Duquesne Family Office LLC
Stanley Druckenmiller · New York, NY · Founded 2010
The Duquesne Family Office invests the capital of Stanley Druckenmiller, one of the most renowned macro investors of the modern era. Druckenmiller ran Duquesne Capital from 1981 to 2010 with famously consistent returns and no losing year, and helped run George Soros's Quantum Fund — including the 1992 bet against the British pound.
He closed Duquesne to outside money in 2010 and now invests through the family office, blending top-down macro views with concentrated equity positions, notably in technology and AI beneficiaries. The 13F shows the US-listed equity slice of that book.
How to read these tables. A Form 13F reports each holding's market value as of the quarter-end date and the share count — not the price the fund paid, when it bought, or any short positions. Buys and sells are inferred by comparing share counts across quarters. Put/call lines are options (often hedges), and their value is notional rather than a straight equity stake. Figures are the fund's US-listed 13(f) holdings only; private positions appear when the manager reports them.
