Defense tech funding has doubled this year, and the money is no longer pretending this is a niche corner of venture capital. The hard question is whether investors are backing real procurement demand or paying software multiples for companies that still have to survive government buying cycles.
Defense and security startups have raised $12.3 billion in venture funding since the start of 2026, according to PitchBook data reported by the Financial Times, almost double the same stretch last year and already above the $9.95 billion raised in all of 2025. Dealroom puts the broader year to date figure at $17.4 billion. However you slice the count, the direction is clear: money that used to chase generic AI startups is rotating hard into autonomy and sensor-heavy drones, all with a military customer attached.
The clearest signal landed this week. Bloomberg reported that Expeditions, a Warsaw-based venture firm backed by BAE Systems and the NATO Innovation Fund, closed a €197 million, about $225 million, second fund dedicated to European defense and deep tech startups. Limited partners include the Polish Development Fund and executives from Skype, Wise, Bolt and Snowflake, hardly a roster of defense industry lifers. That is part of the story. Consumer tech money is now underwriting sovereign military hardware.
Five days earlier, the Wall Street Journal reported that Quantum Systems, the German maker of autonomous surveillance drones, raised $1.2 billion at a roughly $8 billion valuation. Airbus, Blackstone, Advent and Noteus Partners co-led the round, with Fidelity among the investors. Quantum Systems, founded in 2015 by former German Air Force pilot Florian Seibel, started out selling drones for civilian jobs including agricultural surveying. It says its systems flew more than 19,000 missions in Ukraine last year.
If you are watching from outside defense, do not miss the shift hiding inside those numbers. Most of what is being funded is not a new tank or a better rifle. It is software wrapped around hardware: drones that collect and interpret battlefield data, ships that can move without crews, platforms that fuse sensors into a usable picture. Anduril sells Lattice as an operating system for defense, and Quantum Systems is putting fresh money into AI-powered autonomous systems too. Saronic is building autonomous vessels. The customer may be a defense ministry, but the pitch is still very familiar to anyone who has watched venture capital chase software margins.
Anduril is the company everyone circles back to because it has become the shorthand for the whole boom. The company raised $5 billion in May, doubling its valuation to $61 billion, according to reporting from Business Insider and the Financial Times. It was valued at just over $30 billion last year, so treating that older number as current undersells how fast the market has moved. Anduril also has something many defense startups still lack: large government contracts, including a reported 10-year, $20 billion U.S. Army deal tied to its Lattice command and control system.
That does not make every valuation sane.
Fortune reported that Anduril has traded at about 28 times its 2025 revenue, while older defense contractors such as Lockheed Martin and RTX trade at low single digit revenue multiples. Anduril CEO Brian Schimpf said "yes" at Fortune Brainstorm Tech in June when asked whether the sector is in a bubble. Trae Stephens, an Anduril cofounder and Founders Fund partner, has made the sharper point: there is too much venture supply chasing too few credible companies, and that can push early-stage defense startups to 17 to 50 times revenue before they have won a program of record.
That phrase matters. A program of record is not a demo day handshake. It is the difference between a government testing your system and a government building it into the budget. A startup with a signed multi-year Pentagon or NATO contract has revenue a lender can understand. One still working through pilots is betting on procurement machinery that can move painfully slowly, even when generals like the product. Shield AI, valued at $12.7 billion after announcing a March financing package, still carries plenty of work in that more uncertain zone.
Frankly, that is where the hype gets dangerous. Venture investors are good at valuing speed. Defense departments are good at moving slowly, asking for tests and changing requirements while purchasing decisions stretch across election cycles. The war in Ukraine has made drones and autonomy look urgent, and rightly so. It has also made every startup with a flying robot sound like a category winner before the contracts prove it.
For founders and investors, the lesson is not that defense tech is safe money. It is that governments have become the customer everyone wants because their budgets are large, sticky and politically protected. But a defense ministry is not a consumer subscriber. You do not win it with a slick onboarding flow and a better pricing page. You win it with performance, paperwork, relationships and patience.
That is why this funding rush is worth watching beyond the defense industry. AI capital is looking for customers with real budgets. Defense has them. Whether this year's valuations survive the next round of procurement reality is the question the bubble callers are actually asking.
