Quantum Computing 16 December 2025 - 23 December 2025

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.

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.

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.

It’s 5:45 a.m. ET on Thursday, December 18, 2025, and “quantum stocks” are waking up to a familiar push–pull: big long-term promises colliding with near-term market nerves about tech spending, rates, and whether the latest computing boom is getting ahead of itself. Reuters
