(Sharecast News) - Quantinuum raised $1.68bn on Thursday after the quantum computing specialist debuted on Wall Street.

The company - which was founded in 2021 through the merger of Honeywell's quantum computing business with the UK's Cambridge Quantum - sold 28,000 shares at $60 each in the initial public offering, after both the price range and number of shares were upsized.

The IPO will likely value the Broomfield, Colorado-based business at more than $14bn.

Quantinuum, which employs around 700 people worldwide, posted a net loss of $192.6m on revenues of $30.9m in 2025, while cash burn was about $160m.

In the listing prospectus, Quantinuum said its mission was to "accelerate quantum computing and use its power to positively transform the world".

Chief executive Rajeeb Hazra told prospective investors: "I'm excited to share the progress we have made over the last decade towards achieving one of the most profound technology ambitions of our time: harnessing the laws of quantum mechanics to create a new computing paradigm - quantum computing - capable of solving problems fundamentally beyond the capabilities of classical computing.

"We have created a full-stack quantum computing platform with application software that is an industry leader in performance and accuracy, and we are already helping customers address real-world business and scientific challenges."

He added that quantum computing had the potential to "be as impactful as AI promises to be, if not greater".

Proceeds from the IPO will be used to further fund the company's growth.
