TAIPEI (Taiwan News) — Contract chipmakers in Taiwan are forecasted to increase their global market share by revenue to 66% this year, TrendForce reported on Monday (April 25).

Taiwanese contract chipmakers are expected to increase their share of the contract business by 2%, up from 64% in 2021, the research firm said. Taiwan Semiconductor Manufacturing Co. (TSMC) is forecasted to grow its market share to 56% this year, up from 53% last year, while United Microelectronics Corp. will maintain its 7% share.

Meanwhile, Samsung Electronics and other South Korean chipmakers are expected to lose 1% of market share, dropping to 17%. Chinese chipmakers, led by Semiconductor Manufacturing International Corp., are expected to increase their market share by one point, putting it at 8%, according to TrendForce.

TrendForce noted that 8-inch and 12-inch foundries are currently dominated by 24 fabs in Taiwan, followed by those in China, South Korea, and the United States. Taiwan is also currently building six new chip plants, while China is building four and the U.S. three. 

Due to Taiwanese foundries having plans to expand in China, the U.S., Japan, and Singapore and other competitors expanding production, Taiwan’s market share of foundry capacity is expected to drop slightly in 2025. By that year, the country is forecasted to control 44% of global foundry capacity and around 58% capacity for advanced processes (16 nanometers and below).
