The SpaceX IPO: The Biggest Market Debut in History
The most anticipated IPO in history is here. But is the hype worth the risk?
The rumors are over.
SpaceX is filing its IPO prospectus with the SEC, possibly this week, targeting a June 2026 listing at a $1.75 trillion valuation.
Let that number sink in for a second.
Google went public in 2004 at a $23 billion valuation. Facebook debuted in 2012 at $81 billion. Uber (the most hyped ride-share IPO of all time) came in at $75 billion.
SpaceX would dwarf every single one of them on day one.
This is not a normal IPO. And it deserves a deeper look.
What Even Is an IPO, And Why You Should Be Careful
An IPO is the moment a private company opens its doors to public investors for the first time. Founders, early employees, and venture backers, who’ve been holding illiquid stakes for years, finally get liquidity.
Here’s what most retail investors miss: the IPO is designed to benefit the sellers, not the buyers.
Investment banks price the offering as high as the market will bear (no pun intended). The roadshow is a marketing campaign. By the time the stock hits your brokerage account, insiders have already locked in their gains.
The data is pretty consistent here: IPOs underperform the broader market in the first 3-5 years after going public, on average. The exceptions include Amazon, Google, and Visa, which rewarded investors because the business was exceptional. The IPO excitement was irrelevant.
How SpaceX Compares to the Biggest IPOs in History
Here’s the IPO valuation leaderboard and where SpaceX would land:
SpaceX (2026): $1.75 trillion
Saudi Aramco (2019): $1.7 trillion
Alibaba (2014): $169 billion
Uber (2019): $75 billion
Facebook / Meta (2012): $81 billion
Google (2004): $23 billion
Tesla (2010): $1.7 billion
SpaceX would not only top the list but also have a valuation that exceeds the combined value of all other U.S. tech IPOs.
And here’s the cautionary tale hiding in that list: the most hyped IPOs often disappoint in the short term.
Facebook dropped nearly 50% in its first few months before eventually becoming one of the greatest investments in history for those patient enough to wait
Uber fell 8% on day one and kept sliding for over a year
Google had to cut its IPO price twice before going public, then quietly became a 6,500% compounder for long-term holders
Tesla IPO’d at $1.7 billion in 2010 and became a $1 trillion company, but only after years of near-bankruptcy, short-seller wars, and extreme volatility
The lesson? Great companies can still be terrible short-term IPO investments.
So, What Are You Actually Buying With SpaceX?
Most people think of SpaceX as “Elon’s rocket company.” However, that’s like calling Amazon “Jeff’s bookstore.”
After its February 2026 merger with xAI, here’s what the SpaceX entity actually includes:
SpaceX Launch Business: The world’s dominant commercial rocket provider, completing over 160 launches a year, more than half of all global orbital launches.
Starlink: The crown jewel. A global satellite internet business with 9.2 million subscribers as of late 2025, doubling its user base in 15 months. Revenue crossed $10 billion last year. High-margin, subscription-based, global reach. This is what justifies the trillion-dollar valuation.
xAI (Grok + AI Infrastructure): Musk’s AI company is now a fully owned subsidiary of SpaceX, featuring the Grok chatbot and a plan for space-based AI data centers. It is currently investing heavily to scale up, which poses a significant risk ahead of the IPO.
X (formerly Twitter): Indirectly included via the xAI acquisition. Still struggling financially, but brings a massive global user base.
Terafab: A joint Tesla-SpaceX chip manufacturing facility, just announced in Austin, Texas. One factory for Tesla’s AI and robotics needs; one for SpaceX’s orbital data centers. The first tangible sign of what a combined Musk empire could look like.
When you buy SpaceX stock, you’re buying a telecom company, an AI startup, a defense contractor, a social media platform, and a space exploration company, all under one cap table.
How SpaceX Actually Makes Money - And Is It Profitable?
This is where the story gets genuinely interesting.
SpaceX has two real revenue engines right now:
Starlink (~67% of revenue): A subscription-based satellite internet. Residential plans run ~$85- $120/month; maritime and aviation contracts go for far more. With 9.2 million subscribers across 150+ countries, Morningstar estimates Starlink generated roughly $10.6 billion in revenue in 2025 at a 54% EBITDA margin. That’s not a startup metric. That’s a mature, high-margin telecom business.
Launch Services (~33% of revenue): Falcon 9 and Falcon Heavy commercial launches at roughly $62-125 million per mission, plus NASA contracts, Pentagon deals, and crewed missions. The reusable rocket program has cut launch costs by an estimated 65%, giving SpaceX a cost advantage no competitor can currently match. In 2024, only 6% of Falcon 9 flights used new boosters. The rest were reflown hardware.
