OQC raises £260m in Europe’s largest ever private quantum computing funding round

London, UK — 3 June 2026 – OQC today announced it has closed an oversubscribed £260 million ($350m) Series C funding round, Europe’s largest ever private funding round for a quantum computing company. The investment establishes OQC as one of the world’s best-capitalised private quantum computing companies, enabling the expansion of its deployed systems in key markets. It reflects growing confidence in the commercialisation of quantum technologies, and the UK’s ability to scale globally competitive deep tech companies.

Bullhound Capital led the round, which included investment from the British Business Bank, Fynveur (advised by Invus), COFIDES, RCM Private Markets Fund managed by Rokos Capital Management (US) LP, Alpha Edison, Fulcrum Asset Management, Pentland Ventures, Magdalen College Oxford, Adaptive Capital Partners, Firgun Ventures, 18 West and Oxford Capital. Existing investors including Oxford Science Enterprises, SBI, Chevron Technology Ventures, The University of Tokyo Edge Capital Partners Co. and OTIF Ventures also participated, reflecting continued support for OQC’s technology roadmap and international expansion. J.P. Morgan acted as exclusive placement agent on the transaction.

Founded in the UK, OQC develops and operates superconducting quantum computers designed for deployment in data-centre environments serving enterprise and government customers. The company has established a global quantum computing platform across Europe, North America and Asia, with systems deployed in the UK, US, Japan and Spain.

Enterprise and government customers across financial services, defence and security are driving demand for OQC’s systems as they seek secure, scalable quantum infrastructure to tackle problems beyond the practical reach of classical computing. The funding will be used to expand OQC’s operational presence in priority markets and accelerate its roadmap toward commercially useful, fault-tolerant quantum computing.
