NASA ETF Review 2026: Tema Space Innovators — Riding the SpaceX Era
June 20, 2026 · 9 min read
The Tema Space Innovators ETF (ticker: NASA) launched March 30, 2026 and returned approximately 69% in its first 11 weeks — driven by SpaceX's landmark June 2026 IPO and the resulting re-rating of the entire commercial space sector. It holds SpaceX via an SPV, Rocket Lab, AST SpaceMobile, and 40 other companies building the space economy.

Why the SpaceX IPO made NASA the trade of 2026
SpaceX listed on Nasdaq as SPCX on June 12, 2026 at $135/share — the largest IPO in history at a $1.77 trillion valuation. In the months before the IPO, investors flooded into NASA ETF as one of the few funds that held SpaceX pre-IPO exposure via a special purpose vehicle (SPV).
The $2.6 billion in net flows in the two months preceding the IPO tells the story: investors who couldn't or wouldn't buy SpaceX shares in the private secondary market used NASA as their proxy. When SpaceX priced and traded, the ETF's existing SpaceX position appreciated materially, and the broader sector re-rated as the space economy became investable at scale.
But NASA is not just a SpaceX bet — it holds the entire commercial space ecosystem. SpaceX is 8% of the fund; the other 92% spans satellite communications, launch vehicles, Earth observation, space tourism infrastructure, and space technology companies across the globe.
* SpaceX held via SPV at transaction cost; Voyager Technologies is a recently listed space defense company.
What the commercial space economy actually includes
The fund's 41 holdings span four major verticals within the space economy:
Launch & transportation
Rocket Lab (RKLB) is the top position — a publicly traded small-satellite launch provider and spacecraft manufacturer with a growing manifest. SpaceX (via SPV) represents the dominant heavy-lift and reusable launch capability. New launch providers are emerging but none are publicly traded at scale yet.
Satellite communications & broadband
EchoStar, ViaSat, Iridium, and AST SpaceMobile — companies delivering internet, phone, and IoT connectivity via satellite. AST SpaceMobile is particularly high-growth: its BlueBird satellites deliver cellular service directly to standard smartphones, eliminating the need for specialized terminals.
Earth observation & data
Companies including Planet Labs (PL — see our dedicated post) and others that image the Earth and derive analytics. The daily imagery use cases span defense, agriculture, finance, and climate monitoring.
Lunar & deep space
Intuitive Machines (LUNR) has NASA CLPS contracts to deliver cargo to the lunar surface. York Space and Voyager Technologies build government space systems. This category is early-stage but represents the next decade of government space spending.
The SpaceX position — what the SPV means
SpaceX held 1,350,259 common share equivalents valued at approximately $249.8 million as of June 18, 2026, implying a SpaceX market cap of approximately $2.2 trillion at the SPV's transaction cost basis.
Key nuances of the SPV structure:
The SPV position is carried at transaction cost (not marked to current SPCX market price), which may cause NAV to diverge from fair value temporarily
Post-IPO, the fund manager can either convert the SPV to direct SPCX shares or maintain the private structure — management has signaled intent to hold SPCX shares directly once conversion mechanics are complete
SPCX listed at $135 (June 12, 2026) vs the SPV's cost basis — any appreciation flows to NASA ETF holders through NAV
The 8% weight is intentional — keeping SpaceX below 10% of AUM avoids regulatory concentration thresholds
Bull case vs bear case
Bull case:
Commercial space is a generational transition from government monopoly to private market — the companies building this infrastructure could be the railroad stocks of the 21st century
SpaceX's Starlink already generates $8B+ in annual revenue and is only at ~3% global broadband penetration — the growth runway is enormous
AST SpaceMobile (6% weight) is in the early innings of a mobile network that operates from space — if it achieves carrier-grade reliability, it's a trillion-dollar market opportunity
Rocket Lab is growing launch revenue and manufacturing revenue simultaneously — uniquely positioned as a vertically integrated small-space company
Bear case:
69% return in 11 weeks is extraordinary — much of the SpaceX IPO catalyst is now priced in; new buyers are entering at a much higher level than March 2026
0.75% expense ratio is not cheap; a flat or declining space sector erodes returns meaningfully vs owning stocks directly
Several holdings (Intuitive Machines, AST SpaceMobile, York Space) are pre-revenue or early revenue — high binary risk at the individual position level
EchoStar and ViaSat face competitive pressure from SpaceX's Starlink — owning both the predator and the prey in the same fund creates tension
Active management with limited track record — 11 weeks is too short to evaluate stock-selection skill
