❯ CXMT Overtakes Tencent to Top China Market Cap 17 Days After Listing

FIRST-EVERMemory chipmaker ChangXin Memory Technologies (CXMT) reached a market cap of $524 billion, surpassing Tencent’s $511 billion and claiming the No. 1 spot in China just 17 days after listing—the first time in 35 years of mainland China’s stock market that a semiconductor company has taken the top seat.

IPO FRENZYThe company listed in Shanghai on July 27, raising $8.6 billion, with retail subscriptions oversubscribed more than 212 times and a first-day surge of 466%. CXMT is the world’s fourth-largest DRAM maker, behind SK Hynix, Samsung, and Micron. It plans to build a sixth major fab and aims for 30% of global DRAM share by 2030.

SHIFTThe other half of the overtaking story is Tencent: its Q2 report showed capital spending on AI infrastructure surged 176%, sending the stock lower. For the same AI spend, the market is pricing chip sellers and chip buyers in opposite directions—in the memory up-cycle, profits are moving upstream, and A-share investors have voted with real money.

VALUATIONThe hard question is ahead: a $524 billion market cap still corresponds to a catch-up player’s capacity and technology gap. Once the memory cycle peaks, CXMT’s share price will have to be supported by progress toward that 30% share goal by 2030, and the valuation ceiling for A-share semiconductor names will rise and fall with it.

▪ SIGNALChina’s No. 1 market cap has shifted from a platform company to a memory maker, as capital’s AI pricing focus moves from the application layer to physical capacity.
