Quantum Stocks (IonQ, Rigetti, D-Wave, Quantum Computing Inc) Surge 700–6,000% – Bubble or Breakthrough? (Oct. 13, 2025)
Rigetti shares jumped nearly 4,000% year-over-year by mid-October 2025, with IonQ up 700% and D-Wave 2,000%, despite none of these quantum firms posting profits or significant revenue. IonQ traded near $75, Rigetti at $47, and D-Wave at $33. Recent gains followed major contracts, acquisitions, and product launches. Analysts and commentators warn valuations far exceed fundamentals, calling the rally speculative.
