Defense, Space Startups Seek SPAC Listings as Investor Interest Rises

Growing investor interest in defense, space and satellite technology is driving a surge in public-market listings by early-stage companies, particularly through special purpose acquisition companies (SPACs). Six companies in these sectors have announced SPAC mergers in 2026—twice the total for all of 2025 and about 10% of this year’s SPAC deals—while at least seven others have pursued traditional initial public offerings. SPACs allow companies to negotiate valuations and secure financing before listing, an advantage for businesses with long development cycles and unpredictable government-contract revenue. Ursa Major’s planned $2.3 billion merger is intended to fund expanded domestic production of propulsion systems for missiles and launch vehicles, while companies such as Quantum Space and Elroy Air are pursuing space and autonomous-aircraft markets. The strategy offers faster access to capital but carries risks including limited revenue, dependence on government contracts, shareholder dilution and potentially less scrutiny than a conventional IPO.
