Quantum Computing Stocks Plunge Amid Tech Sector Pullback and Policy Risks
Shares of quantum computing firms faced steep declines on October 22, with D-Wave Computing (QBTS) dropping 15.2%, IonQ Inc. (IONQ) falling 6.8%, and Rigetti Computing (RGTI) sliding nearly 9%. The sell-off mirrored a broader retreat in tech stocks, despite a strong year-to-date rally fueled by institutional investments and government support.
Policy risks emerged as a key driver. Reports suggest the U.S. may impose software export curbs to China, targeting advanced computing and AI tools—a MOVE that could disrupt global supply chains critical to quantum firms. Stricter export rules threaten research partnerships and hardware access, compounding investor concerns.
The sector's downturn contrasts sharply with its 2025 momentum, where commercial milestones and corporate adoption had propelled gains. Market participants now weigh geopolitical headwinds against the technology's long-term potential.
