SpaceX's IPO just repriced RKLB, ASTS and LUNR

SpaceX went public at $1.75 trillion. Here's where the money goes next.

SpaceX's IPO in June 2026 was the largest in history. That's the headline. The more interesting story is what happens to every dollar that wanted SpaceX exposure but couldn't get it before the listing.

Institutions that missed the private rounds are now sitting on approved mandates for 'space exposure' with very few places to put the money. SpaceX at $1.75 trillion is already priced for a fairly extraordinary future. That leaves three public names doing most of the work of absorbing new capital, and each of them is a different bet on how the space economy actually develops.

Rocket Lab USA (NASDAQ:RKLB) is the most direct translation. It's the only other company flying an operational orbital rocket on a commercial basis. The Electron rocket has over 50 launches behind it. Neutron, the medium-lift vehicle targeting the same market SpaceX's Falcon 9 dominates, is in development. When fund managers screen for 'launch company that isn't SpaceX,' RKLB is the answer. It was before the IPO. It's more so now.

AST SpaceMobile (NASDAQ:ASTS) is a different thesis entirely. SpaceX proved that satellite connectivity works at scale through Starlink. ASTS is building the version that connects directly to an unmodified smartphone, no special hardware required. The total addressable market is everyone on earth with a phone and a patchy signal, which is most of them. A richly valued, newly public SpaceX validates the entire satellite-connectivity model and makes the ASTS story easier for a generalist portfolio manager to sell internally.

Intuitive Machines (NASDAQ:LUNR) is the strangest of the three because its upside is partly tied to SpaceX doing well. LUNR flies its lunar landers on SpaceX Falcon 9 rockets and holds NASA contracts for lunar surface delivery. As SpaceX's public profile grows and NASA's Artemis program inches forward, LUNR is a direct beneficiary of both. The risk is that the NASA budget stays under pressure, which it has been. But the contract base is real and the relationship with SpaceX as launch provider creates a kind of structural alignment you don't often see between two public companies.

The second-order effect worth thinking through: SpaceX going public doesn't just create capital flows. It creates a pricing benchmark. Every analyst covering RKLB, ASTS, or LUNR now has a $1.75 trillion comparable sitting in their model. That doesn't mean any of them get to that number, but it does mean the ceiling on what 'space' is worth got reset dramatically higher in June. Institutional price targets follow comparables. The repricing of the smaller names doesn't require them to match SpaceX, just to be taken more seriously in the same category.

The honest bear case: most of this is reflexive capital flow rather than fundamental rerating. If SpaceX's stock drops 30% in its first year as a public company, the halo effect reverses and the smaller names get sold first. That's how it worked with the EV sector after Tesla's peak, and there's no obvious reason space would be different.

But if SpaceX holds its valuation and Starlink keeps adding subscribers, the benchmark holds, and RKLB in particular has a credible path to being the second orbital launch company the world actually needs.

Quick Takes

Three more stories worth knowing about

Anthropic's IPO is coming. Three names are already moving.

Anthropic filed confidentially for an IPO in June 2026 and is targeting a fall listing. The pattern from SpaceX is fresh in every portfolio manager's mind: if you don't own the private company, you buy the closest public proxies before the listing, not after. SoundHound AI (NASDAQ:SOUN), UiPath (NYSE:PATH), and Serve Robotics (NASDAQ:SERV) are the names in that conversation. SOUN is the pure-play voice AI application layer. PATH is how enterprises actually deploy AI into real workflows. SERV is the physical-world proof of concept, Nvidia-backed autonomous delivery robots already operating at commercial scale. The thesis on all three is the same: a trillion-dollar AI-lab listing pulls every AI-adjacent stock's valuation ceiling higher.

Golden Dome defence spending has a short list of winners

Washington is moving tens of billions toward missile defence and layered homeland protection under the Golden Dome program. The spending is real and the contracts are starting to flow. Lockheed Martin (NYSE:LMT) and RTX (NYSE:RTX) are the obvious institutional buys because they already sit inside the program's architecture, interceptors, sensors, command systems. The more interesting bet is Kratos Defense (NASDAQ:KTOS), the smaller-cap play on autonomous drones and distributed defence systems. If Golden Dome expands beyond traditional interceptors into the kind of lower-cost, networked threat response the Pentagon has been talking about for years, KTOS gets repriced harder than either of the primes.

Micron's score drop is worth watching closely

Micron Technology (NASDAQ:MU) dropped 25 points in our scoring over four days. That's a sharp move. MU has been one of the cleaner AI infrastructure plays because high-bandwidth memory demand for next-generation GPU clusters runs directly through Micron's HBM roadmap. A score drop of this size usually reflects earnings risk, guidance anxiety, or both. Micron's fiscal Q3 2026 results are the reference point. If HBM shipments came in below what the market had baked in, the AI memory thesis gets stress-tested. Worth watching the earnings transcript carefully for anything management says about HBM4 ramp timing.

Overlooked Stock

CLS

Celestica Inc.

Celestica (NYSE:CLS) scores 93 in our system, True North tier, and still flies under most retail radar despite doing something very specific that the AI buildout needs badly: it builds the physical hardware platforms that hyperscalers actually rack in their data centers. Not the chips, not the software, the server and networking chassis, the thermal management, the rack-scale integration. Celestica has a strategic collaboration with AMD (NASDAQ:AMD) on Helios, a rack-scale AI platform. That's not a press-release partnership. That's a design-and-manufacturing relationship on the kind of dense AI compute infrastructure that hyperscalers are ordering in volume. Revenue grew 63% year-over-year in Q4 2025. The stock trades at a fraction of Nvidia's multiple despite being a direct enabler of the same capex wave. The risk is margin compression if hyperscalers push harder on pricing. But at current levels, Celestica looks like a company the market is still underpricing relative to what it actually does.

The Contrarian Take

The SpaceX IPO didn't validate the space sector. It might have peaked it.

The consensus take is that SpaceX going public at $1.75 trillion opens the door for every other space company. Capital floods in, multiples expand, RKLB and ASTS ride the wave. I've laid out why that argument has real logic behind it. But here's the version that keeps me honest.

Every sector peak in recent memory followed the same pattern: the dominant private company finally goes public at an enormous valuation, institutional FOMO peaks, and the marginal dollar that was waiting for 'exposure' finally gets deployed, right at the top. Dot-com had it. EVs had it with Rivian's 2021 listing. Crypto had it with Coinbase in April 2021, almost exactly at Bitcoin's first 2021 high.

If SpaceX at $1.75 trillion is the moment the space trade becomes consensus, it may also be the moment the easy money is already made. The smaller names get bought because of the benchmark, not because their own fundamentals changed. That's a fragile bid. When the benchmark corrects, the proxies correct faster.