The profitability question: Yes, SpaceX is profitable. The company has reported being cash-flow positive for several years, conducting regular share buybacks. Morningstar estimates $7.5 billion in EBITDA for 2025 on roughly $16 billion in total revenue. For context, that’s a ~47% EBITDA margin whic his better than most software companies.
The catch: xAI is burning cash aggressively, and Starship development is enormously expensive. Both are now on SpaceX’s balance sheet. The core SpaceX + Starlink business is healthy. The question going into the IPO is how much of the $1.75 trillion valuation you’re paying for today’s profits versus tomorrow’s moonshots.
The Tesla-SpaceX Merger: Real or Rumor?
Bloomberg, Reuters, and TechCrunch have all reported that SpaceX is actively exploring merger scenarios with Tesla and/or xAI (which is already merging with SpaceX).
Two Nevada “merger sub” entities were quietly filed in January 2026, listing SpaceX’s CFO as an officer. That’s not nothing.
Wedbush analyst Dan Ives (one of the more credible voices covering Musk’s empire) has publicly predicted that Tesla and SpaceX will fully merge by 2027, calling Terafab the first step toward full integration.
The strategic logic is actually compelling:
Tesla’s energy storage could power SpaceX’s solar-driven orbital data centers
Starlink connectivity could enhance Tesla’s Robotaxi and Full Self-Driving network
Optimus robots (Tesla) assembling Starship components (SpaceX) - Musk has literally said this out loud
The problem? Betting markets currently put only 15% odds on a Tesla-SpaceX merger and about 48% on the SpaceX-xAI combination already in progress. A full Tesla deal would invite serious antitrust scrutiny; a combined entity of $2.6 trillion spanning EVs, energy, space, telecom, and AI would be unlike anything regulators have seen.
Bottom line: A merger is possible. Maybe even likely eventually. But it’s not priced in yet, and the uncertainty it creates is one more reason to approach this IPO with eyes wide open.
The Bull Case
Let’s be fair to the optimists.
Musk has a track record that’s genuinely hard to dismiss. Tesla went from near-bankruptcy in 2018 to one of the most valuable automakers on Earth. SpaceX went from a punchline to owning half the global launch market. Starlink went from science fiction to 9 million paying subscribers.
Musk not only creates companies but also develops ecosystems, often making the impossible seem obvious in retrospect.
If Starlink reaches 50+ million subscribers, if space-based AI infrastructure becomes reality, if Starship delivers - the growth runway here is unlike anything else in the public markets.
This is the Peter Lynch argument. Lynch invested in companies doing new things he could see and understand. SpaceX’s story, for all its complexity, is real.
The Bear Case
Now the Buffett lens.
Buffett avoids businesses he can’t value clearly, businesses burning cash to scale, and businesses run by CEOs who introduce unpredictability.
Valuation. At roughly 60-70x projected 2026 revenue, SpaceX is priced for perfection and then some. Buffett has never paid 60x revenue for anything.
The xAI problem. xAI is reportedly hemorrhaging money scaling AI compute. That red ink now sits on SpaceX’s balance sheet going into the IPO.
Musk himself. SEC quiet period rules exist for a reason. Musk has historically not been quiet. As Axios noted this week: “Today’s Musk may struggle to comport with rules about what company insiders can and can’t say once the IPO process begins.”
Governance. Musk owns a significantly larger stake in SpaceX than Tesla. Every dollar SpaceX raises at an inflated valuation benefits him disproportionately. Munger’s question always applies: “Show me the incentive and I’ll show you the outcome.”
My Take: I’m Actually Considering This One
Here’s my general rule: I almost never invest in an IPO during the first 6-12 months. IPOs are volatile, overpriced at launch, and driven by hype rather than fundamentals. Waiting for the dust to settle, for earnings reports, lockup expirations, and media excitement to fade, almost always produces a better entry point.
And yet.
SpaceX is making me reconsider that rule for the first time in a while.
Not because the IPO is priced fairly. Because I don’t know that it is. Not because the short-term will be smooth, as it likely won’t be. But because the window to get in on Musk’s most powerful asset may not come again. SpaceX has been private for 24 years. This isn’t a startup going public. It’s a proven, cash-flow-positive machine with a global telecom business at its core and an AI company bolted on top. All going public in a single shot.
Facebook cratered after its IPO, then 10x’d. Google was forced to cut its price before going public, then 65x’d. Tesla was a meme before it was a trillion-dollar company.
I’m still working through the risk. The valuation is uncomfortable. The xAI losses are real. The merger uncertainty is real. But I’m watching this one very closely, and I may just break my own rule.
I’ll keep you posted.
