Industry Analysis
Micron’s surge reflects structural AI memory scarcity, not speculation. Surging HBM demand is forcing a compute-stack overhaul: GPU designers are rushing TSV integration, while TSMC’s CoWoS capacity bottlenecks intensify. Micron leads Samsung by two quarters in HBM3E ramp, but geopolitical strings attached to U.S. CHIPS Act funding bar advanced-node expansion in China, capping its global share upside. With SK Hynix dominating over 50% of HBM supply, Micron may resort to aggressive pricing to secure AI accelerator sockets—eroding margins. The imminent HBM4 transition within 12 months will reset the competitive landscape; failure to anchor NVIDIA’s GB200 supply chain by 2027 could invalidate its current valuation premium.
