If you want a single number that captures how badly investors want a piece of the AI chip boom, here it is: China’s ChangXin Memory Technologies, better known as CXMT, just ran an IPO whose retail tranche was oversubscribed nearly 244 times. The final winning rate landed around 0.47%, which is a polite way of saying that for roughly every 213 people who tried to buy in, one got shares and everyone else got a shrug.
The biggest Chinese chip listing in history
CXMT is raising about 57.9 billion yuan, roughly $8.6 billion, on Shanghai’s STAR Market, with a listing set for 27 July. That makes it the largest Chinese A-share semiconductor offering ever, bigger even than SMIC’s blockbuster 2020 debut, and Asia’s biggest IPO so far this year. Demand ran so hot the company doubled its original fundraising target. The reason is no mystery: CXMT makes DRAM, the memory chips that AI servers, data centres and every device you own devour by the billion, and the AI boom has turned memory into one of the tightest markets on the planet.
The bigger game underneath
This is also geopolitics wearing a prospectus. China has spent years trying to wean itself off foreign memory suppliers like Samsung, SK Hynix and Micron, and a homegrown DRAM champion flush with $8.6 billion of public money is precisely the sort of national-champion play Beijing has been building toward. US export controls choked China’s access to the best chipmaking gear; the response has been to pour capital into domestic capacity until the gap closes on its own. A wildly oversubscribed IPO is that strategy getting a very loud vote of confidence.
The market-watcher’s note (not investment advice)
Temper the euphoria with one boring fact: memory is the most brutally cyclical corner of the entire chip industry. Prices swing violently with supply, and today’s shortage is tomorrow’s glut. CXMT is listing at an elevated valuation just as some analysts warn the memory rally may be cracking, and a flood of new Chinese capacity could eventually push global prices down, including its own. A 244-times-oversubscribed IPO tells you how people feel today. It tells you almost nothing about what the chips will be worth in three years.
The AI tool stack actually worth paying for

Did you know: DRAM is so central to modern computing that its price swings have their own nickname among investors: the “memory cycle”. It has boomed and busted roughly every few years for decades, minting fortunes on the way up and vaporising them on the way down. Betting on memory is less like investing and more like surfing.
