Quantum computing companies are defying a turbulent market to go public this year as they seek to raise money to capitalize on recent scientific advances and move experimental technologies closer to commercialization.
One such company is Xanadu QuantumThe company, which develops quantum computing hardware and software, began trading on the Nasdaq and Toronto Stock Exchanges on Friday, rising 15% in the U.S. after a rough start in public markets.
Xanadu Quantum — Chip giant’s quantum partner Nvidia — Debuted by merging with Crane Harbor Acquisition, a special acquisition purpose company (SPAC) also known as a “blank check company.”
A SPAC is a shell company created specifically to raise money through an initial public offering, and has become a common route for quantum startups to go public.
Xanadu’s listing comes a week after the Singapore-based quantum software company horizon quantum It began trading after merging with blank check company dMY Squared Technology Group.
The narrative has shifted from scientific projects to commercial trajectories, and companies are making the most of the opportunity.

dMY Technology Group ion Q It will go public in 2021 through a merger with one of its shell companies, becoming the first publicly traded pure quantum computing company.
Since then, SPACs have become a popular path for quantum companies to raise capital, offering a faster path to going public with less regulatory oversight.
Quantum computing uses the principles of quantum mechanics to process information in ways that traditional computers cannot, with potential applications in drug discovery, materials science, cryptography, and more. Although the technology is still in its experimental stages, it is widely seen as potentially transformative.
Why now?
The recent wave of quantum listings comes at a turbulent time for global markets, as conflict in the Middle East shakes investor confidence, especially in risky speculative assets like quantum companies.
Despite ending the first day higher, Nasdaq-listed stocks xanadu Shares fell more than 10% in after-hours trading. Horizon Quantum, on the other hand, has fallen about 18% since its debut. inflectionwent public on the New York Stock Exchange in February through a blank check transaction on February 17, but its stock price plummeted more than 30%.
Still, companies appear to be venturing into these volatile markets to take advantage of recent industry breakthroughs.
Dr. Joe Fitzsimmons, founder and CEO of Horizon Quantum, told CNBC: “It’s an interesting time to get into the public markets right now with everything going on in the world. But for quantum computing, it’s actually a very ideal time to get in.”
“We’re really starting to reach something like a tipping point,” he said, adding that there have been quite a few breakthroughs in the past 18 months.

In 2024 and 2025, several companies and research groups demonstrated improvements in quantum error correction, a key requirement for building reliable machines.
Other milestones include increases in the number of qubits (which increases the potential size and complexity of the problems quantum computers can represent and help solve) and coherence times, which enable more reliable computations by reducing the effects of noise and errors.
“The first demonstration of practical quantum benefits is expected at around 100 logical qubits, a threshold that the industry will reach by 2028-2029,” Velu Sinha, a partner at Bain & Company, told CNBC.
“However, for commercially impactful applications such as drug discovery or large-scale logistics optimization, 1,000 to 10,000 logical qubits are required, which is likely to be in the mid-2030s,” he added.
This so-called “quantum advantage” refers to a theoretical milestone in which quantum computers will solve real-world problems faster, more efficiently, or more accurately than the best-known classical supercomputers.
changing story
Investment in space is on the rise as companies race to pursue quantum supremacy. Tech giants like Alphabet, Microsoft, Amazon and IBM have poured millions of dollars into the technology, but have largely avoided spinning out independent public entities.
“The narrative has moved from scientific projects to commercial trajectory, and companies are taking advantage of that window,” Sinha said.
“Quantum is one of the few technology categories that investors view as structurally inevitable…The addressable market at full maturity is estimated at $100 billion to $250 billion, giving patient capital a reason to avoid short-term volatility,” he added.
Early commercial applications are also emerging in areas such as optimization, financial modeling, and chemical simulation.
“The time was right (to go public) because quantum, and in particular neutral atoms, is moving from scientific advancement to commercial relevance,” Inflexion CEO Matthew Kinsella told CNBC.
“The initial public offering will give us capital to accelerate commercialization and invest in markets where we already see customer demand. We believe commercialization will occur in stages, with (quantum sensing and quantum timing) leading the way in the near term, and computing as performance continues to scale.”

For small quantum startups, short-term revenue opportunities are key to securing investor support for long-term research.
Horizon Quantum Computing, for example, is focused on developing software tools that can run on both classical and quantum systems, and is in a position to generate revenue before large-scale quantum hardware becomes commercially available.
The company’s CEO said the new funding will be used to expand the research team and roll out an initial iteration of the software to early access users this year.
Xanadu Quantum is also investing in a cloud-based platform that allows developers to pay a fee to experiment with quantum algorithms using their existing hardware.
From the laboratory to the real world
Historically, governments have played an important role in the development of the quantum sector, as it requires large amounts of capital.
The United States, China, and the European Union are pouring billions of dollars into quantum research and commercialization, with the aim of securing strategic advantages in computing and cybersecurity.
Government efforts have often focused on or included support from universities and national laboratories.
But the recent wave of listings highlights how the industry is transitioning from academic and public research to commercial markets, even as the timeline for adoption remains uncertain.
“Quantum computers will be able to perform trillions of calculations instantly, which will absolutely revolutionize the way we use computing,” said Mark Einstein, research director at Counterpoint Research.
Einstein said it may be decades before individuals have quantum computers in their offices or homes. But he added that a future in which large companies own the machines and provide quantum computing services could arrive much sooner.
