TSMC Warns Profit Margins Will Be Squeezed for Years by Overseas Expansion

TSMC, the world's leading chipmaker, projects its profit margins will be squeezed for several years as it accelerates factory construction outside Taiwan. The forecast comes amid political pressure from US President Donald Trump to produce advanced semiconductors domestically, directly raising operating costs and pressuring profitability. According to a report by Kai Nicol Schwarz of CNBC on July 22, 2026, TSMC has announced $200 billion in investment for US manufacturing since Trump returned to power in 2025. The figure reflects the company's massive commitment to meet Washington's demand for chip supply chain independence, especially for artificial intelligence and military technology. The projected margin dilution will last for several years as production capacity ramps up at overseas plants.

TSMC has long been known as a global leader in chip fabrication with high profit margins, thanks to cost efficient concentration of production in Taiwan. However, expansion into countries with higher labor, construction, and regulatory costs, such as the US, changes that economic calculus. Pressure from the Trump administration to produce American made AI chips is a key driver behind the expansion. Since returning to office, Trump has pushed policies prioritizing domestic production to reduce reliance on Taiwan, which is seen as geopolitically vulnerable. TSMC, as the main chip supplier for companies like Apple, Nvidia, and AMD, had little choice but to comply. The $200 billion investment includes building several advanced fabrication facilities in the US, including in Arizona, which has begun phased operations.

The project is one of the largest foreign investments in US manufacturing history, but it also carries significant cost burdens for TSMC. Analysts estimate that building a fab in the US can cost two to three times more than in Taiwan, due to differences in wages, environmental compliance, and supporting infrastructure. The impact on TSMC's profit margins is already visible. In its latest financial report, the company recorded a decline in gross margin compared to the previous period, even though revenue continued to grow thanks to surging demand for AI chips. TSMC management stated that the margin decline is temporary and will be offset by higher production volumes in the future, but they acknowledged that the transition period could last several years.

From an industry perspective, TSMC's move reflects a major shift in the global semiconductor manufacturing landscape. For decades, Taiwan has been the world's most efficient chip production hub, with TSMC controlling over 50% of the global foundry market. However, geopolitical pressures and Western countries' desire to secure strategic chip supplies have forced the company to diversify its production locations. The US government, through the CHIPS Act and other policies, has provided fiscal incentives to attract semiconductor investment. However, the actual costs incurred by TSMC far exceed the subsidies received. The company also faces challenges in recruiting skilled labor in the US, where the talent pool is still limited compared to Taiwan's mature semiconductor ecosystem.

Market reaction to the margin dilution forecast has been muted so far. TSMC shares listed on the New York Stock Exchange have shown mild volatility, but analysts have not reacted significantly because the projection was already anticipated. Investors are more focused on TSMC's long term prospects as a primary supplier of AI chips, demand for which is expected to continue growing despite cost pressures. Going forward, TSMC is expected to balance political pressure to produce in the US with the need to maintain profitability. The company will likely pass some cost burdens to customers through wafer price increases, as it has done in recent years. However, this strategy has limits because customers like Apple and Nvidia also have strong bargaining power.

The projected multi year margin dilution is a test of TSMC's historically efficient business model. If successful, this global expansion could become a blueprint for other semiconductor companies looking to follow a similar path. But if it fails, it could weaken TSMC's position amid fierce competition from Samsung and Intel, which are also aggressively building production capacity in the US. TSMC's situation underscores the broader tension between national security driven reshoring and corporate profitability. While the US seeks to secure its chip supply chain, the economics of semiconductor manufacturing remain heavily skewed toward Taiwan. The coming years will reveal whether TSMC can maintain its technological edge and financial discipline while navigating this new geopolitical reality.
