Quantum Computing Stocks IonQ, Rigetti Computing, and D-Wave Quantum Have Put Wall Street on Notice With This $863 Million Warning

Insiders at IONQ, RGTI, and QBTS have unloaded nearly $863 million in stock over the past three years with virtually no offsetting insider purchases, raising red flags about valuation levels in the quantum computing sector. The selling comes as all three pure-play quantum names trade at extreme price-to-sales multiples: IONQ at 59x, RGTI at 398x, and QBTS at 542x.

These valuation ratios dwarf historical norms even for breakthrough technologies, suggesting the group may be due for a sharp correction. The near-total absence of insider buying during the same period amplifies concerns that company executives see current share prices as disconnected from near-term fundamentals.

The $863 million in aggregate insider sales represents a sustained pattern of distribution by those with the closest view of operational reality. For momentum-driven names that have attracted significant retail interest, the insider behavior contrasts sharply with bullish narratives around quantum computing's commercial timeline.
