Small-Cap Stocks Quiet Early, Surge 7% in Final Minutes Driven by Quantum Computing

Quantum Computing Inc. (NASDAQ: QUBT), a small-cap quantum computing stock, jumped 7.19% on the 13th (U.S. time), closing at $12.51. Its market capitalization swelled to about $2.8 billion (roughly ₩3.7 trillion), adding—rather than losing—some $217.2 million (around ₩290 billion) in a single day. Trading volume also surged past 12.99 million shares, reflecting strong demand at the close.

According to recent filings, Quantum Computing has been rolling out ongoing technology and business updates for its quantum software platform, focusing on expanding pilot projects and partnerships with government agencies and corporate clients. At the same time, heightened short-term volatility has underscored a pattern of daily price swings driven by profit-taking and short-covering.

Headquartered in Virginia, U.S., Quantum Computing is a quantum software and solutions provider that develops optimization and machine-learning algorithms and platforms compatible with early-stage quantum hardware. While its revenues remain modest given the pre-commercial phase of quantum computing, it is widely regarded as a prototypical small-cap beneficiary of the “theme premium,” buoyed by expectations around the global technology race and defense and security applications.
