China's CXMT Shares Jump 472% Following $9.8 Billion IPO

China's semiconductor ambitions received a major boost on Monday as memory chipmaker CXMT Corp. made a spectacular stock market debut in Shanghai, with its shares surging 472% at the opening bell. The strong performance followed the company's record-breaking initial public offering (IPO), which raised up to 66.6 billion yuan ($9.8 billion), making it the second-largest IPO in China's history. Formerly known as ChangXin Memory Technologies, the listing has positioned CXMT as China's largest publicly traded company by market value on the mainland.

The company sold 6.688 billion shares, before any overallotment option, at an issue price of 8.66 yuan per share. Trading began at 49.50 yuan, giving the Hefei-based company an estimated market valuation of around 3.3 trillion yuan. The offering was surpassed only by Agricultural Bank of China's landmark $10 billion IPO in 2010. The share sale also attracted attention for its use of the numbers six and eight, which are traditionally regarded as symbols of prosperity and good fortune in Chinese culture.

CXMT has emerged as one of China's most important semiconductor companies as Beijing seeks to reduce its reliance on foreign chipmakers. Ranked as the world's fourth-largest producer of dynamic random-access memory (DRAM) chips, the company supplies technology used in smartphones, personal computers, data centres and artificial intelligence servers. It is also investing heavily in high-bandwidth memory (HBM), a key component powering advanced AI applications and next-generation computing infrastructure.

Investor demand for the IPO was exceptionally strong. The retail portion of the offering was oversubscribed 212 times, with individual investors placing approximately 9.4 million orders worth around 7.07 trillion yuan. Analysts said the overwhelming demand reflected confidence in China's AI and semiconductor sectors, as well as attractive IPO pricing. Chinese regulators have generally maintained conservative pricing policies for new listings, often resulting in lower issue valuations that encourage strong first-day trading gains.

Market analysts also pointed to CXMT's relatively modest valuation compared with global competitors. Based on the IPO price, the company was valued at approximately 2.4 times its book value, representing a significant discount to international memory chip manufacturers such as SK Hynix, Micron Technology and Nanya Technology, as well as leading Chinese semiconductor firms. While some investors remain cautious after recent volatility in AI-related stocks, many believe CXMT has substantial room for expansion as demand for advanced memory chips continues to grow worldwide.

The successful listing is expected to strengthen China's domestic semiconductor industry and could pave the way for other major technology companies seeking public listings. Industry observers believe firms such as Yangtze Memory Technologies, Baidu's chip unit Kunlunxin and AI startup DeepSeek could benefit from renewed investor confidence in the sector. Analysts forecast strong long-term growth for CXMT, driven by expanding AI adoption, increasing demand for advanced memory solutions and continued government support for achieving greater technological self-reliance.
