In a bold move that highlights a strategic pivot in tumultuous times, private investment firms belonging to some of the world's wealthiest individuals significantly increased their holdings in semiconductor and energy sectors during the first quarter of 2026. This aggressive investment strategy unfolded against the backdrop of the Iran war, which presented both challenges to data center economics and propelled oil prices skyward.
Led by prominent figures such as David Tepper, Stanley Druckenmiller, and George Soros, these elite family offices identified opportunities amidst geopolitical uncertainty. For instance, David Tepper's Appaloosa Management substantially boosted its stake in Micron Technology by 11%, elevating it to his firm's second-largest holding at $562.5 million. Appaloosa also expanded its position in Taiwan Semiconductor by 18% to $448.6 million and initiated a new $179 million investment in Sandisk.

Similarly, Stanley Druckenmiller's Duquesne Family Office revealed a fresh $24 million stake in Sandisk and a notable $161 million position in Broadcom. George Soros's namesake firm, Soros Fund Management, amplified its Nvidia holdings by 61%, reaching $187 million and securing a spot among its top 10 investments. These calculated maneuvers have proven prescient, with semiconductor stocks experiencing a remarkable rally in recent months.
The returns have been swift and substantial: Sandisk and Micron shares have soared by approximately 50% and 60% respectively over the past 30 days. While Nvidia, Broadcom, and Taiwan Semiconductor saw more modest gains recently, their cumulative increases since the end of March have been significant, with Broadcom up 35%, Taiwan Semiconductor 19%, and Nvidia around 28%.
However, not all decisions involved accumulation. Duquesne Family Office judiciously locked in profits by divesting from Entegris and ON Semiconductor last quarter. Appaloosa also reduced its Nvidia stake by 13%, though it remains a substantial $257 million position.
The approach to energy stocks showcased a divergence among billionaire investors. As the Iran war pushed oil prices higher, Appaloosa more than doubled its investment in Vistra Corp to $304 million. In contrast, Michael Platt’s BlueCrest Capital Management exited its $103 million Vistra position. Duquesne, on the other hand, dramatically cut its stake in fuel cell manufacturer Bloom Energy by 82% to $89 million but simultaneously increased its holding in Argentinian oil and gas producer YPF Sociedad more than fivefold to $150 million, making it the fifth-largest institutional shareholder.
Amid a burgeoning fuel crisis for airlines, some family offices opted to exit their positions entirely. Appaloosa sold its stakes in American Airlines, Delta Air Lines, and United Airlines, while Duquesne also divested its holdings in Delta, reflecting a cautious stance on the aviation sector.
