The Defence Robotics Investment Guide: Navigating the $27.6 Billion Autonomous Systems Market

What happens when venture capital discovers that defence is no longer a compliance problem but a $49 billion market?

Until 2022, most top-tier venture firms treated defence as an ethical exclusion. Today, the same firms are raising dedicated defence-tech funds. The catalyst was not a policy change. It was Ukraine demonstrating that cheap autonomous systems can outperform billion-dollar platforms in real combat. The ROI argument won over the moral one.

What Is Accelerating

Three sub-segments are absorbing capital at an accelerating rate. Autonomous drones lead, but the mix is shifting.

Unmanned aerial systems (UAS) dominated deal flow in 2025 with $6.2 billion across 169 transactions, driven by combat validation in Ukraine and the Middle East. The effective range, low cost, and ability to scale of FPV drones and medium-altitude long-endurance platforms have made them the default first purchase for any military upgrading its reconnaissance and strike capabilities. As we wrote in July, Agility Robotics went public through a SPAC merger. That signals the public markets are beginning to absorb robotics companies that were venture-backed just two years ago.

Unmanned maritime systems raised $944 million, and autonomous ground vehicles secured $512 million. The ground vehicle number is deceptive: it excludes the $238 million Series C raised by Forterra, which builds modular robotic platforms for military logistics, and Bedrock Robotics' $270 million round for autonomous construction equipment with defence applications. The actual ground-vehicle funding is higher when dual-use companies are counted.

European venture firms are also joining the cycle. The UK Ministry of Defence previewed a new investment plan on June 29 that bets heavily on drones and hybrid warships designed to operate with unmanned systems. Germany's Quantum Systems raised €340 million across two tranches in 2025, tripling its valuation to €3 billion. France's Defence Innovation Fund deployed €200 million into early-stage dual-use startups. The old European aversion to defence investing is collapsing faster than most institutional investors expected.

What Is Decelerating

Not every robotics segment is riding the wave. Logistics and warehousing, historically the largest recipient of robotics VC, shed 28.5% of its deal value in 2025 compared to 2024. Autonomous mobile robots (AMRs) and automated guided vehicles (AGVs) fell to €1.2 billion across 81 deals.

The rotation tells you something. Warehousing robotics rode the e-commerce surge of 2020-2022, but the market matured faster than expected. Margins compressed as Chinese manufacturers entered the segment with lower-priced units. Investors who once treated AMRs as a sure bet are now looking for higher barriers to entry. Defence procurement provides exactly that.

"Warehousing and logistics has moved out of the hype phase and into a tougher environment where investors want clearer differentiation, better margins and proof that these companies are not just selling into a slower industrial CapEx cycle," said Ali Javaheri, senior emerging spaces research analyst at PitchBook.

What Is Emerging

The dual-use model is the most important structural shift in defence robotics investing. Startups that can generate revenue from both government contracts and commercial customers de-risk their investment thesis and strengthen exit pathways.

A drone originally built for border surveillance is now being repurposed for critical infrastructure monitoring. An autonomous ground vehicle developed for logistics in conflict zones is being adapted for hazardous industrial environments. The addressable market doubles.

Si Robotics, a Polish startup founded in 2024, embodies this new model. The company builds dual-use humanoid robots for industrial and defence applications. It raised a pre-seed round from Sunfish Partners in 2025 and has 12 employees. Its CEO posts about "Physical AI" on LinkedIn with the explicit framing that "Europe needs to back real systems, not just demos" — a message that connects with both defence procurement officers and industrial automation buyers. A pre-seed humanoid robotics company with a dual-use thesis is exactly the kind of signal pre-seed investors track.

On the early-stage front, European pre-seed robotics companies are forming faster than any time in the last decade. FOV Ventures identified 10 pre-seed European robotics startups to watch in 2026, spanning mobility, manipulation, autonomy, and embodied AI — most still in stealth or first-pilot phase. These companies represent the next generation of defence-adjacent robotics platforms, and they are raising capital outside the traditional defence primes.

Comparison: The Defence Robotics Landscape

The market is consolidating around a small number of well-capitalized players, each occupying a distinct niche.

The table reveals a pattern: companies with a pure software or AI angle (Anduril, Helsing) command the highest valuations relative to capital raised. Hardware-heavy companies (Forterra, Mach) raise more capital per dollar of valuation, reflecting the capital intensity of physical production. The most capital-efficient plays in defence robotics are the software-defined autonomy platforms — not the vehicle manufacturers themselves.

The Consolidation Phase Has Begun

The 2025 funding record tells only half the story. The other half is about exits. Venture capital exits from defence-tech investments jumped to $54.4 billion in 2025 from $18.2 billion in 2024, a record driven almost entirely by acquisitions and not IPOs. The largest was Nvidia's €20 billion acquisition of Groq, whose AI hardware is used in military autonomous systems. That single deal returned more capital to defence-tech VC investors than all IPOs in the sector combined over the prior three years.

The exit wave is accelerating for a specific reason. Traditional defence prime contractors like Lockheed Martin, RTX, BAE Systems, and Rheinmetall are struggling to build AI-native software teams internally. Their procurement cycles were designed for hardware platforms with 20-year lifespans, not software that needs quarterly updates. Buying proven venture-backed startups is faster and cheaper than building the capability in-house.

"I would not be surprised to see a major venture-backed defence tech startup acquired by a traditional prime contractor in the first half of the year," Ali Javaheri of PitchBook told Defense News in January. By July, no such deal had been announced — but the pressure is building. Anduril at a $30.5 billion valuation is expensive even for Lockheed. The more likely targets are in the $1-5 billion range: Shield AI, Saronic, or a European player like Helsing.

For investors evaluating the space, the exit horizon matters. Defence tech exits are overwhelmingly strategic (acqui-hire and technology acquisition by primes) rather than financial (PE buyout or IPO). That means valuation multiples are capped by what primes will pay, not by what public markets will absorb. The ceiling is real, but the floor is higher than in any other robotics sub-sector because the buyers have strategic necessity on their side.

The next 12 months will test whether the 2025 funding surge translates into production volume. Manufacturing scale is "the next competitive battleground" in defence tech, according to Javaheri. The winners will be companies that can demonstrate not just a working prototype, but a production line that can deliver 100 units this year and 1,000 next year. That is a different skill set from raising venture capital — and it will separate the companies that become primes from those that become acquisition targets.
