Gasgoo Munich- On July 27 that A-shares witnessed a major IPO debut as domestic memory leader ChangXin Memory Technologies (CXMT) officially listed on the STAR Market. The offering—the largest fundraising event in the board's history—boosted market sentiment immediately. With an issue price of 8.66 yuan per share, the stock opened at 49.5 yuan, a 471% surge.
The stock price continued to rise, briefly touching 54.65 yuan during the session—an intraday gain of 531.06%. That surge pushed its total market capitalization past 3.6 trillion yuan, surpassing traditional financial giants like Agricultural Bank of China and Industrial and Commercial Bank of China (ICBC). CXMT instantly claimed the top spot in A-share market capitalization, ending the long-standing dominance of banking heavyweights. The company raised nearly 57.9 billion yuan in the listing, setting a new record for STAR Market IPOs.
The significant debut gain affected the secondary market. Data shows the online success rate for CXMT was 0.4714%, making allocation exceptionally scarce. Investors who won a single lot paid just 4,330 yuan but could gain over 20,000 yuan by selling at the opening peak. For many retail investors, that gain arrived just in time, helping offset losses from July’s market retreat.
Throughout July, technology sectors—including semiconductors, AI computing, and liquid-cooled servers—faced a collective correction, shrinking many portfolios. Yet CXMT’s rally has helped revive sentiment across the broader technology sector.
This significant debut is not just speculation—it is underpinned by solid industrial strength and a powerful super-cycle. CXMT is one of China's few vertically integrated DRAM manufacturers, breaking the dominance that Samsung, SK Hynix, and Micron hold over more than 90% of the global market. The firm now stands as the world’s fourth-largest and China’s top player in its field.
As the AI computing sector expands, global memory chips have entered a high-growth upcycle, opening significant room for expansion. Benefiting from these tailwinds and rapid capacity ramps, CXMT’s performance has increased significantly. Revenue and net profit both surged several-fold year-on-year in the first half of 2026, providing the hard fundamentals to support its leap in market capitalization.
In the long run, CXMT’s listing bridges a critical gap in the A-share domestic storage supply chain and reshapes the sector’s valuation framework. It is expected to drive growth in upstream industries like semiconductor equipment and materials, officially ushering in a new era where technology heavyweights lead the A-share market.
