying for the company SpaceX might become in the 2030s, not the company the filings describe today. That's not automatically wrong — early Amazon looked insane by these measures too. But it means the margin for disappointment is essentially zero, and any stumble has a very long way to fall.
Why the First Days Will Be Wild
Two structural quirks make the early trading unpredictable. First, scarcity by design: only about 3–4% of the company is being sold, so a flood of demand is chasing a trickle of shares — a recipe for sharp price swings in both directions. Second, forced buying: index provider MSCI announced SPCX qualifies for fast-track inclusion in its major indices from June 13, meaning index funds tracking those benchmarks must buy shares almost immediately, regardless of price.
History adds a caution: heavily hyped IPOs commonly trade far above sensible value in week one, then fall back over the following months once the excitement meets the financials.
The "float" is the portion of shares actually available to trade. A tiny float means the day-one price reflects supply and demand mechanics more than the company's worth — like judging a city's house prices when only four houses are for sale. And index inclusion creates buyers who must buy. Both forces push the price around for reasons that have nothing to do with rockets, satellites, or AI. The first genuinely informative moment for this stock is the first earnings report in November.
What's Coming Next
The first real test arrives in November 2026: SpaceX's first quarterly earnings report as a public company, with a full quarter of SEC-audited numbers and — for the first time ever — Elon Musk answering analyst questions about SpaceX on an earnings call. Until then, watch Starlink subscriber growth (the entire profit story), Starship's progress toward revenue-generating flights, and how much cash xAI consumes.
We'll break that first report down in plain English the day it lands.
Public life changes a company. SpaceX could previously develop rockets and burn cash in private, on its own timeline. From today, it reports to millions of shareholders every ninety days, and every explosion, delay, and missed target happens in front of a live stock price. The most interesting question of this IPO isn't day one — it's whether the company that moved fast in private can thrive under quarterly scrutiny.
The Bottom Line
↑ Why This Matters (Bull Case)
You're buying the most dominant position in two of the most important industries of the century. Starlink is a genuine money machine — $11.4 billion of revenue at 63% margins, subscribers doubling yearly — with a satellite internet market still in its infancy. The launch business holds near-monopoly market share in commercial spaceflight, and Starship could reduce the cost of reaching orbit by an order of magnitude, unlocking markets that don't exist yet. Add xAI's upside, index-fund demand, and the sheer gravitational pull of the Musk story, and this is the defining growth stock of its generation — the kind people regret not buying for decades.
↓ Why This Might Worry You (Bear Case)
The filings, not the critics, say it: an operating loss of $2.6 billion in 2025, an AI division losing $6.4 billion a year, and a price of ~94 times revenue that assumes perfection forever. Key-man risk is extreme — this valuation is inseparable from one famously unpredictable individual, who now also runs your AI lab and your social network inside the same stock. The tiny float and index-fund mechanics mean early prices may be meaningless, and hyped IPOs have a long history of painful first-year retraces. You can love SpaceX — the rockets, the mission, all of it — and still conclude the stock at this price is a different proposition entirely.
The question is the oldest one in investing, at the largest scale ever attempted: is a great company automatically a great investment — at any price?
