Quantinuum IPO oversubscribed: Offering price raised by 10%, valuation hits $14 billion, listing on 6/4

Quantum computing leader Quantinuum's Nasdaq IPO subscription has reached "double-digit multiple" oversubscription. The company is considering simultaneously increasing the share issuance and raising the price range by approximately 10%. The originally planned $12.7 billion valuation could be pushed above $14 billion, with listing expected on 6/4 under the ticker QNT, making it the world's first full-stack quantum computing company to go the traditional IPO route.

This company, formed from the merger of Honeywell's quantum computing division and Cambridge Quantum, was valued at $5 billion when raising $300 million in January 2024, then doubled to $10 billion when raising another $600 million in September 2025, with Quanta Computer and NVIDIA's NVentures both participating in that round. Now investors are scrambling to get in at higher prices. Bloomberg cited sources familiar with the matter on the 29th saying the company is considering simultaneously increasing the issuance size and raising the pricing range by approximately 10%. Previous reports indicated the IPO received multiple-times oversubscription, and sources further revealed the subscription multiple has reached "double digits," with investor demand far exceeding expectations. Luxurious Underwriting Lineup Quantinuum originally planned to issue approximately 21 million shares with a pricing range of $45 to $50 per share, giving a fully diluted valuation of approximately $12.7 billion. If the price range is raised by 10%, the new range would fall between $49.50 and $55, with valuation potentially reaching $14 billion. Lead underwriters are headed by JPMorgan, Morgan Stanley, and Goldman Sachs, with co-underwriters including Bank of America, UBS, Jefferies, Evercore ISI, and more than a dozen others. The company expects to complete pricing on 6/3 and list on Nasdaq under the ticker "QNT" on 6/4. This is the world's first full-stack quantum computing company to go public through a traditional IPO. Previously, peers IonQ, D-Wave, and Rigetti all took the SPAC shortcut to listing. Quantinuum chose to face underwriting scrutiny head-on. Besides Honeywell (holding 49.1% post-IPO) as the parent company's trump card, there is also the Trump administration's announced $2 billion quantum investment plan, from which Quantinuum is expected to receive approximately $100 million and hand over a minority stake, effectively securing national endorsement before the IPO. Book Losses, Investors Look at the Roadmap Quantinuum's books don't look great. Full-year 2025 revenue was only $30.9 million, with a net loss of $192 million and cumulative losses of approximately $1.5 billion, and about 60% of revenue came from a single customer, Japan's RIKEN. The main draw is its global technological leadership. Quantinuum's trapped-ion route will go commercial in 2026 with the Helios system, equipped with 98 fully-connected physical qubits, 48 logical qubits, and two-qubit gate fidelity of 99.921%. Early customers include Amgen, BMW, JPMorgan, and SoftBank. The next stop on the roadmap, Apollo (expected 2029), targets a fully fault-tolerant universal quantum computer with million-gate circuits. For peer comparison, already-listed IonQ has a market cap of approximately $19.4 billion and 2025 revenue of $100.5 million, making it the first in the quantum industry to break $100 million. Quantinuum's revenue is only one-third of IonQ's, but its IPO valuation is already close to 70%. Quantum computing IPOs over the past three years have all gone the SPAC route, and the market has long been skeptical about pricing power for such companies. That Quantinuum can take the regular route and still see off-the-charts subscription shows institutions are repricing the entire sector. FAQ What are the terms of the Quantinuum IPO? Originally planned to issue 21 million shares priced at $45-50/share, Nasdaq ticker QNT, listing as early as 6/4. Due to "double-digit multiple" oversubscription, considering raising the price range by approximately 10% to $49.50-$55. How is Quantinuum different from already-listed quantum computing companies? Quantinuum is the first full-stack quantum computing company to take the traditional IPO route. Previously, IonQ, D-Wave, and Rigetti all listed via SPAC. IonQ's 2025 revenue of $100.5 million leads the industry, while Quantinuum's revenue of $30.9 million but IPO valuation of $12.7 billion is already close to IonQ's $19.4 billion market cap.
