Taiwan Semiconductor Manufacturing (TSMC) will invest at least $100 billion over the next four years to expand processor manufacturing in the U.S., former President Donald Trump announced, according to WSJ.

TSMC CEO C.C. Wei stated that the company plans to produce AI chips to support artificial intelligence advancements.

Trump called the investment a “tremendous move” and emphasized that TSMC is “the most powerful company in the world.” With this new initiative, TSMC’s total U.S. investments will reach $165 billion, funding the construction of five new factories in Arizona.

On January 21, Trump announced $500 billion in private sector investments for AI infrastructure. OpenAI, SoftBank, and Oracle will collaborate on a joint venture named Stargate.

TSMC’s decision to expand, as a key supplier of semiconductors for U.S. AI firms, aligns with Trump’s efforts to establish the U.S. as a global AI hub. The former president has repeatedly called for bringing chip manufacturing back to the U.S., citing it as a matter of economic and national security.

In 2020, TSMC committed $12 billion to build its first U.S. chip factory in Arizona. That investment later increased to $65 billion, leading to the construction of three plants. The company also secured $6.6 billion in subsidies from the U.S. Department of Commerce.

In October 2024, reports surfaced about OpenAI partnering with Broadcom and TSMC to develop a proprietary AI chip.
