D-Wave Quantum stock pops today as QBTS outperforms on year-end options buzz

NEW YORK, December 30, 2025, 1:03 PM ET — Regular session D-Wave Quantum Inc. shares climbed on Tuesday, extending a choppy year-end stretch for quantum-computing stocks as the group again outperformed a flat-to-weaker U.S. market. Reuters The move matters because quantum names have become a high-beta pocket of the tech market, with swings amplified by thin holiday liquidity and active retail trading. Investors.com said the group saw a late-December pop followed by profit-taking in the sessions that followed. Investors.com D-Wave has been one of the sector’s standout gainers in 2025, but the stock remains well off its highs, underscoring how

NEW YORK, December 30, 2025, 03:15 ET — Market closed Rigetti Computing, Inc. (RGTI) shares fell 0.49% to close at $22.27 on Monday and slipped 0.13% in after-hours trading to $22.24.

IonQ stock today: IONQ slips after hours as South Korea 100‑qubit deal hits tape

NEW YORK, December 29, 2025, 19:03 ET — After-hours IonQ, Inc. shares fell 1.6% to $45.25 in after-hours trading on Monday after the quantum computing company said it had finalized an agreement to deliver a 100‑qubit system to South Korea’s Korea Institute of Science and Technology Information (KISTI). IonQ Investors The announcement matters because investors have pushed quantum stocks around on thin evidence of near-term revenue. On-premises system deliveries tied to national research programs can offer clearer milestones than cloud-only access. IonQ said it will deliver a 100‑qubit “Tempo 100” quantum system and integrate it into KISTI‑6 (“HANGANG”), which it

NEW YORK, December 29, 2025, 11:49 ET — Regular session Rigetti Computing’s shares fell about 3% on Monday, extending a late-December pullback in quantum-computing stocks as traders booked gains and waited for fresh catalysts. The moves matter now because the quantum group has become a momentum trade into year-end, where lighter holiday liquidity can magnify swings in high-volatility names. Investors Business Daily said the sector’s recent slide followed a brief pop earlier this month that arrived “without major news,” and was later met by profit-taking and valuation jitters.

NEW YORK, December 29, 2025, 11:38 ET — Regular session Shares of IonQ Inc fell 1.7% to $45.22 in late-morning trading on Monday after the quantum computing company said it finalized an agreement with South Korea’s Korea Institute of Science and Technology Information (KISTI) to deliver a 100-qubit system.

Rigetti drops nearly 9% into year-end as quantum stocks cool — what investors watch next

NEW YORK, December 29, 2025, 03:12 ET — Market closed Rigetti Computing shares slid 8.7% on Friday, retreating with other quantum-computing “pure plays” in holiday-thinned trading. The stock closed at $22.38 and was last at $22.44 in extended trading, MarketBeat data showed. MarketBeat The pullback matters now because small-cap, high-beta stocks — shares that tend to swing more than the broader market — can move sharply when volumes are light and year-end positioning kicks in. That dynamic can amplify sector-wide moves even without fresh company news. Reuters+1 Investors are also looking ahead to the final trading days of 2025, when
