Key findings

A quarter set by five rounds and one acquisition

Published counts of defence technology investment differ by a factor of five for the same year. This report reads the quarter deal by deal and keeps civil companies and state capital apart from the headline totals.

01 · VENTURE FUNDING

32 rounds of $100M or more took 90%

Mistral AI's $3.5B alone is 19% of the total and decides two headline comparisons. Another $6.6B went to civil companies on the same technology base and stays outside every figure.

02 · SECTORS

Uncrewed systems took 54% of defence money

Drones, autonomy, counter-drone and naval raised $5.1B in 46 rounds. Counter-drone had 18 rounds and 3% of capital. Space and ISR led once Mistral AI is set aside.

03 · REGIONS

Europe $8.8B, the United States $9.1B

Four rounds supply 80% of the European total. Without Mistral AI the American lead is $3.8B, and the median European round is under two fifths of the American one.

04 · INVESTORS

550 investors, 85 backed more than one company

Khosla Ventures led with nine companies. At least 33 rounds had a corporate investor, 20 a state-backed one and 21 a defence specialist fund.

05 · STATE AND FUND CAPITAL

$3.1B in six defence fund closes

Four of the six closes are European. US Department of Defense equity and loan commitments are counted apart: none of it is venture capital.

06 · M&A AND EXITS

One deal is 39% of disclosed value

GE Aerospace's $11.75B purchase of a castings maker. Private equity sold 63% of the disclosed value to strategic buyers, and one US defence IPO priced below its range.
