ChangXin Memory Technologies (CXMT), China's leading DRAM manufacturer, saw its shares jump 12% to a record close, pushing its market capitalization beyond 4 trillion yuan. The surge underscores the company's expanding role in the global memory chip market, driven largely by increasing artificial intelligence applications demanding higher memory capacity.
- CXMT stock closes at a record 61.80 yuan, market cap hits 4.13 trillion yuan
- Global AI demand drives tighter memory supplies and long-term growth forecasts
- UBS predicts CXMT will increase global DRAM market share to 10% by 2028
What happened
Shares of ChangXin Memory Technologies (CXMT) climbed 12% on Monday, closing at 61.80 yuan, its highest level yet. This lifted the company’s market valuation to 4.13 trillion yuan, solidifying its position as China’s most valuable publicly traded company, surpassing Tencent Holdings. The stock's rise is part of a broader sector rally, with other memory chip makers like SanDisk and Micron also seeing significant gains amid robust demand expectations.
CXMT first stole the spotlight with a strong debut on mainland exchanges in late July, where its shares surged by 466% from the initial public offering price of 8.66 yuan. The company recorded substantial financial gains in the first quarter, posting a 719% increase in revenue year-on-year and reversing previous losses to report a net profit of nearly 25 billion yuan.
Why it matters
The rally in CXMT shares reflects the rising importance of memory chips powered by artificial intelligence technology. The shift to memory-centric AI architectures, due to larger models requiring more data capacity, is tightening DRAM supply globally. Industry analysts like UBS and Bernstein have highlighted long-term growth potential in the DRAM market, with expectations that demand from data centers will continue to drive capacity expansion and new technology adoption.
China’s strategic focus on domestic chip manufacturing and AI development strengthens CXMT’s role in the supply chain, while companies like SenseTime turning profitable indicate a growing and maturing AI industry within the country. This positions CXMT not only as a market leader but also as a critical player in China’s semiconductor ambitions and global AI hardware ecosystem.
What to watch next
Market participants will closely monitor CXMT’s production capacity growth plans through 2028, as UBS forecasts an increase from 240,000 wafers per month in 2025 to 466,000 wafers per month by 2028. How effectively CXMT can capture a greater share of the global DRAM bit supply amid ongoing undersupply conditions will be key to sustaining its valuation and revenue momentum.
In parallel, developments in AI workloads demanding advanced memory technologies, including high-bandwidth flash innovations from related companies, will influence supply-demand dynamics. Additionally, tracking profitability and market performance of other Chinese AI-focused firms like SenseTime will provide insights into the broader health and expansion of China's AI and semiconductor sectors.
