What does the defense tech startup landscape look like today?
In our defense tech market deck, you will find everything you need to understand the market
SUMMARY
The defense tech startup landscape today is a large, fast-growing and increasingly industrial market, with the biggest value concentrating in a small group of companies that can turn new technology into military systems produced at scale.
The category itself has widened. Defense tech now includes not only drones and military software, but autonomous aircraft, missiles, maritime systems, factories, sensors and dual-use infrastructure when military demand is central to the business.
Funding is at record levels, but deal counts have not risen nearly as quickly as dollars invested. The market is already separating into hundreds of startups and a much smaller group of companies receiving billion-dollar rounds and institutional capital.
The biggest shift is from software alone toward full capabilities. Several of the best-funded startups now want to design the autonomy stack, build the vehicle or weapon, control manufacturing and expand into adjacent military markets rather than remain a specialist supplier.
Drones are still a huge market, but the basic airframe is becoming easier to commoditize. The more valuable layers are moving toward GPS-denied autonomy, coordination, electronic-warfare resilience, targeting, lower unit costs and the ability to manufacture at very high volume.
Military autonomy may become one of the strongest control points in the market because customers are beginning to separate the aircraft from the mission-autonomy software. If that architecture stays open, software companies could sell the same autonomy layer across several platforms instead of being tied to one vehicle.
Manufacturing capacity has become an investable defense technology in its own right. Hadrian, Saronic, Castelion, Mach Industries and Anduril are all putting large amounts of private capital into factories, shipyards or production networks because industrial capacity is now part of the military bottleneck.
Startups are finally winning meaningful production work, but prototype success still overstates commercial maturity. The DIU data is a useful reality check: roughly half of completed prototypes in the GAO review reached production, which leaves a large group of technically credible companies without scaled procurement.
Private valuations have moved faster than exits. Strategic acquisitions prove that scarce defense capabilities can sell for billions, but the market still has far more multi-billion-dollar private companies than large venture-backed IPOs or other liquidity events validating those prices.
The likely winners are the companies that can repeat three transitions: prototype to procurement, procurement to production, and one successful product into a broader platform. Defense demand looks durable; the harder question now is which startups can survive the capital, manufacturing and procurement burden of becoming a real defense prime.

How big is defense-tech startup funding right now?
Defense-tech startup funding is already running at record levels today, even under relatively narrow definitions of the market.
Crunchbase counted more than $14.6 billion invested in military, national-security and law-enforcement startups during roughly the first five months of 2026. Its equivalent total for all of 2025 was $9.6 billion. On that definition, the market broke its previous annual record before the year was half over.
PitchBook uses a broader definition. Financial Times analysis based on its data found around $12.3 billion of defense-tech venture investment during the first half of 2026, almost twice the level from the same period a year earlier and already above the previous full-year total in that dataset.
Those numbers look inconsistent at first, but the underlying message is the same. The exact size depends heavily on whether a company such as a satellite operator, advanced manufacturer or dual-use AI business counts as defense tech. Every serious dataset we found points in the same direction: private capital entering the sector has increased by several multiples from where it stood at the beginning of the decade.
Crunchbase, for example, recorded only about $1.6 billion of defense-related startup funding in 2020. On its current numbers, annualized investment is now running at roughly an order of magnitude above that level.
Defense tech has become a large venture category in its own right. The more difficult question is where all that money is actually going.
As this chart shows, and as featured in our defense tech market deck, search interest in defense tech has risen sharply
Why is defense tech growing so fast now?
Defense tech is growing so fast because military budgets, battlefield urgency and investor willingness to finance weapons companies have all moved in the same direction.
The customer budget is huge and still rising. SIPRI calculated global military expenditure at $2.887 trillion in 2025, 41% higher than a decade earlier after eleven consecutive years of growth.
Europe has changed particularly quickly. The European Defence Agency says EU member states spent €418 billion on defense in 2025, 20% more than the year before, and projects about €454 billion in 2026. Equipment procurement alone reached €115 billion in 2025. Defense R&D is expected to rise from €17 billion to around €20 billion.
