Venture capital investment in defence technology has accelerated sharply in 2026, with global funding reaching $12.3bn so far this year as conflicts in Ukraine and the Gulf drive renewed demand for next-generation military systems, according top a report by the Financial Times.
The figure already exceeds the total recorded for the whole of the previous year, according to market data, highlighting the speed at which defence-related start-ups are attracting capital as investors reposition for a more sustained cycle of global military spending.
The boom has been led by large US-based funding rounds, including a major capital raise by Anduril Industries, which nearly doubled its valuation to $61bn following a $5bn financing round backed by major venture investors.
Other significant US players include autonomous systems developers such as Saronic Technologies and Shield AI, which are building uncrewed maritime and aerial defence platforms aimed at modernising battlefield capabilities.
The surge in investment reflects growing expectations that governments will continue to expand defence budgets in response to geopolitical instability, particularly as traditional warfare evolves toward lower-cost, high-technology systems.
However, the rapid pace of capital deployment has also raised concerns among investors that parts of the sector may be entering a valuation-driven hype phase, with some questioning whether current pricing levels fully reflect long-term revenue sustainability once conflict dynamics shift.
Despite those concerns, proponents argue that structural demand for defence innovation will persist beyond current conflicts, driven by the need for autonomous systems, surveillance infrastructure, and AI-enabled command capabilities.
European start-ups have also attracted increasing attention, though at a smaller scale compared with the US market. Companies such as Helsing and Stark are among those raising significant rounds as the region seeks to rebuild and modernise its defence industrial base.
Investors say capital is increasingly concentrated in subsectors such as drones, autonomous naval systems and space-based surveillance technologies, while valuations in certain segments have risen sharply as competition for high-growth assets intensifies.
Industry participants note that while enthusiasm remains strong, the sector is becoming more selective, with investors focusing on revenue visibility, government procurement pipelines and long-term strategic contracts rather than purely speculative growth narratives.
