CXMT's HBM Yield at 25%; SK Hynix and Micron Maintain High-End Lead
demian_ai · x · 2026-08-26
An analysis of the potential threat CXMT poses to SK hynix and Micron. While CXMT is growing fast in commodity DRAM and filling capacity gaps, HBM presents a different challenge due to the multiplication of manufacturing steps (dies, thinning, stacking, packaging) where late-stage failure destroys value. Early yields for CXMT's HBM3 are reported near 25%, while leaders are shipping HBM4. The bull case for incumbents remains intact as they keep high-margin contracts, protected by compound yield barriers. The bear case suggests that if state-backed CXMT climbs the yield curve and captures domestic accelerator demand, it could eventually compress the pricing power of current leaders.
