TSMC Plans $100 Billion More for US Chip Plants After AI Boom

In mid-July 2026, Taiwan Semiconductor Manufacturing Company (TSMC) announced it would invest an additional $100 billion to expand its chip production facilities in Arizona. This comes after the company reported a record 77% jump in quarterly profit, driven by surging demand for artificial intelligence chips. The total planned US investment now stands at $265 billion, a key deal for President Donald Trump, who has pushed for more domestic chip manufacturing.

The expansion aims to meet what TSMC calls an AI "megatrend," with the company also raising its sales and spending outlook. The Arizona plants are part of a broader effort to reduce reliance on Asian chip production. TSMC has now posted five consecutive record quarters, underscoring the chipmaker's dominant position in the global semiconductor market.
