IonQ, Inc. (IONQ) Stock Jumps on Quantum-AI and Defense Deals: December 4, 2025 Outlook
IonQ’s stock is having another very “on‑brand” quantum day: volatile, loud, and hard to ignore. Around midday on December 4, 2025, IonQ, Inc. (NYSE: IONQ) was trading in the mid‑$50s, up double digits intraday after a string of headlines tying the company to biotech, defense drones, and big institutional money. StockAnalysis shows the shares around $54.20, up about 11%, in early afternoon trading. StockAnalysis+1 At the same time, fresh filings show Norges Bank, Norway’s central bank, has quietly taken a 1% stake, while analysts and commentators argue over whether IonQ is still the quantum market’s crown jewel or yesterday’s hype.
