Le plus grand fabricant chinois de mémoire fait son entrée en bourse avec un bang

The largest Chinese memory chip manufacturer made its stock market debut with explosive gains, setting records and drawing comparisons to global tech giants. On July 27, 2026, ChangXin Memory Technologies (CXMT) saw its shares surge by over 466 percent during its first trading day on the Shanghai Stock Exchange. The company’s stock price briefly reached as high as 55 yuan (approximately 7.13 euros), marking a staggering increase of up to 535 percent from its initial public offering (IPO) price of 8.66 yuan (about 1.12 euros). At the close of trading, the share was valued at 49 yuan (around 6.35 euros), giving CXMT a market capitalization of approximately 425 billion euros, making it the most valuable company listed on mainland China's stock exchanges. This valuation places CXMT roughly on par with Tencent, which is listed on the Hong Kong Stock Exchange. Tencent owns the popular messaging app WeChat, the video game publisher Riot Games, and holds a 40 percent stake in Epic Games, the developer behind Fortnite. While CXMT’s value surpasses that of many Western firms, including Germany’s Siemens, which has a market cap of around 216 billion euros, it still trails behind some of the world’s leading semiconductor companies. The sharp rise in CXMT’s stock reflects ongoing demand for memory chips amid a global shortage. As one of the largest Chinese producers of DRAM chips, used in DDR5 modules and LPDDR components, the company holds an estimated eight percent share of the global DRAM market, placing it fourth among major manufacturers. Analysts estimate that CXMT’s position in the industry is growing, driven by increased production capacity and expanding customer bases, including potential interest from international clients such as Apple, which may seek to diversify its supply chain. CXMT’s performance contrasts with that of its main competitors. Micron, the third-largest DRAM producer based in the United States, has a market share of 22 percent and a market capitalization of approximately 913 billion euros. Meanwhile, South Korean leaders Samsung and SK Hynix dominate the sector, with Samsung holding 38 percent of the DRAM market and a market cap of 878 billion euros. SK Hynix follows with a 29 percent share and a valuation of 772 billion euros. Despite its rapid ascent, CXMT’s valuation appears lower than these established players, though its growth trajectory suggests it could challenge them in the coming years. Currently, CXMT is ramping up production capabilities and has begun securing contracts with Western customers. This expansion comes as the global semiconductor industry continues to grapple with supply constraints and shifting trade dynamics. The company is now required to publish quarterly financial reports following its IPO, providing investors with more transparency into its operations and performance. As the memory chip market evolves, CXMT’s success highlights the increasing influence of Chinese technology firms in global markets. With continued investment and strategic partnerships, the company is well-positioned to solidify its place among the world’s top memory chip manufacturers. Its journey underscores the dynamic nature of the semiconductor industry and the growing role of emerging economies in shaping its future.
