China's DRAM giant disrupts global dynamics; CXMT's debut soars sky-high, US memory chip stocks plunge collectively.

```

The explosive debut of the leading Chinese memory chip maker CXMT on its first day on the A-share market is becoming a new variable in the global memory chip sector.

During Monday's U.S. trading session, memory chip stocks plunged, dragging down the market the most. SanDisk (SNDK) fell more than 10% intraday, hitting a new daily low in the morning with a drop of about 14.6%; SK Hynix ADR (SKHY) once fell about 10% intraday; Western Digital (WDC) and Seagate Technology (STX) both fell more than 9% and 8% intraday, respectively; Micron Technology (MU) once fell more than 7%.

When it hit the daily low in the morning, the Philadelphia Semiconductor Index, tracking overall chip stock performance, fell about 5%, far underperforming the three major U.S. stock indexes. When the S&P 500 Index and Nasdaq hit their daily lows, they were only down about 0.4% and 0.8%, respectively, while the Dow held gains throughout the day.

The market broadly pointed the finger at CXMT (Changxin Memory Technologies), which was listed on the SSE STAR Market that day. The share price of China's largest DRAM manufacturer soared more than 460% on its first day, with its market capitalization surpassing 3 trillion yuan, making it the new leader in A-share market cap and causing global investors to reassess the competitive landscape of the DRAM industry in the coming years.

China's DRAM Leader's Listing Triggers Global Memory Sector Revaluation

Regarding Monday's sharp drop in U.S. memory chip stocks, multiple foreign media outlets believe the market's concern is not about CXMT's short-term results, but the potential change in global DRAM supply structure in the future.

Analysts believe that CXMT's completion of the largest IPO in Asia this year means the company has gained more abundant capital support, boosting its future capacity expansion, R&D, and capacity to move into high-end AI storage fields such as HBM. For the global memory chip leaders whose shares have already risen sharply, this means long-term competitive pressure is increasing.

Some commentators point out that the market worries that following CXMT's fundraising, the release of new DRAM supply may accelerate, thereby undermining the market's current optimism for a sustained rise in memory prices. At the same time, memory chip stocks like Micron, SK Hynix, and SanDisk have already risen substantially, and under high valuations, any change in the competitive landscape could easily trigger profit-taking.

Other commentators consider this round of correction more of a market repricing. Although HBM demand driven by AI remains strong, investors have begun to rethink: if Chinese companies continuously improve their capacity and technological strength, will the traditional DRAM business enter a phase of increased competition earlier than expected, thereby impacting sector profitability?

However, many analysts believe that the market's reaction might be somewhat exaggerated.

Currently, CXMT's products are still mainly focused on traditional DRAM areas such as DDR4 and DDR5, while Micron, SK Hynix, and Samsung's fastest-growing businesses come from AI storage products such as HBM. Due to U.S. export controls, CXMT still faces high technical barriers to enter the high-end HBM market in the short term, so the global AI storage market structure is unlikely to undergo fundamental change in the near term.

CXMT's Surge on Its First Day Shows Capital Markets' Bet on "China Memory"

CXMT's IPO has already garnered global attention.

The company raised about 57.9 billion yuan (about $8.6 billion), making it the largest IPO fundraising in Asia this year. On its first day of listing (Monday), the company's share price closed 465.82% above its IPO price, with a total market capitalization of 3.28 trillion yuan, surpassing ICBC to become number one in A-share market capitalization, equivalent to twice that of Kweichow Moutai.

All day Monday, CXMT's turnover exceeded 140 billion yuan, making it the first A-share stock in history to break 100 billion yuan in single-day turnover.

Public information shows that CXMT was founded in 2016. It is China's largest DRAM chip manufacturer and a representative enterprise for China’s indigenous DRAM R&D and mass production. The company's products cover consumer electronics, PCs, servers, automotive electronics, and other fields, and it is continuously advancing R&D of new products like DDR5.

Domestic media generally believe that the listing of CXMT is not only a new milestone for China's semiconductor industry, but also means the capital market is granting higher valuation premiums to domestic high-end manufacturing and “hard tech” companies. The market expects the raised funds to further support advanced process R&D, capacity expansion, and the improvement of the domestic memory industry chain.

In the AI Era, HBM Still Decides the True Winner

However, from a global competition perspective, most institutions still believe that Micron, SK Hynix, and Samsung's leading advantage in the AI storage field is hard to shake in the short term.

With the boom in AI server demand, HBM has become one of the world's most in-demand semiconductor products. Micron and SK Hynix have almost monopolized HBM supply for AI chip makers like NVIDIA; this business is also the main driver behind the rapid growth in profits for both companies.

Therefore, many analysts believe that Monday's decline in memory stocks is more of an emotionally driven valuation adjustment rather than a fundamental turning point. As AI infrastructure construction continues, high-end memory demand is expected to remain strong.

Bernstein analyst Mark Li even believes the correction offered a new opportunity to build positions. He forecasts that by 2027-2028, the global memory chip market revenue could exceed $1.3 trillion, and the construction of data centers in the AI era will continue to support growth in DRAM and HBM demand.
