Changxin Storage Technology, China's largest DRAM manufacturer, made a blockbuster market entrance on July 27 when it listed on the Shanghai Stock Exchange's Science and Technology Innovation Board under the name Changxin Technology [2]. The stock opened at 49.5 yuan per share, representing a staggering 471.59% jump from its initial offering price of 8.66 yuan [2]. By midday trading, the company's market capitalization had surged to 3.66 trillion yuan, surpassing tech giants including Intel (3.14 trillion yuan) and Hong Kong's Tencent Holdings (3.48 trillion yuan) to become the highest-valued listed company on mainland China's stock exchanges [3].

The IPO raised 579.19 billion yuan in total fundraising, setting a new record for the Science and Technology Innovation Board [1]. Founded in 2016 and headquartered in Hefei, Anhui Province, Changxin Storage is led by chairman Zhu Yiming [4][5]. Only 7% of the company's shares are available for public trading, contributing to the extreme price volatility [4]. Investors who won allocation in the lottery subscription system stood to gain approximately 20,420 yuan per successful lot [2]. The company plans to deploy the raised capital toward expanding chip production capacity and strengthening research and development efforts [4].
