TAIPEI, May 29, 2026 — The global semiconductor wafer industry has entered a full-fledged upward cycle in 2026, fueled by explosive AI computing demand and a broad recovery in automotive electronics, industrial control, and power semiconductor markets. Widespread price adjustments across wafer suppliers and foundries, coupled with targeted capacity expansion and technological upgrades, have reshaped the global supply-demand landscape, ending the sluggish market conditions seen in late 2025.
GlobalWafers, the world’s leading silicon wafer manufacturer, confirmed the industry’s robust turnaround during its recent shareholder meeting on May 25, 2026. Hsu Hsiu-Lan, Chairperson of GlobalWafers, noted that the 2026 market has delivered a striking improvement compared with the uneven performance of 2025. While high-end wafers for AI servers and high-performance computing maintain strong momentum, traditional downstream sectors including industrial equipment, energy storage systems, power grids and automotive components have achieved steady demand growth, forming diversified driving forces for the wafer industry. Facing rising costs for raw materials, energy and logistics, the company is actively negotiating phased price increases with global clients to be implemented in the second half of 2026, with its production lines currently running at full capacity amid tight market supply.
A full-scale wafer price hike wave has swept the global market since early 2026, centered on mainstream 8-inch wafer products widely used in power semiconductors, BCD processes and automotive analog chips. Leading foundries including United Microelectronics Corporation (UMC) have announced price adjustments, with overall 8-inch wafer prices rising by 10% to 15%. International semiconductor giants such as Infineon, Texas Instruments and ON Semiconductor have also rolled out successive price increases for power semiconductor-related wafer products since May 2026, with some product lines seeing hikes of up to 20%, responding to sustained wafer supply shortages.
Industry insiders attribute the persistent price uptrend to structural supply-demand imbalances. The booming demand for electric vehicles, industrial automation and AI data center power devices has kept 8-inch wafer orders at a high level, while global mature-process wafer capacity expansion progresses slowly, failing to catch up with rapidly growing market demand. SEMI’s latest industry report indicates that global semiconductor market scale is expected to exceed one trillion US dollars by the end of 2026, four years earlier than previously projected, further driving sustained growth in wafer consumption.
In the advanced wafer manufacturing segment, competition and capacity layout continue to intensify. TSMC maintains its dominant position in the global foundry market, capturing 72% of the global wafer foundry market share in the first quarter of 2026. Its market share in advanced processes below 7nm exceeds 90%, and it is expected to hold over 95% of the global AI accelerator chip wafer market for the full year. The company’s 18 new 300mm wafer fabs are under parallel construction, focusing on mass production capacity expansion for 3nm and 2nm processes, with the yield rate of core 2nm processes exceeding 80% to meet surging AI chip order demands.
Global semiconductor manufacturers are accelerating differentiated capacity and technological layout to seize market opportunities. Samsung Electronics has officially restarted its silicon carbide (SiC) wafer foundry business and stepped up the construction of 8-inch SiC wafer production lines, positioning wide-bandgap semiconductor wafers as a new core growth engine, with mass production scheduled for 2028 to target high-end power and automotive semiconductor markets.
Regional capacity restructuring has become a key trend in 2026. Driven by accelerated domestic substitution and robust local market demand, Chinese wafer manufacturers are continuously optimizing product structures and expanding high-quality capacity. Leading domestic foundries have maintained high capacity utilization rates above 93% in Q1 2026, with sustained order growth in BCD processes, storage chips and industrial logic wafers, further supplementing global mature-process wafer supply.
Technological innovation continues to underpin industry upgrading. Beyond traditional silicon wafer optimization, breakthroughs in new material wafer processing and ultra-precision planarization technologies have effectively improved chip manufacturing yield and performance stability. Advanced wafer manufacturing technologies are gradually adapting to the iteration requirements of next-generation AI chips, automotive-grade semiconductors and high-efficiency power devices.
Looking ahead, industry analysts predict the global wafer market will maintain prosperity throughout 2026 and 2027. Mature-process wafer supply tightness will persist in the short term, supporting steady price increases, while advanced process capacity expansion and new material wafer industrialization will become the core development directions. Continuous supply chain diversification, technological iteration and regional capacity optimization will further drive the high-quality development of the global semiconductor wafer industry.
