en.Wedoany.com Reported - On July 1 local time, U.S. President Donald Trump said in an interview with the media before leaving Joint Base Andrews in Maryland that Taiwan is doubling the scale of a wafer fab under construction in Arizona, and predicted that the U.S. chip market share could reach 50% during his term.
Trump stated that new chip factories will come online in the coming year, and chip manufacturers from Taiwan—including industry leader TSMC—are ramping up investments in the U.S.
"The world's largest chip-making company (TSMC), they are building a plant in Arizona, and just announced they will double its scale," Trump said. "By the time I leave office, we might have 50% of the chip manufacturing market. Do you know how much we have now? Nothing."
Trump also emphasized that U.S. employment data has hit record highs, and "this is happening even before these factories come online."
It remains unclear whether Trump's statement that "TSMC will double the scale of the wafer fab under construction in Arizona" refers to new investments on top of previously announced commitments or an expansion plan already disclosed.
TSMC declined to comment on Trump's remarks. Gong Mingxin, head of Taiwan's economic affairs department, said in an interview before presiding over a business briefing on July 2 that, based on TSMC's publicly announced plans, the island has a total of 16 fabs, including those already built and those in subsequent planning, plus CoWoS advanced packaging capacity. "No matter how many factories the U.S. builds, it won't reach that number."
TSMC has previously announced several major investment plans in the U.S. After the U.S. CHIPS Act was signed in 2024, TSMC announced a total investment plan of $65 billion, including the construction of three wafer fabs in Arizona.
In March 2025, TSMC announced an additional $100 billion investment, bringing its total investment in the U.S. to $165 billion. The new investment includes building three advanced process wafer fabs, two advanced packaging plants, and a next-generation technology R&D center in Phoenix.
At the time, TSMC said this was the largest single foreign direct investment in U.S. history, expected to create approximately 40,000 construction jobs over four years and tens of thousands of high-paying chip manufacturing and R&D positions.