NATO has raised the long-term ceiling further. Members have committed to spending 5% of GDP on defense and defense-related requirements by 2035, including at least 3.5% on core military needs. At the latest NATO summit, the alliance said total defense and security spending had already reached roughly 4% across members just one year into that ten-year effort.
That money is arriving while Ukraine, the Middle East and planning for a possible conflict in the Indo-Pacific are exposing shortages in missiles, interceptors, drones, ships and manufacturing capacity. Militaries are also seeing autonomous systems work under real combat conditions instead of simply watching demonstrations.
Investors now have both a much larger customer and a clearer list of things that customer urgently needs. That combination barely existed in defense venture investing ten years ago.
Is the defense-tech funding boom broad, or are a few startups taking most of the money?
Defense-tech funding is booming, but these days a surprisingly large share of the money is flowing into a small group of companies.
The clearest evidence comes from comparing deal count with dollars invested. Crunchbase counted 107 defense-related venture rounds by early June 2026 versus 206 during all of 2025. Funding, meanwhile, had already moved above the previous annual record. Deal activity had not doubled; check sizes had.
Several enormous rounds explain the difference. Anduril raised $5 billion at a $61 billion valuation. Shield AI announced $1.5 billion of new Series G equity plus $500 million of preferred financing at a $12.7 billion valuation. Saronic raised $1.75 billion at $9.25 billion. Quantum Systems raised $1.2 billion at roughly $8 billion. Helsing raised $1.8 billion at $18 billion. Hadrian then added another $1.37 billion financing at a $7.87 billion valuation.
Most recently, missile maker Castelion became another member of this group. Its latest Series C valued the company at $13 billion, with reporting from The Wall Street Journal putting the overall financing above $1 billion.
The investor base has changed alongside the check sizes. Blackstone, Goldman Sachs, JPMorganChase, Carlyle, Fidelity, Wellington, Apollo, T. Rowe Price, CPP Investments and other large institutions now appear alongside traditional venture firms.
So the boom is broad enough to create hundreds of startups, but the capital market is already picking a much smaller group of potential winners.

|---|---|---|---|
| Anduril | $5.0B | $61B | Multi-domain autonomous defense |

What are defense-tech investors actually funding today?
Defense-tech investors currently care most about autonomy, cheaper weapons, maritime systems, air defense and the factories needed to build all of them.
The biggest rounds make that unusually clear. Anduril, Helsing, Shield AI and Quantum Systems are all building around autonomous military systems. Saronic is applying a similar approach at sea. Castelion is targeting missiles. Hadrian is building manufacturing infrastructure. Mach Industries is combining unmanned weapons, propulsion and its own production network.
Government priorities line up with the private money. NATO's latest capability targets emphasize areas such as air and missile defense, long-range weapons and industrial production. European procurement initiatives prioritize missiles, ammunition, drones, counter-drone systems, electronic warfare, AI and other technologies where current inventories are clearly inadequate.
The interesting change is how much broader the startup ambition has become. Five years ago, a credible defense-tech pitch could be a better sensor or a better piece of battlefield software. Today, several of the best-funded companies want to deliver an entire military capability and manufacture it themselves.
We can see where the money is clustering:
| Defense-tech market | What investors are really betting on | Examples |
|---|---|---|
| Autonomous aircraft | Cheaper combat mass controlled by software | Anduril, Shield AI, Helsing |
| Maritime autonomy | Uncrewed surface and underwater fleets | Saronic |
| Missiles and strike | Faster development and much larger production | Castelion, Mach Industries |
| Counter-drone defense | Lower-cost ways to stop large drone attacks | Epirus, Helsing |
| Military software and AI | Faster sensing, targeting and command decisions | Anduril, Vannevar Labs |
| Defense manufacturing | More output from a constrained industrial base | Hadrian |
| Multi-domain autonomy | One software architecture across many vehicles | Quantum Systems, Anduril |
Are drones still the center of the defense-tech startup market?
Drones are still central to defense tech, but simply being a drone company is becoming less interesting.
Ukraine shows how quickly the hardware layer is filling up. Brave1 currently has around 2,500 companies and more than 5,000 products in its defense ecosystem. More than 500 companies make UAVs. Another 300-plus work on electronic warfare or signals intelligence, more than 200 make ground robots and roughly 200 develop AI products.
