Apple’s chipmaking partner, TSMC, is reportedly about to announce a $100 billion investment in US-based manufacturing.

Apple’s pledge to spend $500 billion to onshore production means a boost for TSMC’s massive chip factory in Phoenix. President Donald Trump chalked up Apple CEO Tim Cook’s move to Trump’s tariff threat.

Trump said TSMC’s plans would create “many thousands” of high-paying jobs and described the production of AI chips within the US as a “matter of economic security” for the country.

TSMC announces an additional $100 billion investment in the US, expanding its total investment in Phoenix, Arizona to $165 billion. The expansion includes three new fabrication plants, two packaging facilities,

Taiwan Semiconductor Manufacturing will again expand its Phoenix complex, to a new $165 billion stake. The move aims to avoid tariffs.

The investment will go into building three new fabrication plants in Phoenix, Arizona, as well as two packaging facilities and a research center.

TAIWANESE chipmaker TSMC is expanding investment in the US because of large US customer demand, its CEO said on Thursday (Mar 6), adding that its production lines there are already fully booked for this year and the next two years.
