Why IonQ Stock Popped Today - The Motley Fool

IonQ (IONQ -3.00%) stock jumped 9.5% through 12:30 p.m. ET Thursday after announcing a new "breakthrough" in quantum computing -- and with help from Synopsys (SNPS +1.00%). Image source: Getty Images. IonQ + Synopsys: Better together? Synopsys is best known as a maker of software for semiconductor chip design, but this new development goes in a different direction. As IonQ explains, it cooperated with Synopsys to use "quantum algorithms integrated into mainstream engineering software" to accelerate industrial design work -- specifically, designing "complex car and jet engine simulations" -- by up to 14.6%. And to be honest, this sounds like a problem tailor-made for quantum computing to solve. "Larger scale simulations, such as those used for virtual crash tests and aerodynamic analysis, can require significant compute resources," explains IonQ. "Those resources are necessary to solve large systems of equations containing hundreds of millions of variables." Because quantum computing solves large numbers of variables simultaneously, it speeds up the testing. More than that, IonQ says that using quantum can help companies identify which calculations don't need to be solved at all, speeding up the process even further by optimizing the workflow.

It's less clear, however, how big a benefit this is for IonQ stock. While the research is interesting, the company's press release doesn't mention any specific revenue benefit for IonQ itself. With IonQ still unprofitable and expected to remain so for the foreseeable future, I continue to view IonQ stock as entirely speculative -- maybe good for momentum traders, but unsuitable for traditional investors.Read NextSep 18, 2026 •By Will EbiefungHere's What $1,000 Invested in IonQ Stock Could Be Worth by 2030Sep 17, 2026 •By Geoffrey SeilerIf the Pace of AI Is Slowed, Investors Can Turn to Quantum Computing. 4 Quantum Stocks to Buy Now.Sep 16, 2026 •By Robert IzquierdoIonQ CEO Sells Over 16,000 Shares Worth Nearly $600,000 After the Company Raised Its Full-Year Sales OutlookSep 16, 2026 •By Manali Pradhan, CFAIonQ vs. Rigetti Computing: Which Pure-Play Quantum Stock Actually Has the Technology Edge?Sep 13, 2026 •By Scott Levine3 Best Tech Stocks to Buy in 2026 and How to InvestSep 12, 2026 •By Robert IzquierdoBigBear.ai vs. IonQ: Weighing Whether to Invest in the Artificial Intelligence Company or the Quantum Computing GiantAbout the AuthorRich Smith is a contributing Motley Fool defense and stock market analyst covering publicly traded and emerging companies in defense, space, aerospace, and other sectors.
