TSMC reached a $1 trillion market capitalization in July 2025.
Taiwan Semiconductor Manufacturing Company is the world’s leading dedicated semiconductor foundry. Unlike an integrated chipmaker that designs and manufactures many of its own branded processors, TSMC primarily manufactures chips designed by other companies, including major technology firms.
Its valuation has been supported by demand for advanced process technologies used in smartphones, high-performance computing, graphics processors, and artificial-intelligence systems. TSMC’s manufacturing scale and relationships with leading chip designers make it a central company in the global semiconductor supply chain.
TSMC was founded in 1987 by Morris Chang. It helped establish the pure-play foundry model, allowing chip designers to outsource manufacturing rather than build their own fabrication plants. Market capitalization still changes daily, so the trillion-dollar milestone describes a point reached during trading rather than a permanent value.
