Private equity locks onto defence tech as geopolitical tensions fuel a surge in investment - but is it a boom or a bubble?
Private equity is taking aim at the defence technology sector, with investment surging as geopolitical tensions and rising military budgets create a new market for capital. According to PitchBook, PE growth investments in defence reached $4bn in the first nine months of 2026, up from just $500mn in 2024, while the number of deals climbed from 15 to 48 over the same period. The shift is bringing buyout firms onto territory traditionally occupied by venture capital, backing businesses developing everything from autonomous drones and missile defence systems to satellite technology. Advent International has committed up to $1bn to next-generation defence technology, while other investors, including French PE house Weinberg Capital Partners, are targeting established, profitable suppliers with opportunities to scale production and consolidate fragmented supply chains. But the rush to rearm portfolios comes with risks: valuations are climbing, exits remain relatively scarce and some investors are already warning of bubble territory. With private capital increasingly locked, loaded and ready to deploy, the question is whether these investments will hit their targets or prove a costly misfire.
