Total European venture capital investment rose 5% to €66bn in 2025, a post-pandemic high, according to PitchBook. Those gains were driven by big deals for the continent’s top AI and defence companies. Last year, AI-related deals accounted for more than 35% of all European venture capital transactions, worth €23.5bn. That marked an increase from €17.7bn for such deals in 2024.
