AI Bubble Concerns Rise! TSMC Doubles Down with $100 Billion U.S. Investment – Foreign Media Praises: Long-Term Demand Assurance

The artificial intelligence (AI) boom continues to heat up, but market concerns have recently emerged over whether tech giants' massive investments in AI infrastructure may be leading to overinvestment risks. In response, U.S. investment media The Motley Fool highlights that TSMC, the world's leading semiconductor foundry, has recently announced an additional $100 billion investment in its Arizona fabrication plant—this move is seen as a strong vote of confidence in the long-term demand for AI.

The report analyzes that investors have held divergent views on AI infrastructure investments in recent months, with some expressing concern that cloud giants such as Microsoft, Amazon, Alphabet, and Meta have poured enormous capital expenditures into AI without yet fully translating these into tangible returns. However, TSMC, as the global leader in advanced chip manufacturing, has chosen to significantly expand its U.S. investment, signaling the company's high confidence in future chip demand. Such a massive capital expenditure decision would not be made without strong underlying demand expectations.

The report notes that TSMC accounts for approximately 72% of global foundry revenue, significantly outpacing competitors in both technological capability and production scale. As a result, it has become the primary manufacturing partner for the world's top AI chip design companies. Even as the market leader in AI chips remains uncertain, most high-end chips are still likely to require TSMC's manufacturing capabilities.

TSMC Chairman Mark Liu stated during the company's recent Q2 earnings call that current AI demand remains very strong and is expected to continue through 2029 to 2030, giving rise to an entirely new 'AI industry.' He emphasized that AI is not a short-term trend but a transformative force that will integrate into daily life and profoundly impact the global economy and industrial structure.

The media report adds that Chairman Liu maintains close collaboration with global AI cloud service providers and chip designers, giving him deep insight into end-market demand. His assessment is therefore considered highly credible. TSMC's latest investment expansion is thus viewed as a strong endorsement of AI's long-term growth trajectory.

Furthermore, while many major AI-related stocks have faced significant corrections this year, TSMC's stock has shown relative resilience, rising nearly 50% year-to-date. The report attributes this to the market's recognition of TSMC's pivotal role in the AI supply chain.

However, the media also cautions investors that holding TSMC stock now comes at a premium. The company's current forward P/E ratio is around 28x—not cheap by traditional standards. Yet, given TSMC's historical growth performance and the long-term potential unlocked by the AI industry, the valuation is not necessarily excessive. The report concludes that as long as AI infrastructure investment continues, TSMC will remain one of the most direct beneficiaries.
