Goldman Sachs calls it “The Second Space Age” — a structural shift in which space is shedding its identity as a government prestige project and becoming a pillar of the industrial economy. The firm projects the global space economy will reach $1.8 trillion by 2035, driven by collapsing launch costs, surging private capital, and a wide-open runway for public-market funding.
More than $55 billion flowed into the space ecosystem in 2025, and the first quarter of 2026 alone brought a record $36 billion of investment. Aerospace companies have raised a cumulative $89 billion through IPOs since the start of 2025 — a wave Goldman describes as the “broader institutionalization of space as a distinct industry within the public equity market”.
This article examines three small-cap equities riding this wave — Universal Display Corporation (NASDAQ: OLED), AST SpaceMobile (NASDAQ: ASTS), and Rocket Lab USA (NASDAQ: RKLB) — through the lens of their unique positioning, underlying financials, and the material risks that could derail the thesis.
The Three Tiny Stocks
1. Universal Display Corporation (OLED): The Materials Monopolist with Tangential Space Exposure
What it does: Universal Display is the dominant supplier of phosphorescent OLED materials and technology licensing to display manufacturers globally. Its revenue is tied primarily to smartphone, TV, and IT display markets — not space. The company holds over 500 issued and pending patents for phosphorescent OLED commercialization.
Space connection: The link is indirect. Space-grade OLED displays are being developed for satellite command terminals, payload data visualization, and astronaut interfaces. Chinese display giant BOE supplies space-grade reinforced screens to satellite manufacturers including Galaxy Space and China Aerospace Science and Technology Corporation. Universal Display’s materials ultimately feed into these supply chains, but space represents a negligible fraction of current revenue.

Analyst Outlook: Roth Capital analyst Scott Searle maintains a Buy rating with a $180 target. 2026 OLED surface area growth is modest at about 4%, but the setup improves materially in 2027 as new 8.6-generation capacity comes online. Blue emitter commercialization could add $250 million+ in revenue and $2.50+ in incremental EPS by 2030. At roughly 11x 2027 earnings estimates, net of ~$20/share in cash, valuation is at a level not seen in at least five years.
Risk Factors:
Risk Category
Detail
Demand Environment
“More cautious demand environment, higher component costs and supply constraints”
Guidance Cut
FY2026 revenue guidance lowered to $630M–$670M from $650M–$700M
Royalty Pressure
Royalty and licensing revenues dropped 26.3% YoY due to customer mix shifts
Macro Sensitivity
Recovery timing in OLED adoption, especially in smartphones, remains uncertain
Space Exposure
Minimal — space is a negligible revenue contributor
Verdict: OLED is fundamentally a display-materials play, not a pure space stock. Its inclusion in a “space economy” basket requires a generous definition of adjacency.
2. AST SpaceMobile (ASTS): The Direct-to-Smartphone Moonshot
What it does: AST SpaceMobile is building a space-based cellular broadband network designed to connect directly to standard, unmodified smartphones using spectrum from mobile network operators — eliminating the need for specialized satellite phones or ground terminals.
Analyst Outlook: Berenberg initiated coverage with a Buy rating and $92 price target in September 2026. Analyst consensus stands at Hold with an average target of $79.61. The stock trades at roughly 9.5x price-to-book versus a telecom sector average near 1.8x. Over the trailing 12 months, insiders liquidated more than $450 million worth of ASTS while buying only $187,240 worth of stock.
Verdict: ASTS is a high-conviction, high-risk infrastructure bet. The technology, if it works at scale, could be transformative. But the gap between current revenue ($115.3M TTM) and the capital required to build a 90+ satellite constellation is enormous, and dilution risk is acute.
3. Rocket Lab USA (RKLB): The Vertically Integrated Challenger
What it does: Rocket Lab operates the Electron small orbital rocket and is developing the medium-lift Neutron vehicle. It is also a significant space systems provider, manufacturing satellite components, solar panels, and flight software. The pending acquisition of Iridium Communications would add a 66-satellite network and 2.5 million subscribers.

Analyst Outlook: Wall Street remains bullish with a Strong Buy rating and $110.93–$111.00 average target, implying ~76% upside from ~$63 levels. However, the multiple rests on a launch vehicle that has yet to fly and an acquisition that has yet to close. The stock trades at ~49.6x TTM sales, well above Intuitive Machines (~6.9x) but below AST SpaceMobile (~210x).
Verdict: Rocket Lab has the strongest current revenue base and backlog of the three. But the valuation is pricing in flawless execution of Neutron and Iridium — two binary events that could each move the stock materially in either direction.

Conclusion
The Second Space Age is real, and its structural drivers — collapsing launch costs, defense spending, AI convergence, and public-market institutionalization — are durable. But the three stocks examined here occupy very different positions on the risk-return spectrum:

The space economy is not a monolith. It is a layered ecosystem — launch, manufacturing, orbital infrastructure, data services — and value will concentrate at the chokepoints. Investors should distinguish between companies that enable the space economy and those that merely participate in it. The former may command premium multiples; the latter may struggle to justify them.
