China's memory chip leader, Cxmt Corporation, made a spectacular debut on the A-share market, creating a new variable in the global memory chip sector.
During Monday's US trading session, memory chip stocks tumbled, becoming the biggest drag on the broader market. SanDisk Corp. (SNDK) fell over 10% intraday, hitting a fresh daily low with a decline of about 14.6%, and has dropped 47% from its all-time high on June 22, with its market value evaporating by approximately $170 billion over the past month. SK Hynix ADR (SKHY) fell about 10% during the session, while Western Digital (WDC) and Seagate Technology (STX) saw declines of over 9% and 8%, respectively, and Micron Technology (MU) was down more than 7% at one point.
At its intraday low, the Philadelphia Semiconductor Index, which tracks the overall performance of chip stocks, fell about 5%, significantly underperforming the three major US stock indexes. The S&P 500 and Nasdaq hit fresh daily lows with declines of about 0.4% and 0.8%, respectively, while the Dow Jones Industrial Average maintained its gains throughout the day.
Market participants widely attribute the sell-off to the listing of Cxmt Corporation (688825) on the Shanghai Stock Exchange's STAR Market. China's largest DRAM manufacturer saw its stock price surge over 460% on its first day of trading, pushing its market capitalization beyond 3 trillion yuan, making it the new heavyweight on the A-share market and prompting global investors to reassess the competitive landscape of the DRAM industry in the coming years.
China's DRAM Leader's IPO Triggers a Global Storage Sector Re-evaluation
Regarding the sharp decline in US memory chip stocks on Monday, multiple foreign media outlets suggest that the market's concern is not about Cxmt Corporation's short-term performance, but the potential future changes in the global DRAM supply landscape.
Analysts believe that after completing Asia's largest IPO so far this year, Cxmt Corporation will have more ample capital support. This is expected to enhance its future capacity expansion, technology research and development, and its ability to move into high-end AI storage fields like HBM. For global memory chip leaders that have already seen significant price increases, this signals rising long-term competitive pressure.
Some commentators point out that the market fears the completion of Cxmt Corporation's fundraising could accelerate the release of new DRAM supply, potentially weakening the current optimistic outlook for sustained memory price increases. Meanwhile, Micron Technology, SK Hynix, and SanDisk Corp. have experienced substantial rallies, making them vulnerable to profit-taking at high valuations in response to any changes in the competitive landscape.
Other commentators believe this correction is more about market repricing. While AI-driven demand for HBM remains robust, investors are beginning to reconsider: if Chinese manufacturers continue to enhance their production capacity and technological capabilities, will the traditional DRAM business enter an intensified competition phase earlier than expected, thereby impacting industry profit margins?
However, many analysts argue that the market reaction may be somewhat overblown.
Currently, Cxmt Corporation's products are primarily focused on traditional DRAM areas like DDR4 and DDR5. In contrast, the fastest-growing profit segments for Micron Technology, SK Hynix, and Samsung come from AI storage products like HBM. Due to US export restrictions, Cxmt Corporation still faces high technical barriers to entering the high-end HBM market in the short term, meaning the global AI memory market landscape is unlikely to undergo a fundamental change soon.
Cxmt Corporation's Soaring Debut: Capital Markets Bet on 'China Storage'
Cxmt Corporation's IPO itself has already drawn global attention.
The company raised approximately 57.9 billion yuan (about $8.6 billion) in this offering, setting a new record for the largest IPO in Asia this year. On its first day of trading Monday, the stock closed 465.82% above its issue price, giving it a total market capitalization of 3.28 trillion yuan. This surpasses Industrial and Commercial Bank of China to become the highest-valued stock on the A-share market, with a market cap equivalent to two Kweichow Moutai.
On Monday, the trading volume for Cxmt Corporation exceeded 140 billion yuan, making it the first individual stock in A-share history to surpass a daily trading volume of 100 billion yuan.
Public information shows that Cxmt Corporation, founded in 2016, is China's largest DRAM chip manufacturer and a key representative enterprise for China's independent DRAM research, development, and mass production. The company's products currently cover areas including consumer electronics, PCs, servers, and automotive electronics, and it continues to advance the development of new products like DDR5.
Domestic media generally view the listing of Cxmt Corporation not only as a new milestone for China's semiconductor industry but also as a sign that the capital market is assigning a higher valuation premium to domestic high-end manufacturing and "hard technology." The market expects the raised funds will further support advanced process R&D, capacity expansion, and the improvement of the domestic memory supply chain.
In the AI Era, HBM Remains the True Decisive Factor
However, from a global competitive perspective, most institutions still believe that the leading positions of Micron Technology, SK Hynix, and Samsung in the AI memory space are unlikely to be challenged in the short term.
The current explosion in demand for AI servers has made HBM one of the most sought-after semiconductor products globally. Micron Technology and SK Hynix essentially dominate the HBM supply for AI chip makers like Nvidia, and this business is a core driver of their rapid profit growth.
Therefore, many analysts believe Monday's sharp decline in memory stocks was more of a sentiment-driven valuation adjustment rather than a change in the industry's fundamentals. As AI infrastructure construction continues to advance, demand for high-end memory is expected to maintain strong growth.
Bernstein analyst Mark Li even suggested that the sector's pullback that day actually provided a new opportunity for positioning. He forecasts that by 2027 to 2028, the global memory chip market revenue could still exceed $1.3 trillion, with data center construction in the AI era continuing to support demand growth for DRAM and HBM.
