D-Wave Quantum Shares Plunge Amid Sector-Wide Selloff and Dilution Fears
D-Wave Quantum (QBTS) experienced a significant 35.7% decline in October 2026, mirroring a broader downturn across the quantum computing sector. The selloff was largely triggered by IonQ's announcement of a $2 billion equity offering and its acquisition of Elisity, which heightened investor fears regarding capital intensive operations and potential share dilution among competitors. Despite positive operational developments—including new partnerships in South Korea and Italy—D-Wave faces scrutiny over its high valuation. The company currently trades at approximately 316 times trailing sales following a year-over-year revenue decline of 44.2%. While D-Wave maintains a healthy cash cushion of $500 million, heavy short interest continues to contribute to price volatility.
