Two space-focused ETFs charge identical expense ratios but target different segments of the commercial space economy.
ARK Space & Defense Innovation ETF (ARKX) and Tema Space Innovators ETF (NASA) both carry a 0.75% expense ratio, eliminating cost as a differentiator for investors. The funds provide exposure to the expanding commercial space sector but employ distinct strategies and sub-sector focuses.
Tema Space Innovators ETF, launched in 2026, holds 38 securities and emphasizes satellite operations and launch services. Its top holdings include SpaceX (20.14%), Rocket Lab (11.09%), and Viasat (6.18%). The fund uses fundamental research to identify companies deriving significant revenue from the space value chain.
ARKX, in contrast, targets orbital and defense innovation, though specific holdings were not detailed. The choice between the two funds hinges on investor preference for commercial space sub-sectors rather than fee structures.
