Insiders Dump $895M as Quantum-Computing Stocks Rally

Insiders at IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. have sold about $895 million of their shares since Sept. 2024, with minimal insider purchases to offset it. Despite two-year stock surges—IonQ ~400%, Rigetti ~1,820%, D-Wave ~1,670%, QUBT ~1,200%—valuation metrics remain extreme (P/S ratios well above 30 for all four), signaling potential bubble risk as quantum computing remains in an early development phase. The article cautions that while partnerships and deals exist, investors should temper expectations for near-term gains.
