Chipmakers including TSMC embark on a $120B investment spree across Taiwan, with 20 new fabs ready or in the works, dwarfing planned investments in US and Japan

Context & Ripple Effects
This $120B, 20-fab buildout across Taiwan is the home-market sequel to TSMC's $100B three-year capacity plan announced in April 2021 — and it lands just as the first overseas counterweights are being laid: the Arizona investment that would later triple to $40B and a TSMC-Sony image-sensor joint venture in Kumamoto. The headline comparison matters: even with US and Japan projects on the table, the bulk of new capacity is being committed where TSMC's supplier ecosystem already sits.
First-order effects
- Taiwan's fab construction ecosystem — equipment suppliers, contractors, and engineering labor — absorbs the largest single share of global foundry capex announced at that point, while TSMC's announced US and Japan sites remain a fraction of the Taiwan total.
Second-order effects
- Host governments have to bid harder to shift the balance: Japan's Kumamoto joint venture with Sony and the later US pledges — including TSMC's additional $100B for four more Arizona fabs tied to tariff-free chip sales — are the direct responses to Taiwan's gravitational pull on capacity.
Third-order effects
- The pattern points to a two-track industry structure: leading-edge capacity keeps concentrating in Taiwan even as geopolitical pressure and tariffs push duplicate fabs abroad, meaning diversification adds resilience at the margin without displacing the center of gravity.
The trend: Foundry capex is scaling worldwide, but Taiwan's home-base share keeps growing faster than the US and Japan alternatives, making subsidy-backed overseas fabs a hedge rather than a rebalancing.
