Quantum Computing Market Potential and Stock Trends
Quantum computing has emerged as a significant opportunity, with the market projected to reach $1 trillion by 2035, according to The Quantum Insider. Notable stocks in this sector, including IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), D-Wave Quantum (NYSE: QBTS), and Quantum Computing Inc. (NASDAQ: QUBT), saw their shares increase by up to 5,400% in 2025, fueled by major partnerships and investments. However, insider trading activity reveals a concerning trend, with insiders of these companies selling approximately $840 million more in stock than they have bought over the past three years.
As of January 9, 2026, IonQ led with $460.8 million in net selling activity, followed by D-Wave Quantum at $292 million, Rigetti Computing at $53.5 million, and Quantum Computing Inc. at $33.2 million. While the sector shows promise, experts warn that the lack of insider buying might indicate potential overvaluation, with all four companies currently trading at high price-to-sales ratios that could signal a market bubble.
