Chinese Chipmaker CXMT Soars on Shanghai Stock Exchange Debut

Full Summary — powered by AI

ChangXin Memory Technologies (CXMT), a leading Chinese memory chipmaker, experienced a significant surge in its stock price on its Shanghai Stock Exchange debut on July 27, 2026. Shares of CXMT, which specializes in DRAM memory chips, soared by 466% on the STAR market, reaching 49 yuan per share, up from its IPO price of 8.66 yuan. This impressive performance made CXMT China’s most valuable onshore-listed company, with a market capitalization reaching 3.3 trillion yuan ($488 billion) on its first day of trading.

The company’s initial public offering (IPO) raised at least $8.6 billion, marking it as mainland China’s second-largest IPO after the Agricultural Bank of China’s offering in 2010. CXMT’s success on the stock market reflects strong investor interest in semiconductor firms, particularly as China prioritizes self-sufficiency in advanced technologies amidst American-led restrictions on chipmaking equipment.

CXMT, established in 2016 in Hefei, is a major global producer of dynamic random-access memory (DRAM) chips, which are essential components in various electronic devices, including AI servers, smartphones, and computers. According to Counterpoint Research, CXMT was the world’s fourth-largest DRAM memory chipmaker by shipments in 2025, holding approximately 8% of the global market. The company’s revenue surged to 50.8 billion yuan ($7.5 billion) in the first three months of 2026, a more than 700% increase year-on-year, driven by the booming demand for artificial intelligence.
