Tepper has Just Made 57 Million Dollars from this Unexpected AI Deal

David Tepper, billionaire and hedge fund manager of Appaloosa Management, is quietly reaping big profits this summer. While Nvidia attracts media attention, his bolder, low-profile position in Taiwan Semiconductor Manufacturing Co. (TSM) has risen by nearly 25% in less than three months, bringing him about 57 million dollars “on paper.”

Appaloosa’s latest 13F filing shows that as of June 30, 2025, Tepper held 1.02 million TSM shares — worth about 232 million dollars. By September 23, the price had jumped to 282.71 dollars, rewarding his bold decision to add 755,000 shares during the second quarter (+280%).

TSM’s rise is driven by relentless demand for advanced AI chips, making it a key player in the global semiconductor supply chain and a good example of Tepper’s ability to spot less obvious opportunities.

While TSM dominates attention, Tepper’s position in Nvidia also contributes to his summer gains. He holds 1.75 million Nvidia shares, which climbed from $157.99 on June 30 to $178.43 as of September 23 — generating about 35.8 million dollars in profit.

The combined investments in these two AI assets bring Tepper nearly 93 million dollars in profit in less than three months — demonstrating the value of mixing big names and “hidden gems.” Tepper’s approach highlights his ability to balance risk and reward. By combining stars like Nvidia with critical but less-discussed players like TSM, he achieves significant gains while navigating the complex chip market.

For investors following the development of artificial intelligence, Tepper’s actions are a reminder that sometimes the most profitable trades come from assets that are not in the spotlight.
