CXMT's $8.6B IPO Sees 570x Institutional Oversubscription, Below Recent STAR Market Peers
Miles Bennett
China's largest memory-chip maker CXMT drew over 570x institutional oversubscription for its STAR Board IPO — but that figure trails recent peers on the same exchange by nearly an order of magnitude, as a global chip selloff weighs on appetite for Asia's biggest listing this year.
570x sounds huge — why is this called "cool"?
Institutional investors — mutual funds, pensions, insurers — bid for roughly 1.24 trillion shares. Only about 2.17 billion shares were on offer, yielding ~570x oversubscription.
Recent STAR Board IPOs — Zhuhai Trinomab (688806), Chongqing Genor (688797), Wuhan Changjin Photon (688635) — all topped 5,000x institutional oversubscription.
This means → 570x is respectable in absolute terms, but against the STAR Board's recent "new-listing frenzy," it is less than one-ninth the heat of comparable deals.
Retail oversubscription came in at 243.93x, also below expectations. Both institutional and retail demand cooled in tandem.
Why did this particular IPO hit a cold patch?
The pricing window coincided with a global re-rating of chip stocks. From Seoul to Silicon Valley, investors are questioning whether the AI boom has run ahead of fundamentals.
The STAR Board chip index (CSI000680) has fallen roughly 25% from its July 1 peak, erasing over ¥4 trillion (~$590.3 billion) in market value.
In plain terms = the entire chip sector just went through a de-foaming cycle. Risk appetite is contracting, and an $8.6 billion mega-IPO landing in the middle of that contraction naturally draws caution.
Who exactly is CXMT?
The world's fourth-largest DRAM (dynamic random-access memory — the most common memory chip in phones, PCs, and servers) maker, behind Samsung, SK Hynix, and Micron.
Expanding AI compute is a core demand driver for DRAM — each AI server requires far more memory than a conventional one.
This reflects a company whose industry standing and growth thesis are intact. The issue is timing and sentiment, not fundamentals.
What comes next?
Reuters, citing people familiar with the matter, reports CXMT is expected to begin trading on the STAR Board on July 27. The company has not officially confirmed the date.
This means → the first-day performance will serve as a barometer for two things: whether the market accepts CXMT's own valuation, and how it anchors pricing for the pipeline of high-profile tech IPOs Beijing is pushing under its self-reliance agenda.
In plain terms = if CXMT's debut is tepid, other tech companies in the listing queue may have to lower their pricing expectations.
