Summary
Private equity funds reached $4 billion of investment in defense technology growth companies in the first nine months of 2026, compared with $500 million in 2024, according to PitchBook data cited by CNBC. Traditionally buyout-focused investors are increasingly financing younger, high-growth companies. PitchBook counted 15 such growth deals in 2024, 31 in 2025 and 48 in the first nine months of 2026, with growth investments making up 41% of the value of defense PE deals in 2026 compared with 3% in 2024.
The shift reflects broader capital flows into the sector. Startups in NATO countries and allied states raised $27.1 billion in venture funding through September 2026, nearly twice the total for all of 2025, according to a report by Dealroom and Resilience Media. Analysts expect private equity, debt and other sources of capital to play a growing role as technology companies move into industrial production. A White & Case survey of 250 senior executives at UK defense companies found that 97% expect to seek significant external financing over the next 12 months.
Advent International announced in March a commitment of up to $1 billion to next-generation defense technology, including developers of autonomous systems Shield AI and Saronic. Advent Managing Partner Shonnel Malani told CNBC that defense tech valuations are increasingly based on the promise of technology rather than revenue, profit or order books, and that some companies may fail to convert technical development into commercial success, creating a risk of valuation corrections.
PitchBook analyst Jim Corridor expects investor interest to persist, citing rising defense budgets, the need to replenish ammunition stockpiles, and development of drone and counter-drone technologies. PitchBook data show 504 PE defense deals since 2021 but only 101 exits, with IPOs representing 70% of exit value through September 2026.
