Honeywell's Quantinuum's IPO puts the quantum stock rally to the test Jared Blikre Tue, May 26, 2026 at 10:45 PM GMT+7 3 min read ^IXIC A Honeywell-backed (HON) company is aiming for one of the biggest public-market tests yet for the quantum computing trade.
Quantinuum is seeking to raise as much as $1.05 billion in its IPO, offering 21 million shares at $45 to $50 each. At the top of the range, Quantinuum would be valued around $12.7 billion and is expected to trade on Nasdaq (^IXIC) under the ticker QNT, according to IPO terms filed Tuesday.
That is a big ask for a company still in the early stages of commercializing quantum computing. Quantinuum was formed in 2021 through the combination of Honeywell Quantum Solutions and Cambridge Quantum, giving it both quantum hardware and software capabilities. The company says it is working toward a commercial-scale, fault-tolerant quantum computer before the end of the decade, with potential applications in chemistry, machine learning, cybersecurity, finance, and drug discovery.
