$14.6 billion has already flowed into defense tech startups in 2026, surpassing the sector’s full-year 2025 record with seven months still left.
Anduril drove much of the surge with a $5 billion Series H at a $30.5 billion valuation, while Shield AI raised $2 billion and Saronic secured $1.75 billion.
Deal count has not exploded at the same pace: 107 rounds have been announced so far this year, only slightly ahead of 2025’s 206-round pace, showing capital concentrating in larger bets.
Investors are backing AI military systems, autonomous aircraft and vessels, defense software, and dual-use space infrastructure, with Mach Industries adding a $300 million round announced Monday.
Attention is now shifting to exits after drone startup Swarmer’s shares jumped more than 500% on debut, with Anduril and nearly four dozen peers seen as potential IPO candidates.
