NASDAQ:IONQ 15 November 2025 - 29 December 2025

NEW YORK, Dec. 28, 2025, 12:45 p.m. ET — Market closed. 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.

As of Sunday, December 21, 2025, quantum computing stocks are heading into one of the strangest trading stretches of the year: a holiday-shortened week with thinner liquidity, fewer scheduled catalysts, and a sector that can swing hard on a single analyst note. That’s a big deal for investors tracking IonQ, D-Wave Quantum, Rigetti Computing and Quantum Computing Inc.—a group often dubbed the “pure-play” quantum cohort—because the last few days brought something the space has been craving: more formal Wall Street coverage, clearer price targets, and more structured debates about which business models may actually scale.

U.S.-listed quantum computing stocks are back in focus in Friday’s premarket session as traders digest a burst of company-specific headlines—new contracts and partnerships, an M&A-driven photonics land grab, and a new wave of Wall Street coverage that’s putting ambitious 2026 price targets on some of the market’s most volatile tech names. The result: familiar tickers—IonQ, D-Wave Quantum, Rigetti Computing and Quantum Computing Inc.—are seeing early moves as investors weigh near-term catalysts against the longer-term question that still defines the entire theme: How fast can “quantum promise” turn into durable, recurring revenue?

NEW YORK — December 18, 2025 — Quantum computing stocks on U.S. markets are attempting a bounce Thursday after a sharp, sentiment-driven pullback that hit high-beta tech names. As of the latest available pricing near midday, the four U.S.-listed “pure-play” quantum names are all higher on the session, with traders reacting to a mix of partnership news, M&A headlines, and fresh analyst coverage that frames quantum as a long-duration “compute” theme tied to the AI buildout. At the same time, today’s coverage makes clear the debate is still wide open: bulls argue quantum becomes a meaningful slice of future compute spending, while skeptics point to thin current revenues, high valuations, and the sector’s tendency to move violently on headlines.
