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 | IONQ Price Prediction) 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.
Rigetti reported Q4 2025 revenue of $1.868 million, missing consensus by 22%, and full-year revenue of $7.088 million, a 34% decline from 2024. CEO Subodh Kulkarni told investors the company anticipates “significant first-quarter year-over-year revenue growth” from Novera shipments, but the lumpy order pattern has weighed on sentiment.
The company holds $589.83 million in cash and investments, providing runway, and a 39% probability on Polymarket that the U.S. federal government takes a stake. That’s the highest of the three quantum names on that prediction market.
D-Wave: Strong Margins, Weak YTD Tape
D-Wave stock is changing hands near $23.77, up 10% on the day, the biggest single-session move of the three. Year to date, however, QBTS is down 9%, narrowly trailing Rigetti as the worst performer in the cohort.
D-Wave’s quantum annealing approach targets optimization problems rather than general-purpose computing. Q4 2025 revenue came in at $2.75 million, and full-year revenue grew 179% to $24.59 million with a GAAP gross margin of 83%. The bookings momentum is real, but the stock had run hard into year-end 2025, leaving plenty of room for a pullback.
Analyst sentiment remains constructive. The QBTS stock consensus price target sits at $35.77, with 13 buy ratings and 2 holds.
What to Watch
The takeaway: IonQ stock has dominated 2026 on the scoreboard, but the gap is narrowing fast on days like today. Quantum computing remains pre-profit and largely sentiment-driven, with milestone events, government contracts, and capital raises moving these stocks far more than fundamentals.
Reddit chatter has been actively comparing the trio, with one recent thread on r/stocks titled “Quantum Computing stocks: IONQ, RGTI, QBTS, QUBT” drawing fresh engagement. The bull case rests on fault-tolerant breakthroughs and growing enterprise interest. The bear case is that commercial quantum advantage timelines remain uncertain, and any name in the group can sell off sharply on a missed milestone.
Prudent investors weighing the space should keep an eye on whether today’s gains hold into the close, and watch for IonQ’s next earnings update for the next directional catalyst. For now, the YTD trophy belongs to IonQ, but the sector tape is moving as one.
