If SpaceX Goes Public, Wall Street Will Have to Choose: Starlink or Mars?

SpaceX hasn't gone public. But let's pretend it does tomorrow, and watch what happens when the market tries to price a company that's simultaneously a boring utilities play and humanity's backup plan.

The setup is familiar: a massive IPO, retail investors get preferential allocation, institutional money floods in, the stock pops 15-20% on day one. Everyone's excited. Then quarterly earnings arrive and someone asks the question nobody wants to answer: how do you model a Mars colonization company for a 10-K?

Here's the real tension. SpaceX's actual money comes from Starlink—profitable, scaled, boring in the best way. Starlink has millions of subscribers and operates with healthy margins. Launch services are the prestige business, the one that gets Elon on podcasts. The AI division (xAI, acquired in 2024) is still experimental.

So the IPO valuation hinges entirely on which SpaceX story wins. Is this a satellite internet company that happens to land rockets? Or an existential technology bet that occasionally funds operations with broadband subscriptions? Wall Street will price in the Mars narrative—it always does—because the vision sells better than the spreadsheet. Until it doesn't.

The market will believe in the story right up until the moment institutional investors wake up and realize quarterly guidance doesn't include "establishing a human settlement" as a line item. Then the stock corrects 20-30% because that's what happens when vision meets the brutal reality of earnings per share.

If SpaceX does IPO, watch the first two days. Then watch what happens in week three.
