TSMC: Record Quarterly Profits Threatened by US Tariffs
The semiconductor industry has never been more strategic than it is today. At the heart of the technological revolution, the microchip has become the new oil of the 21st century—and Taiwan Semiconductor Manufacturing Company (TSMC) is its main refinery. On Thursday, October 16, 2025, the world’s leading chip foundry announced a quarterly profit surge of 39.1%, blowing past market expectations. This historic record highlights the sector’s remarkable health, fueled by booming demand for artificial intelligence, 5G, electric vehicles, and connected devices.
But behind this financial fireworks display, a shadow looms: trade tensions between Taiwan, the United States, and China, and especially the threat of new US tariffs on Taiwanese semiconductors. These geopolitical uncertainties could slow TSMC’s growth and, by extension, disrupt the entire global tech value chain. So, what made this quarter so exceptional? What are the real risks facing TSMC and its clients? And most importantly, what does it all mean for markets, investors, and the global economy? Let’s dive into the heart of a sector in turmoil.
A Historic Quarter for TSMC
Results That Shatter Expectations
In Q3 2025, TSMC reported a net profit of $12.4 billion, up 39.1% from the same period in 2024, according to figures released Thursday and reported by Reuters. Revenue jumped 28.7% to $24.8 billion. These results, far exceeding analysts’ forecasts, are driven by sustained demand for advanced chips—especially those used in artificial intelligence, data centers, and high-end smartphones.
TSMC remains the exclusive supplier for tech giants like Apple, NVIDIA, AMD, Qualcomm, and, to a lesser extent, Intel. These companies rely almost entirely on TSMC’s Taiwanese fabs for their most advanced processors. The chip shortage that rocked the auto and electronics industries from 2021 to 2023 has given way to a race for production capacity. TSMC has capitalized on this, investing heavily in new fabs in Taiwan, as well as in the US, Japan, and Germany.Growth Fueled by AI and 5G
Artificial intelligence is now the primary driver of semiconductor demand. Data centers hosting generative AI models like ChatGPT or Gemini consume massive quantities of high-end chips. Autonomous and electric vehicles, industrial robotics, smart devices—all these sectors are pushing demand higher. 5G is also playing a crucial role: every new smartphone generation requires more powerful and energy-efficient chips. TSMC is the only player capable of mass-producing 3-nanometer (nm) processors—and soon, 2 nm—a level of miniaturization its competitors can’t match. This technological edge gives TSMC a commanding competitive advantage.US Tariffs: A Sword of Damocles
A Tense Geopolitical Backdrop
For years, relations between Taiwan, China, and the United States have been at the center of global tech concerns. Taiwan, claimed by China but governed independently, is the world’s main producer of advanced chips. The US, eager to secure its supply chains, has offered incentives for TSMC to build fabs on American soil (notably in Arizona). But, according to sources cited by Bloomberg, Washington is also considering imposing tariffs on Taiwanese semiconductors to protect domestic industry and reduce dependence.
If enacted, these tariffs could reach 15–25% on certain categories of chips, according to the Wall Street Journal. Such a move would drive up the price of electronic components, directly impacting American manufacturers of smartphones, computers, servers, and electric vehicles.Direct Impact on TSMC and Its Clients
For TSMC, the stakes are twofold: maintaining competitiveness against rivals like Samsung and Intel, and keeping balanced relationships with its American clients. If tariffs are imposed, several scenarios could play out:
According to Morgan Stanley analysts, a 20% tariff on Taiwanese chips would cut TSMC’s net profit by 8–12% over a year, all else being equal. That’s a major blow for a company with a market cap north of $600 billion.
The Ripple Effect on Tech and Global AI
A Value Chain Under Pressure
TSMC is both the weakest and strongest link in the high-tech industry. Without its chips, there’s no iPhone, no PlayStation, no Tesla Full Self-Driving, no data centers to power generative AI. Any disruption in supply or spike in costs would trigger a domino effect:Companies like Apple, Microsoft, Amazon, and Google—together accounting for over 50% of the Nasdaq’s market cap—are directly dependent on TSMC. A crisis at TSMC would be a crisis for all of Silicon Valley.
AI: The Biggest Winner… and Potential Loser
Artificial intelligence is both TSMC’s growth engine and its Achilles’ heel. AI data centers require ever more powerful chips, most of which are made by TSMC. Gartner estimates that the global AI semiconductor market will hit $120 billion in 2025—nearly double its 2022 size.But if US tariffs come into play, the cost of the intensive computing needed for AI would rise sharply. Startups and industry giants alike would have to absorb the increase or slow their expansion. In the long run, this could dampen AI adoption in sectors like industry, healthcare, finance, and transportation.
TSMC’s Strategies for Navigating Geopolitical Risks
Geographic Diversification
Aware of the risks, TSMC is accelerating its geographic diversification strategy. The company is building a mega-fab in Phoenix, Arizona, with total investment topping $40 billion. Other sites are in development in Japan (with Sony) and Germany (with Bosch and Infineon). The goal: reduce dependence on Taiwan and secure supply for Western clients.
