Which Quantum Computing Stock Has Dominated in 2026: IonQ, Rigetti, or D-Wave? David Moadel Wed, May 6, 2026 at 3:29 PM EDT 4 min read IONQ +15.32% QBTS +7.22% RGTI +7.46% Quick Read IonQ (IONQ) is the only pure-play quantum computing stock with positive year-to-date returns at +16%, having posted Q4 2025 revenue of $61.89M (beating consensus by 54%) and becoming the first public quantum company with over $100M in GAAP revenue. Rigetti Computing (RGTI) is down 10% YTD after missing Q4 revenue by 22%, and D-Wave Quantum (QBTS) is down 9% YTD despite posting an 83% GAAP gross margin. IonQ’s trapped-ion technology, cloud distribution partnerships, and pending SkyWater foundry acquisition have insulated it from some of the volatility hitting smaller quantum competitors still relying on single milestones.

Quantum computing stocks are surging across the board this afternoon, with all three pure-play names rallying in midday trading. The move has reignited a debate that's defined the sector all year. Which quantum name has actually delivered for shareholders in 2026? The answer, at least through the May 5 close, is clear. IonQ (NYSE:IONQ) is the only one of the three pure-play quantum computing stocks holding a positive year-to-date (YTD) return, while Rigetti Computing (NASDAQ:RGTI) and D-Wave Quantum (NYSE:QBTS) are essentially tied as laggards.

Today's rally is broad and sentiment-driven, but the year-to-date scoreboard tells a more selective story. Here's how the three stack up heading into the close. For broader context on the sector, see our recent coverage of the 2026 outlook for quantum computing stocks. IonQ: The Clear YTD Leader IonQ stock is trading at around $5250 intraday on May 6, up 9% on the day, extending what's already been a strong year. Shares are up 16% year to date, the only positive return among the three pure-play quantum names. The fundamental case has matched the price action. IonQ posted Q4 2025 revenue of $61.89 million, beating consensus by 54%, and became the first public quantum company in history with more than $100 million in GAAP revenue. Management is guiding to $225 million to $245 million in revenue for 2026. IonQ's $19.43 billion market cap gives it a more institutional-grade trading profile than the company's peers. Trapped-ion technology, hyperscaler cloud distribution, and the pending SkyWater Technology acquisition have insulated it from the single-milestone volatility hitting smaller rivals. Rigetti: Down on Revenue Execution Rigetti shares are trading near $19.90, up 9% on the day, but the stock is down 10% year to date. The superconducting qubit specialist has lagged on commercial traction. Story Continues View Comments Terms and Privacy Policy Privacy Dashboard
