A handful of other chipmakers account for roughly 10% of global semiconductor manufacturing revenue, including Intel (INTC +4.89%). Once a cutting-edge semiconductor innovator and manufacturer, the American company has struggled for more than a decade and was on the verge of scaling back its manufacturing in the U.S. That prompted the Trump administration to take a 10% stake in Intel out of concern that advanced chip manufacturing would entirely leave the United States, leaving the country reliant solely on foreign firms for semiconductors necessary for national security and technological innovation.
Why semiconductor manufacturing revenue matters for investors
Market concentration in chip manufacturing cuts both ways. TSMC's commanding lead offers a degree of predictability -- its customers have built product roadmaps around its manufacturing capabilities, and switching costs are high. But concentration also means geopolitical risk is concentrated. TSMC's primary fabs are in Taiwan, which remains a source of concern for investors tracking U.S.-China tensions.
- Revenue share reflects manufacturing capability, not just market position. A company's share of foundry revenue signals which firms can produce the chips customers actually need. TSMC's 70% share reflects its ability to manufacture at the most advanced nodes, 3nm and below, that power AI chips, smartphones, and data center hardware.
- The gap between TSMC and the field has widened, not narrowed. TSMC's share grew roughly 8 percentage points between Q1 2024 and Q3 2025, per TrendForce. Samsung, the only other company with ambitions at the leading edge, lost ground over the same period.
- Intel's foundry position remains small but strategically significant. Intel generated $223 million in foundry revenue in Q3 2025, just 0.5% of the global total, per TrendForce. The U.S. government took a 10% stake in Intel to preserve domestic chip manufacturing capability, which suggests that investors can't ignore geopolitics when building semiconductor investment theses.
The data points to a market that is consolidating around a single dominant manufacturer. For investors, that means TSMC is the clearest expression of the semiconductor foundry opportunity, but it also means the sector's risks and TSMC's risks are largely the same.
