Save StorySave this storySave StorySave this storyQuantinuum lost nearly $200 million last year, saw revenue drop the first quarter of 2026, and says its technology may never work–yet investors are clamoring to buy the stock.The quantum-computer maker boosted the price and number of shares it will issue on the Nasdaq ahead of its public debut on Thursday, indicating higher-than-anticipated demand.Quantum computers are a nascent technology that promises to solve problems current machines can’t, unlocking commercial advantages in areas from drug discovery to defense. A multitude of startups, as well as tech giants like IBM and Google, are racing to build a quantum computer powerful enough to realize these benefits.It’s expensive work. Lately, a number of firms have taken advantage of sky-high tech valuations and have gone public to raise the necessary funds, as investors scramble to be part of the gold rush. The number of publicly traded quantum computer companies in the US has doubled since the start of the year.Government support for the technology may have somewhat reassured some investors. In May, the US Department of Commerce said that it would invest $2 billion across nine quantum companies, including $100 million into Quantinuum. That vote of confidence in the companies’ road maps will have acted as a “tailwind,” as Quantinuum secured investor support in the run-up to its debut, according to says Prineha Narang, a professor of physical science, and electrical and computer engineering at the University of California, Los Angeles.While Quantinuum is the fourth firm of its kind to list in the US this year, it will be the first to have gone through the slower, more regulated initial public offering process.“You can argue that quantum hasn't gone through the ringer yet,” Narang said. “That’s exactly why a lot of companies and investors are watching the Quantinuum IPO.”None of the firms have built a quantum computer powerful enough to be commercially valuable yet. When—and whether they ever will—remains uncertain. “In quantum to date, with most companies and equities, you’re not buying a business as of yet, you’re buying a probability,” said Olivier Roussy, chief executive officer of quantum security firm BTQ Technologies.Update: 6/17/26 9:30am edt: This story has been updated to clarify that Quantinuum is going public on the Nasdaq.CommentsBack to topTriangleYou Might Also LikeIn your inbox: Maxwell Zeff's dispatch on the business of AIAmazon thinks the future of data centers depends on a technical problem it just solvedBig Story: The painful truth about long CovidGoogle Search goes agentic—and doesn’t need you anymoreSpecial edition: AI or die trying!Topicsquantumquantum computingFinanceIPOsartificial intelligenceJabra Promo Codes: 30% Off for June 2026Unlock significant savings on Jabra headphones, headsets, and speakers with our verified promo codes, exclusive coupons, and limited-time deals in June 2026.Christopher NullTop NordVPN Coupons: 77% Off, Plus 3 Months Free in June 2026Save up to 77% on 2-year plans and get 3 free months with our NordVPN discount codes.Scott GilbertsonTop DoorDash Promo Code: 50% Off for June 2026Explore today’s top DoorDash promo codes for $25 off your first order, free delivery, and 50% off DashPass for students and select users.Molly HigginsTop Breville Promo Codes: $700 Off This JuneDiscover the top Breville coupons and discount codes for coffee machines, kitchen appliances, and fresh coffee beans, with deals up to $700 off.Louryn StrampeLimited Time: TurboTax Coupons Full Service This JuneTax season doesn’t have to be stressful.
