SpaceX's $1.75 trillion IPO and where the overflow goes

The problem is that SpaceX itself is already priced for near-perfection. At $1.75 trillion, you're not buying a hidden gem. You're buying the consensus view of what commercial spaceflight becomes over the next 20 years, at a price that leaves very little room for the story to surprise you.

So where does the overflow capital go?

Rocket Lab USA (NASDAQ:RKLB) is the answer most institutions will land on first, and for good reason. It's the only other company on earth with an operational orbital rocket flying today. Its Electron launch vehicle has now completed over 60 flights. The bigger Neutron rocket, designed to compete with SpaceX's Falcon 9, is on track for a first launch attempt in 2026. The company also runs a profitable and growing space systems business that manufactures spacecraft components and whole satellites.

The valuation gap between the two is extraordinary. SpaceX at $1.75 trillion versus Rocket Lab at roughly $15 billion. That's not a like-for-like comparison (Starlink alone likely accounts for the majority of SpaceX's value, and Rocket Lab doesn't have a Starlink equivalent). But Rocket Lab has built something SpaceX took years to prove: operational cadence. Reliable launch is genuinely hard. Most competitors have failed to get there at all.

The second-order move here is what happens to Rocket Lab's contract pipeline now that SpaceX is a public company with a disclosed balance sheet and a fiduciary duty to maximize shareholder returns. SpaceX will increasingly price Falcon 9 launches at market rates rather than as a strategic loss-leader. That creates real room for a competitor offering a credible alternative. Rocket Lab is currently the only one.

AST SpaceMobile (NASDAQ:ASTS) is a different angle. It's a satellite-to-phone broadband network that uses SpaceX rockets to get its satellites into orbit. The SpaceX IPO validates the space-based connectivity thesis ASTS is built on, and a richly valued, publicly traded Starlink creates a reference price for what that business model is worth at scale. ASTS is years behind Starlink in deployment, but it holds a specific advantage: its satellites connect to ordinary unmodified phones. No Starlink dish required. If that works at commercial scale, the addressable market is every mobile phone user on earth.

Intuitive Machines (NASDAQ:LUNR) is the third name in this bracket and the most speculative. It flies lunar landers on SpaceX rockets and holds NASA contracts for lunar surface delivery. It is, in the most literal sense, a direct beneficiary of wherever SpaceX takes the lunar economy. That also makes it the most exposed if NASA funding cycles shift.

None of these are SpaceX. None of them will be. But SpaceX just put a $1.75 trillion price tag on what orbital spaceflight is worth. Institutions that missed the IPO will be looking for the next best thing to own. RKLB is the most direct answer to that question.
