rigetti ionq and other quantum stocks might be in a bubble

IonQ and Rigetti stock prices have jumped in the past few years, transforming them into multi-billion-dollar companies. RGTI stock has jumped by 5,255% in the last 12 months, bringing its market capitalization to over $12 billion. IonQ stock, on the other hand, has jumped by 692% in the same period, bringing it valuation to over $23 billion. This article explores why these companies are pointing to a quantum computing bubble that could pop in the coming months or years. Quantum computing stock like IonQ and Rigetti Computing have done well as investors bet that the industry will become the next big thing in the technology industry. Some experts believe that the industry might become the next big thing once the artificial intelligence hype fades.

This view is supported by reports by some of the most respected organizations in corporate America. McKinsey, a top consulting company, noted that the industry would likely jump into a $100 billion market by 2030 and that companies in the sector will hit $95 billion in revenue by 2035. The report also predicted that the industry will be worth almost $200 billion by 2040. All information and data in this article is solely for informational purposes.

That was the question Twitter Tom posed during our latest Market on Close livestream — and when Senior Market Strategist John Rowland pulled up the data, his verdict was clear: “Yeah, I think this is definitely a bubble.” Let’s unpack why John says so — and which other corners of the market may be showing the same warning signs. IonQ, Rigetti Computing, D-Wave Quantum, and Quantum Computing have reached valuation levels well beyond those seen during prior stock market bubbles. Each of these companies has recently raised capital through a series of equity offerings and stock issuances. These moves could suggest that the valuation levels for these businesses are not only abnormally high, but unsustainable.

Last summer, companies such as IonQ (NYSE: IONQ), Rigetti Computing (NASDAQ: RGTI), D-Wave Quantum (NYSE: QBTS), and Quantum Computing (NASDAQ: QUBT) were unknown penny stocks. However, as quantum computing steadily made its way toward center stage in the artificial intelligence (AI) realm, each of these companies witnessed meteoric rises in their share prices. Over the last 12 months, IonQ stock has blasted higher by 517%, while Rigetti, D-Wave, and Quantum Computing have experienced surges of at least 1,500% as of this writing (July 21). Written by Keithen Drury for The Motley Fool-> IonQ's quantum computing approach yields more accurate results. Rigetti Computing has not yet been advanced to the next stage of a key government-funded quantum computing benchmarking initiative.

The quantum computing investment landscape has shifted multiple times in 2025. At the start of the year, after an impressive December 2024, quantum computing pure-play stocks all sold off. Throughout 2025, upward momentum returned, and several quantum computing stocks are on course for impressive one-year returns. However, these stocks all sold off starting in October as the market's appetite for risk declined. IonQ (NYSE: IONQ) and Rigetti Computing (NASDAQ: RGTI) are both well down from the highs they touched in October: IonQ is off by around 43%, while Rigetti is down about 60% from its peak. Could either one enjoy a resurgence in 2026?
