Quantum IPO Stock Loses 200 Billion Won in Market Cap in Just One Day

Infleqtion Inc. (INFQ) tumbled 7.61% to close at $9.83 (approximately ₩14,000) on the New York Stock Exchange on the 26th (local time). Its market capitalization shrank to about $2.13 billion (roughly ₩3.1 trillion), erasing nearly $150 million (around ₩220 billion) in a single session. Trading volume exceeded 1.9 million shares, underscoring the stock’s early-stage volatility.

The company went public on February 17 through a merger with the SPAC Churchill Capital Corp. X, becoming the first neutral-atom-based quantum computing firm to list on the NYSE and raising more than $550 million (about ₩790 billion). In March, Infleqtion delivered a 100-qubit quantum computer called “Sqale” to the U.K.’s National Quantum Computing Centre and was selected for a $3.9 million (approximately ₩5.7 billion) award under a U.S. federal next-generation chemistry and materials research program, among other technology and government partnerships.

Originally known as ColdQuanta, Infleqtion is a U.S. quantum-technology company that has developed neutral-atom-based quantum computing, quantum sensing, and precision timekeeping technologies. It integrates its hardware—quantum computers, sensors, and optical clocks—with its software platform, SuperstaQ, and counts the U.S. Department of Defense, NASA, the U.K. government, and NVIDIA among its project partners. With growing commercial revenues, Infleqtion stands out among publicly traded quantum stocks for its real-world deployments.
