Quantum Computing Stocks Surge 14%... Market Cap Increases by 1 Trillion Won in One Day

Infleqtion Inc. (NYSE: INFQ), a U.S. quantum technology company, surged more than 14% on June 2, closing at $20.19 on the New York Stock Exchange. Trading volume topped 17.67 million shares, lifting its market capitalization to about $4.4 billion (roughly KRW 6 trillion)—an intraday increase estimated at $720 million (nearly KRW 1 trillion).

This week’s rally follows news that Infleqtion has opened a Quantum Innovation Hub in Oxford, U.K., to expand its neutral-atom platform and deepen partnerships with national initiatives such as the U.K. National Quantum Computing Centre and Quantum Fridge 2026. Investor enthusiasm was further fueled by a letter of intent with the U.S. Department of Commerce for up to $100 million in CHIPS Act funding, and by record first-quarter revenue of $9.5 million (approximately KRW 13 billion), a 14% increase year-over-year.

Infleqtion is a leading developer and commercializer of neutral-atom–based quantum technologies—including quantum computing, sensing, precision timing, and RF receivers—serving government, corporate, and research clients across North America, Europe, and Asia. Founded in 2005 as ColdQuanta and rebranded as Infleqtion, the company went public on the NYSE in February and is now recognized as one of the few pure-play quantum computing stocks.
