CXMT IPO Sparks Liquidity Siphoning Concerns
0xBroomberg
CXMT lists on Shanghai's STAR Market on July 27, raising roughly $8.6 billion in Asia's largest IPO this year; pre-listing repositioning has already dragged the STAR 50 index down nearly 20% this quarter, stoking fears that mega-IPOs are reshaping supply-demand dynamics for China tech stocks.
The stock hasn't listed yet — why is the market already falling?
The market expects CXMT's post-listing valuation to quickly top ¥1 trillion (about $139 billion), making it a dominant weight in the STAR Market and semiconductor indices.
This means → index funds, active funds, and sector-theme funds must rebalance toward CXMT ahead of time — effectively forced to sell existing memory-chip, equipment, and domestic-substitution holdings first.
In plain terms = before a single share trades, the mere expectation of "it's coming" has forced the entire sector to reshuffle. The STAR 50 index is down nearly 20% this quarter, and this pre-positioning is a direct driver.
Is the IPO the real reason for the sell-off?
Multiple analysts are clear: the IPO is an "amplifier" of the current correction, not its root cause.
Tim Sun, senior researcher at HashKey Group, argues that crowded positioning and elevated leverage in A-share tech are the core issues; a sell-off in Korean chip stocks transmitted pressure to global semiconductor valuations and triggered profit-taking in China.
Benjamin Cavender, managing director at CMR Consulting, puts it more bluntly: CXMT is "a catalyst that concentrated existing worries," not the original trigger for selling.
Why is the Chinese market especially sensitive to mega-IPOs?
China's stock market is dominated by retail investors — roughly 90% of daily turnover, according to HSBC data.
IPO shares are allocated through a lottery-style system: the larger an investor's subscription, the higher the odds of winning an allotment. Retail investors tend to sell existing holdings to fund subscriptions.
This means → every mega-IPO triggers a round of "cash calls" — not institutional strategic rebalancing, but a mass of retail investors selling stocks for cash simultaneously, amplifying the liquidity shock.
Will the impact be short-lived or lasting?
Cavender expects capital to flow back once allotment is complete and trading begins; the direct liquidity hit should be brief.
Peter Alexander, founder of Z-Ben Advisors, likewise expects a "notable pop" on listing day, followed by a new market equilibrium.
But Cavender warns: if the market concludes it must keep absorbing a pipeline of mega-IPOs in semiconductors, AI, and national-strategy companies, the effect could prove more durable. In plain terms = the issue is not one IPO permanently draining cash — it is that a steady stream of giants reshapes the supply-demand balance for high-growth Chinese tech stocks, forcing existing capital to keep reshuffling.
What do CXMT's own fundamentals look like?
CXMT is China's largest DRAM manufacturer — DRAM being the memory chips most commonly used in phones and computers. Its global market share reached 7.67% in Q4 2025, ranking fourth worldwide.
The company disclosed projected H1 2026 revenue of ¥110–120 billion and net profit of ¥50–57 billion, compared with full-year 2025 net profit of just ¥1.875 billion.
This means → the explosive profit jump reflects a tight global DRAM supply-demand balance and a concentrated up-cycle in memory-chip pricing. Counterpoint Research believes the IPO proceeds will accelerate capacity expansion and strengthen CXMT's competitive standing globally.
