Industry Analysis
Micron’s 700%+ stock surge reflects not just AI memory demand but dangerous valuation overextension. Technically, HBM4E’s reliance on EUV and 3nm processes will inflate yield costs and force TSMC and Samsung to accelerate CoWoS/TSV capacity—raising barriers across the AI chip stack. On compliance, despite China revenue falling below 10%, any U.S. expansion of HBM export controls could disrupt global delivery timelines. Competitively, Samsung is racing to lock in HBM4 design wins, while SK hynix bets on hybrid bonding; Micron risks falling out of the top three if HBM4E scale-up lags into 2026. Over the next 12–24 months, the market will swing from shortage to oversupply. Current pricing assumes flawless execution through 2027—a fantasy in a cyclical industry. Smart money is stepping back, not stepping in.
