TSMC chairman C.C. Wei and President Donald Trump announced at the White House on 3 March 2025 that TSMC would invest at least a further $100 billion in Arizona. The plan adds three fabs, two advanced packaging facilities and an R&D centre to the $65 billion already committed, for a total of $165 billion.

Why it matters

US chip buyers, including AI accelerator designers, gained a path to leading-edge production and packaging on US soil, and Taiwan’s largest firm moved more capacity offshore.
