Quantum Computing Insiders Have Sold $863 Million More Than They've Bought Over Three Years

Insiders at IonQ (NYSE:IONQ), Rigetti Computing (NASDAQ:RGTI), and D-Wave Quantum Inc. (NYSE:QBTS) have sold nearly $863 million more in stock than they’ve bought over the past three years, according to an analysis of Form 4 filings cited by The Motley Fool. This trend is notable given that insider buying has been minimal during this period. Despite significant gains for outside investors—some stocks seeing trailing returns as high as 6200% in two years—the companies' fundamentals have also improved, with IonQ reporting a 287% year-over-year revenue increase and raising its full-year guidance. D-Wave saw an 1120% surge in first-half bookings, while Rigetti is advancing hardware development and pursuing government funding. The high price-to-sales ratios of these firms suggest valuations may be stretched compared to historical trends for emerging technologies. However, improved financials are seen as a potential turning point from speculative hype toward commercial viability.
