Foundry capacity underutilised but revenues and market share growing

Foundry manufacturing capacity continues to grow and is projected to reach 15.25 million wpm by 2031. The CAGR should be 4% from 2025 to 2031

However, over-investment in manufacturing capacity saw foundry utilisation drop to 73% in 2025, with forecasts that utilisation may remain between 70% and 75% over the coming years.

TSMC increased its market share to approximately 32% of global semiconductor manufacturing revenue in 2025 and 68% of the foundry market.

China is rapidly expanding capacity and could have 30% of global foundry capacity by 2031.
