The IPO Surge and First-Day Trading
On July 27, ChangXin Memory Technologies (CXMT Corp.) opened trading on Shanghai’s STAR Market at 49.50 yuan, far above its 8.66 yuan IPO price. The stock surged as much as 470 % in the opening minutes, lifting market capitalisation to roughly 3.3 trillion yuan. At the close of the first session shares were near 49.5 yuan, making CXMT the most valuable mainland-listed company, overtaking Industrial and Commercial Bank of China. The offering raised 57.92 billion yuan (about $8.6 billion) and could increase to 66.61 billion yuan if the over-allotment option is exercised. Only about 6.7 % of the enlarged share capital was freely tradable at listing, a factor that may amplify price swings.
Background and Market Position
Founded in 2016 by Chairman Zhu Yiming, CXMT is based in Hefei, Anhui. The prospectus reports a 7.67 % share of the global DRAM market at the end of 2025, making it the world’s fourth-largest DRAM producer behind Samsung, SK Hynix and Micron. Revenue in Q1 2026 reached 50.8 billion yuan, a 719 % year-over-year increase, while net profit rose to 33 billion yuan from a loss a year earlier.

Capacity is projected to reach roughly 325,000 wafer starts per month by year-end 2026, still below the combined capacity of the three global leaders but indicative of rapid scaling.
