SpaceX's IPO sends capital spilling into RKLB, ASTS and LUNR

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

SpaceX's IPO closed as the largest in history, putting a $1.75 trillion price tag on what Elon Musk built from a converted warehouse in Hawthorne, California. For a certain kind of investor, that number is the story. For everyone else, it's the starting gun.

When a company that size goes public, it doesn't just create wealth for its existing holders. It creates a problem for institutional capital. Fund managers who missed SpaceX, or who can't get enough allocation at that valuation, need space exposure somewhere. They have to put it somewhere. And the list of credible public options is short enough to write on a napkin.

Rocket Lab USA (NASDAQ:RKLB) is the most obvious redirect. It's the only other company currently flying an operational orbital rocket. Not planning to. Not testing. Flying. Electron has over 60 launches to its name, and Neutron, the medium-lift vehicle designed to compete with Falcon 9 on small commercial payloads, is on track for first flight. At a fraction of SpaceX's valuation, RKLB becomes the closest thing to a "second launch provider" that an institution can actually buy. The repricing after the SpaceX IPO isn't speculative; it's mechanical. Capital has to go somewhere.

AST SpaceMobile (NASDAQ:ASTS) is a different kind of beneficiary. Its pitch, connecting ordinary smartphones directly to satellites without special hardware, is the same thesis Starlink proved viable. A richly valued, newly public SpaceX is essentially a $1.75 trillion proof-of-concept for the whole satellite connectivity category. ASTS sits one step removed from that validation, building what could become the mobile carrier layer for the 40% of the planet that still has patchy ground coverage.

Then there's Intuitive Machines (NASDAQ:LUNR). This one is more specific. LUNR flies its lunar landers on SpaceX rockets and holds NASA contracts that run into billions. SpaceX going public doesn't just validate the sector, it validates LUNR's own supply chain. Its cost structure depends on Falcon 9 remaining the dominant heavy-lift option, which a freshly capitalized, publicly accountable SpaceX is highly incentivized to maintain.

The bear case on all three is the same: SpaceX going public could compress valuations elsewhere by providing a cleaner, more liquid way to own the dominant player. Why buy RKLB at a premium to fundamentals when you can buy the real thing? That's a fair objection, and it probably applies to some capital that would have gone to the secondaries.

But the institutional math cuts the other way. Most funds have position-size limits. A $1.75 trillion SpaceX is too large a single bet for most mandates. The overflow has to land somewhere, and the three names above are where the space-focused money has to go if it can't get enough SpaceX. That's not a narrative. It's portfolio mechanics.

The window for the repricing to play out is probably measured in weeks, not months. SpaceX's IPO is recent enough that allocations are still being digested. When the dust settles on who got what, watch RKLB first.

Quick Takes

Three more stories worth knowing about

Micron's score drop is worth watching

Micron Technology (NASDAQ:MU) shed 24 points on our scoring model over the last four days. That's a meaningful move for a company that was, until recently, one of the cleaner AI-infrastructure plays in memory. HBM3E demand from Nvidia hasn't slowed, and Micron's own guidance last quarter was constructive. The drop likely reflects positioning ahead of earnings season rather than a fundamental shift. But if MU prints weak on the next report, the memory cycle narrative takes a hit that won't be easy to shake before year-end.

Nu Holdings' pullback is probably a buying pause, not a reversal

Nu Holdings (NYSE:NU) dropped 25 points on our model this week. The Brazil-based digital bank now serves over 100 million customers across Latin America, and its unit economics keep improving as the customer base matures. A score drop at this level usually reflects short-term sentiment, not a change in the underlying trajectory. The real risk to NU isn't competition from local banks, most of which still run on legacy infrastructure. It's FX. A weak Brazilian real compresses dollar-denominated returns fast. Watch the currency, not the headlines.

Kratos is the asymmetric defence name the Golden Dome debate is missing

While Lockheed Martin (NYSE:LMT) and RTX (NYSE:RTX) dominate the Golden Dome conversation, Kratos Defense (NASDAQ:KTOS) is where the asymmetric bet sits. Kratos builds drones, autonomous systems, and low-cost tactical platforms, exactly the kind of distributed, attritable hardware the Pentagon keeps saying it wants more of. LMT and RTX will get the big contracts. KTOS could get the volume. The market cap difference between them means a relatively small reallocation of Golden Dome spending could be a very large event for KTOS shareholders.

Overlooked Stock

CRDO

Credo Technology Group Holding Ltd

Credo Technology (NASDAQ:CRDO) makes the high-speed connectivity chips that move data between servers inside AI data centers, specifically active electrical cables and SerDes IP that handle the throughput problem at scale. It scores 92 on our model and sits in the True North tier, which puts it alongside names getting a lot more attention.

The interesting angle here is what Credo is not. It's not a GPU company, not a memory company, and not a networking giant. It's the small component that becomes a constraint when you're trying to connect 100,000 GPUs in a single cluster. Hyperscalers are already buying. Taiwan Semiconductor is in the supply chain. The customer list reads like a who's who of the companies spending the most on AI infrastructure right now.

At its current valuation, CRDO trades at a fraction of the attention its customers attract. Worth a closer look before that changes.

The Contrarian Take

The SpaceX IPO might be the top of the space investment cycle, not the beginning

The consensus view is that SpaceX going public at $1.75 trillion opens the floodgates for space investing. Capital rushes in, every related stock re-rates, a new era begins.

Here's the other reading. Major IPOs of dominant companies have a history of marking sector peaks, not launchpads. When the most important private company in a category finally goes public at a stratospheric valuation, the remaining upside in the sector is already priced. Retail piles in after the institutional allocation. Sentiment hits maximum enthusiasm. And then the fundamentals have to catch up to a decade of forward expectations, which they rarely do on schedule.

RKLB, ASTS, and LUNR could absolutely re-rate on the SpaceX halo. They could also spend the next 18 months underperforming as investors realize they bought the reflection of a story rather than the story itself. The prudent move is sizing positions to reflect both possibilities, not just the exciting one.
