Amazon.com IncEuropean tech investment in the second quarter of 2026 saw capital infrastructure become more visible around strategic sectors, according to Zubr Capital's latest digest. Beyond large equity rounds, support increasingly came through growth capital vehicles, public equity channels, guarantees, and credit facilities, with EIFO committing €200 million to the Scaleup Europe Fund and the British Business Bank recording over €695 million in direct equity activity in British science and tech scaleups. Hybrid capital also played a larger role, as Nscale secured an additional €670 million for AI data centre infrastructure in Norway, ICEYE obtained a €300 million revolving credit facility, and InSoil closed a €120 million senior secured credit facility backed by an EIF guarantee. DefenceTech matured further, with Germany's Quantum Systems commanding a €1 billion Series D, the planned €500 million E2D growth fund targeting dual-use scaling gaps, and the EIF Defence Equity Facility 2.0 setting an initial €1 billion target. Quantum computing emerged as a distinct investment cluster, highlighted by Oxford Quantum Circuits' €301 million round, IQM Quantum Computers' €275 million Series B, and QuantWare's €152 million raise. The UK maintained its lead with large rounds and fund closes such as Mouro Capital Fund III's €343.7 million first close, while Central and Eastern Europe showed signs of moving beyond small experiments, with Viktor closing a €64.7 million Series A and EIF and Poland's BGK committing €85 million to three Polish venture funds focused on defence, frontier technology, and AI. Direct US strategic capital also moved into European scaleups, with NEURA Robotics' up to €1.2 billion Series C including Tether, Qualcomm, Amazon, and NVIDIA, and QuantWare's round featuring Intel Capital and In-Q-Tel.
