Global space investment reached an all-time high of $3.5 billion in Q3 2025, driven by a new wave of startups and steady government defense spending, according to Seraphim Space.
The figure nearly doubles last year’s total and reflects a maturing, more diverse market, analysts said. “Historically, most of the capital was concentrated in just a couple of players, SpaceX and OneWeb,” said Lucas Bishop of Seraphim. “Now we’re seeing a far wider set of investable companies.”
Defense-oriented aerospace firms such as Hadrian, Apex, and Hermeus led top U.S. rounds, while China’s Galactic Energy closed a $336 million funding. Governments in the U.S., Europe, and China are accelerating support for domestic space capabilities, fueling interest in dual-use technologies that serve both civil and military applications.
The report highlights growing investor appetite for low-Earth-orbit satellites, hypersonic systems, and communications constellations. Public space stocks have rallied in parallel — Rocket Lab and Planet Labs have doubled in value, and AST SpaceMobile tripled after demonstrating satellite-to-phone broadband.
