A company founded ten years ago is now the most valuable listed in mainland China. CXMT, the memory-chip maker at the center of Beijing’s semiconductor ambitions, sported a market capitalization equivalent to $484 billion after its opening day of trading in Shanghai — topping Industrial & Commercial Bank of China and landing just short of Tencent, the most valuable company listed in Hong Kong.
The numbers behind the pop
Shares in the offering were sold at 8.66 yuan, equivalent to $1.28 — a conservative price that analysts said reflected industry uncertainty and a desire to ensure a pop after the listing. It worked. Investors lucky enough to win the share lottery saw their money more than quintuple, a 466% gain on the first day, with the stock closing at 49 yuan. CXMT is raising at least $8.55 billion in the offering and said it would use the money to upgrade production lines and technology.
The underlying growth is genuinely startling. In the first quarter, CXMT’s revenue rose to $7.5 billion from less than $1 billion a year earlier, and profit rose to $3.66 billion as the memory-chip shortage allowed the company to secure generous price increases from customers. It is building three new factories that would more than double its current capacity by the end of 2027.
The oligopoly gets a fourth member
Until now, the memory business has been dominated by three companies: SK Hynix (000660.KS) and Samsung (005930.KS) of South Korea and Micron Technology (MU) of the United States. Research firm SemiAnalysis predicts CXMT’s global share will grow to 12% by next year, up from an estimated 9% in 2025, cementing a No. 4 position behind the big three. Right behind CXMT is Yangtze Memory Technologies, or YMTC, which makes NAND flash memory and is planning its own Shanghai listing as soon as this year.
CXMT acknowledged in its prospectus that its products still trail the industry leaders, in part because U.S. export controls prevent it from buying top-of-the-line Western chip-making equipment. Lacking state-of-the-art foreign machinery, the company has adopted multi-patterning to squeeze more circuitry onto a single wafer and invested in advanced packaging, stacking circuitry in unconventional ways to boost performance. Analysts said those techniques increase the risk of errors and reduce yield — the percentage of usable chips on a wafer. SemiAnalysis says CXMT’s yields have improved but remain below industry standards. The chips are nonetheless good enough for wide use in consumer electronics and AI data centers.
Apple wants what Washington does not
Concerned about losing sales to price-conscious consumers, Apple (AAPL) Chief Executive Tim Cook and top executives have pitched President Trump and other U.S. officials on a plan to use CXMT and other Chinese chips in Apple products sold outside the United States. Apple is clashing with Micron, which argues that letting CXMT sell to U.S. technology companies would hurt American industry.
Whether Apple gets what it wants may not matter much in the near term. CXMT said in its prospectus that its production capacity still fell short of demand within China, and earlier this year Beijing told Chinese memory makers including CXMT to give priority to local buyers. Ming-Chi Kuo of TF International Securities wrote that even if Apple’s lobbying succeeds and it buys DRAM from CXMT, that would not materially lower costs or fill the supply gap — though he added that, given the persistent global memory imbalance, “Apple has every reason to secure an additional source,” and both Chinese companies would welcome adding Apple to their customer lists as an endorsement. China’s government, hoping to free the country from dependence on American and allied technology, has backed CXMT with money from a national chip-investment fund and pushed domestic makers to buy domestic equipment.
The same weekend, the campaign against Nvidia
The listing did not happen in a vacuum. In the weekend paper, the Journal laid out Beijing’s effort to break its dependence on Nvidia within three years: Huawei held a closed-door briefing for the country’s technology czar to introduce its latest artificial-intelligence chips, exactly what Vice Premier Ding Xuexiang — a confidant of Xi Jinping — wanted to hear. With Xi’s blessing, Ding started a fevered effort to forge domestic alternatives, reaching back to the playbook China used after its rift with the Soviet Union: a committee drawn from the country’s best companies and labs, organized into specialized teams and directed at one objective.
The market noticed. Chip stocks in the United States declined again Monday, weighing on the Nasdaq Composite. Shares of Nvidia fell 5%, dragging its value below that of Apple and snapping a 272-trading-day streak as the largest U.S. company by market capitalization. Apple, which has never cracked the $5 trillion threshold Nvidia hit late last year, is closing in on it.
Two facts can be true at once: American AI leadership is real, and the moat is being dug from the other side too. A $484 billion IPO day for a memory company is China’s capital market voting that the campaign works. The direct casualty if it does is not Nvidia first — it is the memory oligopoly: SK Hynix, Samsung and Micron (MU). Action: WATCH MU — we do not own it directly, and the CXMT debut is the reason a cheap-looking memory cycle may stay cheap. HOLD AAPL; the supply chain wants CXMT to succeed even while Washington does not. The China sleeves in the global book remain index-level — this is a theme we rent through breadth, not a single name we marry.