These investments are backed by public subsidies (the US CHIPS Act, plus European and Japanese incentives), but they take time. Significant production outside Taiwan isn’t expected before 2026–2027. Until then, most output remains concentrated on the island, leaving TSMC—and its clients—exposed to heightened geopolitical risk.Technological Innovation and Strategic Alliances
TSMC is also betting on innovation to maintain its lead. The company plans to launch 2 nm production as early as 2026, a technology that will help it stay ahead of Samsung and Intel. At the same time, it’s strengthening partnerships with tech giants and governments alike to secure supply chains for raw materials (silicon, rare gases, lithography equipment). Alliances with the US are crucial. TSMC is working closely with the US Department of Defense to secure production of critical chips for national security—a way to demonstrate loyalty to Washington while protecting its commercial interests.Outlook and Trends for 2026
A Market Still Under Pressure
Demand for semiconductors is expected to remain strong in 2026, driven by AI, 5G/6G, electric vehicles, and industrial digitization. According to IDC, the global chip market could grow 12–15% annually through 2030. Thanks to its investments and technological edge, TSMC is well positioned to benefit. But geopolitical and trade risks aren’t going away. US-China rivalry, tensions over Taiwan, potential tariffs—all could slow TSMC’s growth and, by extension, the entire tech industry.What Are TSMC’s Clients’ Alternatives?
In the face of uncertainty, tech giants are exploring other options:
Conclusion: TSMC, Between Record Profits and Uncertainty

8. How exposed is the broader tech ecosystem to TSMC disruptions?
The article describes TSMC as both the weakest and strongest link in high tech. Without its chips, there’s no iPhone, no PlayStation, no Tesla Full Self-Driving, and no data centers powerful enough to run generative AI at scale. Disruptions—whether from tariffs, geopolitics, or supply constraints—would likely trigger delays in new product launches, slower innovation as companies postpone R&D, and higher prices for consumers. The stakes reach far beyond individual firms: Apple, Microsoft, Amazon, and Google—together accounting for over 50% of the Nasdaq’s market cap—depend directly on TSMC. In this sense, a crisis at TSMC would amount to a crisis for Silicon Valley and the global tech value chain.
9. What is TSMC doing to manage geopolitical risk?
TSMC is accelerating geographic diversification and deepening strategic alliances. It is building a mega-fab in Phoenix, Arizona, with total investment topping $40 billion, and developing sites in Japan (with Sony) and Germany (with Bosch and Infineon). These projects are supported by public subsidies (the US CHIPS Act and European/Japanese incentives) but require time to reach meaningful output. In parallel, TSMC is pushing technological innovation, targeting 2 nm production as early as 2026 to maintain its lead over Samsung and Intel. The company is also strengthening partnerships to secure supply chains for materials and lithography equipment.

10. When will production outside Taiwan become meaningful?
Despite aggressive investment in the US, Japan, and Germany, the article notes that significant production outside Taiwan isn’t expected before 2026–2027. Until then, most of TSMC’s output remains concentrated on the island, leaving the company—and its customers—exposed to geopolitical and trade risks in the near term. The diversification strategy is designed to reduce dependence on Taiwan and secure supply for Western clients, but building and ramping advanced fabs is a multi-year process. As those facilities come online, TSMC aims to balance geopolitical considerations with maintaining its technological lead, ensuring critical capacity is available closer to key end markets.
11. What alternatives do TSMC’s clients have, and are they sufficient?
Clients are exploring several options: diversifying suppliers (Samsung, Intel Foundry Services, GlobalFoundries, and even Chinese startups like SMIC), investing in more in-house chip design (still outsourced to foundries), and strategic stockpiling to buffer disruptions. However, the article stresses that none of these solutions is perfect. TSMC remains, and will remain for several years, the undisputed leader in cutting-edge nodes. Its technological dominance is so strong that even higher costs would be unlikely to dethrone it in the short term. As a result, diversification can mitigate risk at the margins, but there is no true like-for-like substitute for TSMC’s most advanced manufacturing.
12. What should investors and consumers watch heading into 2026?
Demand should remain strong, driven by AI, 5G/6G, electric vehicles, and industrial digitization. According to IDC, the global chip market could grow 12–15% annually through 2030. But geopolitical risk lingers: US–China rivalry, tensions over Taiwan, and potential US tariffs on Taiwanese chips could slow growth or raise costs. Watch TSMC’s execution on geographic diversification (Arizona, Japan, Germany), its 2 nm rollout, and any policy moves on tariffs, subsidies, or national security. For consumers, higher input costs could translate into more expensive devices or slower innovation cadence. For investors, the challenge is balancing exceptional structural growth with political and commercial risks that can affect margins, capital allocation, and the pace of AI-driven adoption.
