Venture capital’s once-tentative relationship with defense technology has transformed into one of the hottest bets in startup investing. Through the first five months of 2026, defense tech startups have already pulled in more than $14.6 billion in venture funding — obliterating the previous full-year record of $9.6 billion set just last year.
The numbers tell a dramatic story of sector acceleration. Global defense tech funding hovered between $1.6 billion and $3.9 billion annually from 2020 through 2024. Then came 2025’s breakout, followed by what is shaping up to be a historic 2026. Deal volume has remained relatively steady at around 107 rounds so far this year, but check sizes have ballooned as investors concentrate capital into fewer, larger bets.
Megarounds define the new landscape
The single biggest driver of this year’s surge is Anduril Industries. The Costa Mesa, California-based defense tech giant closed a $5 billion Series H in May at a $30.5 billion valuation, cementing its position as the most valuable venture-backed defense startup on the planet. But Anduril is far from alone in commanding nine-figure rounds.
Autonomous aviation startup Shield AI raised a $2 billion Series G in March led by Advent International and JPMorgan Chase. Naval drone maker Saronic secured $1.75 billion in a Series D round led by Kleiner Perkins later that same month. And just today, autonomous drone systems manufacturer Mach Industries announced a $300 million Series C at a $1.8 billion valuation, backed by Infinite Capital and Ribbit Capital.
Space-related defense plays are also drawing heavy investment. True Anomaly, Sierra Space, and Vast rank among the largest defense-adjacent funding recipients of 2026, reflecting sustained investor appetite for technologies that serve both commercial and national security markets.
The exit question looms
With so much capital concentrated in the sector, attention is rapidly turning to how investors will realize returns. The early evidence is promising: AI drone company Swarmer went public earlier this year, with shares surging more than 500% on debut day and holding near their peak through early June.
Anduril is widely seen as the most anticipated defense tech IPO candidate in the pipeline. A successful public listing at its scale would provide a critical signal to the broader market about public appetite for next-generation defense contractors. Crunchbase’s predictive intelligence tools flag nearly four dozen companies in the military, national security, and law enforcement sectors as likely or probable IPO candidates, including Shield AI, True Anomaly, Sierra Space, and Chaos Industries.
What this means for founders
The defense tech gold rush presents a unique moment for startup founders. While AI and software continue to dominate headlines, the defense sector is demonstrating that hardware-intensive, mission-critical technology companies can command valuations on par with pure-play software businesses.
For early-stage founders, the key takeaway is that deep-tech, hard-science problems are back in vogue. Investors who once shied away from regulatory complexity and long sales cycles are now leaning in — particularly for technologies that can serve dual-use commercial and defense applications.
However, the concentration of capital in megadeals also means that differentiation matters more than ever. The companies commanding the largest rounds aren’t just defense contractors; they’re platform builders with proprietary AI, autonomous systems, and manufacturing capabilities that create genuine moats.
As the defense tech funding cycle matures, founders should pay close attention to the IPO pipeline. If Anduril and its peers successfully navigate the public markets, it could open the floodgates for a wave of exits that redefine how investors think about this once-taboo sector.
