$75 billion to raise. A $1.75 trillion valuation. A ticker called SPCX. And a $28.5 trillion market claim that should make every founder squint.
Twenty-four years after Elon Musk founded it, SpaceX has finally shown its cards. The company made its IPO filing public on Wednesday after markets closed, and the document is a business nerd’s dream: equal parts spreadsheet, sci-fi novel, and power grab.
Here’s the headline. This is not “one of” the biggest IPOs. It’s on track to be the biggest. SpaceX is expected to raise around $75 billion at a reported $1.75 trillion valuation. That would instantly rank it among the most valuable public companies alive. Nvidia leads the pack at a $5.4 trillion market cap, so SpaceX would be playing in rarefied air.
It’s heading to the Nasdaq under the ticker “SPCX.” Subtle? No. Fitting? Absolutely.
The money story is messier than the press photos
Lean in here, because this is the part the rocket footage hides. SpaceX is not a tidy profit machine. It lost roughly $4.9 billion in 2025 on more than $18 billion in revenue. Zoom out to the full timeline and the company has burned over $37 billion since inception.
That’s a wild number. It’s also exactly how moonshots get built. You don’t get reusable rockets and global satellite internet by breaking even every quarter.
And the revenue engine right now isn’t rockets at all. It’s Starlink, the satellite internet business, which brought in more than half of SpaceX’s revenue last year, around $11 billion. Quietly, SpaceX became a telecom company that happens to own the best rockets on Earth.
The AI bet nobody fully expected
Plot twist. Musk merged xAI, his artificial intelligence company and the home of the Grok chatbot, into SpaceX. The filing reveals just how heavy that bet is: roughly 60% of SpaceX’s 2025 capital spending, around $20 billion, went to the AI division.
The results so far? Underwhelming. The AI unit lost billions last year and grew revenue only about 22%. That sounds respectable until you remember frontier AI labs are reportedly growing far faster. For now, SpaceX’s AI arm is the slow runner in a very fast race.
Then comes the eyebrow-raiser. SpaceX claims it has “identified the largest actionable total addressable market in human history,” worth $28.5 trillion, with $22.7 trillion of that pinned to enterprise AI.
Real talk: a TAM that big isn’t a market estimate, it’s a vision statement. Sharp founders read a number like that as ambition, not arithmetic. It tells you where Musk wants to go. It says almost nothing about what SpaceX will actually earn.
It all rests on one rocket
Strip away the conglomerate sprawl and SpaceX’s future hangs on Starship, the fully reusable heavy-lift rocket that has logged explosions and redesigns for years. The 12th Starship launch could come as early as this week, and the stakes are enormous.
SpaceX told regulators it expects Starship to start delivering payloads to orbit in the second half of 2026. That leaves almost no margin for error. The R&D bill is brutal: $3 billion on Starship in 2025, plus another $930 million in just the first quarter of 2026.
Why keep spending? Because SpaceX believes Starship can cut the cost of reaching orbit by 99% or more versus the historical average. If that math holds, every space business on the planet gets rewritten.
The sci-fi section of the filing
Tucked inside the document is a wishlist that reads like a Saturday morning cartoon, and honestly that’s part of the charm. SpaceX lists “future markets” including:
- Point-to-point Earth travel, flying passengers city to city in a fraction of current flight times
- Space tourism, building on its past private astronaut missions
- In-space manufacturing, making pharmaceuticals and materials in microgravity
- Asteroid mining, with almost zero detail on how
None of it is near-term. SpaceX labels these “future markets,” which is filing-speak for “ask us later.” But putting asteroid mining in an official SEC document is a flex few companies could pull off.
Make no mistake, this is Elon’s company
The filing erases any doubt about who runs the show. After the IPO, Musk will be CEO, CTO, and Chairman of the board. All three.
He owns 93.6% of SpaceX’s Class B stock, which carries 10 votes per share, handing him 85.1% of voting power today. After the IPO that drops, but stays above 50%, which conveniently lets SpaceX skip certain rules about independent directors.
His new pay package is peak Musk. He could earn up to 1 billion Class B shares, but only if he hits targets like a $7.5 trillion valuation and “a permanent human colony on Mars with at least one million inhabitants.” Clear a few more goals on space-based data centers and he earns even more.
The Business Model Angle
For anyone building a company, SpaceX’s filing is more than a space story. It’s a playbook:
Cross-subsidization is a superpower. Starlink’s $11 billion pays the bills so Starship and AI can chase the dream. The lesson: a boring, profitable core buys you the right to gamble. Build the cash cow first, then fund the moonshot. Founders who chase the moonshot with no cash engine just run out of runway. (Worth studying how the full SpaceX business model fits together if you want the deeper breakdown.)
Capex is the new moat. SpaceX spent $20 billion on AI and billions more on rockets in a single year. That scale of physical investment is something a competitor cannot copy with a clever app. In an AI era, the defensible businesses increasingly own expensive, hard-to-replicate infrastructure, not just code.
Vision is a product you sell to investors. Asteroid mining and Mars colonies aren’t revenue lines, they’re narrative. SpaceX is asking the public to value it at $1.75 trillion partly on markets that don’t exist yet, and investors are lining up. Story-driven valuation is real. Just know the difference between selling a vision and believing your own TAM slide.
The “future markets” label is a strategy tool. Notice how SpaceX gets credit for point-to-point travel and space tourism without those ideas facing the same scrutiny as its core business. Smart positioning: signal optionality and upside, while keeping the speculative stuff clearly fenced off from what investors are actually underwriting.
The Takeaway
SpaceX’s IPO is a masterclass in one specific strategy: build a wildly profitable core, then use it to fund an absurdly ambitious frontier. Starlink pays. Starship and AI dream. Investors bet on both at once.
The risk is just as clear. This is a company losing nearly $5 billion a year, leaning on one unproven rocket, asking for a $1.75 trillion price tag partly on markets that don’t exist. That’s not a bug in the pitch. That is the pitch.
When SPCX hits the Nasdaq later this year, you’ll watch one of the boldest wagers in business history go live in real time. Bring popcorn.
