Key Takeaways
- • European defense startups are forecast to raise a record $10.5 billion in 2026, roughly four times the $2.6 billion raised in 2025, according to Dealroom's State of Defence Tech report published in October 2026.
- • As of September 20, 2026, European defense startups had already raised $7.4 billion, with mega rounds (each exceeding $1 billion) accounting for more than 85% of venture capital deployed; Germany's Helsing raised $1.8 billion in its Series E round alone in July.
- • The European Union's share of global defense-tech venture funding reached 21% by September 2026, up from 15% a year earlier, while the U.S. share fell to 75%—its lowest on record—reflecting a doubling of EU 27 funding year-over-year.
- • Drone and autonomous systems technology dominated European defense investment, capturing 74% of EU funding and 77% of UK funding, compared to 57% in the United States.
- • Across all NATO and allied countries, defense startups raised $27.1 billion in venture capital through September 2026, already exceeding the full-year 2025 total of $14.5 billion, with year-end projections reaching $38.5 billion.
Summary
European defense technology startups are on track for a record-breaking funding year in 2026, with Dealroom forecasting a full-year total of $10.5 billion in venture capital—a four-fold increase from the $2.6 billion raised in 2025. As of mid-September, European defense startups had already secured $7.4 billion, demonstrating the accelerating pace of capital deployment in the sector. This surge reflects growing geopolitical tensions and increased European investment in domestic defense capabilities following Russia's continued aggression in Ukraine and broader NATO strategic realignment.
The funding environment is being shaped by a handful of transformational mega-rounds, which represent over 85% of all venture capital invested in European defense startups this year. German startups have emerged as the dominant force, with Helsing's $1.8 billion Series E round in July exemplifying the scale of capital being deployed. Dealroom notes that German companies have set every major fundraising record in European defense-tech venture capital since 2023, underscoring Germany's position as the regional innovation hub for advanced defense technologies.
Europe's growing share of global defense-tech venture funding reflects a structural shift in capital allocation away from the United States. The EU accounted for 21% of defense startup funding through September 2026, up from 15% a year earlier, while the U.S. share declined to 75%—its lowest level on record. Dealroom characterizes this as "Europe catching up rather than the U.S. slowing," with EU 27 funding more than doubling year-over-year. Investment focus is concentrated in drone and autonomous systems technology, which captured 74% of EU funding and 77% of UK investment, significantly outpacing the 57% allocation in the United States.
The surge extends beyond Europe's borders. Across all NATO and allied countries combined, defense startups raised $27.1 billion through September 2026, already exceeding the total $14.5 billion raised during the entire 2025 calendar year. Dealroom projects that global NATO-allied defense startup funding will reach $38.5 billion by December 31, 2026, signaling a sustained acceleration in venture capital commitments to military and security technologies.
