Quantum computing stocks are falling roughly ten times harder than the broader NASDAQ 100 on Monday, with no fresh negative catalyst driving the selloff.
Invesco QQQ Trust (NASDAQ: QQQ) is down just 0.7% to $708.26 in afternoon trading, making the quantum sector’s decline look especially pronounced by comparison.
Rigetti Computing (NASDAQ: RGTI) is down 7% to $16.70, surrendering a significant portion of the gains it posted on last week’s revenue-driven momentum.
IonQ (NYSE: IONQ) is down 6% to $42.27, tracking the sector reversal in what analysts describe as a sympathy move across the entire quantum basket.
Quantum Computing Inc. (NASDAQ: QUBT) is down 7% to $8.32, unwinding part of a substantial post-earnings surge that followed a blockbuster revenue report last week.
Infleqtion (NYSE: INFQ) is also down 7% to $13.14, while D-Wave Quantum (NYSE: QBTS) shares are also trading lower alongside the broader group.
Last week’s rally was ignited when Quantum Computing Inc. reported second-quarter revenue of $5.6 million, representing a gain of more than 9,000% above the $61,000 it posted in the same quarter a year earlier.
Infleqtion added fuel to the sector’s surge after originally reporting second-quarter revenue up 116% to $12.6 million, then raising that figure to $13.5 million, a 157% increase, in an amended SEC filing submitted five days later.
That amendment landed on August 12 and pushed the reported growth rate materially higher, though most coverage of the sector narrative missed the revision entirely.
Monday’s broad pullback reflects sentiment-driven de-risking across the basket rather than any single company-specific negative development hitting the wire.
The extraordinary percentage gains cited across these companies say more about how small their prior-year revenue bases were than about how close quantum computing is to commercial scale.
Quantum Computing Inc. went from just $61,000 in the year-ago quarter to $5.6 million, a figure that looks enormous only because the starting point was near zero.
Infleqtion’s amended revenue revision moved the year-over-year growth rate from 116% to 157% on a single restated line item, illustrating how sensitive these percentages are to small absolute dollar changes.
Quantum Computing Inc.’s reported backlog of roughly $42.5 million as of June 30 also looks modest when measured against the company’s own market capitalization.
These stocks increasingly trade as a single correlated basket, meaning a bullish headline at one company lifts the entire group, and a reversal hits all of them simultaneously.
In the background of Monday’s move, Rigetti Computing’s chief operating officer, David Rivas, sold 9,038 shares on August 20 in a routine tax-withholding transaction tied to vested restricted stock units, while continuing to hold 316,907 shares directly.
Rigetti Computing was down 19% year to date through Friday’s close, and Quantum Computing Inc. was down 13% year to date, while IonQ was essentially flat over the same period.
Against the Invesco QQQ Trust’s 16% year-to-date gain through Friday, the quantum basket has spent most of 2026 trailing the broader NASDAQ 100 even before Monday’s slide began.
Investors holding positions across RGTI, IONQ, QUBT, INFQ, and QBTS should treat them as a single high-beta allocation rather than as diversified exposure to the quantum computing theme.
Any fresh government funding disclosure or analyst note could quickly reset sentiment for the group, given how thinly current fundamentals support these companies’ market capitalizations.
