Quantinuum Hits $10B Valuation With $600M Raise

UK-based Quantinuum has raised $600 million, boosting its valuation to $10 billion. Controlled by Honeywell, the company attracted new investors Nvidia’s NVentures, Quanta Computer, and QED, joining its roster of global financial and strategic backers.

The funding supports rollout of the Helios quantum platform and research into fault-tolerant computing. Quantinuum’s partnership with Nvidia will expand through the Accelerated Quantum Research Centre, combining AI and quantum advances.

The company is expanding internationally with operations in Qatar, New Mexico, and Singapore, including a $1B state-backed quantum program in Qatar. With 630 staff, Quantinuum continues to scale as global interest in quantum accelerates.
