China’s largest homegrown DRAM chipmaker just got the green light for what could be one of the country’s most consequential tech IPOs in years. ChangXin Memory Technologies, or CXMT, has received approval from the Shanghai Stock Exchange to list on the STAR Market, targeting a raise of approximately 29.5 billion yuan, roughly $4.2 billion, through the issuance of 10.6 billion shares.
CXMT posted Q1 2026 revenue of 50.8 billion yuan, a more than sevenfold increase year-over-year. Profits jumped nearly 17-fold over the same period, powered by a global DRAM shortage that has lifted both memory chip prices and shipment volumes since mid-2025.
A state-backed challenger enters the ring
Headquartered in Hefei, CXMT has spent years trying to close the gap with the three companies that dominate the global DRAM market: Samsung, SK Hynix, and Micron. CXMT sits at the center of China’s push for chip self-sufficiency, receiving state support as the country tries to reduce its dependence on foreign memory suppliers.
Proceeds from the listing are earmarked for expanding DRAM production capacity, advancing manufacturing technology, and building out high-bandwidth memory capabilities. Specifically, CXMT is targeting mass production of HBM3 chips by 2026. HBM3 is the type of ultra-fast memory that powers AI training chips and high-performance computing systems.
