Defense technology startups are on a tear. If that wasn’t already obvious, it became clear this week when shares of AI drone company Swarmer soared 520% in their first day of trading on the Nasdaq.

Swarmer’s debut is modest by tech IPO standards. The Austin, Texas-based startup sold 3 million shares at $5 apiece, raising about $15 million in the process and giving it an initial market cap of $60 million. But by the close on Tuesday, its market cap had soared to more than $382 million.

Its IPO, of course, comes at a prescient time, with the U.S.’ war in Iran spiraling into a larger regional conflict even as the Russia-Ukraine war continues into its fifth year.

Public-market investors’ reception for Swarmer mirrors the fervor with which venture investors have backed defense tech startups in recent years. Investment to venture-backed companies in the sector — which we define as the industries of military, national security and law enforcement — topped $8.4 billion last year, an all-time record and more than double 2024’s total, per Crunchbase data.

Among 2025’s top venture-funded defense companies were Southern California-based Anduril Industries, which raised a $2.5 billion Series G led by Founders Fund; Germany-based Helsing, which raised about $693 million in a round led by General Catalyst, Accel, Lightspeed Venture Partners and other investors; and Austin-based Saronic, a maker of unmanned maritime security vessels that raised $600 million in an Elad Gil-led round.
