TSMC Approves Fresh $20 Bn for Arizona Chip Plant, $31.3 Bn for Future Fabs

At a recent board of directors meeting in Taiwan’s Hsinchu, Taiwan Semiconductor Manufacturing Company (TSMC) approved more than $51 billion in new investments, including a $31.3 billion capital appropriation and a further $20 billion injection into its wholly-owned Arizona subsidiary. 

This comes as the world’s largest contract chipmaker accelerates its global expansion plans. The company said the $31.3 billion allocation will support advanced technology capacity, fab construction and facility systems. 

The scale of the spending highlights how aggressively TSMC is moving to secure advanced chipmaking capacity amid surging AI demand and increasing geopolitical pressure to localise semiconductor production in the United States.

TSMC said in a statement shared with AIM that the capital appropriation would help meet “long-term capacity plans based on market demand forecasts and TSMC’s technology development roadmap”.

The Arizona investment arrives as the US pushes for more domestic semiconductor manufacturing. TSMC’s Arizona operations have become central to Washington’s broader strategy to reduce dependence on Asian chip supply chains.

The board decisions also come days after reports linked Tesla’s future AI chip roadmap to US foundry expansion plans. A report published by Wccftech cited unnamed sources claiming Tesla could shift part of its AI6.5 chip production from TSMC to Intel Foundry under pressure from the Trump administration.

While TSMC made no reference to Tesla or Intel in its board resolutions, its Arizona expansion could strengthen its position in the race to build advanced AI chip production facilities in the US.

In April, Tesla CEO Elon Musk said on X that Tesla’s AI6.5 chip would “further improve performance using TSMC 2nm in Arizona”.

TSMC also recently approved its Q1 FY26 financial statements during the meeting. The company reported consolidated revenue of NT$1.13 trillion and net income of NT$572.48 billion for the quarter.

In May, the giant announced a continued partnership with Applied Materials for its new EPIC Center in Silicon Valley and Sony Semiconductors to build next-generation image sensors.

Moreover, on April 28 and 29, the company sold all its shares in Arm Holdings, primarily owned by the Japanese conglomerate SoftBank Group, according to a company filing accessed by AIM.
