Private investment firms of the ultra-wealthy doubled down on chipmakers in the first quarter of 2026 despite pressures from the Iran war, according to securities filings analyzed by CNBC.
Several family offices also leaned into energy producers as the Middle East conflict drove oil prices up, though others opted to lock in their gains. David Tepper's family office Appaloosa Management raised its stake in Micron Technology by 11%, making the chipmaker its second-largest holding, at $562.5 million, at the end of March. Appaloosa also increased its stake in Taiwan Semiconductor by 18%, to $448.6 million, and disclosed a new $179 million position in Sandisk.
Duquesne Family Office, the personal investment firm of Stanley Druckenmiller, also disclosed a new position in Sandisk valued at $24 million as well as a $161 million position in Broadcom. Soros Fund Management, the namesake firm of George Soros, raised its Nvidia position by 61%, to $187 million, making it one of the family office's top 10 holdings. Some of these moves were fortuitous, with semiconductor stocks skyrocketing in recent months. Over the past 30 days, shares of Sandisk and Micron have both risen about 50% and 60%, respectively.
Shares of Nvidia, Broadcom and Taiwan Semiconductor gained by smaller percentages in recent weeks but have made substantial gains since last quarter. Broadcom and Taiwan Semiconductor are up about 35% and 19%, respectively, since the end of March, while Nvidia shares have risen by about 28%.
