Billionaire investor David Tepper's hedge fund, Appaloosa Management, significantly increased its position in Taiwan Semiconductor Manufacturing (TSMC) during the second quarter of 2026. According to a quarterly report filed with the SEC, the firm's holdings in the chipmaker grew by over 24%, from 1.33 million to 1.65 million shares. This raised the total reported value of the stake to approximately $788 million as of June 30, 2026.
This portfolio adjustment, revealed in a filing that reflects trades made up to six weeks prior, comes as TSMC reported exceptionally strong Q2 earnings, driven by high demand for its advanced chips used in artificial intelligence. While the filing does not state a specific motive, the increased investment aligns with a broader trend of Tepper consolidating positions in key AI infrastructure companies.
