CXMT (China's domestic DRAM champion) debuts in Shanghai IPO at 3.66 trillion yuan market cap with 500%+ surge, circumventing US HBM export controls.
Shares of CXMT, China's largest memory chipmaker, surged approximately 470% on their debut on the Shanghai Stock Exchange's STAR market, marking one of mainland China's largest initial public offerings in recent years. The company priced shares at 8.66 yuan (approximately $1.3) each, raising at least $8.6 billion.
Founded in 2016 in Hefei, CXMT manufactures DRAM (dynamic random access memory) chips essential for AI servers, smartphones, personal computers, and other consumer electronics. The artificial intelligence boom has significantly accelerated growth: the company reported Q1 2026 revenue of 50.8 billion yuan ($7.5 billion), representing a 700% year-on-year increase.
CXMT's timing reflects China's broader push for technological self-sufficiency amid U.S. export controls on advanced chipmaking equipment. The company addresses a critical gap, as American restrictions limit China's access to high-bandwidth memory (HBM) chips. According to Counterpoint Research, CXMT held 6% of the global DRAM market in 2025, ranking fourth by shipments globally, and captured approximately 9% of global shipments in Q1 2026. Counterpoint estimates its share could rise to 11% by 2028, though the company would need 15% to achieve long-term competitiveness, as research director MS Hwang noted.
The company faces substantial obstacles, including supply chain bottlenecks and reliance on domestic equipment manufacturers due to international restrictions on leading-edge chipmaking tools. Geopolitical headwinds intensified when the Pentagon designated CXMT as linked to the Chinese military—a designation Beijing has denied—prompting U.S. lawmakers to seek restrictions on American companies purchasing CXMT memory chips for national security reasons.
CXMT's IPO follows South Korea's SK Hynix raising $26.5 billion through a concurrent Nasdaq listing, underscoring rising global competition for memory chips as artificial intelligence demand accelerates.
