Quantum Insiders Net Sell $863 Million as IonQ, Rigetti and D-Wave Trade at 69x to 532x Sales

Summary
$863 million in net insider selling has piled up over three years at IonQ, Rigetti and D-Wave, with open-market buying across the trio described as nearly nonexistent.
That caution stands against a huge stock rally: the three pure-play quantum names posted explosive gains over the past two years, with trailing 12-month returns peaking around 6,200%.
Valuation is the clearest concern, with price-to-sales ratios at 68.87 for IonQ, 406.82 for Rigetti and 532.38 for D-Wave despite quantum computing still being far from broad commercial adoption.
Fundamentals have improved in 2026, however: IonQ's Q2 revenue jumped 287% to $80.1 million, D-Wave's first-half bookings rose 1,120%, and Rigetti is advancing a 108-qubit roadmap while seeking up to $100 million in U.S. support.
Why are quantum computing executives quietly dumping nearly a billion dollars in stock while their companies report record-breaking growth?
Will explosive hardware advancements and strategic cloud partnerships be enough to save quantum computing companies from their extreme market valuations?
Could the massive gap between quantum tech valuations and actual commercial revenue trigger a sudden crash for these emerging stocks?