There is already large-scale purchasing behind those numbers. Ukraine's Ministry of Defence said more than 400 combat units had used the Brave1 Market system and ordered more than 500,000 drones through its combat-points program in less than a year, alongside ground robots, electronic-warfare systems and other equipment.
Once hundreds of manufacturers can produce airframes, the valuable problem moves elsewhere. Can the drone navigate without GPS? Can it identify targets? Can several drones coordinate? Can it survive electronic warfare? Can the manufacturer keep cutting cost? Can production scale from hundreds to tens of thousands?
That helps explain why the largest Western valuations are increasingly attached to autonomy stacks, integrated systems and manufacturing rather than basic drone hardware.
Drones remain one of the largest defense-tech markets. The easy version of the drone startup is getting crowded.

This chart, included in our defense tech market deck, shows why Anduril is winning in defense tech
Is autonomy becoming the real prize in military aviation?
Military autonomy is becoming one of the most valuable layers in defense tech because the U.S. Air Force is starting to buy aircraft and their AI control software separately.
The Collaborative Combat Aircraft program gives us unusually concrete evidence. The Air Force has awarded production contracts to General Atomics for the FQ-42 and Anduril for the FQ-44, with at least 150 aircraft planned across the first increment by the end of the decade.
At the same time, the Air Force created a separate competitive market for mission-autonomy software. Six companies sit in the supplier pool, while Anduril, Shield AI and RTX's Collins Aerospace received the first production options.
That architecture is important. An autonomous aircraft now has several software layers. Basic flight autonomy keeps the aircraft safely flying. Mission autonomy decides how it executes tasks alongside other aircraft and human pilots. The Air Force is deliberately trying to avoid tying that second layer permanently to one airframe manufacturer.
Recent tests show that this idea is moving beyond simulation. Shield AI's Hivemind and Collins' Sidekick have flown on CCA aircraft, while Anduril has demonstrated different autonomy systems on its FQ-44 platform. The Air Force has also put operational personnel, rather than only test engineers, in charge of launching, recovering and tasking the FQ-44 during exercises.
If militaries keep this open architecture, a company that controls a strong autonomy layer could sell it across several aircraft and eventually across several domains. That is a much more scalable position than building one drone.
We still do not know how open the architecture will remain once weapons employment, safety certification and classified mission systems become more complicated. But the market is already behaving as if autonomy could become one of the most important control points in future military systems.
Are missiles and air defense becoming the next big defense-tech market?
Missiles and air defense are now among the strongest defense-tech startup opportunities because Western militaries need far more weapons and much cheaper ways to stop incoming ones.
Castelion is the clearest recent example. The company has reached a $13 billion valuation only a few years after being founded by former SpaceX engineers. Its latest financing is being used to expand Blackbeard hypersonic missile production, develop longer-range weapons and work on a mass-produced air-defense missile. The company has already invested around $250 million in a New Mexico production site and is planning additional capacity.
The economic problem behind that funding is easy to understand. Large inventories of sophisticated missiles take years to replenish, while current wars are consuming them at rates that peacetime industrial systems were never designed to support.
The defensive side has the same problem. A cheap attacking drone can force the defender to fire an interceptor costing many times more. Epirus is attacking that cost imbalance with Leonidas, a high-power microwave system designed to disable drones electronically. The company has raised hundreds of millions of dollars and won U.S. Army work after demonstrating the system against drone swarms.
We are also seeing new companies formed specifically around this problem. New entrants are combining Ukrainian drone and autonomy experience with Western financing to build cheaper layered air-defense systems for military bases and critical infrastructure.
The strongest opportunity is straightforward: make sophisticated weapons much faster and cheaper, or make the cost of stopping cheap weapons dramatically lower.

Why are investors suddenly funding defense factories?
Defense manufacturing has become a venture market because production capacity itself is now a strategic bottleneck.
Hadrian shows how far this idea has gone. The company recently raised $1.37 billion at a valuation just under $8 billion. It now operates several automated manufacturing sites and has expanded into work supporting submarine and other defense production. Investors are effectively valuing Hadrian as technology infrastructure for the defense industrial base rather than as a conventional machine shop.
