Global investment in defence technology start-ups has hit a record $4.1 billion (£3 billion) this year, as the world's leading arms manufacturers significantly increase their spending on new military innovations. This unprecedented influx of capital underscores a growing international focus on next-generation defence capabilities.
Figures from Dealroom reveal that major defence contractors, including BAE Systems, Lockheed Martin, and Airbus, have been active participants in these venture capital funding rounds. Concurrently, separate research from White & Case indicates a substantial uptick in mergers and acquisitions within the defence sector, with 42 deals completed globally in the first half of 2026 – a 56 per cent increase from the same period last year. Experts suggest that strong demand for companies specialising in artificial intelligence (AI), cybersecurity, and autonomous systems is fuelling this surge, with these technologies increasingly redefining modern conflict.
Daniel Turgel, co-head of White & Case's Global Technology Industry Group, commented on the intensifying race to acquire and invest in defence technology. He highlighted that the world's largest defence companies are actively seeking to bolster their technological portfolios through both acquisitions and substantial funding rounds. Turgel anticipates that higher defence budgets globally and record levels of private capital will ensure investment and deal-making remain robust beyond the current year.
Recent weeks have seen several significant investments by defence manufacturers. Lockheed Martin, for instance, has pledged at least $100 million for UK and European defence technology start-ups and expanded its venture investment fund from $400 million to $1 billion. BAE Systems has committed €50 million to two European venture funds focused on defence, while Airbus has become the anchor investor in a new €500 million fund supporting dual-use technologies – technologies with both military and civilian applications.
The UK is also stepping up its defence spending and fostering domestic innovation. Last week, ministers awarded £708 million to BAE Systems and its Team Tempest partners to advance the Future Combat Air System programme. This initiative encompasses work on AI, robotics, digital engineering, and advanced manufacturing, supporting a vast supply chain of approximately 600 companies and academic institutions across the UK. Furthermore, the government is backing new defence businesses through the Technology and Growth Alliance, which aims to create 20 defence technology spin-outs annually by commercialising military research.
The economic implications for UK households and businesses are multifaceted. Increased defence spending and investment in cutting-edge technologies can stimulate job creation in high-skilled sectors such as engineering, AI development, and cybersecurity. For investors, this trend presents new opportunities beyond traditional defence manufacturers, with a growing focus on software, data, and autonomous systems. However, the Bank of England will be closely monitoring the broader economic impact of such significant government and private sector investment, particularly concerning its potential effects on inflation and interest rates.
