Quantum Computing Stocks Surge, But Analysts Warn of Potential Bubble
As of November 3, 2025, quantum computing companies IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), D-Wave Quantum (NYSE: QBTS), and Quantum Computing Inc. (NASDAQ: QUBT) have seen stock increases ranging from 294% to 3,080% over the past year. However, analysts caution that historical trends suggest a bubble could burst soon.
Boston Consulting Group estimates that quantum computing could generate between $450 billion and $850 billion for the global economy by 2040, with estimates from The Quantum Insider predicting an economic impact of $1 trillion by 2035. Despite strong stock performance, there is skepticism about the companies’ immediate profitability and market viability.
For long-term investors, Amazon (NASDAQ: AMZN) is suggested as a more stable investment option, leveraging its established e-commerce and cloud services to enter the quantum computing space. As of now, AWS contributes around 60% of Amazon’s operating income and is projected to achieve a $132 billion annual run rate in revenue.
