Changxin Technology Group's shares surged nearly 466% on their Shanghai STAR Market debut Monday, giving the Hefei-based DRAM chipmaker a market cap of roughly 3.3 trillion yuan and making it China's most valuable listed company.
Shares of Changxin Technology Group soared nearly 466% Monday in their first day of trading on Shanghai's STAR Market, catapulting the Hefei-based chipmaker to the top of China's market capitalization rankings in one of the most closely watched IPOs of the year.
CXMT closed at 49 yuan per share, giving the company a market cap of approximately 3.3 trillion yuan — surpassing Industrial and Commercial Bank of China's 2.6 trillion yuan and making CXMT the most valuable company listed on a Chinese exchange.
The company had priced its IPO at 8.66 yuan per share, raising 57.92 billion yuan ($8.6 billion), making it Asia's largest IPO so far this year. CXMT plans to deploy those proceeds primarily toward mass-producing memory wafers and funding research and development projects.
Based on fourth-quarter 2025 sales figures, CXMT held a 7.67% share of the global DRAM market, according to its IPO prospectus. DRAM chips are used across a wide range of electronic devices, from smartphones to servers. The global DRAM market is currently dominated by Samsung Electronics, SK Hynix, and Micron Technology.
The listing draws additional attention following reports earlier this month that Apple has begun testing CXMT's DRAM chips for devices sold in China — a development that underscores the chipmaker's growing profile among major technology manufacturers.
CXMT also reported a swing to an operating profit of 35.43 billion yuan in the first quarter of 2026, compared with a loss of 2.83 billion yuan in the same period a year earlier, reflecting continued growth in global computing power demand and capacity allocation by major manufacturers.
"A 470% performance on day one isn't that rare. What's very prominent in this particular case is a company of this size performing so well," said Theodore Shou, CEO at Yiyi Capital. He attributed the surge largely to a relatively limited free float on the first day of trading, combined with built-up market sentiment.
Shou expressed confidence in CXMT's long-term trajectory. "I have no doubt the company is going to grow to be a global leader. It's maybe just a question of time that it can be not only a challenger, it can be a global champion in this particular sector," he said.
Morningstar noted in a research note Friday that as AI becomes an issue of national security for China, CXMT will likely be a key beneficiary. The firm added that while CXMT's technology still lags global memory leaders, domestic internet giants driving AI development will likely push robust adoption of its chips as Beijing pursues semiconductor self-sufficiency.
CXMT was founded in 2016 by Chairman Zhu Yiming. The company's debut comes amid a broader push by China to develop homegrown semiconductor capabilities, with state-backed investment and government policy reinforcing demand for domestically produced memory chips.
Despite the euphoric first-day performance, Shou offered a note of caution. "I think we are nearing a short-term peak in terms of sentiment around the memory cycle," he said, pointing out that investors have already been selling into the IPO. "These memory chip businesses are sustainable, but the great margins and net profitability we're seeing today are not sustainable and have to normalize over a cycle."
He added that while current share prices may not yet represent a definitive peak, the market is at the height of a demand-and-supply imbalance — a dynamic that has historically presaged a correction in memory chip valuations. Whether CXMT can sustain its lofty market cap will depend in large part on its ability to close the technology gap with its established global rivals.
