Shares of Chinese memory chipmaker CXMT soared nearly 470% during their debut on the Shanghai stock exchange Monday, pushing the company's market capitalization to about 3.3 trillion yuan. This surge followed Asia's largest initial public offering (IPO) of 2026, where CXMT raised 57.92 billion yuan, roughly $8.6 billion.

The company's shares were initially priced at 8.66 yuan but opened at 49.50 yuan, reflecting strong investor enthusiasm fueled by rising memory chip prices driven by artificial intelligence (AI) demand. According to Reuters, only 6.73% of CXMT's total shares were freely traded at listing, underscoring limited liquidity amid high market interest.

Individual investors overwhelmingly participated, submitting 9.4 million orders worth 7.07 trillion yuan. This demand led to a retail tranche oversubscription 212 times over, with the retail order book about ten times larger than the record-setting IPO of SpaceX.

By market value, CXMT overtook Industrial and Commercial Bank of China (ICBC), becoming the most valuable company listed in mainland China. The company's rapid rise highlights its critical role in the expanding AI infrastructure sector.

Strong Financials Backed by Exploding AI Memory Demand

Behind this market excitement lies a solid financial performance: CXMT reported a first-quarter operating profit of 35.43 billion yuan, a stark turnaround from a 2.83 billion yuan loss the previous year. This leap aligns with a roughly 93% quarter-over-quarter increase in contract prices for conventional DRAM in Q1, according to TrendForce. Industry revenues climbed 81% to $97 billion in the same period.

As the world's fourth-largest DRAM producer, CXMT accounted for 7.67% of the global DRAM market in 2025, per its IPO prospectus. Despite Samsung, SK Hynix, and Micron collectively holding about 90% market share in early 2026, CXMT's growth signals shifting dynamics in memory supply amid AI-driven demand surges.

According to industry observers, CXMT's IPO success and valuation leap reflect investors’ ongoing appetite for exposure to AI memory chip makers, a segment experiencing rapid expansion thanks to growing AI infrastructure needs.
