Quantum computing stocks are giving back ground, and the group’s largest name is leading the retreat. IonQ (NYSE:IONQ | IONQ Price Prediction) stock is at $28.39, down 8% in early trading. The slide cuts a strong bounce over the past week, and IonQ stock remains down 34% year to date (YTD).

Speculative tech has been under pressure as fallout around NVIDIA (NASDAQ:NVDA) weighs on AI-adjacent stocks. IonQ’s high-beta profile leaves it exposed to that shift in risk appetite.

IonQ Stock Retreats After a Record Quarter

IonQ reported its Q3 2026 results on November 5, and the top line beat expectations. The company’s revenue reached $173.83 million against a $141.20 million consensus estimate, up 336% year over year (YoY), as the newly acquired SkyWater foundry business was consolidated. Management also raised its full-year 2026 revenue guidance to $505 million to $515 million.

Headline profit at IonQ got a one-time lift. A non-cash warrant liability gain of $896.16 million lifted the company’s net income under generally accepted accounting principles (GAAP) to $563.96 million. On an adjusted basis, which excludes that gain, IonQ lost $0.29 per share, and its adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) loss extended to $133.61 million from $48.91 million.
