Taiwan Semiconductor Manufacturing Corporation (TSM +2.30%) controlled 72% of global semiconductor foundry revenue in Q4 2025, according to data from TrendForce. The company generated $35.9 billion in foundry revenue that quarter, more than 11 times more than its closest competitor.
No other chipmaker comes close. Samsung (SSNLF +0.00%) ranked second with 6.5% of global foundry revenue in Q4 2025, followed by SMIC at 5.0% and UMC [NYSE: UMC] at 4.0%.
For investors, the market concentration in semiconductor manufacturing is both a risk and an opportunity. To help break down stocks in the sector, The Motley Fool has a guide to the best semiconductor stocks.
TSMC's share of global foundry revenue rose from 62.8% in Q1 2024 to 72.2% in Q4 2025, per TrendForce. Over the same period, Samsung's share fell from roughly 10.5% to 6.5%.
Diverging fortunes among semiconductor manufacturers are driven by a number of factors, including:
Three other manufacturers, GlobalFoundries (GFS +1.47%) at 3.3%, HuaHong Group at 2.5%, and UMC at 4.0%, each hold modest but stable global revenue shares.
A handful of other chipmakers account for roughly 7% of global semiconductor manufacturing revenue, including Intel (INTC +4.36%). 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.
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.
The data points to a market consolidating around a single dominant manufacturer. For investors, that means TSMC is the clearest expression of the semiconductor foundry opportunity, but the sector's risks and TSMC's risks are largely the same.
