06/02/2026


Quantum computing firm Quantinuum has raised the size of its initial public offering (IPO) to $1.46 billion, boosting both the share quantity offered and the price range, Bloomberg and Reuters state, referencing the company's submission to the US Securities and Exchange Commission (SEC).



At first, Quantinuum intended to provide investors around 21 million shares, priced between $45 and $50 each. The firm is currently providing 26.5 million shares, priced between $53 and $55 each. According to Bloomberg estimates, Quantinuum's IPO market capitalization will reach $14.3 billion at the high end of the revised price range.

Bloomberg sources indicate that demand for Quantinuum's IPO surpassed the offering by over ten times. The firm intends to establish the IPO price on the night of Wednesday, June 3rd, with trading expected to commence on the 4th on the Nasdaq market using the ticker symbol QNT.

Quantinuum was established in 2021 after the combination of the quantum computing branches of Honeywell and Cambridge Quantum. It creates advanced quantum computers that can tackle intricate problems beyond the reach of conventional processors, for use in areas including chemistry, machine learning, cybersecurity, finance, and drug discovery. Despite Quantinuum's business being in the initial phases of commercial growth, Bloomberg observes that the company's order volume has increased considerably due to heightened interest in quantum technologies.
