The race to commercialize quantum computing reached another milestone Thursday as IQM Quantum Computers made its public market debut, but investors gave the Finnish technology company a cautious welcome.

Shares of IQM fell about 3.4% on their first day of trading on the Nasdaq, after the company completed a $1.8 billion merger with a special-purpose acquisition company (SPAC). The company now trades under the ticker IQMX, becoming the first European quantum computing company listed on a major U.S. exchange.

Trading was volatile throughout the session.

The stock dropped as much as 7.5% before recovering some losses to close lower, underscoring the uncertainty surrounding valuations for companies operating in one of the world’s newest and most promising technologies.

IQM reached the public market through a merger with Real Asset Acquisition Corp., a SPAC created to acquire a private business. The transaction valued the Finnish company at approximately $1.8 billion before additional capital was raised.

The deal generated roughly $233 million in new funding through the merger and a related private investment. Following the transaction, IQM expects to hold more than $450 million in cash, giving the company significant resources to continue developing its technology.

Quantum computing is an expensive business.

Building quantum computers requires specialized equipment operating at temperatures close to absolute zero, along with years of intensive research and engineering before commercial returns can be realized.

Unlike many startups, IQM already has paying customers.

The company develops complete quantum computing systems—including hardware, software, and cloud-based access—and serves research institutions and national computing centers such as VTT Technical Research Centre of Finland and Germany’s Leibniz Supercomputing Centre.

According to the company, it has built more than 30 quantum computers, delivered 18 systems to customers, and expanded its customer base from eight paying clients in 2024 to 22 during 2025.

Even so, the business remains in its early stages.

IQM generated approximately $36 million in annual revenue during its latest fiscal year and has yet to report a profit. Chief Executive and co-founder Jan Goetz has argued that IQM stands apart from many competitors because it is already delivering working machines rather than simply pursuing laboratory research.

One disclosure in the company’s prospectus drew particular attention.

IQM warned investors that large-scale commercial adoption of quantum computing may never occur. While similar risk disclosures appear throughout the industry, the unusually direct language highlighted the uncertainty that still surrounds the technology despite growing investor enthusiasm.

The company enters a rapidly expanding market.

Several quantum computing companies have pursued public listings during 2026, many through SPAC mergers. Rival Infleqtion debuted on the New York Stock Exchange earlier this month, while companies including Pasqal of France and Xanadu Quantum Technologies of Canada have also announced plans to access public markets.

Investors remain cautious after the previous SPAC boom in 2021, when many highly valued startups later struggled to meet expectations.

Competition is also intense.

IQM’s superconducting technology competes directly with systems being developed by IBM, Google, and publicly traded Rigetti Computing, while rivals including IonQ, D-Wave, and Quantinuum are pursuing different quantum computing architectures.

Government investment continues to accelerate the sector.

President Donald Trump has signed executive actions intended to strengthen U.S. leadership in quantum technology, while the U.S. Department of Energy has set a goal of deploying a scientifically useful, fully reliable quantum computer by 2028.

IQM has already established a research center in Maryland and installed a quantum computer at Oak Ridge National Laboratory, giving the Finnish company an expanding presence in the American market.

For investors, the opportunity is significant—but so is the risk.

Quantum computing has the potential to transform industries ranging from pharmaceutical research and advanced materials to cybersecurity and artificial intelligence. Yet meaningful commercial adoption could still take years, and companies like IQM continue investing heavily while generating relatively modest revenue.

Thursday’s subdued market debut suggests Wall Street remains optimistic about quantum computing’s long-term promise while remaining cautious about how quickly that promise will translate into profits.

The company also began trading in Helsinki, maintaining a home-market listing alongside its new U.S. shares. For now, IQM has capital, customers, and ambitious growth plans—but investors are still deciding what that future is worth.
