Investors are piling into space startups after SpaceX's record-breaking IPO, with venture funding for US space-tech firms excluding SpaceX reaching $7.1 billion in 2025.
Companies like Observable Space, Northwood Space, and CesiumAstro have recently raised significant amounts of capital, with CesiumAstro securing $470 million in equity and financing.
Executives and investors say the space sector has demonstrated its ability to deliver, making it more attractive to big venture investors.
However, the sector also comes with risks, including the challenges of building devices capable of operating in orbit and the potential for startups to fail.
Despite these risks, many space startups are pairing real demand with calculated bets on developing technology, with some already showing traction among commercial and government customers.
