World's No. 4 DRAM Maker CXMT Launches STAR Market IPO

ChangXin Memory Technologies, or CXMT, is a Chinese memory-chip giant seen as central to the country’s push for semiconductor self-sufficiency and a domestic supply chain as the artificial intelligence boom fuels demand for high-bandwidth memory, or HBM. Its development has implications beyond its own operations, directly affecting the reshaping of the global semiconductor industry and the sensitive U.S.-China technology rivalry. The company has therefore drawn intense attention from markets and investors.

CXMT launched a $9.8 billion initial public offering on July 18, 2026, the second-largest listing in Chinese history, with the retail tranche 212 times oversubscribed. The scale of the fundraising rattled markets, sending South Korean rival SK Hynix’s ADR down 13% and memory-chip stocks tumbling worldwide. Meanwhile, futures contracts linked to CXMT had already surged on Hyperliquid’s blockchain-based derivatives market.

The adoption of generative AI and expansion of AI data centers have driven a surge in demand for high-bandwidth memory (HBM). Samsung Electronics, SK hynix and Micron have shifted more capacity to HBM, squeezing the supply of general-purpose DRAM. The resulting shortages have displaced price competition and changed the pricing flexibility available to Chinese memory producers.

Information compiled as of July 20, 2026, showed that ChangXin Memory Technologies’ DRAM prices were now close to those of the world’s three largest suppliers. The company has therefore abandoned steep discounts as a way to gain market share, instead raising quotes in line with supply and demand to maximize profits. Reports did not disclose actual prices by product capacity or the dates and scale of the adjustments. The key signal is a clear shift away from low-price strategies among Chinese suppliers.
