AI demand exposes HBM, power, packaging, storage and manufacturing bottlenecks

Samsung's strong Q3 2026 guidance confirms exceptional AI-memory demand, while potential AMD-Samsung cooperation and Micron's U.S. commitments add longer-term supply signals. TSMC's October 15 earnings preview is especially important for HPC demand, 2nm margin dilution, CoWoS capacity and pricing power; elevated memory costs may also pressure consumer-device demand, although Apple's reported iPhone 18 Pro order reduction remains unverified.
