OQC has secured £260 million (US$350 million) in an oversubscribed Series C round, marking the largest private funding round ever completed by a European quantum computing company. The investment strengthens the UK-headquartered firm’s position as one of the world’s best-capitalised private quantum computing businesses and will support international expansion, additional system deployments and continued technology development.
The round was led by Bullhound Capital and included backing from the British Business Bank, Fynveur, COFIDES, Alpha Edison, Fulcrum Asset Management, Pentland Ventures, Magdalen College Oxford, Adaptive Capital Partners, Firgun, 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. J.P. Morgan served as exclusive placement agent.
Founded in the UK, OQC develops superconducting quantum computers designed for deployment in data-centre environments supporting enterprise and government users. The company has established a global platform spanning Europe, North America and Asia, with systems already deployed in the UK, US, Japan and Spain.
Demand is increasing from sectors including financial services, defence and security as organisations seek secure, scalable quantum infrastructure capable of addressing challenges beyond the reach of classical computing. The new funding will expand OQC’s presence in priority markets and accelerate progress toward commercially useful fault-tolerant quantum computing.
OQC CEO Gerald Mullally described the investment as a milestone for British quantum computing, highlighting growing confidence in the sector’s commercial potential and OQC’s ability to scale globally. The deal underscores Europe’s growing momentum in advanced technologies today.
