China's DRAM milestone arrives with CXMT IPO; HBM now separates contenders from leaders

CXMT’s STAR Market debut marks the completion of China’s DRAM value chain—from tech acquisition to mass production and capital validation. If its HBM3E line achieves yield breakthroughs by 2027, it will directly erode Micron and SK Hynix’s pricing power in AI memory and force TSMC to reshuffle CoWoS allocation priorities. However, the U.S. BIS is likely to tighten exports of ArF photoresists and ALD tools, potentially raising CXMT’s per-bit cost by over 15%. Samsung has already begun pitching 'China-excluded' DRAM solutions to North American cloud providers, signaling a new client-lock-in race. Over the next 18 months, if CXMT secures more than 30% of domestic AI chip-driven demand, its valuation narrative will shift from policy-backed speculation to real supply-demand fundamentals—redrawing global memory power dynamics.