Weapons startups are reaching the same conclusion internally. Saronic plans a roughly $3.2 billion shipyard in Texas that could eventually employ thousands of people. Mach Industries has been building its Forge manufacturing network and bought propulsion company Exquadrum. Castelion has already put hundreds of millions of dollars into missile-production capacity.
Anduril has taken vertical integration furthest. Its Arsenal-1 factory in Ohio is designed around much higher-volume autonomous-systems production than traditional aerospace plants. The first Arsenal-1-built FQ-44 has now rolled off that line, only weeks after the Air Force formally moved the aircraft into production.
For years, the popular defense-tech idea was that Silicon Valley could improve the military by writing better software. The current market is making a much bigger bet: venture-backed companies can redesign the factories, supply chains and production methods behind the weapons as well.
That requires far more capital, but the potential market is also far larger.
Are defense startups finally winning real military production contracts?
Defense startups are crossing the line from prototype contracts into real production programs, although that transition is still where many companies fail.
The FQ-44 is the cleanest example. The U.S. Air Force awarded Anduril an engineering, manufacturing and production contract for its Collaborative Combat Aircraft alongside General Atomics. The program moved into production four months earlier than originally planned, and the Air Force expects at least 150 FQ-42 and FQ-44 aircraft across the first increment.
Anduril has also won a Marine Corps counter-drone contract with a ceiling above $600 million. Vannevar Labs moved a Defense Innovation Unit prototype into a production agreement worth up to $99 million. Epirus has received U.S. Army production-related work for its counter-drone technology.
The aggregate numbers still force us to be selective. A GAO review found that the Defense Innovation Unit awarded 450 prototype agreements between fiscal 2016 and 2023. Among projects with completed prototypes, 51% transitioned to production. DIU reported 62 production transitions with combined contract ceilings above $5.5 billion.
A startup announcing a Pentagon pilot has cleared only part of the journey. A production contract carries much more weight.
| Company or program | What has moved beyond experimentation | Why we care |
|---|---|---|
| Anduril FQ-44 | Air Force production contract | Venture-backed company entered combat-aircraft production |
| Anduril counter-UAS | Marine Corps contract ceiling above $600M | Creates deployment and sustainment revenue |
| Vannevar Labs | DIU production agreement up to $99M | Military software moved beyond prototype stage |
| Epirus | U.S. Army counter-drone contracts | New directed-energy approach entered procurement |
| DIU portfolio | 51% transition rate among completed prototypes | Shows both the opportunity and the failure rate |

Can defense startups really take business from Lockheed Martin, RTX and Northrop Grumman?
Defense startups can now take important programs from traditional primes, but the strongest newcomers are more likely to join the top tier of defense contractors than wipe out the old one.
The Collaborative Combat Aircraft competition gives us a clean test. Anduril won one of the two initial production positions. Lockheed Martin and Northrop Grumman had competed earlier in the program but did not win those airframe production slots. On mission autonomy, meanwhile, Anduril and Shield AI advanced alongside Collins Aerospace, while several incumbent contractors remain in the wider competitive pool.
That is real disruption. A venture-backed company founded in 2017 is now manufacturing a new U.S. combat aircraft while some of the largest aerospace companies in the world watch from outside that particular production award.
The incumbents still control enormous advantages. Nuclear weapons, ballistic-missile submarines, strategic bombers, fighter fleets, large radar networks and many classified systems involve engineering, certification, sustainment and government relationships built over decades. Lockheed Martin alone generates tens of billions of dollars of annual defense revenue.
The relationship is also becoming more collaborative. Airbus co-led Quantum Systems' latest financing. Major defense groups are investing record amounts into startups. Lockheed Martin recently agreed to pay $3.45 billion for Ultra Maritime, while Thales moved to acquire control of undersea-robotics specialist Exail at a multi-billion-euro valuation.
We expect more competition around new programs and more acquisitions around technologies the primes do not want to build from scratch.
The startup opportunity is already large without assuming that Lockheed Martin disappears.

Is Europe finally producing serious defense-tech startups?
Europe now has several defense-tech startups with enough capital, revenue and government demand to become major defense companies, although the U.S. ecosystem remains much deeper.
