Prediction: The quantum computing hype could cool off in 2026 -- here's why - MSN

Key Points Quantum computing has exciting potential, but several limitations in its current state. Meaningful commercial opportunities could still be a ways off. IonQ, D-Wave Quantum, and Rigetti Computing could all struggle to support their current valuations in this market. 10 stocks we like better than IonQ › In late 2024, Alphabet announced an experimental quantum computing chip capable of performing calculations exponentially faster than traditional supercomputers. That helped ignite market-wide hype for quantum computing stocks throughout 2025. A handful of early-stage quantum computing stocks, such as IonQ (NYSE: IONQ), D-Wave Quantum (NYSE: QBTS), and Rigetti Computing (NASDAQ: RGTI), all surged to massive gains throughout the first few quarters of 2025. Although these stocks cooled off beginning in the fall, all three stocks managed full-year gains as high as 211%. Quantum computers could someday help unlock potential in artificial intelligence (AI), drug discovery, and cybersecurity, perhaps creating new industries. But despite their remarkable potential, I predict that the hype on quantum computing stocks will continue to fade throughout 2026. Here is why.
