June 17, 2026 | SAN JOSE, CALIFORNIA — Driven by explosive demand for artificial intelligence chips, high-performance computing (HPC) devices and power semiconductors, the global semiconductor silicon wafer market maintained robust growth in the first quarter of 2026, accompanied by continuous price hikes across mainstream wafer specifications. Latest official data released by SEMI Silicon Manufacturers Group (SMG) reveals that worldwide silicon wafer shipments reached 3,275 million square inches in Q1 2026, marking a 13.1% year-on-year increase despite a mild 4.7% sequential drop amid seasonal production adjustments.
Global leading silicon wafer manufacturers including Shin-Etsu Chemical, SUMCO and GlobalWafers have rolled out the second round of price increases in 2026 starting from early May. The overall quotation for 12-inch high-purity silicon wafers rises by more than 15% cumulatively since the start of the year, while customized wafers dedicated to AI and HPC chips see a steeper price surge ranging from 18% to 22%. Industry analysts confirm that this round of price growth stems from long-term conservative capacity expansion by wafer giants and skyrocketing orders for AI-related semiconductor components worldwide.
Market segmentation shows obvious structural differentiation across different wafer sizes. The supply of 8-inch mature-node wafers continues to shrink globally, as leading foundries such as TSMC and Samsung adjust production capacity to prioritize high-margin advanced AI chip processes. TrendForce statistics indicate global 8-inch wafer supply drops by 2.4% year-on-year in 2026, and the average fab utilization rate of mature wafer production lines climbs from 75%-80% in 2025 to 85%-90% this year, pushing up prices for power IC and sensor chips built on mature nodes.
Besides traditional silicon wafers, third-generation semiconductor wafers represented by silicon carbide (SiC) witness rapid market expansion. The booming new energy vehicle and industrial power electronics sectors greatly lift demand for SiC wafers. While global mainstream SiC wafer supply remains tight, regional suppliers have launched cost-effective 6-inch SiC wafer products to ease market pressure, bringing moderate price declines in mid-end SiC wafer segments and accelerating the popularization of wide-bandgap semiconductor devices.
Major wafer manufacturers are accelerating global capacity layout to ease persistent supply shortages. Okmetic officially launched volume production at its upgraded Vantaa wafer fab in early 2026, expanding production capacity for 150mm and 200mm specialty wafers for automotive and industrial chips. Meanwhile, leading wafer suppliers are prolonging long-term supply contracts with top chip foundries, locking wafer orders for 12 to 24 months in advance to stabilize upstream and downstream supply chains.
Despite strong market prospects, the global wafer industry still faces notable challenges. Fluctuating raw material costs for high-purity polysilicon, strict global semiconductor trade regulations, and massive capital expenditure requirements for advanced wafer production lines hinder faster capacity expansion. In addition, the ongoing shortage of supporting semiconductor materials such as tungsten hexafluoride further restricts the output growth of high-end wafer products.
“AI computing demand will remain the core growth engine for the semiconductor wafer market throughout 2026 and 2027,” said a senior industry analyst from SEMI. “The imbalance between wafer supply and chip demand will not be fully relieved until the large-scale new wafer fabs complete mass production in 2027. Manufacturers need to balance capacity expansion risks and long-term market demand to avoid overcapacity risks after the AI demand boom peaks.”
Looking ahead to the second half of 2026, the semiconductor wafer industry is expected to maintain an upward market trend. Continuous iteration of AI servers, automotive electronic upgrades and innovation in consumer electronics will sustain steady demand for both advanced and mature-node wafers, supporting continuous prosperity of the global upstream semiconductor material chain.