Helsing has become the clearest European example. Its latest $1.8 billion Series E valued the company at $18 billion. The company has expanded from battlefield AI into physical systems and has won large European government contracts, including work around drones and military combat-cloud software.
Quantum Systems has followed quickly. Its $1.2 billion Series D valued the German company at roughly $8 billion. Management says the company is profitable, and it is expanding from aerial drones toward a broader family of autonomous systems connected through its Mosaic software platform. Airbus, Blackstone and Advent were among the investors leading the round.
The underlying European customer is getting much larger. EU defense expenditure rose to €418 billion in 2025 and is projected around €454 billion in 2026. Equipment procurement alone reached €115 billion. NATO members are simultaneously working toward much higher long-term spending commitments.
Europe still has one major handicap: a startup can face different procurement systems, military requirements, export politics and industrial preferences across individual countries. A U.S. company can build around one enormous federal defense customer before expanding internationally.
Capital is becoming less of an excuse, though. Helsing and Quantum Systems together raised about $3 billion in their latest rounds. European founders can now finance companies at a scale that would have looked unrealistic only a few years ago.
The next test is whether Europe can turn those heavily funded companies into repeat suppliers across several national militaries rather than national champions with impressive valuations.
This chart, featured in our defense tech market deck, shows the share of revenue generated by each customer segment in the defense tech market
Is Ukraine still the fastest defense-tech market to learn from?
Ukraine remains the most intense real-world testing environment for defense startups today because technology can move from a workshop to combat faster there than in normal Western procurement systems.
Brave1's current ecosystem contains about 2,500 companies and more than 5,000 defense products. Those companies cover drones, ground robots, electronic warfare, missiles, naval systems and AI. Brave1 and the Ukrainian military have also identified dozens of specific technology priorities based directly on what frontline units need.
The buying system is unusually interesting. Ukrainian combat units can earn points from battlefield activity and spend them through Brave1 Market on equipment they choose themselves. More than 500,000 drones have already been ordered through that mechanism, with hundreds of units participating and more than 800 products available on the marketplace.
That creates a feedback loop that most startups selling to NATO militaries can only dream about. Units use a product, discover what fails under electronic warfare or enemy adaptation, communicate the problem and move toward another version quickly.
The latest battlefield evidence also shows why the learning never stops. Ukraine is expanding the use of unmanned ground vehicles for logistics and casualty evacuation because continuous drone surveillance makes ordinary supply movements dangerous. More than 22,000 UGVs have reportedly been contracted this year, while the government has set a much larger production target.
Ukraine also teaches a harder lesson: today's breakthrough can become ordinary very quickly. With hundreds of suppliers competing and adversaries constantly changing countermeasures, technological advantages decay fast.
Are defense-tech valuations already too high?
Some defense-tech startup valuations look extremely aggressive, especially where investors are pricing companies years ahead of their proven revenue.
Anduril gives us the most useful benchmark because we have a real revenue number. The company said 2025 revenue more than doubled to about $2.2 billion. Its latest completed $61 billion financing valuation therefore came to roughly 28 times trailing revenue.
That multiple already assumes a great deal of future success. Anduril would need to grow into a genuinely large defense prime for today's valuation to look ordinary on mature defense-company economics.
Helsing looks even more stretched on current revenue. Financial Times analysis around its latest financing put its $18 billion valuation at roughly 32 times projected 2026 revenue. The same analysis estimated materially lower multiples for some peers.
Mach Industries offers another example of how quickly pricing can move. Its valuation jumped from roughly $470 million to $1.8 billion in about a year.
There is a rational explanation for part of this. A defense company can win a platform or weapon program that produces revenue for decades. The market is trying to price that possibility before the full contract base exists.
But we should be careful with the numbers defense companies announce. A $500 million contract ceiling does not mean $500 million will definitely be spent. A prototype agreement is not recurring revenue. A planned factory is not production. A military program can also be delayed or cancelled after years of work.
Anduril has now removed some of that uncertainty by reaching real FQ-44 production. Even so, its valuation and those of several peers imply that investors already expect today's leaders to become tomorrow's major primes.
We think that is plausible for a handful of companies and mathematically impossible for all of them.

