D-Wave stock slides into year-end as quantum peers retreat in thin trade

D-Wave stock slides into year-end as quantum peers retreat in thin trade

NEW YORK, December 29, 2025, 02:54 ET — Market closed. D-Wave Quantum Inc shares were last down 8.1% at $25.29, extending a late-week pullback in U.S.-listed quantum-computing names. The move matters because the final trading days of the year often come with thinner liquidity, which can amplify swings in volatile, high-momentum stocks. That can leave price action looking dramatic even when the broader market backdrop is relatively calm. Reuters U.S. stocks ended nearly flat in a light post-Christmas session on Friday, Reuters reported. Ryan Detrick, chief market strategist at Carson Group, said the market was “catching our breath” after a

Rigetti stock drops nearly 9% as quantum names cool into year-end

NEW YORK, December 28, 2025, 21:47 ET — Market closed Rigetti Computing shares slid 8.6% to $22.38 in Friday’s regular session, retreating as quantum-computing stocks pulled back into the final week of the year. The move matters now because year-end trading tends to magnify swings in high-volatility stocks, while investors reassess crowded themes ahead of 2026. Reuters described Friday’s broader tape as light-volume and catalyst-thin, a backdrop that can sharpen moves in speculative corners of the market. Reuters Other “pure-play” quantum names fell in tandem. IonQ dropped about 7.6%, D-Wave Quantum slid about 8.1% and Quantum Computing Inc fell about

IonQ drops with quantum peers into year-end, as investors weigh next catalysts

NEW YORK, December 28, 2025, 9:31 PM ET — Market closed IonQ shares fell 7.6% to $46.00 in their last U.S. session on Friday, retreating with other quantum-computing stocks into the final days of the year. The move matters because IonQ is one of a small set of publicly traded “pure plays” in quantum computing — companies whose main business is building quantum hardware and services — and the group has been prone to sharp swings on relatively little news. Reuters With the sector still early in commercial adoption, traders have been treating customer deals and roadmaps as key markers

Quantum Computing Stocks: IonQ, Rigetti, D-Wave and QUBT Slide Into Year-End—What to Watch Before Monday’s Open

NEW YORK, Dec. 28, 2025, 12:45 p.m. ET — Market closed (Weekend). Quantum computing stocks are heading into the final trading week of the year with a familiar mix of promise and turbulence—exactly the kind of setup that can amplify both opportunity and risk when liquidity is thin. In the most recent regular session (Friday), several of the best-known “pure-play” quantum names posted sharp declines even as the broader U.S. market largely drifted in quiet, post-holiday trade. IonQ (IONQ) finished at $46.00, down about 7.6%. Rigetti Computing (RGTI) closed at $22.38, down roughly 8.6%. D-Wave Quantum (QBTS) ended at $25.29,

NEW YORK, Dec. 28, 2025, 4:45 a.m. ET — Market Closed Quantum Computing Inc. (Nasdaq: QUBT) heads into the final full trading week of 2025 with investors digesting a sharp Friday pullback, fresh sector-wide commentary, and a mixed set of Wall Street price targets that underscore just how split the market remains on “pure-play” quantum names. With U.S. exchanges closed for the weekend, QUBT won’t print another official quote until Monday’s session. But the setup is already clear: this is still a high-volatility stock sitting at the intersection of big-tech-level ambition (quantum + photonics) and early-stage financial reality (small revenues,

NEW YORK, Dec. 28, 2025, 4:16 a.m. ET — Market closed (weekend) IonQ, Inc. (NYSE: IONQ) is heading into the final trading days of 2025 with traders arguing two opposite things at the same time: that quantum computing could be the next platform shift in tech—and that today’s pure-play quantum stocks can still swing wildly on thin liquidity, valuation debates, and headline-driven momentum.
