The stock has jumped more than 66% in a month, helped by Nvidia's April Ising model launch and IonQ's DARPA selection and earlier $54.5m US Air Force contract.
IonQ is using trapped-ion hardware and says it has reached 99.99% two-qubit gate fidelity, while targeting a 256-qubit system by end-2026 after deploying a 100-qubit machine.
The company reported 2025 revenue of $130m, expects $225m-$245m in 2026, and is pursuing acquisitions and hybrid quantum-GPU partnerships, including with South Korea's KISTI, to broaden adoption.
Is Nvidia's AI playbook making quantum firms like IonQ partners or just components in its new empire?

IonQ’s Quantum Leap: Nvidia AI Catalyst, DARPA Contract, and $2B Funding Drive 256-Qubit Scaling
Overview
In 2026, Nvidia's release of Ising AI models sparked a major shift in market sentiment toward quantum computing, driving IonQ's stock to surge over 60% in a week and more than 50% monthly. This rally was fueled by the strong synergy between Nvidia's AI models and IonQ's trapped-ion technology, enhancing system reliability and scalability. IonQ's leadership was further solidified by securing the DARPA HARQ contract, backed by its record-setting qubit fidelity and pioneering quantum networking achievements. With a clear roadmap targeting a 256-qubit system deployment at Cambridge and robust financial backing from a $2 billion equity offering, IonQ stands poised for growth amid strong analyst optimism, despite ongoing operational challenges.