Are defense-tech exits catching up with these private valuations?
Defense-tech exits are improving, but there still are not enough large exits to validate the number of multi-billion-dollar private companies being created.
AeroVironment's acquisition of BlueHalo gives us one strong example. The transaction closed with roughly $3.5 billion of net merger consideration and created a larger defense-technology group spanning autonomous systems, space, cyber and directed-energy capabilities.
The more recent maritime deals are even more striking. Lockheed Martin agreed to acquire Ultra Maritime for $3.45 billion. Thales moved to take control of Exail Technologies at an enterprise valuation around €3.9 billion. Fincantieri has also been investing across maritime-drone and undersea businesses.
Those transactions show that strategic buyers are willing to spend billions when a company owns scarce technology in a priority domain.
Startups are also starting to buy other companies themselves. Shield AI used part of its latest financing to acquire military-simulation company Aechelon, which gives it more infrastructure for training and testing autonomous aircraft.
The missing piece remains the public market. Private defense valuations have risen much faster than the number of venture-backed defense companies completing major IPOs. M&A can return plenty of capital, but a sector producing companies valued at $8 billion, $13 billion, $18 billion or $61 billion eventually needs several very large liquidity events.
Until those arrive, defense tech has proven its financing model more convincingly than its exit model.
Which defense-tech startups look most vulnerable now?
The defense-tech startups most exposed today are companies stuck between a good prototype and a product that militaries repeatedly buy at scale.
We can already identify several pressure points.
Commodity drone makers face brutal competition. Brave1 alone tracks more than 500 UAV manufacturers in Ukraine. A company whose main advantage is an airframe will struggle as components become cheaper and militaries demand better autonomy, electronic-warfare resistance and unit economics.
Pilot-heavy companies have another problem. The GAO's review of DIU showed that only about half of completed prototypes transitioned into production. Winning an innovation contract may establish technical credibility without creating a durable business.
Capital-intensive manufacturers face the opposite danger. A missile, aircraft or shipbuilding startup can consume hundreds of millions of dollars building capacity before government demand becomes predictable. If a major program slips, factory utilization can collapse.
Highly valued companies also have less room for mistakes. A startup worth a few hundred million dollars can survive a failed program and redirect itself. A company valued at $10 billion or $20 billion needs several large wins to support the expectations already built into its price.
The companies we would watch most closely are those with high valuations, narrow customer concentration, large planned factories and limited evidence of repeat procurement.
The next shakeout will probably be driven by execution rather than technology.
In our defense tech market deck, we identify pain points entrepreneurs should prioritize
Are we actually getting a new generation of defense primes?
A small group of defense-tech startups are now starting to look like genuine next-generation defense primes rather than specialist technology suppliers.
Anduril is furthest along. It combines a common software architecture with sensors, counter-drone systems, underwater vehicles and autonomous aircraft, while building its own manufacturing infrastructure. The FQ-44 has already moved into U.S. Air Force production and the first Arsenal-1-built aircraft has rolled off the line.
Helsing is following a comparable path in Europe. The company has moved beyond defense AI into autonomous weapons and physical platforms while raising enough capital to finance much larger industrial programs.
Quantum Systems now explicitly talks about becoming a multi-domain company across air, land and sea. Saronic is building autonomous vessels and planning a large shipyard. Castelion is developing several missile families while investing directly in production capacity.
There is a common pattern here. These companies raise private money before government demand is fully guaranteed, develop hardware and software together, manufacture more of the product themselves and then expand from one successful capability into adjacent military markets.
That model could create several large new defense companies.
It will also separate the strongest startups from the rest of the sector. Selling one clever component can create a valuable supplier. Becoming a prime requires product breadth, manufacturing, long-term contracts, integration capability and enough capital to survive programs that take years.
For now, perhaps five to ten private companies globally look genuinely capable of attempting that jump. Thousands of defense startups do not.
If you want more recent data on this point, please see our latest defense tech market report.
What does the defense tech startup landscape look like today?
The defense tech startup landscape today is genuinely strong and increasingly industrial, but the biggest opportunity is concentrating around a relatively small group of companies that can turn new technology into weapons produced at scale.
