Quantum computing stocks took a sharp downturn on Monday, driven by comments from influential tech leaders Mark Zuckerberg and Jensen Huang, who expressed doubts about the immediate commercial applications of quantum computing technology. Zuckerberg, during an appearance on Joe Rogan's podcast, stated that quantum computing is still far from being a practical tool, echoing sentiments previously shared by Nvidia's CEO Jensen Huang at CES 2025. Huang had suggested that quantum computing might not be 'very useful' for another 15 to 30 years, a timeline that has contributed to the bearish sentiment surrounding quantum computing stocks.

The impact of these comments was immediate and significant. Shares of key quantum computing companies such as IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing Inc. saw substantial declines. Rigetti Computing's stock fell 15% to $7.59, D-Wave Quantum tumbled 18% to $4.70, IonQ declined 7% to $30.15, and Quantum Computing Inc. slid 10% to near $8. These declines reflect the broader market's reaction to the skepticism voiced by Zuckerberg and Huang.

Despite the downturn, some industry insiders have countered these views, arguing that quantum-based innovations are already being integrated into the tech ecosystem. D-Wave Quantum's CEO Alan Baratz, for instance, emphasized that their quantum annealing technology is already supporting businesses in solving complex challenges, suggesting that the technology is not just a futuristic concept but is being actively deployed today.

However, the market's response has been overwhelmingly negative, with investors questioning the feasibility of near-term commercial use of quantum computing. The sector had previously enjoyed significant growth in 2024, with stocks like Rigetti and D-Wave surging by 1,449% and 854%, respectively, amid high hopes for quantum computing's potential. Yet, the recent comments from Zuckerberg and Huang have triggered a reality check, leading to increased volatility and a sharp decline in stock prices.

As the quantum computing industry continues to face skepticism, the future remains uncertain but full of potential. The sector's ability to demonstrate practical applications and overcome current challenges will be crucial in regaining investor confidence. For now, quantum computing stocks remain highly volatile, with market watchers closely monitoring developments in this space.
