SpaceX Short Seller Scores Massive Own Goal

The valuation attack that aged fast

The current SpaceX debate began with a simple, punchy claim: a high-profile short seller argued that a company valued near 2 trillion dollars and trading close to 100 times revenue was wildly overstretched [1]. On its face, that kind of multiple is easy to criticize. Public-market history is not kind to businesses priced as if years of execution have already happened.

But the problem for the bearish case is timing. A revenue multiple is only as useful as the revenue base used in the calculation. The HelloBro.ai summary of the dispute highlights exactly that issue: critics of the short-seller framing argue that the 100-times figure appears to rely on stale or incomplete sales data, just as SpaceX’s latest quarter changed the scale of the business [1].

That is why the “own goal” label fits. The bearish argument wanted investors to focus on arithmetic. Fresh arithmetic is now the reason the argument looks less convincing.

The denominator changed

SpaceX reported third-quarter revenue of about 14.6 billion dollars, up 161% year over year, and net income of about 4.4 billion dollars, according to recent reporting on the company’s quarterly results [3]. Annualize that single quarter and the run rate is roughly 58.4 billion dollars. At a 2 trillion-dollar valuation, that implies about 34 times annualized third-quarter revenue, not 100 times.

That is still expensive. It is not a value stock multiple, and it does not make the risks disappear. But it is a very different argument. “Too expensive at 100 times stale revenue” and “expensive at roughly the mid-30s on annualized current revenue” are not the same thesis.

The company’s own quarterly filing reinforces the scale of the shift. SpaceX said revenue in the three months ended September 30, 2026 increased by 8.999 billion dollars, or 161.4%, from the same period a year earlier [2]. It also reported that net income for the quarter increased by 5.458 billion dollars versus the prior-year period [2]. That combination of top-line acceleration and profitability makes a simple trailing-sales critique harder to sustain.

AI compute has become the swing factor

The biggest change is not rockets. It is compute.

SpaceX’s AI unit, now framed as Super Intelligence, generated 7.56 billion dollars in third-quarter revenue, more than nine times the prior-year level, according to The Next Web’s report on the latest results [3]. The same report said the business comes largely from renting data-center computing power to outside customers, naming Anthropic, Google and Reflection AI among users cited by Reuters [3].

That matters because the short-seller thesis is not just a claim about price. It is a claim about the quality of revenue. If the new AI line is a fragile, low-margin, commodity rental business, then the bear case still has room. If compute scarcity persists and SpaceX can keep selling capacity at attractive economics, the valuation math changes quickly.

The company’s filing shows why bulls are leaning into the second interpretation. SpaceX said its SI revenue increased by 6.747 billion dollars, or 829.9%, year over year in the third quarter, driven by SI solutions and infrastructure revenue [2]. On the earnings coverage, management also said new computing capacity pays for itself in less than a year at current prices [3]. That is the kind of statement bears must disprove, not merely dismiss.

Starlink is not being replaced; it is being joined

The other flaw in the narrow valuation critique is that it treats SpaceX as if it has only one engine. AI compute is now the fastest-growing piece, but Starlink remains a major operating foundation.

Connectivity revenue, mainly Starlink, rose 69% to 5.25 billion dollars in the third quarter, and the satellite internet service ended September with 13.6 million consumer subscribers, up from 7.2 million a year earlier [3]. In SpaceX’s filing, the company said connectivity revenue rose 2.151 billion dollars, or 69.5%, compared with the year-earlier quarter, driven by consumer subscriber growth and enterprise and government business [2].

That is a useful counterweight to the idea that the current valuation is built only on speculative AI dreams. Starlink is not a concept slide. It is a large recurring-revenue connectivity business that continues to add subscribers, aircraft contracts and government usage. The filing also notes that Starlink consumer subscribers reached 13.6 million as of September 30, 2026, versus 7.2 million a year earlier [2].

The caution is that growth has a price. The Next Web reported that Starlink’s average monthly revenue per subscriber has fallen from 99 dollars in 2023 to 69 dollars as the company expands into cheaper plans and lower-income markets [3]. That is not fatal; it may be the normal trade-off of global scale. But it is a reminder that bulls should not pretend every revenue dollar is equally valuable.

Launch capacity is still the strategic hinge

The short case also has to account for the launch side, because SpaceX’s long-term valuation depends on whether Starship changes unit economics for satellites, broadband capacity and eventually orbital infrastructure.

The latest numbers show the conventional launch business is no longer the only story. Space revenue was about 1.77 billion dollars, up only modestly from 1.67 billion dollars a year earlier, according to The Next Web [3]. SpaceX’s filing similarly shows Space segment revenue increased by 101 million dollars, or 6.1%, year over year in the third quarter [2].

Yet the strategic relevance is bigger than that revenue line. The disputed bull case depends on Starship increasing payload capacity and lowering cost per unit of capacity deployed. The HelloBro.ai summary notes that a recent Starship test carrying 26 V3 Starlink satellites was cited by bulls as evidence that larger Starship deployments could accelerate network expansion [1]. The Next Web also cautioned that Starship is still not carrying paying customers and that the latest orbital test ended earlier than planned after an engine fault [3].

That is the right balance. Starship is a major optionality lever, but it is not yet a fully de-risked commercial machine. The short seller’s best remaining argument is not that SpaceX cannot grow; it is that the growth requires flawless execution across rockets, power, chips, data centers and communications markets.

Why the “own goal” matters

The short seller may still be right that investors are paying for a lot of future success. Capital expenditure is enormous: SpaceX invested 19.6 billion dollars in the quarter, with 16.4 billion dollars going into AI and data centers, and it guided for even heavier fourth-quarter spending [3]. The company’s own filing also lists 19.593 billion dollars of third-quarter capital expenditures, most of it in the SI segment [2].

But the bearish presentation appears to have picked the wrong static metric at the wrong moment. A price-to-sales critique works best when sales are stable, slow-growing or low-quality. SpaceX has just posted a quarter in which revenue more than doubled year over year, AI infrastructure became the largest revenue contributor, and Starlink kept scaling [2][3].

That does not prove the stock is cheap. It proves that the old multiple is no longer enough. To win the argument now, skeptics need to show that AI compute demand will fade, Starlink margins will compress, Starship will fail to reach useful cadence, or capital needs will overwhelm the business. Merely repeating “100 times revenue” after the revenue base has shifted is not analysis. It is a launch sequence with the coordinates left over from the previous mission.

In valuations, as in rocket science, timing matters. This time, the short-seller critique may have ignited just as SpaceX’s revenue engines lit together.
