Taiwan Semiconductor Manufacturing Company Limited (TSM) vs UnitedHealth Group Incorporated (UNH)

Taiwan Semiconductor Manufacturing Co. (TSMC) is the world’s largest pure-play semiconductor foundry, holding roughly 70% market share in 2025. Founded in 1987 as a joint venture between Philips, the Taiwan government, and private investors, the company listed in Taiwan in 1994 and later launched its US ADR in 1997. TSMC’s vast scale and advanced manufacturing capabilities support strong operating margins, even within the highly competitive foundry industry. The ongoing shift toward the fabless semiconductor model has also provided meaningful growth tailwinds. Its distinguished customer base includes Apple, AMD, and Nvidia, which rely on TSMC’s leading-edge process technologies for their chip designs. The company employs more than 83,000 people.

UnitedHealth Group Incorporated is among the world’s largest private health insurers, providing medical benefits to roughly 51 million members globally as of December 2025, including about 1 million outside the United States. A leading provider of employer-sponsored, self-directed, and government-supported health plans, the company has built substantial scale in the medical insurance market. In addition to its core insurance operations, UnitedHealth’s Optum businesses expand its reach across healthcare services, spanning pharmacy benefits, outpatient care, and analytics for affiliated organizations and third-party clients.
