NYSE:IONQ 26 December 2025 - 10 August 2026

IonQ, Inc. stock heads into the final trading days of 2025 with momentum cooling after a sharp holiday-week pullback, even as Wall Street’s newest coverage on the quantum-computing pure play remains broadly constructive. Shares last closed at $46.00, after a 7.67% one-day slide on Friday, Dec. 26, a move that stood out in an otherwise quiet, low-liquidity session across U.S. equities. StockAnalysis+1

IonQ, Inc. stock is heading into the final trading days of 2025 with momentum still split between two powerful narratives: growing commercial traction for quantum hardware and networking, and persistent concerns that the share price has been discounting a best-case future far ahead of today’s fundamentals.

IonQ, Inc. heads into the final stretch of 2025 with momentum—and volatility—still defining the trade. Shares finished Friday’s session at about $46, down roughly 7.7% on the day after opening near $49.6 and dipping into the mid-$45 range, according to end-of-day data from the company’s investor site and market quotes.
