The offering could value the company at over $20 billion and raise approximately $1 billion, marking a major milestone for the emerging quantum computing industry.\n\nQuantinuum was formed in 2021 through the merger of Honeywell Quantum Solutions and Cambridge Quantum. Honeywell holds a 54% stake, with IBM among other investors. In September 2025, the company raised $600 million at a $10 billion valuation from investors including NVIDIA's venture arm, JPMorgan Chase, and Mitsui.\n\nThe company develops trapped-ion quantum computers and employs over 630 people, including 370+ scientists and engineers across the US, UK, Germany, and Japan. In November 2025, Quantinuum launched Helios, a general-purpose quantum computer, and advanced to Stage B of DARPA's Quantum Benchmarking Initiative."}}
