Why These Companies
Launch and spacecraft: SpaceX (listed in June 2026), Rocket Lab and Virgin Galactic. Satellite services: AST SpaceMobile aims to connect ordinary phones directly from space. Established contractors: Lockheed Martin, Northrop Grumman, L3Harris and Boeing run satellite, rocket-motor and spacecraft programmes; Kratos provides satellite ground systems. For the established contractors space is a small part of revenue, for the young companies it is nearly all of it; the two can react very differently to the same news.
The list is an editorial selection, not investment advice. It is sorted by market cap; companies whose primary listing is outside the US are left blank because their market cap is not comparable.
