Investors experienced a tumultuous day in the space industry as SpaceX debuted on the stock market, surging nearly 19% in its first session. However, this positive momentum seemed to overshadow a significant downturn for several smaller public space companies, including Rocket Lab, AST SpaceMobile, and Intuitive Machines, which all saw their shares decline substantially.
Analysts have proposed a few explanations for this divergent performance. One theory suggests a rotation in investor interest. With demand for SpaceX shares soaring, investors may have sold off their holdings in other space stocks to reallocate funds to the newly public giant. If this hypothesis holds true, the declines in these companies’ stock prices could be less about their individual fundamentals and more about a temporary shift in market sentiment.
Nonetheless, some market watchers are suggesting that the declines may reflect a more fundamental reassessment of how these smaller companies compare to their vastly more established competitor, SpaceX.
Rocket Lab (NASDAQ: RKLB) was hit the least, falling more than 10%. On the same day, the company announced it would join the Nasdaq-100 index later this month—a milestone that often attracts interest from index funds. Possessing the most established business among the trio, Rocket Lab provides small-rocket launch services and is actively growing its space systems segment, which produces satellites and spacecraft components. With a significant revenue increase of 63.5% year-over-year in Q1 2026, Rocket Lab is also working on a larger launch vehicle, Neutron, aimed at accommodating heavier payloads. However, some investors remain concerned about the stock’s high valuation, trading at approximately 80 times its revenues despite the ongoing losses.
AST SpaceMobile (NASDAQ: ASTS) suffered the most severe drop, plummeting over 15%. This company is focused on creating a satellite network intended to deliver broadband directly to smartphones. While its vision is ambitious, it remains largely in the conceptual phase, which is evident in its financials—reporting just $14.7 million in revenue in the first quarter. With market valuations in the tens of billions and a price-to-sales ratio in the hundreds, investors are wary. Despite holding over $3 billion in cash to support its ambitious satellite constellation project, AST SpaceMobile is burning through funds and faces skepticism regarding its model’s viability. Notably, it relies on SpaceX rockets for satellite launches, highlighting an ironic dependence on its much larger competitor.
Intuitive Machines (NASDAQ: LUNR) experienced a decline of about 13%. This lunar-focused company is distinct in reporting substantial revenue, totaling around $187 million in the first quarter, nearly tripling its figures from the previous year, boosted by its acquisition of satellite builder Lanteris. It also boasts a backlog worth about $1.1 billion, primarily from NASA and national security contracts, which provides some visibility for future revenues. However, its stock valuation, at about $4.3 billion for $187 million in sales, raises concerns about its affordability. Additionally, a recent announcement regarding a potential stock sale of up to $500 million would further dilute existing shareholder interests, complicating its appeal.
As investors weigh these developments, questions arise: Is this drop a temporary reaction to the excitement surrounding SpaceX, or does it represent deeper concerns regarding the valuations and future prospects of these smaller companies? While Rocket Lab offers a comparatively stable business model, Intuitive Machines appears riskier with its dependence on government contracts, and AST SpaceMobile is still far from proving its revenue-generating potential.
Overall, the market reaction could be indicative of overdue corrections in overvalued stocks, suggesting that while the sell-off may present a buying opportunity, caution is warranted. For those considering investments in Rocket Lab or its peers, thorough analysis is essential as the excitement around SpaceX fades and the reality of these companies’ financial standings comes into sharper focus.
