Billionaire David Tepper actively increased his investments in artificial intelligence companies in the second quarter of 2025. His hedge fund Appaloosa boosted positions in Amazon, Nvidia, Taiwan Semiconductor, and Micron, while also opening a major new position in Intel.

According to the report, the stake in Amazon rose by 7.57% to more than $592 million, Nvidia by 483% with the purchase of 1.45 million shares, and Taiwan Semiconductor by nearly 280%. In Intel, the fund bought 8 million shares, making it the largest new position of the quarter. In addition, investments in Micron more than doubled.

Wall Street analysts believe Micron has the greatest growth potential among these stocks: its share price is projected to increase by around 29% over the next year, with Rosenblatt Securities setting a target implying more than 70% upside. Optimism is linked to strong demand for DRAM memory and the company’s attractive valuation.

Meanwhile, Amazon and Nvidia remain favorites for long-term investments: Amazon maintains leadership in cloud services and continues to grow its e-commerce business, while Nvidia dominates the AI chip market with record demand for its Blackwell GPUs.
