TSMC Expands U.S. Investment to $265 Billion as AI Supply Chains Shift

Taiwanese technology companies are expanding overseas AI-server supply chains in the United States and Southeast Asia.

TSMC (2330) announced an additional $100 billion in U.S. investment in July, bringing its total planned U.S. investment to $265 billion. The company also plans four additional advanced fabrication plants, which would bring its U.S. facility count to 12.

The United States is projected to account for 40% of Taiwan-based companies’ AI-server capacity by 2030, up from 23% in 2026. Taiwan’s share is projected to decline from 47% to 30% over the same period.

Taiwan’s major companies had announced a combined $55 billion in U.S. investment plans. Excluding TSMC, about 20 semiconductor, server and related companies had announced roughly $35 billion in investment through May.

Server manufacturers are adding capacity in the United States. Quanta Computer (2382) received approval to invest $973 million through a Tennessee subsidiary to assemble computers, servers and peripheral equipment. Wistron (3231) received approval for $150 million to expand printed circuit board assembly, while Inventec (2356) received approval for $110 million to support U.S. server assembly.

Southeast Asia is attracting investment in components used in AI-server systems. 奇鋐 (3017) plans to invest NT$7.78 billion in a new Vietnam plant, while 台燿 (6274) plans to spend 7.79 billion Thai baht, or about $231.8 million, to expand its Thailand subsidiary with a new facility and additional equipment.

日月光投控 (3711) purchased approximately NT$1.26 billion in production equipment and agreed to acquire a factory for approximately NT$2.15 billion through its Singapore subsidiary. 訊芯-KY (6451) also plans to invest up to $65 million in a Vietnam semiconductor production line.

Taiwan’s imports from ASEAN countries totaled $70.4 billion in the first eight months of 2026, a 75.4% increase from a year earlier. The investment and trade figures point to a division of labor in which the United States takes a larger role in wafer manufacturing and server assembly, while Southeast Asia expands in circuit boards, cooling components, and semiconductor testing and packaging.
