Best Space Tech (2026)

Space tech is experiencing its second golden age. SpaceX proved the market; now hundreds of startups are filling the value chain. Rocket Lab ($6B), Relativity Space ($4B), and Planet Labs ($2B) are publicly traded, while private companies like Impulse Space, Varda Space, and Vast are building the next layer of orbital infrastructure. The economics have fundamentally shifted. SpaceX's Falcon 9 reduced launch costs from $50,000/kg to under $3,000/kg, and Starship promises $200/kg. This 250x cost reduction is the equivalent of the internet's bandwidth explosion, it enables entirely new business models. Satellite constellations for broadband (Starlink, Kuiper), Earth observation (Planet, Capella Space), and direct-to-device connectivity (AST SpaceMobile, Lynk Global) are billion-dollar opportunities that didn't exist a decade ago. The next frontier is in-space manufacturing (Varda Space Industries), space stations (Vast, Axiom), and lunar infrastructure. Defense spending is also accelerating: the US Space Force budget exceeded $30B, and the Space Development Agency is deploying hundreds of satellites. The winners will be vertically integrated companies that own both the hardware and the data/software layer, not just launch providers, but platforms.
