Is IonQ the Top Quantum Computing Stock to Buy Right Now?
By Keithen Drury – Feb 3, 2026 at 12:22AM ESTKey PointsIonQ is leading the way in quantum computing accuracy. There is still plenty of time for other companies developing their own versions of the technology to catch up. NYSE: IONQIonQMarket Cap$14BToday's Changeangle-down(-3.55%) $1.42Current Price$38.56Price as of February 2, 2026 at 4:00 PM ETIonQ currently has the most accurate quantum computing solution based on one key metric.The level of hype around quantum computing seems to cycle up and down. For example, excitement about it surged to peaks during December 2024 and October 2025, but lately, it has significantly declined. While the nascent technology and the companies attempting to bring it to market are still on some investors' radar, they have fallen entirely off of most people's. That could make now a prime opportunity to buy some quantum computing stocks at lower prices, and that's exactly what I did. After missing some of IonQ's (IONQ 3.55%) major rises in 2025, I recently bought its shares, which are now down by more than 50% from their high. I think it's a great option in the quantum computing space, but is it the top buy overall? Image source: Getty Images. IonQ's fidelity advantage The quantum computing field is filled with competitors, large and small. IonQ is among the smaller pure-play upstarts with relatively few resources that are looking to become major players. But many giant tech companies with nearly unlimited resources to devote to R&D are also competing in the quantum computing realm, as this new technology could bolster their already formidable capabilities. There are viable competitors across the size spectrum, but the reality is, we're a long way off from knowing which ones will eventually be the winners.
