Billionaire family offices boosted chip and energy holdings in Q1 2026 filings

In the first quarter of 2026, several billionaire-linked family offices increased positions in semiconductor names and, in some cases, energy producers, even as the Iran war weighed on data-center economics and pushed oil prices higher. Stakes rose across firms including Appaloosa, Duquesne, and Soros Fund Management, with notable changes such as larger Micron and Nvidia holdings and new Sandisk exposure. Some offices also trimmed or exited select chip, power, and airline positions while locking in gains.
