China’s largest memory chipmaker, CXMT, became the most valuable company on the mainland after its shares surged more than 500% on its first day of trading in Shanghai.
The initial public offering pushed CXMT’s market capitalization to 3.65 trillion yuan ($540 billion), surpassing state-owned megabank ICBC. This marked the largest tech share sale in mainland China’s history. The company raised 66.6 billion yuan ($9.8 billion), eclipsing the previous record set by Semiconductor Manufacturing International Corp in 2020.
AI demand fuels chipmaker’s record debut
The surge reflects investor enthusiasm for China’s push to lead the global semiconductor market, particularly as artificial intelligence drives demand for memory chips. CXMT, founded in 2016 and based in Anhui province, is the world’s fourth-largest producer of DRAM chips. It holds just 8-9% of the global market, trailing leaders Samsung (36%), SK Hynix (29%), and Micron Technology (24%).
“The interest reflects investors’ overwhelmingly bullish sentiment toward China’s flagship domestic memory chip firm,” said Larry Yang, chief economist at First Seafront Fund Management. The IPO, he added, would help the company expand production and increase its global influence. Analysts caution that capacity growth will take time—likely a year or more—to materialize.
For now, the AI boom has created a global shortage of DRAM chips, which are essential for smartphones and data centers. The scarcity has driven up prices, and even Apple is reportedly testing CXMT’s chips for its products. This marks a rare acknowledgment from a U.S. tech giant of a Chinese supplier.

Yet the company’s rise faces complications. It appears on the Pentagon’s list of Chinese firms with alleged military ties, though the designation doesn’t legally bar U.S. companies from doing business with it. The listing highlights geopolitical tensions in the semiconductor industry, where China aims to reduce reliance on foreign technology while the U.S. seeks to limit Beijing’s access to advanced chips.
Still, AI-driven demand has lifted the entire sector. Companies like CXMT are gaining traction as customers diversify suppliers. Micron, the U.S. leader, has also benefited, though its valuation remains below that of its larger rivals.
For CXMT, the IPO windfall offers a chance to close the gap with rivals. Long-term success may depend on addressing technical challenges and political pressures in the U.S.-China tech rivalry.
The AI gold rush continues to reshape the industry. Expansion timelines remain long, so the current shortage and high prices are likely to persist.
A turning point for China’s semiconductor ambitions

It marks a potential shift for China’s semiconductor sector, which has long trailed South Korea, Taiwan, and the U.S. in technology and market share. Zhang Guobin, founder of the Chinese tech site eetrend.com, called the listing a “turning point” for the global memory chip industry and China’s broader semiconductor goals.
That view is shared by Ellie Wang, an analyst at TrendForce. She noted CXMT is a viable challenger to the top three. “As customers diversify their supplier base amid the shortage, the company should gain further opportunities,” she said. But she warned the IPO’s proceeds won’t immediately ease the supply crunch—new production lines take time to build.
The timing of the debut aligns with China’s push for self-sufficiency in semiconductors. The government has made this a national priority, investing billions to counter U.S. export controls. Progress has been uneven: Chinese chipmakers have advanced in mature technologies but still rely on foreign equipment for cutting-edge production.
The AI boom provides momentum, but the industry’s future hinges on whether CXMT and its peers can turn enthusiasm into tangible gains. Success will require increasing market share and technological independence.
The company’s next moves will be closely watched. With $9.8 billion in fresh capital, CXMT has resources to expand. The real test will be delivering on its promise to become a global player in a market still dominated by rivals.
