GlobalWafers outlines 2026 recovery path, highlights tightening 12-inch wafer supply

GlobalWafers’ forecast of a Q1 2026 cyclical trough signals that AI-driven infrastructure demand is forcing a structural reset in upstream wafer capacity. Tightening 12-inch supply will directly inflate manufacturing costs for advanced logic and HBM chips, compelling TSMC and Samsung to lock in long-term wafer supply deals. U.S. CHIPS Act and EU Chips Act compliance now imposes steep localization and export-control burdens, raising operational risk for non-domestic wafer suppliers. In response, Shin-Etsu and SUMCO are likely to reactivate idle lines and deepen customer tech-integration to retain market share. Over the next 18 months, the wafer segment will emerge as the most fragile yet price-dominant node in the semiconductor value chain—any acceleration in AI cluster deployment could ignite a supply gap, triggering spot-price surges and reshaping power dynamics across foundries, OSATs, and materials vendors.
