- CXMT shares surged over 470% on debut at the Shanghai Stock Exchange's Star Market, pushing valuation to roughly 3.3 trillion yuan ($487.3bn) and making it the most valuable listed company in mainland China.
- The CXMT debut came despite a sharp global tech sell-off this month, offering some comfort to Chinese officials after a stock slump that wiped out more than $1.5tn from Chinese markets in recent weeks.
- CXMT manufactures DRAM chips for AI data centers, phones, PCs, and tablets; the firm was founded in 2016 by Chairman Zhu Yiming and is headquartered in Hefei, Anhui Province, with IPO proceeds earmarked for memory chip production and R&D.
- Anna Macdonald of Hargreaves Lansdown attributed the extraordinary bounce to the fact that only 7% of CXMT shares were available for trading — demand far outstripped supply.
- The DRAM market is dominated by Samsung Electronics, SK Hynix, and Micron, which together account for around 90% of global production — a duopoly-plus-one Beijing is trying to break.
- SK Hynix raised $26.5bn earlier this month in its New York share offering — the largest listing by a foreign firm in the US — selling 177.9 million ADRs at $149 each; shares surged 17% on Nasdaq debut but have since given back some gains.
Why it matters: Beijing gains a high-profile chip champion — CXMT is now China's most valuable listed firm — as it pursues tech self-reliance against the Samsung/SK Hynix/Micron oligopoly controlling 90% of global DRAM. But with only 7% of shares trading, much of the 470% surge reflects supply scarcity, not broad investor validation.
