TSMC shares quadruple as chipmaker widens its lead in semiconductor manufacturing

TSMC, the company that quietly manufactures the brains inside nearly every device you touch, has seen its stock nearly quadruple over the past three years. The roughly 359% three-year return tells a story that extends well beyond semiconductors, reaching into AI infrastructure, geopolitics, and the very foundations of the global tech economy. The numbers behind the dominance TSMC’s recent financial performance reads like a highlight reel. Q4 revenue climbed approximately 20% year-over-year, while profits jumped around 35%, comfortably beating market expectations. In 2025, TSMC’s revenue growth hit roughly 36%, according to Counterpoint Research. Non-TSMC foundries? They managed about 8%.

Why competitors can’t catch up TSMC’s moat is built on something deceptively simple: it makes the most advanced chips in the world, and nobody else can do it at scale. Samsung and Intel have spent billions trying to close the gap. The 36% vs. 8% growth differential tells you how that’s going. The AI connection and what it means for te...
