SpaceX Valuation Disparity Shapes Retail Decisions

NYU finance professor Aswath Damodaran pegged SpaceX at $1.3 trillion after reviewing the IPO prospectus – $500 billion below the $1.8 trillion valuation the company is seeking, a spread that carries direct implications for retail investors weighing the debut.

With SpaceX’s IPO representing what many observers call the largest public offering in history, the gap between Damodaran’s intrinsic-value estimate and the company’s own target price amounts to roughly 28 cents on every dollar investors would pay at the proposed valuation ¹.

The Valuation Gap in Context

A $1.8 trillion price tag would place SpaceX at roughly 100 times last year’s adjusted operating profit – a multiple that dwarfs even the loftiest large-cap tech peers trading on public markets today ¹. Damodaran’s $1.3 trillion estimate, itself a revision upward from a pre-prospectus figure of $1.2 trillion, translates to approximately $100 per share and still implies the company is pricing in decades of near-flawless execution across three distinct businesses.

The underlying financials give pause: SpaceX generated under $7 billion in EBITDA last year, even on an adjusted basis that strips out interest, taxes, depreciation and amortisation ¹. That means investors paying the full $1.8 trillion ask are effectively pricing in a business that must grow many multiples of its current size before conventional return thresholds are met.

Segment-by-Segment Margin Forecasts

Damodaran’s revised model treats SpaceX as three separate businesses, each with materially different margin trajectories. The launch and space-infrastructure arm posted a 67% gross margin – the strongest unit economics of the three – and Damodaran lifted his long-run margin assumption for that segment to 45% from an earlier 40% ¹.

Starlink, the satellite internet connectivity division, carried 48% gross margins in the most recent period, and Damodaran projects those improve to 60% at scale because the capital-intensive satellite constellation is already largely in orbit ¹. The AI segment is the outlier: margins were not only the lowest of the three, they were actively contracting amid intensifying competition, prompting Damodaran to slash his long-run AI margin assumption to 25% from an earlier forecast of 45%.

Total Addressable Market: A Point of Contention

SpaceX’s prospectus identifies a $26 trillion total addressable market for its AI business – a figure Damodaran dismissed outright, applying the same skepticism he used when analysing Uber Technologies and Airbnb IPO filings ¹. His own TAM estimate for AI products and services landed between $3 trillion and $4 trillion, roughly one-eighth the company’s claim.

The professor also pushed back on critics who reject the deal on traditional value-investing grounds.

“SpaceX is a company with small revenues and large losses, and paying a hundred times revenues for it seems foolhardy. I have no quarrels with this point of view, which animates old-time value investing, but this perspective comes with a cost in terms of investment choices,” Damodaran said, adding that such investors risk ending up with portfolios of mature and declining businesses.

Risk/Reward and the Short-Squeeze Warning

Damodaran drew on two high-profile IPO precedents to frame the entry-price risk: Facebook traded at roughly half its offering price within months of listing, and Uber shed more than 50% of its market capitalisation in the year after going public – both eventually recovering to trade well above their IPO levels ¹. The analogy suggests a patient buyer could find a better entry point if the stock follows a similar post-IPO trajectory.

For those tempted to bet against the offering, Damodaran issued a clear caution, citing the “shifting and often unpredictable forces of mood and momentum” as his reason for refusing to short SpaceX shares ¹. The narrative premium embedded in Elon Musk-affiliated companies – echoing the pattern seen at Tesla – means sentiment can override fundamentals for extended periods, making short positions structurally hazardous.

Outlook

Damodaran said he plans to remain on the sidelines at the current proposed valuation but would reconsider if the stock declines sufficiently after listing to close the gap between market price and his $1.3 trillion intrinsic estimate ¹. That implies a potential entry threshold somewhere below $100 per share on his model – a data point deal-focused investors may want to bookmark ahead of the IPO date.
