SpaceX's $1.75T IPO makes RKLB look cheap

SpaceX is public at $1.75 trillion. Here's who gets repriced next.

The largest IPO in history closed in June, and the number that came with it deserves a moment of consideration. SpaceX listed at a $1.75 trillion valuation. For context, that puts it ahead of every European stock market combined, and within shouting distance of Saudi Aramco's peak. It is the kind of number that reorders the mental map of what a space company can be worth.

The problem for institutions is supply. You cannot buy $1.75 trillion worth of SpaceX without being SpaceX. The float is thin, the valuation is enormous, and every fund manager who missed the private rounds is now sitting on a mandate to get space exposure with nowhere obvious to put it.

That is not a metaphor for opportunity. It is a mechanical description of capital flows.

Rocket Lab USA (NASDAQ:RKLB) is the most direct beneficiary. It is the only other company on public markets flying an operational orbital rocket with a real cadence of launches. Its Neutron rocket, targeting medium-lift payloads, is scheduled for its first launch before the end of 2026. Institutions that want something resembling launch-company exposure and cannot get enough SpaceX at a sensible entry point will look at RKLB. That was true before the IPO. It is considerably more true now.

AST SpaceMobile (NASDAQ:ASTS) sits on a different part of the thesis. Starlink proved that space-based connectivity is a real business, not a science project. AST is building the consumer version of that, direct-to-phone broadband that works with the handset already in your pocket. The technology is harder than Starlink in some ways and easier in others. What SpaceX's valuation does for ASTS is validate the entire demand curve. A $1.75 trillion market cap is the market saying that space connectivity is worth trillions. ASTS is building inside that same addressable market.

The more unusual angle is Intuitive Machines (NASDAQ:LUNR). It does not compete with SpaceX. It depends on SpaceX, flying its lunar landers on Falcon 9 rockets under NASA contracts that collectively run into the billions. When SpaceX reprices as a category-defining company, LUNR reprices as the company that SpaceX enables. It is a customer-supplier relationship, and the customer just became one of the most valuable companies on the planet.

The bear case on all three is straightforward. SpaceX's IPO sucks attention toward the primary, not the secondaries. Retail flows chase the headline name. Institutional capital is slower to rotate. If Neutron's schedule slips, RKLB loses its near-term catalyst. If AST's network build hits power or interference problems at scale, the SpaceX halo does not save it.

But the repricing logic holds regardless of those risks, because it is not about earnings. It is about the reference point. Before June 2026, there was no publicly traded orbital launch company valued at anything approaching this scale. Now there is, and every analyst building a comps table for RKLB is using a very different denominator than they were twelve months ago.

The SpaceX IPO did not just create liquidity for early investors. It created a benchmark. And benchmarks, once set, pull everything in their gravity well.

Quick Takes

Three more stories worth knowing about

The Golden Dome budget is real money, not a talking point

Washington's missile defense push has moved from White House slide decks into actual appropriations. Lockheed Martin (NYSE:LMT), RTX (NYSE:RTX), and Kratos Defense (NASDAQ:KTOS) are all sitting inside existing program contracts, not lobbying for future ones. The distinction matters. Companies lobbying for future spending are a bet on politics. Companies already billing against funded contracts are a bet on execution. LMT and RTX are the former; KTOS, with its lower-cost autonomous systems, is the more interesting risk-reward if the Pentagon's stated preference for distributed, expendable platforms holds through the procurement cycle.

Anthropic's IPO sets the floor for every AI-native stock

Anthropic filed confidentially in June and is targeting a public listing this fall. The valuation being discussed in private markets is north of $100 billion. When that number becomes a public reference point, every AI-native software company gets a new comps table. SoundHound AI (NASDAQ:SOUN), UiPath (NYSE:PATH), and Serve Robotics (NASDAQ:SERV) are three names that sit in the direct path of that repricing. The mechanism is the same as SpaceX and space stocks: a flagship listing creates a benchmark, and benchmarks pull adjacent valuations. OpenAI is reportedly targeting 2027. Between now and then, the window for the second-tier names is open.

NU and AAOI both moving hard. Two very different reasons.

Nu Holdings (NYSE:NU) scoring 84 with a 25-point delta over four days is consistent with a thesis that has been building for a while. The Brazilian digital bank now has over 100 million customers and is expanding into Mexico and Colombia. Revenue growth is still north of 50% year-on-year. The score move reflects momentum catching up with fundamentals. AAOI, Applied Optoelectronics (NASDAQ:AAOI), is a different animal. An 89 score with a 17-point delta in a small-cap optical components name in this environment probably means a hyperscaler order rumor or a supply deal. Worth watching the tape closely before assuming the move is fundamental.

Overlooked Stock

KSPI

Joint Stock Company Kaspi.kz

Kaspi.kz (NASDAQ:KSPI) is scoring 96 on our system, the highest in this set, and most Western investors have never heard of it. The company runs payments, a marketplace, and fintech products across Kazakhstan, Azerbaijan, and Ukraine, operating more like a super-app in the WeChat mold than anything that has a clean US analog. Payments, e-commerce, travel booking, buy-now-pay-later, merchant finance, all inside one platform, in a market where Kaspi effectively is the digital financial system for millions of people. The Kazakhstan economy is growing at roughly 5% a year and is heavily tied to commodity export revenues. The Ukraine exposure is the obvious risk and deserves proper due diligence before any position. But a 96 score on a True North tier company that most of the US market has never looked at is worth an afternoon of reading.

The Contrarian Take

AI lab IPOs might be the worst thing that happens to AI stocks this year

The consensus is that Anthropic going public pulls the entire AI sector higher. More attention, more capital, more validation. The second-order read is messier. When the labs are private, there is no public benchmark for AI profitability. The moment Anthropic files its S-1, it will show investors exactly how expensive it is to run frontier models, how thin the margins are on API revenue, and how capital-intensive the compute requirements remain. OpenAI's numbers, when they eventually surface, will likely say the same thing. The risk is not that the IPOs fail. It is that they succeed at the wrong valuation and force every AI-adjacent stock to be measured against companies that are, for now, structurally unprofitable at scale. Validation cuts both ways. The smart trade might be to own AI-native applications before the filing, then reassess once the S-1 shows everyone what the economics actually look like.
