The company holds a nearly eight per cent share of the global DRAM market, according to its fourth-quarter 2025 sales outlined in its initial public offering prospectus.State-backed CXMT’s primary competitors are South Korean and American tech giants that dominate the memory chip market. South Korea’s Samsung Electronics Co. Ltd. and SK Hynix Inc., alongside Micron Technology Inc. in the U.S., collectively hold about a 90 per cent share of the worldwide DRAM market.

Its IPO was 212 times oversubscribed, according to Bloomberg. The company’s market capitalization on Monday briefly surpassed that of Chinese internet giant and WeChat developer Tencent Holdings Ltd. Now valued at roughly US$490 billion, CXMT is the most valuable company listed in mainland China. (Tencent, valued at US$519 billion, is Hong Kong-listed).Founder Zhu’s net worth jumped 300 per cent to US$13.9 billion, according to the Bloomberg Billionaires Index. CXMT’s IPO is China’s largest since 2010 and Asia’s biggest of 2026.Counterpoint Technology Market Research Ltd. forecasts CXMT’s global market share to reach 11 per cent by 2028 from nine per cent in the first three months of the year. Morningstar Inc. estimates indicate that CXMT’s revenues will jump 405 per cent this year and 64 per cent in 2027.The stock was down about three per cent as of 2:31 pm in Shanghai on Tuesday, according to Bloomberg.

The U.S. is divided on how to manage the rise of CXMT, with some lawmakers and competitors such as Micron Technology Inc. seeking greater restrictions on the company’s access to advanced chipmaking equipment. The U.S. Pentagon has added CXMT to its 1260H list of blacklisted firms, designating it a Chinese military company, a charge which CXMT denies. Apple Inc. meanwhile is lobbying American officials to allow it to use memory chips from CXMT and another Chinese memory chipmaker, Yangtze Memory Technologies Co. Ltd., according to multiple media reports. The U.S. tech giant has already started testing CXMT’s memory chips for devices sold in China, according to a Financial Times report from earlier this month. China’s leading memory chipmaker CXMT soared 470 percent in its market debut in Shanghai on July 27, briefly surpassing megabank ICBC as the mainland’s most valuable company.

Investors will also encounter greater uncertainty regarding disclosures, board independence, influence of controlling shareholders or state-owned investors due to a different corporate governance landscape in China, Han said. According to CXMT’s IPO prospectus, state-owned shareholders owned 36 per cent of CXMT’s shares pre-IPO.“Investing in Chinese AI is not simply a bet on AI adoption. It is also a bet on China’s ability to build a competitive domestic semiconductor ecosystem while navigating a complex geopolitical environment,” Han said.Foreign investor access to CXMT shares is limited.Large institutional investors can access Shanghai A-shares through the Qualified Foreign Institutional Investor (QFII) program and can invest in Chinese technology enterprises through the Qualified Foreign Limited Partner (QFLP) scheme, Han said.Retail investors meanwhile can buy an exchange-traded fund (ETF) that owns CXMT. The Tema Memory ETF (DISK) added the Chinese chip company to its portfolio on Monday with a 10.56 per cent portfolio weight. “This position gives DISK the highest exposure to CXMT of any U.S.-listed ETF,” he said.A more likely route for Canadian retail investors is waiting for CXMT to become eligible for inclusion in the Shanghai-Hong Kong Stock Connect, which will allow international brokers to buy CXMT shares on behalf of foreign investors, Han said.
