Chinese memory chip manufacturer CXMT Corp (688825.SS) began trading on the Shanghai Stock Exchange on Monday, July 27, in what is Asia's biggest initial public offering of 2026. The company raised 57.92 billion yuan ($8.6 billion) by selling 6.69 billion shares at 8.66 yuan each, and instantly became China's largest listed company by market capitalization.
CXMT — formerly known as ChangXin Memory Technologies — manufactures DRAM chips used in computers, smartphones, servers, and artificial intelligence systems. The blockbuster IPO underscores Beijing's state-led push to channel public capital into technology champions as China races toward semiconductor and AI self-sufficiency amid escalating U.S.-led export controls.
Proceeds from the offering could rise to 66.61 billion yuan ($9.8 billion) if underwriters fully exercise an over-allotment (greenshoe) option. The company plans to use the funds for chip production capacity expansion, research and development, and working capital.
The listing arrives at a pivotal moment for global memory markets. CXMT's emergence as a publicly traded powerhouse directly challenges the long-standing dominance of South Korea's Samsung Electronics and SK Hynix — both of which recently announced massive AI chip partnerships with Nvidia and Broadcom.
"CXMT's mega IPO signals 'China Shock 3.0' in the memory sector," said Peter Alexander of Z-Ben Advisors on CNBC. Analysts noted that CXMT's DRAM market share has grown to 7.67%, up from near zero just five years ago, as the company rapidly scales production of DDR5 and HBM (high-bandwidth memory) chips critical for AI workloads.
Eugene Hsiao of Macquarie Capital told CNBC the IPO represents a major milestone for both China's tech self-sufficiency drive and the global memory industry's restructuring. The company's dominant market cap position signals strong investor confidence in China's ability to develop independent semiconductor capabilities.
