1. Industry Overview
Since the start of 2026, the global semiconductor silicon wafer market has undergone its most profound structural adjustment in more than three years. Following the cyclical downturn of 2023‒2024, the wafer market began a gradual recovery in the second half of 2025 and, by Q3 2026, has entered a new upward cycle.
Key Signal: Global silicon wafer shipments reached 3,740 million square inches (MSI) in Q2 2026, up approximately 8.2% year-on-year. Capacity utilization for 12-inch (300mm) wafers recovered to over 92%, while 8-inch (200mm) utilization reached 88%.
2. A Full-Scale Price Increase Cycle
2.1 The Price Transmission Chain
Q2‒Q3 2026 witnessed an unprecedented wave of price hikes across the wafer industry:

New contract prices up another 10%+; 6-inch / 8-inch followed suit |
2.2 Drivers Behind the Price Increases
This round of price increases differs markedly from previous cycles:
- Driver 1 - Explosive AI/HPC demand. TSMC's continued expansion of CoWoS advanced packaging capacity has fueled strong demand for 12-inch silicon interposers and SOI wafers, leaving high-end wafers in short supply.
- Driver 2 - Accelerated memory recovery. Samsung, SK hynix and Micron are running at full capacity utilization; their purchases of 12- inch polished and epitaxial wafers grew more than 15% year-on-year in Q2 2026.
- Driver 3 - Sustained growth in power devices and MEMS. Rising EV penetration combined with industrial automation demand has kept 8-inch wafer demand resilient. STMicroelectronics, Infineon and other IDMs continue to run their 8-inch lines at high utilization.
- Driver 4 - Raw material cost pass-through. Prices of high-purity polysilicon and electronic-grade gases have risen since late 2025, pressuring wafer makers' gross margins and making price increases inevitable.
3. The Global Wafer Landscape Is Being Reshaped
3.1 Japanese Manufacturers Dominate Supply
Shin-Etsu and SUMCO together hold approximately 50% of the global silicon wafer market, with an especially strong position in high-end 12- inch wafers. Both companies continued capacity expansion in 2026. Global market share distribution:
-
Shin-Etsu
28%
-
SUMCO
22%
-
GlobalWafers
17%
-
Siltronic
12%
-
Zing Semi
5%
3.2 Domestic Substitution Accelerates in China
Key Trend: The self-sufficiency rate of Chinese-made silicon wafers is rising rapidly. Domestic 12-inch wafer capacity is expected to reach 1.5 million wafers/month in 2026, with the self-sufficiency rate climbing from about 15% in 2023 to over 25%.

4. Supply-Demand Outlook: 2026H2‒2027
4.1 Short Term (2026H2)
- 12-inch wafers: Capacity utilization and prices will keep rising. The demand pull from AI chips is still in its early stages; as CoWoS capacity doubles, the boost to 12-inch wafer demand will become more evident in Q4.
- 8-inch wafers: Automotive-grade and industrial-grade demand remains stable, but the strength of consumer electronics recovery needs continued observation.
- 6-inch and below: Overall demand is flat, affected by the substitution effect of third-generation semiconductors (SiC/GaN) and diverging demand for traditional power devices.
4.2 Medium Term (2027 Outlook)
Multiple brokerages (CITIC, Huatai, Tianfeng) forecast:
The global silicon wafer market is expected to exceed USD 16 billion in 2027, with a 2026‒2028 CAGR of approximately 8‒10%. The share of 12-inch wafers will rise from the current 68% to over 72%.
4.3 Risk Factors to Watch
- Geopolitical risk: U.S. export controls on semiconductor equipment to China continue to tighten. Since late 2025, restrictions on
- advanced-process equipment have been further expanded, posing challenges to equipment procurement for domestic 12-inch wafer lines.
- Inventory cycle volatility: Downstream fabs continued to draw down wafer inventories in Q2‒Q3 2026, but a slowdown in inventory restocking is possible if end demand falls short of expectations.
- Exchange rate volatility: With the Japanese yen remaining weak, Japanese wafer makers enjoy a cost advantage in international competition, putting price pressure on Chinese manufacturers.
5. Impact and Recommendations for SiBranch Customers
As a professional silicon wafer supplier, SiBranch Microelectronics advises customers to focus on the following:
1. Lock in Long-Term Supply Early
During a price increase cycle, customers with steady consumption are advised to lock in 6‒12 month contract prices with suppliers as soon as possible to avoid spot market volatility.
2. Pay Attention to Dummy/Test Wafer Supply
In an upcycle, high-end prime wafer capacity is prioritized for IDMs and large foundries. Small and mid-sized packaging/test houses can leverage the cost advantages of quality test wafers and reclaimed wafers; SiBranch can provide full alternative solutions.
3. Plan Diversified Product Lines
Beyond standard wafers, demand for differentiated products such as SOI wafers, thermal oxide wafers and metal-coated wafers is also growing. Customers are advised to plan diversified product portfolios in advance.

6. Conclusion
The silicon wafer market in 2026 is transitioning from "oversupply" to "structural shortage." AI-driven high-end demand will be the core engine of industry growth over the next 2‒3 years, while against the backdrop of geopolitical competition, the build-up of self-sufficiency in China's silicon wafer industry is entering a critical phase.
For every participant in the supply chain, the keys to winning will be grasping the rhythm of this cycle, securing supply-side resources ahead of time, and pursuing opportunities in differentiated products.
