quantum computing stocks dropped over 40 after nvidia ceo prediction

Quantum computing stocks dropped Wednesday after Nvidia CEO Jensen Huang declared that useful quantum computers are many years away. "If you said 15 years for very useful quantum computers, that would probably be on the early side," he said during Nvidia's analyst day. "If you said 30, it's probably on the late side. But if you picked 20, I think a whole bunch of us would believe it." Huang said he believes Nvidia will play a "very significant part" in creating the computers and helping the industry "get there as fast as possible." Stocks tied to quantum computing tumbled on the heels of the comments, with Rigetti Computing plunging 40%, while IonQ shed 37%.

D-Wave Quantum dropped more than 30%, while the Defiance Quantum & AI ETF fell 4%. Quantum Computing, which announced a stock offering to raise $100 million, sank 37%. "As valuations have become a bit lofty, we're not surprised by today's correction," said AXS Investments CEO Greg Bassuk, calling the reaction somewhat "overblown." Several stocks across the quantum computing industry, including Rigetti Computing (RGTI), D-Wave Quantum (QBTS), IonQ (IONQ), and Quantum Computing (QUBT), fell sharply Wednesday following comments from Nvidia (NVDA) CEO Jensen Huang about the technology. Huang said at an analyst event Tuesday that "very useful quantum computers," which could make a number of computing tasks more efficient, are likely 15 to 30 years away. "If you kind of said 15 years for very useful quantum computers, that would probably be on the early side," Huang said.

"If you said, you know, 30, it’s probably on the late side. But if you picked 20, I think a whole bunch of us would believe it." Huang also said Nvidia is an ideal partner for quantum computing companies because "it turns out that you need a classical computer to do error correction with the quantum computer, and that classical computer... D-Wave Quantum was down 33% Wednesday afternoon, while Rigetti, IonQ, and Quantum all declined around 40%. The Defiance Quantum (QTUM) exchange-traded fund (ETF), made up of the listed companies along with other chip and tech companies like Nvidia, was down 4.5%. The quantum computing sector experienced a significant setback on Wednesday as Nvidia (NVDA) CEO Jensen Huang‘s remarks cast a long shadow over the timeline for the practical application of quantum computers.

Huang’s cautious outlook during Nvidia’s analyst day, where he suggested that “very useful” quantum computers might be 15 to 30 years away from realization, led to a sharp decline in stock prices for leading... Quantum Computing Inc. (QUBT), IonQ Inc. (IONQ), Rigetti Computing (RGTI), and D-Wave Quantum (QBTS) saw their shares plummet in premarket trading, with drops exceeding 24% for Quantum Computing, D-Wave, and Rigetti, and a 16% decrease for IonQ. This downturn was particularly stark given the recent surge in these stocks, fueled by optimism about quantum computing’s potential and amplified by Alphabet’s (GOOGL, GOOG) recent advancements in the field. Over the past year, quantum computing stocks have seen dramatic gains, with Quantum Computing Inc.

soaring by more than 1,940%, Rigetti climbing over 1,450%, D-Wave surging by more than 1,025%, and IonQ rising nearly 300%. Huang’s prediction not only affected U.S.-based companies but also had a ripple effect in Asia, notably impacting Chinese quantum computing firms like QuantumCTek Co. Ltd and Accelink Technologies Co. Ltd, whose shares also fell significantly. His statement provided a stark contrast to the bullish sentiment that had driven these stocks to new heights, suggesting that the technology’s journey to becoming a mainstream, practical tool might be much longer than... This reaction in the stock market underscores the volatility and speculation inherent in investing in cutting-edge technologies like quantum computing.

While the theoretical benefits of quantum computing, including solving complex problems in cryptography, drug discovery, and optimization, are well-documented, the practical implementation faces numerous challenges. These include not only the technical hurdles of maintaining quantum coherence and reducing error rates but also the significant investment in research and development required to make these systems viable for everyday use. Moreover, Huang’s comments reflect a broader industry acknowledgment that quantum computing, despite its promise, remains in the realm of advanced research rather than immediate commercial application. This perspective tempers expectations and might encourage a more realistic approach to investment and development in the sector, focusing on long-term growth and partnerships with classical computing technologies to bridge current gaps. A handful of quantum computing stocks have skyrocketed as some paint the technology as the next big technological innovation, but Nvidia CEO Jensen Huang warned analysts that any practical applications are still many years... Huang said Nvidia is not worried about quantum computing and added that practical applications for the nascent but powerful computers are at least 15 years away or more.

“And so if you kind of said 15 years for very useful quantum computers, that’d probably be on the early side. If you said 30 is probably on the late side. But if you picked 20, I think a whole bunch of us would believe it,” Huang told analysts, according to Axios. Quantum computers, which are powered by atom-sized “qubits” that operate via the rules of quantum mechanics, have been shown to be extremely powerful, but only in certain situations. They are distinct from existing “classical” supercomputers, which operate more similarly to a basic laptop, albeit at a much higher level. Last month, Google researchers announced its homegrown Willow quantum-computing chip could solve a complex math problem that would’ve taken the most powerful existing supercomputers 10 septillion years, or more than the estimated age of...

Several stocks across the quantum computing industry, including Rigetti Computing (RGTI), D-Wave Quantum (QBTS), IonQ (IONQ), and Quantum Computing (QUBT), fell sharply Wednesday following comments from Nvidia (NVDA) CEO Jensen Huang about the technology. Huang said at an analyst event Tuesday that "very useful quantum computers," which could make a number of computing tasks more efficient, are likely 15 to 30 years away.

28, 2025, 12:45 p.m. ET — Market closed (Weekend). Quantum computing stocks are heading into the final trading week of the year with a familiar mix of promise and turbulence—exactly the kind of setup that can amplify both opportunity and risk when liquidity... In the most recent regular session (Friday), several of the best-known “pure-play” quantum names posted sharp declines even as the broader U.S. market largely drifted in quiet, post-holiday trade. IonQ (IONQ) finished at $46.00, down about 7.6%.

Rigetti Computing (RGTI) closed at $22.38, down roughly 8.6%. D-Wave Quantum (QBTS) ended at $25.29, down about 8.1%. Quantum Computing Inc. (QUBT) closed at $10.66, down around 6.5%. That kind of synchronized pullback is not unusual for the sector: quantum “pure plays” often trade like a single high-beta theme—moving together on sentiment, valuation, and market microstructure—especially when volumes are lighter than normal. Friday’s session came in the heart of the year-end “Santa Claus rally” window, when trading volumes often thin out and day-to-day moves can become exaggerated, particularly in smaller, story-driven stocks.

[1] Home | Updates | Quantum computing stocks drop sharply after Nvidia CEO’s warning Over $8 billion in market value was lost as quantum stocks dropped following a warning from Nvidia’s CEO. Quantum computing stocks experienced a sharp decline on Wednesday following comments from Nvidia CEO Jensen Huang, who predicted practical quantum computers are still two decades away. His timeline dampened expectations in a sector already facing significant investment without broad applications. Rigetti Computing, D-Wave Quantum, Quantum Computing, and IonQ saw their shares plummet over 40%, with more than $8 billion in combined market value lost.

Investment chief Ivana Delevska of Spear Invest, which holds Rigetti and IonQ shares, supported Huang’s prediction, noting it took Nvidia a similar period to develop accelerated computing. The sector had previously surged due to a technological breakthrough at Google, with stocks rising at least threefold last year. Despite the optimism, revenue generation remains minimal, with IonQ valued at over $10 billion but expected to generate just $41.6 million in 2024 revenue.
