Which space companies are publicly traded?

Publicly traded space companies as of 2026 include the established defence primes (Lockheed Martin, Northrop Grumman, Boeing, L3Harris, RTX), pure-play space companies that went public via SPAC or IPO (Rocket Lab, AST SpaceMobile, Planet, BlackSky, Iridium, Viasat, Maxar), and a growing slate of international operators (Eutelsat-OneWeb, ISpace, SES, Inmarsat). The live list on Space Index links to each company's profile.

The list of publicly traded space companies grew substantially during the 2020-2022 SPAC wave, contracted as several de-SPACs underperformed and were delisted, and stabilised around a core group as of 2026.

Why the public-private split matters

Some of the most active space companies (SpaceX, Blue Origin, Stoke Space, Anduril, Hadrian, Vast, Impulse Space, Astranis) are still privately held. Public-market valuations therefore capture only part of the industry. Newer pure-play IPOs are expected as the SPAC-de-listing cycle settles and reusable launch reduces capex risk.
