The market is pricing SpaceX at $1.75 trillion. That figure sits near the top of the S&P 500, alongside companies that generate hundreds of billions in revenue and run consistent profits. SpaceX generated $18.7 billion in revenue in 2025 - a solid number, but one that is a fraction of what the valuation implies. The company also lost $4.9 billion that same year. Then in the first quarter of 2026 alone, it lost another $4.3 billion on $4.7 billion in revenue. The accumulated deficit - the running total of all losses the company has ever posted - sits at $41.3 billion.
I have spent my career looking for cash-flow discounts - companies the market underprices because it has overlooked how much real money the business generates. SpaceX's S-1 filing, which became public last week ahead of a Nasdaq listing expected in June, is the opposite of that. It is a disclosure document that should force investors to ask a simple question: at what point does growth in revenue offset a $41 billion hole in the ground?
The revenue story is the one part that checks out. SpaceX grew revenue 33% year-over-year in 2025 and 15% in the first quarter of 2026. Starlink - the satellite internet division - is genuinely the standout. It produced $11.4 billion in revenue, $7.2 billion in segment adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization, a rough proxy for cash earnings before capital spending), and 63% EBITDA margins. That is a high-margin, scalable business. If SpaceX were only Starlink, the conversation would be very different.
But SpaceX is not only Starlink. The Space segment - launch services, government contracts, satellite manufacturing - posted a $351 million adjusted EBITDA loss in Q1 2026, reversing from a $1.15 billion profit on a full-year basis in 2024. The company is also now an AI company, which is a detail the trillion-dollar narrative tends to gloss over. SpaceX acquired xAI in February 2026, and the capital expenditure implications are staggering. In Q1 2026, of $10.1 billion in total capex, $7.7 billion went to AI infrastructure. Over the full period covered in the S-1, 61% of $20.7 billion in total capex was directed at AI. xAI lost $4.3 billion in the first quarter alone.
Let me be clear about what this means. The company is not growing its way to profitability while building the future. It is burning $4.3 billion a quarter to fund an AI bet that has already lost more money in three months than Starlink generated in segment EBITDA in the same period. The S-1 shows operating cash flow of $1.0 billion in Q1 2026, but that is before you account for the capital spending required to keep the machines running. Operating cash flow is positive because the company is collecting on government contracts and Starlink subscriptions, not because the overall business has found a path to sustainable free cash flow.
Now let's talk about the structure, because the IPO mechanics are as revealing as the financials.
SpaceX is using a dual-class share structure. Class B shares carry 10 votes each, while Class A shares carry one. Musk will own the majority of Class B shares, meaning he retains absolute voting control even after the IPO dilutes his economic ownership. The company will qualify as a "controlled company" under exchange rules, which means it is exempt from certain corporate governance requirements that normally protect public shareholders. That matters. It means Musk decides, not shareholders.
Then there is the lockup - the period after an IPO during which insiders are normally barred from selling their shares. Standard practice is 180 days. SpaceX is doing something very different. The company has structured five time-based tranches that unlock 7% of eligible insider shares at 70, 90, 105, 120, and 135 days after listing. Within roughly four and a half months, 35% of insider shares will be eligible for sale. After the company reports its first post-IPO earnings, an additional 28% unlocks. That means 63% of insider shares can hit the market within roughly six months.
I would call this an aggressive exit structure. The conventional lockup exists because investors need to know insiders believe in the business they are asking the public to fund. When you allow insiders to start selling after 70 days - a little over two months - you are signaling that the insiders themselves don't need to be married to the public valuation they are creating. This is not alignment. It is liquidity.
From a valuation perspective, the $1.75 trillion target is roughly 93 times 2025 revenue. Even using the more generous segment adjusted EBITDA figure of $7.2 billion from Starlink alone, the implied multiple on the entire company is nearly 243 times. There is no oil company, no pipeline, no cash-flow business on earth that commands anything close to that. And SpaceX is not a cash-flow business yet - it is a capital-consumption engine wrapped in a revenue-growth story.
While it's true that SpaceX is raising up to $75 billion - a record amount - to fund this expansion, that doesn't make the valuation defensible. It makes the math clearer: the company needs the money because it is burning through cash faster than it generates it, and it needs the market to fund the AI bet that is already hemorrhaging billions. The IPO is not a reward for profitability. It is a refueling stop.
All things considered, SpaceX is a fascinating company with real revenue growth and a genuinely profitable satellite division. But fascination is not a margin of safety. A $1.75 trillion valuation on a company with $41.3 billion in accumulated losses, a quarter-by-quarter net loss trajectory, a massive and unproven AI capital commitment, and an insider selling structure that unlocks in 70 days is not a value opportunity. It is a narrative play priced at the top of a narrative.
There's better out there. Companies that trade below their cash-flow generation, where the math works in your favor rather than against it, where you don't need to hope that a $20 billion capex program produces returns that magically justify a trillion-dollar tag. If you're looking for a place to be patient and let compounding work, SpaceX's IPO is not it. I would rate this a pass.
