Duquesne Family Office 13F: Q2 2026 Portfolio — $5.21B Across 95 Positions

Duquesne Family Office’s Q2 2026 activity shows a clear tilt toward high-conviction semiconductor exposure: the largest position, Natera, was increased to a 16.6% weight on the quarter, while Taiwan Semiconductor Manufac rose to a 5.4% weight with share count up 19.1%, and Stmicroelectronics N V moved up to a 4.46% weight with share count up 18.8%. These additions reinforce a concentrated top-10 structure, with total top-10 weight at 45.8% alongside 17 adds and only 10 trims.

Alongside the semiconductor theme, the quarter also brought in several new positions (48 new) and selective reduction elsewhere. Amazon was added with an extreme share count increase of 1082.5% to a 2.48% weight, while Insmed was added to 2.92% with shares up 23.4% and a separate Insmed (CALL) option-style line entered as a new holding at a 2.76% weight. Offsetting this, the firm trimmed Ypf Sociedad Anonima by 3.0% share count to a 2.74% weight and reduced Bbb Foods by 6.7% to a 2.32% weight.

The exit list underscores a broader cleanup: 23 positions were fully exited, including Broadcom, Option Care Health, and Figure Technology Solutio, among others. At the same time, several holdings were held steady (20 holds), such as the two listed S&P 500 equal-weight ETF call/holding lines, suggesting the rotation was focused on rebalancing rather than wholesale de-risking.

A Form 13F is a quarterly snapshot institutional managers with over $100M in US-listed assets must file within 45 days of quarter end. It shows long equity positions only: no short book, no cash, no non-US listings, no timing inside the quarter. Treat it as a delayed map of where the manager's conviction sat on the reporting date — not a live portfolio, and not a buy list.
