IonQ's stock rose 9% following a research breakthrough in quantum optimization circuits developed with NVIDIA and partners, improving setup efficiency for quantum machines. This progress sparked gains in peer quantum computing stocks like D-Wave (8%) and Rigetti (7%), though the broader quantum ETF moved modestly, indicating a speculative rally centered on IonQ rather than a sector-wide revaluation. Investors should watch if IonQ's research translates into revenue and sustained growth, as current gains reflect thematic enthusiasm rather than firm customer adoption.
IonQ shares are up 9.91% at USD 40.49 on Pluang as of Sep 17, 2026 23:02 WIB, showing strong investor interest. D-Wave also gained 8.48% to USD 17.65, while Rigetti rose 8.59% to USD 16.06. Despite these gains, D-Wave's Pluang order activity is mostly sell at 97%, contrasting with IonQ's 92% buy activity, highlighting differing investor sentiments within the quantum sector.
