- Quantinuum raised $1.68 billion in an upsized US IPO, opened at $68 per share versus the $60 IPO price, surged as much as 19%, then closed at $60.38, giving the company a market value of about $16 billion.
- Investor demand for the offering exceeded 20 times the shares available, according to people familiar with the matter.
- Honeywell is expected to control 49% of voting power after the IPO, with Cambridge Quantum holding 33%, and Honeywell has indicated it will remain a strategic customer and partner.
- The quantum computing sector has rallied sharply in recent weeks — IonQ up more than 125%, D-Wave up more than 90%, and Rigetti up more than 70% from the end of March, while IBM gained nearly 40% over the past three weeks.
- The Trump administration announced more than $2 billion in quantum computing funding last month, with Quantinuum set to receive $100 million and IBM landing the largest award at $1 billion; the US government will take minority, non-controlling stakes in the companies.
- Quantinuum CEO Rajeeb Hazra framed the industry as a 'winner-takes-most market,' arguing the winner must deliver 'performance, accuracy, scalability and solutions.'
- JPMorgan Chase and Morgan Stanley led the offering, and the shares trade on the Nasdaq Global Market under the symbol QNT.
Why it matters: The $16 billion debut rewards Honeywell's 2021 bet on combining quantum hardware with Cambridge Quantum's software. The flat close shows investors wouldn't bid the stock above its IPO price, even with 20x oversubscribed demand and a broader sector rally — IonQ up 125%, D-Wave up 90% — plus $2 billion in Trump-administration funding.
