China’s CXMT Surges 466% in Asia’s Largest IPO of 2026

China’s DRAM giant, Changxin Technology Group (CXMT), made headlines with a massive 466% surge on its Shanghai STAR Market debut, raising $8.6 billion and briefly becoming China’s most valuable listed stock at a $487 billion market cap. For those watching the semiconductor space this eye-popping first-day gain was largely a classic low-float squeeze with only about 7% of shares available to trade driven by heavy state support for chip self-sufficiency and reports that **Apple is testing CXMT’s DRAM for local Chinese devices.** The company backed up the hype by swinging to a 35.4 billion yuan Q1 profit, benefiting directly from the ongoing global AI infrastructure boom. while leaders like Micron ($MU) and SK Hynix are shifting cleanroom capacity to high-margin high-bandwidth memory (HBM) for AI, CXMT is aggressively expanding standard DDR5 and mobile memory, targeting **350,000 wafer starts per month** by year-end. However, trade restrictions prevent CXMT from acquiring advanced Extreme Ultraviolet (EUV) tools, leaving its production costs roughly **30% higher** than Western peers. Ultimately, chasing low-float, first-day pops near the top of a memory cycle carries severe downside risk. Rather than buying into the hype, retail investors should monitor how CXMT's massive supply expansion impacts global DRAM pricing over the next two years.
