On June 4, Quantinuum rose 12.75% in regular trading on its first day as a public company, trading at $67.13/share with trading volume of $527 million. The stock debuted well above its IPO price of $60 per share.

The surge follows Quantinuum's blockbuster IPO, which priced at $60 per share — significantly above the already-raised range of $53 to $55. The company sold 28 million shares, raising $1.68 billion and valuing the firm at approximately $15 billion. The offering was more than 20 times oversubscribed, with strong demand from long-only institutional investors prompting multiple upward revisions from the original range of $45 to $50.

Quantinuum, a quantum computing company spun out of Honeywell in 2021, focuses on trapped-ion quantum computing technology. Honeywell retains approximately 48.1% combined voting power post-IPO. The company received a $100 million commitment from the U.S. government's $2 billion quantum computing support program. Analysts noted that Quantinuum's traditional IPO path — rather than the SPAC route taken by other quantum firms — and its scarcity value in the public quantum computing space contributed to robust investor appetite.
