The Number on the Term Sheet
SpaceX is preparing what analysts expect to be the largest initial public offering in market history, with shares priced at roughly $135. That figure implies a valuation that would place SpaceX among the most valuable companies ever to go public — before it has reported a single quarter of earnings as a public company.
Wall Street, to its credit, is not pretending this is straightforward.
What the Bulls Are Buying
The optimistic case for SpaceX at this price rests on three pillars: Starlink, Starship, and the structural moat of vertical integration in launch.
Starlink, the satellite internet subsidiary, is the most legible of the three. It has paying subscribers, recurring revenue, and a defensible position in low-Earth orbit broadband — particularly in underserved and rural markets where terrestrial infrastructure is thin. Analysts who are constructive on the IPO tend to anchor their models here, treating Starlink as a high-growth SaaS business attached to a rocket company at no extra charge.
Starship, the heavy-lift vehicle still in active development, is harder to model. Its commercial potential — deep-space cargo, point-to-point Earth transit, eventual crewed missions — is genuinely large. The timeline to revenue is genuinely uncertain. Investors pricing that optionality at $135 per share are making a bet that requires Starship to work, to work on schedule, and to find customers willing to pay for capabilities that do not yet exist at commercial scale.
The third pillar, launch dominance, is the most defensible today. SpaceX's Falcon 9 has a reliability record and cost structure that competitors have not matched. Government contracts — NASA, the Department of Defense — provide a revenue floor. That floor is real. Whether it justifies the ceiling implied by the IPO price is the question analysts are arguing about.
What the Bears Are Counting
Skeptics are not disputing that SpaceX is a remarkable company. They are disputing the math required to make $135 work.
At the implied valuation, investors are paying a multiple that assumes Starlink scales to a subscriber base and average revenue per user that would make it one of the largest telecom businesses in the world. They are also assuming Starship transitions from a development program to a commercial product without the delays that have historically characterized aerospace programs of comparable ambition.
There is also the governance question that polite analysts mention in footnotes. Elon Musk's involvement in SpaceX is not separable from its valuation — his relationships with government customers, his public profile, and his decision-making authority are all priced in. So is the risk that his attention, or his reputation, shifts.
What the Cap Table Already Knows
SpaceX has raised capital across multiple private rounds at escalating valuations. Late-stage private investors are sitting on paper gains that only crystallize if the public market accepts the price. The IPO is, among other things, a liquidity event for people who have been waiting a long time.
That dynamic does not make the offering bad. It does mean that the $135 price was not set in a vacuum — it was set in a context where a great many sophisticated investors needed a number that worked for them. Public market buyers should understand they are arriving after several chapters have already been written.
The Honest Summary
SpaceX may well be worth $135 a share. The company has real revenue, real technology, and a competitive position that is genuinely difficult to replicate. What it does not have, at this price, is much margin for the assumptions to be wrong.
