TL;DR
Honeywell-backed Quantinuum has filed for a US IPO, targeting a valuation above $20 billion. The quantum computing company, pricing in a fault-tolerant machine planned for 2029, reported annual revenue of $30.9 million and a loss of $192.6 million.
How many filed for a US initial public offering on Thursday that could value the company at more than $20 billion. For the year ended December 31, 2025, Quantinum reported revenue of $30.9 million and a net loss of $192.6 million. The company is asking public market investors to pay a premium of more than 600 times revenue for the quantum computer, which is not yet available in its final form. The computer he is building, a fail-safe universal machine called Apollo, is scheduled for 2029.
The appeal is significant not because of Quantinuum’s current financials, which are modest by any standard, but because the IPO market’s appetite will reveal how investors value technology five to ten years away from commercial service over the past two decades. Quantinuum is backed by Honeywell, which owns 54 percent of the company. JPMorgan and Morgan Stanley are leading the offering. The ticker will be QNT on the Nasdaq Global Options Market.
Company
Quantinuum was created in 2021 by the merger of Honeywell Quantum Solutions and Cambridge Quantum Computing. He builds quantum computers based on trapped ion architectures, a technology in which individual atoms are suspended in electromagnetic fields and manipulated with lasers to perform calculations. The company claims the highest average two-qubit gate fidelity in the industry by December 2025, a measure of how accurately a machine performs the basic operations of quantum computing.
Its clients include BMW, Airbus, JPMorgan Chase, HSBC, Mitsui and Thales. BMW expanded its multi-year partnership with Quantinuum in May 2026, applying quantum computing to research on catalyst chemistry for fuel cells. Airbus is exploring quantum simulation for hydrogen-powered aircraft. JPMorgan has been working with Quantinuum since 2020 and is one of the most active enterprise users of the software development kit.
These are research partnerships, not production placements. No company is running quantum computing in manufacturing at a scale that impacts its bottom line. The partnerships exist because companies believe that quantum computing will eventually transform their industries, and they want to be ready when it does. The word “eventually” carries all the risks.
Numbers
Quantinuum’s 2025 revenue of $30.9 million represents a 34 percent increase from $23 million the previous year. The net loss of $192.6 million was up 34 percent from $144.1 million a year earlier. Income and losses increased at the same rate.
The first quarter of 2026 was worse. Revenue fell to $5.2 million from $19.1 million in the same quarter a year ago. Net loss increased from $30.5 million to $136.6 million. The quarterly numbers show that revenue is tight and contract milestones depend on the timing, a common pattern among pre-commercial deep tech companies.
A target valuation of more than $20 billion would represent a doubling from the $10 billion pre-money valuation Quantinuum raised $600 million in September 2025. Before that, it raised $300 million in January 2024 at a $5 billion valuation. The valuation quadrupled in two years, while the company’s revenue rose from $23 million to $31 million.
Road map
Quantinuum’s hardware roadmap consists of four generations. The current system Helios is commercially available. Sol is planned for 2027. The Apollo system, which the company describes as universal and fully fault-tolerant, is planned for 2029. A fault-tolerant quantum computer, capable of performing complex calculations with enough error correction to produce reliable results, is the threshold at which quantum computing moves from a research tool to a commercial platform.
Riverlane has raised $75 million to create chips that solve quantum error correctionIt aims for one million error-free transactions by 2026. Error correction is a major engineering problem in the field. Without it, quantum computers produce results that are too noisy to be useful for the complex simulations that justify the theoretical advantages of the technology. Quantinuum’s Apollo is designed to solve this problem at the system level. Whether this will happen and whether 2029 is achievable are the questions on which the IPO valuation is based.
Europe is spending billions on quantum computersThe governments of Germany, the Netherlands, France, and the United Kingdom are launching or expanding national programs. France has allocated 500 million euros to five startups developing crash-resistant quantum machines.. The public investment reflects a consensus among policymakers that quantum computing is a strategic capability, even as the private market struggles to determine the value of the capability before it goes live.
market
Quantinuum will join a small group of publicly traded quantum computing companies. IonQ, which uses the same trapped ion technology, went public through a SPAC in 2021 and is the only pure quantum stock with positive returns in 2026, up 16 percent year-to-date after more than $100 million in annual revenue. Righetti Computing, which uses superconducting qubits, fell 10 percent. D-Wave Quantum fell 9 percent.
IQM has built 30 full-stack quantum computers It exited its facility in Finland and announced a $1.8 billion SPAC merger to list on the NYSE. The quantum computing sector comes before profits and is largely driven by sentiment, with share prices moving on milestone announcements, government contracts and capital raises rather than fundamentals. Quantinuum’s IPO will be the largest quantum computing listing to date and will set the valuation benchmark for the entire sector.
The risk is that the benchmark reflects the market’s enthusiasm for a technology whose commercial timeline remains uncertain. In 2025, industry experts surveyed said the quantum benefit is at most a decadea timeline that hasn’t changed meaningfully in a decade. Google CEO said five to ten years. NVIDIA’s CEO said at least fifteen.
Bet
Honeywell’s decision to take Quantinuum public is part of a broader restructuring that includes splitting off its aerospace division and spinning off its advanced materials business. The IPO gives Quantinuum access to the public capital markets and allows Honeywell to gradually reduce its 54 percent stake. The $600 million raise in September 2025 was led by investors including JPMorgan, which is now leading the IPO underwriting, a dual role that reflects how aligned the interests of the investment banking community are with the offering’s success.
Quantinuum’s launch is a bet that public market investors will value a quantum computing company like the private markets: one with the promise of a future-proof technology that doesn’t yet work at scale. And the income of 30.9 million dollars is not a product. The product is three years old, and it is the Apollo, a machine with several fundamental engineering advances. The IPO is a bet that the market will pay $20 billion in waiting fees.
