CXMT Corp (688825) jumped 8.95% on Friday to close at 57.60 yuan (about $8.51), extending its rally through a fifth trading day on the Shanghai Stock Exchange.
The Chinese memory chipmaker has grown continuously in the few days since its record initial public offering (IPO) last week, pushing its market capitalization to roughly 3.54 trillion yuan, or about $523 billion.
Why CXMT Keeps Climbing
CXMT, short for ChangXin Memory Technologies, listed on Shanghai’s STAR Market on July 27. Shares surged as much as 466% on opening day. The move briefly pushed CXMT past Industrial and Commercial Bank of China to become mainland China’s most valuable listed company.
The IPO raised 57.92 billion yuan, or about $8.6 billion. CXMT plans to use the funds to expand production and close the technology gap with foreign rivals.
Two forces are driving investor demand. Beijing wants chip self-sufficiency as Washington restricts China’s access to advanced semiconductor equipment.
At the same time, a global shortage of dynamic random-access memory (DRAM), the chips that let devices and AI models store and process data, has manufacturers redirecting supply toward AI data centers.
What CXMT Actually Makes
CXMT was founded in 2016 and is based in Hefei. The company holds roughly 7.7% of the global DRAM market, making it the world’s fourth-largest producer. Samsung Electronics, SK Hynix, and Micron Technology control the other 90% between them.
CXMT mainly builds mainstream memory chips for phones, laptops, and servers. It still trails rivals in High Bandwidth Memory (HBM), the advanced chip type that feeds AI data centers directly. Counterpoint Research director MS Hwang said CXMT aims to start supplying HBM within China by 2027.
Dell, HP, and Apple have reportedly started testing CXMT’s chips as they look to diversify away from Korean and American suppliers. Price is the main draw. But the deal carries risk.
The Pentagon has added CXMT to a list of firms it links to the Chinese military, a designation the company denies. Apple is separately lobbying Washington for clearance to use Chinese-made memory.
CXMT’s rise lands amid what industry watchers call “RAMageddon,” a consumer device memory squeeze that has already boosted Apple’s smartphone pricing power and rattled chip stocks from Seoul to Wall Street.
Analysts remain split on how much relief CXMT can deliver. That means any pricing benefit for everyday devices probably won’t arrive soon, even as the AI chip race keeps accelerating.
