China’s leading dynamic random access memory (DRAM) chipmaker ChangXin Memory Technologies (CXMT) said on Tuesday it plans to raise 29.5 billion yuan ($4.22 billion) through an initial public offering in Shanghai, as it seeks to expand production and narrow the gap with global rivals.
According to its prospectus, CXMT will issue 10.6 billion shares, with proceeds earmarked primarily for upgrading production lines, improving manufacturing technologies and boosting research and development of advanced DRAM products. The listing follows the company’s unveiling last month of its latest DDR5 DRAM chips, directly challenging established competitors in South Korea and the United States.
Founded in 2016 with strong state backing, CXMT has become a cornerstone of China’s ambition to build a domestic memory chip industry. The global DRAM market is currently dominated by Samsung Electronics, SK Hynix and Micron Technology, which together control more than 90% of the market. CXMT held around a 4% global market share in the second quarter, according to data from Omdia cited in the prospectus.
The company operates three 12-inch DRAM fabrication plants in Beijing and at its headquarters in Hefei, Anhui province. After nine funding rounds, CXMT counts major Chinese investors such as Alibaba and Xiaomi, and has developed four generations of DRAM technology.
CXMT is also investing heavily in high-bandwidth memory (HBM), a specialised form of DRAM essential for advanced processors such as Nvidia’s graphics processing units used in generative AI. The company plans to begin HBM production by the end of 2026 at a back-end packaging facility under construction in Shanghai.
Financially, CXMT expects strong growth. It projects revenue could rise by as much as 140% year-on-year in 2025, driven by higher memory prices and increased sales volumes since July. While the company has posted heavy losses in recent years, it said it could turn profitable as early as 2026, depending on wafer shipments and average selling prices. CXMT reported losses of 8.32 billion yuan in 2022, 16.3 billion yuan in 2023 and 7.1 billion yuan in 2024, and recorded a 2.3-billion-yuan loss in the first half of this year.
