Quantinuum Raises $1.68 Billion in U.S. IPO at $60 a Share as Quantum Demand Surges
3 articles · Updated · Reuters · Jun 3
Summary
28 million shares priced at $60 each gave Honeywell-backed Quantinuum a $1.68 billion U.S. IPO, with Nasdaq trading set to begin Thursday under ticker QNT.
Strong demand drove the deal above expectations after Quantinuum earlier this week lifted its range to $53-$55 and increased the share count to 26.5 million.
Honeywell will retain about 48.1% of combined voting power after the offering, keeping significant control of the quantum-computing company formed in 2021 through its merger with Cambridge Quantum.
The listing is a key test for a thinly traded quantum sector that has seen rising bookings and fresh policy support, including the Trump administration's plan last month to take $2 billion of equity stakes in nine companies.
Analysts say Quantinuum's valuation and first-day trading could shape sentiment and pricing across listed quantum peers, even as the industry still faces high costs and uncertain commercial timelines.
As quantum IPOs soar, how close are these machines to actually solving real-world problems and generating real profit?
With the government now a direct investor, is the quantum computing boom a true tech revolution or the next speculative bubble?
Quantinuum’s Landmark $1.68 Billion IPO Signals Quantum Computing’s Coming of Age
Overview
Quantinuum made a major impact in the U.S. IPO market in June 2026, standing out during a busy period for new listings. The company attracted strong institutional demand and robust investor interest, reflecting both the growing excitement around quantum computing and the limited opportunities to invest in this advanced field. This enthusiasm led Quantinuum to upsize its offering, quickly increasing the number of shares and raising its valuation. The successful IPO highlights how investor confidence and market conditions combined to create a landmark moment for both Quantinuum and the broader quantum computing industry.
