Quantum Computing Enters the Spotlight in Public Markets

Quantinuum has reported a loss of nearly $200 million last year and experienced a revenue decline in the first quarter of 2026, all while suggesting its technology might never come to fruition—yet investors are eager to purchase the stock.

The quantum-computing company has increased both the price and quantity of shares it plans to issue on the Nasdaq prior to its public launch on Thursday, signaling demand that exceeds expectations.

Quantum computing is an emerging technology with the potential to tackle problems beyond the capabilities of existing machines, offering commercial advantages in fields such as drug discovery and defense. Numerous startups, as well as tech giants like IBM and Google, are in a competitive race to develop a quantum computer capable of delivering these advantages.

This is costly endeavor. Recently, several companies have capitalized on soaring tech valuations by going public to secure necessary funding, as investors rush to get involved in the burgeoning market. The number of publicly listed quantum computing firms in the US has doubled since the beginning of the year.

Federal support for the technology may have reassured some investors. In May, the US Department of Commerce announced a $2 billion investment across nine quantum companies, with $100 million allocated to Quantinuum. This endorsement of the companies’ strategic plans is expected to have provided a “tailwind,” facilitating investor backing for Quantinuum ahead of its market debut, according to Prineha Narang, a professor of physical science and electrical and computer engineering at the University of California, Los Angeles.

While Quantinuum is the fourth company in its sector to list in the US this year, it will be the first to undergo the more gradual and regulated initial public offering process.

“You could say that quantum hasn’t faced its challenges yet,” Narang observes. “This is precisely why many companies and investors are closely monitoring the Quantinuum IPO.”

None of the companies have developed a quantum computer that is sufficiently powerful to be commercially viable at this point. Whether or when that will happen remains unclear. “In quantum thus far, with most companies and stocks, you’re not investing in a business yet; you’re investing in a probability,” states Olivier Roussy, CEO of quantum security firm BTQ Technologies.

Update 6/17/26 9:30 am EDT: This story has been updated to clarify that Quantinuum is going public on the Nasdaq.
