Global silicon wafer prices have seen their first across-the-board increase in over three years, with 6-inch, 8-inch, and 12-inch wafers rising by at least 10% due to surging AI compute demand.
What Happened
Industry-Wide Price Hikes: Driven by the explosive growth in AI computing demand, the global silicon wafer market is experiencing its first across-the-board price increase in over three years. Prices for 6-inch, 8-inch, and 12-inch wafers have risen by at least 10%, signaling a new upward cycle for the semiconductor material industry.
Market Supply and Demand: High-end specialty wafers for AI and HPC applications are leading the charge with price hikes of 18% to 22%. As inventory destocking concludes and demand for automotive and industrial power chips recovers, 8-inch and 6-inch wafers are also entering a catch-up phase, tightening overall market supply.
Corporate Outlook: Major manufacturers, including GlobalWafers, Formosa Sumco, and Wafer Works, are actively renegotiating pricing with clients and expect a stronger second half of the year. While long-term contracts may delay the impact on financial reports, companies anticipate that the benefits of these price adjustments will materialize by late 2026.
Capacity Expansion: Chinese manufacturers are aggressively investing in 12-inch wafer capacity to bolster domestic supply chains. Despite concerns regarding potential oversupply, industry players emphasize that the high capital intensity and long ramp-up times for wafer production act as a natural barrier, limiting the risk of a supply glut in the near term.
