Forget SpaceX. These 2 Space Stocks Could Be the Real Winners Of the Coming IPO Frenzy

Rocket Lab reported Q1 revenue of $200.3 million, up 63.5% year over year, while backlog more than doubled to $2.2 billion and it booked 31 new launch contracts, including a $190 million U.S. Department of War order. AST SpaceMobile also gained momentum with FCC approval for commercial U.S. service, $1.2 billion+ in contracted revenue commitments, and 2026 revenue guidance of $150 million to $200 million. The article argues that SpaceX IPO speculation is lifting sentiment across the space sector, though both names still carry high execution risk and rich valuations.

Analysis

The key second-order effect is that a SpaceX IPO would act less like a direct competitor event and more like a category-marking mechanism that forces public-market capital to re-underwrite the entire space stack. That tends to favor the “picks-and-shovels” names first: launch capacity, satellite manufacturing, and defense-adjacent test services should see the earliest multiple expansion because they can be framed as enabling infrastructure rather than pure concept risk. The strongest near-term beneficiary is likely the company with the clearest contract-backed revenue conversion, because IPO-led enthusiasm usually compresses time horizons and rewards visible backlog over distant optionality.

The market is likely underestimating how fragile these reratings are once the narrative shifts from story to execution. For Rocket Lab, the next inflection is not revenue growth alone but whether Neutron de-risks enough to justify a higher terminal multiple; until then, the stock is increasingly trading like a long-duration venture asset in a public wrapper, which makes it highly sensitive to any launch slip or guidance disappointment. For ASTS, the regulatory win improves the investability of the thesis, but the real catalyst is subscriber monetization and deployment cadence; any satellite loss or launch delay matters more now because the stock is pricing a much faster transition from permission to revenue.

The contrarian view is that the SpaceX IPO may actually be a sell-the-news event for the sector if it broadens attention faster than fundamentals can catch up. A mega-cap SpaceX listing could siphon incremental capital away from smaller names by creating a more obvious, higher-quality benchmark for private and public space exposure. That creates a potentially sharp dispersion trade: the higher-beta, pre-scale names can keep rerating in the run-up, but they may de-rate quickly once investors anchor to SpaceX’s scale, lower perceived execution risk, and likely index inclusion overhangs.

From a timing standpoint, the next 2-6 weeks matter most for sentiment, while the next 2-6 months matter for proof points. If the IPO pricing is confirmed and launch activity stays clean, momentum can extend; if one of the satellites/launch stories stumbles, the sector’s valuation premium is vulnerable because the stocks have already pulled forward a lot of expected good news.

Key Decisions for Investors

• Long ASTS / short a basket of lower-quality space small caps for 1-3 months: ASTS has the cleanest regulatory catalyst, but hedge the beta because sector enthusiasm can fade quickly if the IPO becomes a benchmark event rather than a broad tailwind.
• Buy RKLB on pullbacks only, preferably after event risk clears, with a 3-6 month horizon: the trade works if investors keep paying for backlog and defense exposure, but downside is meaningful if Neutron timelines slip or the market starts valuing it on near-term sales again.
• Consider a small tactical long in ASTS calls into the FCC/capex narrative, but keep size modest: asymmetric upside if deployment cadence surprises, but the position should be defined-risk because launch or hardware setbacks can cut the multiple fast.
• Pair long RKLB vs short a more speculative satellite-exposure proxy if available: the market is likely to keep rewarding revenue visibility over pure optionality, and Rocket Lab’s contract base gives it better downside support than concept-only peers.
• Take profits into the IPO headline window rather than waiting for the listing: the highest-probability alpha is in the anticipation phase, while the actual debut could trigger mean reversion if the sector becomes overcrowded and valuation discipline returns.
