Yangtze Memory Technologies (YMTC), China's leading NAND flash memory manufacturer, has completed pre-IPO tutoring, clearing a crucial regulatory hurdle toward listing on Shanghai's STAR Market. The company is expected to submit its listing application imminently, with valuations potentially reaching 1 trillion yuan ($148 billion). YMTC is the world's third-largest NAND flash supplier and captured 14% of global market shipments in Q2 2026, surpassing Kioxia, Micron, and SanDisk.
The IPO follows CXMT's blockbuster listing last month, which raised $10 billion and set a template for China's memory champions. YMTC produces 267-layer 3D NAND using its proprietary Xtacking 4.0 architecture and is developing 300-layer-plus devices. The company operates two fabrication plants in Wuhan with combined monthly capacity of approximately 160,000 wafers, with a third phase expected to reach full production by end of 2026. However, YMTC remains constrained by its placement on the U.S. Commerce Department Entity List since 2022, limiting access to advanced lithography tools.
The IPO capital raise is critical for YMTC to increase exposure to high-margin enterprise SSDs, which now account for 48% of global NAND bits shipped (up from 26% year-over-year). As AI workloads shift from training to inference, inference requires larger KV caches and faster data access—making high-capacity enterprise storage increasingly valuable. For infrastructure buyers, YMTC's listing signals China's intent to establish a domestic NAND supply base independent of Samsung, SK Hynix, and Western Digital.
