TSMC has confirmed a $100 billion investment to add four more fabs to its Arizona facility, following record second-quarter earnings. The company's supply chain partners are expected to contribute about $30 billion of the total. The expansion builds on $165 billion already invested in the site.

Investment Scale

TSMC confirmed the $100 billion package on July 16, 2026, following earlier reports of the plan. The total includes $30 billion from supply chain partners, marking a major push for supply chain independence. The company had already invested $165 billion in its Arizona campus.

Land and Timeline

In January, TSMC purchased an additional 900 acres near its Phoenix site. The new fabs will take multiple years to complete, with capital expenditures spread over nearly a decade. TSMC approved a record $45 billion capex for 2026 alone, indicating the Arizona buildout may take half a decade or more.

Simultaneous Taiwan Investments

Despite the U.S. expansion, TSMC continues to invest heavily in Taiwan. The company faces challenges including skilled labor shortages and equipment procurement. The dual investment strategy reflects TSMC's effort to balance global diversification with domestic capacity.
