What has provided the biggest tailwind for the stock market over the last three years? Anyone who has paid attention can easily answer that question. It's artificial intelligence (AI).
One investor who has definitely noticed how AI has buoyed the stock market is David Tepper. But the billionaire hedge fund manager hasn't just watched from the sidelines; he has invested heavily in AI stocks. Tepper bought five AI stocks in the second quarter of 2025. And Wall Street thinks one of them could soar the most.
Amazon (NASDAQ: AMZN) ranks as the third-largest holding in the portfolio of Tepper's Appaloosa hedge fund. Appaloosa added another 7.57% to its stake in the e-commerce and cloud services giant in Q2. At the end of the quarter, Tepper's position in Amazon was valued at more than $592 million.
Appaloosa bought 1.45 million additional shares of Nvidia (NASDAQ: NVDA) in Q2. This purchase boosted the hedge fund's stake in the GPU maker by more than 483%. It also more than offset Tepper's sale of 380,000 Nvidia shares in the first quarter of 2025.
Tepper significantly increased his hedge fund's holding in Taiwan Semiconductor (NYSE: TSM) in Q2 as well. He bought another 755,000 shares of the chip stock, boosting Appaloosa's position by nearly 280%.
Intel (NASDAQ: INTC) takes the prize as Tepper's biggest new AI stock added to Appaloosa's portfolio last quarter. The billionaire bought 8 million shares of the chipmaker in Q2 -- before the U.S. government's move to take a 10% stake in Intel.
Micron Technology (NASDAQ: MU) isn't a large holding for Appaloosa. However, the hedge fund owns a lot more of the memory and storage solutions company's stock now. Tepper more than doubled Appaloosa's stake in Micron in Q2.
Unlike the Trump administration, Wall Street is decidedly bearish about Intel. The consensus 12-month price target for the stock is more than 10% below the current share price. Only two of the 44 analysts surveyed by LSEG in August recommended Intel as a "buy" or "strong buy."
Analysts are more upbeat about Nvidia. The average price target for the stock reflects an upside potential of around 7%. However, look for upward revisions to analysts' views of Nvidia if the company delivers a significantly better-than-expected (or worse-than-expected) fiscal 2026 Q2 update.
