NEW YORK, December 31, 2025, 2:57 PM ET — Regular session
- IonQ shares were down 0.1% at $45.26 in afternoon trading, lagging a cautious year-end tape.
- Investors have been tracking quantum-computing names closely as thin holiday liquidity can amplify moves.
- IonQ’s latest company update highlighted a planned 100-qubit system delivery to South Korea’s KISTI.
IonQ, Inc. shares dipped in afternoon trading on Wednesday as investors navigated the final session of the year with light volumes and a cautious tone. The stock was down 0.1% at $45.26.
The muted move matters because IonQ sits in a small group of quantum-computing stocks that have been prone to sharp swings on headlines, with year-end positioning often exaggerating daily price action.
Risk appetite was already fragile as U.S. stocks slipped in holiday-thin trading, with technology weighing on the broader market even as the main indexes remained on track for annual gains. 1
The latest company catalyst came earlier this week when IonQ said it finalized an agreement with South Korea’s Korea Institute of Science and Technology Information (KISTI) and would deliver a 100-qubit IonQ Tempo quantum system. “This is a defining moment for both IonQ and South Korea,” Chairman and CEO Niccolo de Masi said. 2
A qubit is the basic unit of information in quantum computing. In simple terms, more qubits can increase the size of problems a quantum machine can work on, though performance also depends on error rates and how well systems run reliably.
IonQ said the system will be integrated into KISTI-6, a high-performance computing (HPC) cluster — essentially a large, tightly connected supercomputing environment — in what the company described as the country’s first onsite hybrid quantum-classical integration. IonQ said users will be able to access the platform remotely through a secure private cloud.
Other quantum-computing stocks were mixed on the day, underscoring the sector’s headline-driven churn. D-Wave Quantum rose 1.4%, while Rigetti Computing fell 0.9% and Quantum Computing Inc slipped 0.4%.
Macro data also set the backdrop for growth stocks. U.S. weekly jobless claims fell unexpectedly to 199,000, according to Labor Department data, a report published a day early ahead of the New Year’s holiday. 3
The next major labor-market checkpoint is the December employment report due on January 9, which investors will use to reassess the outlook for interest rates. 4
IonQ’s shares have pulled back sharply from late-December levels, reflecting the volatility that has defined the quantum-computing trade. The stock is down about 16% from its Dec. 22 close, based on daily pricing data. 5
Traders are watching whether IonQ can regain momentum above the mid-$40s while the company works through delivery timelines and customer adoption of new systems, a key proof-point for revenue conversion in early-stage quantum businesses.
Wall Street also has an eye on the next earnings cycle. Zacks projects IonQ’s next earnings release around Feb. 25, though timing can shift as companies set their calendars. 6
For now, with year-end volumes thin, IonQ’s day-to-day direction is likely to hinge on risk sentiment and any incremental updates that show contract announcements turning into deployed systems and recurring usage.
