Quantum Stocks Drop Amid Tech Selloff; Lam Research Cites Supply Constraints
What happened
On October 24, 2026, quantum computing stocks declined during a broad technology selloff. Quantinuum dropped 7%, while IONQ fell 3%. The decline was immediately triggered by comments from Lam Research CFO Doug Bettinger, who warned that supply constraints might push some December-quarter shipments into March.
Why it matters
The sharp decline in quantum stocks reflects their position at the riskiest end of the AI trade. These stocks often fall harder than the broader market when negative sentiment emerges, as their valuations rely heavily on future revenue projections.
