China's CXMT secures strong IPO demand despite semiconductor market slump

While China's premier memory chipmaker, ChangXin Memory Technologies (CXMT), is moving forward with its massive $8.6 billion initial public offering (IPO) on Shanghai’s tech-heavy STAR Market, a global cooldown in semiconductor stocks has tempered investor enthusiasm.

As reported by Reuters, CXMT is still attracted exceptionally strong institutional interest for its $8.6 billion Shanghai IPO, but demand was weaker than many investors had expected because of a broad selloff in Chinese semiconductor stocks.

According to a company filing on Sunday, July 19, 2026, institutional interest remains intact but noticeably lacks the frenzied momentum seen in past flagship Chinese tech debuts.

Sunday's announcement came days after CXMT said the retail portion of its IPO was 243.93 times oversubscribed, also pointing to less investor fervour.

The institutional investors including mutual funds, pension funds, and insurers subscribed for 1.24 trillion shares compared to the 2.17 billion shares on offer. This translates to being ~570 times oversubscribed.

In a statement on Sunday, CXMT, China's top memory chipmaker, said institutional investors including mutual funds, pension funds and insurers subscribed for a total of 1.24 trillion shares, compared with 2.17 billion IPO shares on offer to them.

That translates into an oversubscription ratio of roughly 570 times. The multiple points to solid demand, but is much smaller than in recent STAR Market IPOs.

CXMT's IPO, Asia's biggest so far ‌this year, comes amid a brutal sell-off in once high-flying chip stocks as investors from Seoul to Silicon Valley start asking whether the AI boom became over-leveraged and got ahead of itself.

In China, the STAR Market, home to many leading chip stocks, has plunged roughly 25% from its July 1 peak, wiping out over 4 trillion yuan ($590.32 billion) of market value.

The AI boom has boosted demand for DRAM, or dynamic random-access memory chips, which are used in smartphones, computers, servers and other electronics.

CXMT, the world's fourth-biggest DRAM chipmaker after Samsung, SK Hynix and Micron Technology has not disclosed when it will list on the STAR Market while sources informed the ⁠stock ​will debut on July 27.