We have enough evidence now to move beyond the idea that defense tech is simply enjoying a venture-capital fashion cycle. Global military expenditure is close to $2.9 trillion. European budgets are rising by tens of billions of euros a year. NATO members have committed to a much larger long-term spending base. Ukraine has created a battlefield innovation ecosystem with thousands of companies. Western militaries are explicitly prioritizing autonomous systems, missiles, air defense, drones and production capacity.
The commercial evidence has become stronger too. Startups are raising billion-dollar rounds from mainstream institutional investors. Autonomous combat aircraft have moved into production. Missile companies are building factories before traditional procurement timelines would normally allow it. Defense manufacturing itself has become venture-backed. Large incumbents are buying modern defense businesses for several billion dollars.
We should still resist treating every defense startup as a winner. Capital is heavily concentrated. Several private valuations assume extraordinary future growth. Roughly half of completed DIU prototypes in the GAO dataset reached production, which also means roughly half did not. Hardware companies can burn huge amounts of money before reaching scale, and the exit market remains less developed than the financing market.
The biggest shift is happening at the top of the sector. Companies such as Anduril, Helsing, Shield AI, Quantum Systems, Saronic, Castelion and Hadrian are being financed to solve much larger problems than the previous generation of defense startups. They are building aircraft, missiles, autonomous fleets, software platforms, factories and supply chains.
That changes our final judgment. Defense tech has already become a major startup market, and current government spending makes a collapse in underlying demand unlikely. The harder phase starts now.
The companies that dominate the next decade will be the ones that can repeatedly cross the gap from prototype to procurement, from procurement to production and from one successful product into a broader defense platform. Most startups will never get through all three steps. The few that do could become some of the largest new industrial companies created this decade.

OUR METHODOLOGY
The defense-tech market is moving quickly, and no single funding number, company or battlefield example is enough to describe the startup landscape. We broke the question into capital flows, government demand, procurement and production, technology priorities, battlefield adoption, industrial capacity, competitive dynamics, valuations and exits.
We prioritized recent evidence because the market is changing too quickly for older averages to carry the analysis on their own. That includes newly announced financing rounds, government spending and capability commitments, production contracts, procurement data, factory investments, battlefield adoption and acquisitions.
We did not treat large announcements as conclusions by themselves. A funding round shows investor conviction, a prototype contract shows technical interest and a factory announcement shows ambition, but we gave more weight to evidence of repeat procurement, production, scaled deployment and industrial execution.
Where datasets use different definitions of defense tech, we compare them instead of forcing them into one total. The boundary is especially messy around space, advanced manufacturing, cybersecurity, AI and other dual-use technologies, so we use multiple datasets to check whether the same underlying pattern still appears.
We also separate momentum from execution. Capital raised, valuations and announced programs help show where the market is moving, but production contracts, procurement transitions and actual military deployment carry more weight when judging how mature a company or segment has become.
Key market and government sources include SIPRI on global military expenditure, the European Defence Agency on EU defense spending, NATO on the 5% defense-investment commitment, NATO on the 2026 Ankara Summit, NATO on deterrence and capability priorities, and Crunchbase on defense-tech funding.
For company financing and strategy, we used direct or first-hand sources including Anduril on its $5 billion Series H, Shield AI on its $2 billion financing and Aechelon acquisition, Helsing on its $1.8 billion Series E, Quantum Systems on its $1.2 billion Series D, Saronic on its $1.75 billion Series D, Castelion on its $1 billion Series C, and Mach Industries on its $300 million Series C.
For procurement, production and battlefield adoption, the main sources were the U.S. Air Force on Collaborative Combat Aircraft production, the Defense Innovation Unit on Vannevar Labs moving to production, the U.S. Government Accountability Office on DIU prototype-to-production performance, Brave1 on the Ukrainian defense-tech ecosystem, and Ukraine's Ministry of Defence on more than 500,000 drones ordered through Brave1 Market.
The final judgment comes from looking for convergence across those categories rather than relying on a proprietary score or one preferred dataset. Funding, government budgets, procurement, battlefield demand, production, industrial investment and company behavior all point toward a much larger defense-tech market, while valuations, prototype conversion and exits show where the risks are still concentrated.
