Quantinuum Debuts on Nasdaq, Raising $1.68 Billion

Quantinuum, the trapped-ion quantum computing company formed from the 2021 merger of Honeywell Quantum Solutions and Cambridge Quantum Computing, begins trading on the Nasdaq Global Market under ticker 'QNT' after pricing an upsized IPO of 28 million shares at $60 each — above its $53–55 marketed range. The offering raised $1.68 billion, and shares opened at $68 before closing near the IPO price, valuing the company at roughly $15.7 billion. It is the first Nasdaq listing of a pure-play, full-stack quantum computing company (hardware, middleware, and software) at this scale, and CEO Raj Hazra called it a marker of the industry's shift from research labs toward commercial deployment.
