Rigetti stock slips as quantum trade cools into year-end — what investors watch next

NEW YORK, December 29, 2025, 12:48 ET — Regular session Rigetti Computing shares fell about 2.1% to $21.92 in midday trading on Monday, after closing at $22.38 on Friday. The decline highlights how quickly sentiment can shift in the small group of “pure-play” quantum-computing stocks as the year ends. Profit-taking and thin holiday liquidity have amplified swings in the sector, Investors.com reported. Investors Moves across the group were mixed. IonQ fell about 2.3% while D-Wave Quantum rose about 0.6%, and Quantum Computing Inc slid about 2.3%. Quantum-computing shares jumped on Dec. 22 without major company news and then sold off

IonQ stock slips as Korea’s KISTI finalizes 100-qubit quantum system deal

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. IonQ Investors The announcement matters because hardware deliveries are a visible test of whether quantum-computing developers can turn research partnerships into paid deployments of machines that cost far more than typical cloud subscriptions. IonQ is one of a small set of U.S.-listed pure plays that can swing sharply on contract headlines.

The stock closed at $22.38 and was last at $22.44 in extended trading, MarketBeat data showed.

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.

The move matters now because year-end trading tends to magnify swings in high-volatility stocks, while investors reassess crowded themes ahead of 2026.
