Up 1,200%, Should You Buy IonQ Right Now?
Summarize this article with:
IonQ has dominated investor attention over the past several years, but its gains could be a flash in the pan.IonQ's (IONQ 2.00%) share price gains over the past three years have been impressive. The stock price is up more than 1,200% since the beginning of 2023, and its shareholders are no doubt hoping the good times will continue through 2026 and beyond. But is it a good time for investors to jump on board with this popular quantum computing stock, or is it best to sit this one out? I believe investors would be better off avoiding IonQ stock for several key reasons. Image source: Getty Images. IonQ's stock is expensive As its name suggests, IonQ is focused on trapped-ion quantum computing, which enables quantum computers to operate at room temperature. While still in its infancy, this trapped-ion process can make reliable quantum computing easier to achieve and less difficult to use than ultra-cooled quantum computers, which is why the tech has piqued investor interest. With IonQ's share price skyrocketing over the past several years, it should come as no surprise that the stock is expensive. But even by the standards of high-flying tech stocks, this one is pricey. IonQ's shares have a price-to-sales ratio of 140, which is far beyond the technology sector's average P/S ratio of just under 9. That's a massive gap between the two, and it shows just how much more investors are paying to own IonQ right now.Advertisement Even if the company were profitable (it's not) and quantum computing were a sure thing (it isn't), this is a hefty price tag to pay for IonQ's shares and a clear warning for investors to stay away. The company's losses are widening IonQ delivered impressive sales growth in the third quarter, with revenue rising 222% to nearly $40 million. Despite that huge increase, the company's losses continued to expand. IonQ's non-GAAP (adjusted) loss per share was $0.17, which was worse than its loss of $0.11 per share in the year-ago quarter. It's important to note that this decline is after the one-time accounting charge and acquisition costs from the quarter have been taken out. IonQ's operating expenses are rising, too, and increased to $208 million in the third quarter, up from about $65 million in the year-ago quarter. Even with its impressive sales growth, the company continues to ramp up spending to a degree that its losses are expanding instead of narrowing.

Many tech companies, even ones working on quantum computing, say that practical use cases for the technology are still years away. Consider that Alphabet, which has made several important advancements in quantum computing, says that "useful" quantum computers are still five to 10 years away. Investors have been very optimistic about speculative investments for some time, but we're already beginning to see the tide turning for certain stocks, including IonQ. The company's share price rose just 9% in 2025 -- compared to the S&P 500's gain of nearly 17%. If the economy slows down, you can expect investments in speculative corners of the market, including quantum computing, to slow as well. Investors have enjoyed great times in the market, partially thanks to artificial intelligence stocks. But if they catch wind of a recession or begin to worry that more layoffs are on the horizon, they'll likely flee to safer investments. Don't buy IonQ stock This quantum computing stock looks more like a gamble right now than a solid investment. IonQ's shares are too expensive, its losses are too wide, and the quantum computing market still has much to prove over the coming years. All of these reasons combined should point investors away from buying IonQ stock right now.Read NextJan 10, 2026 •By Keithen DruryCan $10,000 Invested in IonQ Transform Into $1 Million?Jan 10, 2026 •By Keith SpeightsThe Quantum Computing Stock Insiders Are Quietly BuyingJan 9, 2026 •By Sean WilliamsBeyond the Hype: 5 Reasons Quantum Computing Stocks IonQ, Rigetti Computing, and D-Wave Quantum Can Crash in 2026Jan 6, 2026 •By Justin PopeIs IonQ a Buy?Jan 6, 2026 •By Marc GubertiCan Pure-Play Quantum Stocks Really Make You $5 Million in 10 Years?Jan 3, 2026 •By Catie HoganIonQ Stock in 5 Years: Moon Shot or Crash Landing?About the AuthorChris Neiger has been a contributing Motley Fool technology and automotive analyst since 2012.
