Taiwan's biggest chip and electronics firms are moving more production abroad, a shift that spreads risk for customers but chips away at Taiwan's grip on the world's most important supply chain.

• Foxconn's Young Liu says the goal now is to "make with Taiwan, not in Taiwan" — customers want factories spread across countries and governments want products built at home.
• AI demand is growing faster than Taiwan can build: TSMC's equipment spending plan for this year nearly doubled in six months.
• TSMC is building 13 plants in Taiwan and five or six overseas, roughly triple its usual pace, and still can't keep up.
• A shortage of chip substrates is a choke point, and much of the critical tooling comes from small Japanese suppliers already stretched thin.
• MediaTek's Rick Tsai frames Taiwan's edge as speed and flexibility rather than location, arguing the supply chain is already global.

Outlook: Expect more Taiwanese fabs and packaging plants announced overseas, with substrates and Japanese materials suppliers the bottleneck to watch.
