CXMT's Shanghai Debut Surges 470%, Becoming China's Most Valuable Listed Company

CXMT's Shanghai debut overtook ICBC to become China's most valuable listed company, with a first-day market capitalisation around 3.31 trillion yuan and an opening price near 49.50 yuan.
Regulators and market-watchers signaled stability measures: the CSRC held meetings with listed companies, securities firms, fund managers and academia to guide expectations and bolster market stability, while state-run newspapers published editorials to reassure investors.
CXMT's IPO is the largest mainland Chinese semiconductor offering on record, with proceeds potentially rising to 66.61 billion yuan if the over-allotment is fully exercised, topping the size of SMIC's 2020 listing.
Market reaction and liquidity considerations highlighted by analysts include warnings that the offer could drain liquidity from the broader market before and on its debut, a point observed by market participants and reported by Reuters.
Chinese chipmaker CXMT Corp made a stunning stock market debut in Shanghai on Monday, with shares surging roughly 470% to about 49 yuan — more than five times the IPO price of 8.66 yuan. The jump pushed its market value to around 3.3 trillion yuan ($487 billion), overtaking megabank ICBC to become the most valuable listed company in mainland China, according to MarketScreener.
The IPO raised 57.92 billion yuan, with potential proceeds climbing to 66.61 billion yuan if the over-allotment option is fully exercised — making it the largest mainland Chinese semiconductor listing on record, per NDTV Profit. Only 6.73% of shares are freely tradable at listing, a factor that amplified the early price surge.
CXMT opened at roughly 49.50 yuan per share, far above its 8.66 yuan IPO price. That single-day move valued the company at about 3.31 trillion yuan. That is larger than any bank, insurer, or energy giant listed on the mainland, according to Head Topics.
The listing also topped the size of SMIC's 2020 Shanghai debut, which was the previous record for a Chinese chip IPO. CXMT is the world's fourth-largest DRAM producer. DRAM is the type of memory chip used in computers, phones, and AI servers.
The massive appetite for CXMT shares reflects a broader supply crunch in memory chips. AI systems need huge amounts of fast memory, and global supply has not kept up with demand. CXMT plans to use IPO funds to expand wafer production and ramp up research and development, according to Head Topics.
Reports also note that Apple has begun testing CXMT's DRAM for devices sold in China. That disclosure added to investor excitement. Analysts see rising domestic AI demand as a steady tailwind for the company in the years ahead.
The sheer size of the IPO raised concerns among analysts that it could drain cash from the rest of the market. Investors often sell other stocks to free up money for a hot new listing. MarketScreener reported that market participants flagged this risk in the days before CXMT's debut.
China's securities regulator, the CSRC, held meetings with listed companies, brokerages, fund managers, and academics to guide expectations. State-run newspapers also published editorials to reassure investors about market stability. The moves reflect Beijing's sensitivity to sharp swings in financial markets.
CXMT's debut is a milestone for China's push to build a homegrown chip industry. The company competes with South Korea's Samsung and SK Hynix in DRAM memory. Western export restrictions on advanced chip tools have pushed Beijing to invest heavily in domestic producers like CXMT.
The stock's first-day performance is now seen as a test of how much investors will pay for a top Chinese chip firm during a volatile period for tech shares. With AI demand still growing fast, analysts expect memory chip stocks to stay in the spotlight, according to MarketScreener.
