Seldom has a market debut so dramatically reshaped a nation's corporate hierarchy. CXMT, China's foremost DRAM manufacturer, closed its inaugural trading session up 466%. The Hefei-based chipmaker's market capitalization soared to approximately $488 billion. This extraordinary surge propelled CXMT past banking giant ICBC as China's most valuable onshore-listed company.
The IPO itself constituted a landmark event in Asian capital markets. CXMT raised 57.92 billion yuan, equivalent to $8.6 billion, on Shanghai's STAR Market. This surpassed the previous record set by SMIC's $7.5 billion offering in 2020. Notably, only 6.73% of total shares were available for trading, amplifying the price volatility considerably.
Founded with state backing in 2016, CXMT has emerged as a formidable challenger in the global memory chip sector. The company held approximately 8% of the worldwide DRAM market in 2025 by shipments. Samsung Electronics, SK Hynix, and Micron Technology collectively dominate the remainder. Analysts forecast CXMT's market share could reach 11% by 2028 as new production lines come online.
Several catalysts have underpinned this remarkable valuation. Surging artificial intelligence demand has tightened global DRAM supply chains considerably. Apple has reportedly begun testing CXMT's memory chips for devices sold in China. Furthermore, CXMT guided first-half revenue of up to 120 billion yuan, representing a sevenfold increase year-on-year.
Nevertheless, significant headwinds persist for the company. U.S. trade restrictions on advanced chipmaking tools remain a pivotal constraint on CXMT's technological advancement. The company appears on the Pentagon's blacklist of firms with alleged military ties. Whether this unprecedented debut reflects sustainable fundamentals or speculative exuberance will become apparent in subsequent quarters.
