TSMC has announced plans to invest at least $100 billion in U.S.-based semiconductor manufacturing over the next four years, significantly expanding its production footprint. President Donald Trump confirmed the investment during a press conference, stating that the cash infusion will fund the construction of several new facilities in Arizona. TSMC Chairman and CEO C.C. Wei emphasized that the company will focus on producing AI chips to support ongoing advancements in artificial intelligence.
This latest investment follows TSMC’s previous pledge of $65 billion toward U.S. fabrication plants, supplemented by $6.6 billion in CHIPS Act grants. With the new funding, TSMC’s total commitment to the U.S. semiconductor industry reaches approximately $165 billion. Trump noted that the U.S. has long urged TSMC to relocate more of its production stateside, citing concerns over the company’s dominance in chip manufacturing and the critical role advanced semiconductor packaging plays in AI development.
As part of his administration’s push to revitalize domestic chip production, Trump has proposed imposing tariffs on foreign semiconductor manufacturing and suggested restructuring the CHIPS Act. However, industry analysts warn that such measures could disrupt AI progress in the U.S. Daniel Newman, CEO of the Futurum Group, suggested that TSMC’s investment may be strategically linked to a delay in tariffs or other regulatory incentives. He described the commitment as a potential diplomatic win, reinforcing U.S. efforts to bolster its semiconductor supply chain.
While TSMC operates multiple U.S. facilities, including an Arizona factory that began mass production last year, its most advanced semiconductor plants remain in Taiwan. With geopolitical tensions rising, the U.S. government has reportedly encouraged TSMC to take over Intel’s struggling domestic chip plants, further strengthening American semiconductor infrastructure.
Trump has increasingly spotlighted large-scale technology investments, appearing alongside tech executives to promote U.S. infrastructure projects. Recent announcements include OpenAI and SoftBank’s half-trillion-dollar AI data center pledge and Apple’s $500 billion commitment to expanding U.S. manufacturing. While these initiatives mark a shift toward domestic production, industry experts remain skeptical about their feasibility and long-term execution.
