About Stanley Druckenmiller

Stanley Druckenmiller built his reputation running money for George Soros at Quantum Fund, where he architected the 1992 short of the British pound — a trade that netted roughly $1 billion in a single day and remains the canonical example of macro discretionary conviction sized to maximum effect. He later ran Duquesne Capital Management until closing it to outside capital in 2010, citing the difficulty of sustaining returns at scale; the vehicle is now the Duquesne Family Office. His edge has always been macro — currencies, rates, equities, and commodities woven together — meaning the 13F captures only the long U.S. equity sleeve and systematically omits the futures, options, and FX positions that have historically driven his returns. The current book is concentrated by most standards (top-5 at ~43% of disclosed equity exposure), with NTRA the dominant position, but readers should weight the filing accordingly: what's visible here is probably not where the real risk lives.

2026Q2 brief

2026Q2 activity: 44 new positions (top: GOOGL, FOXA, CDW); 11 conviction adds (top: INSM, AMZN, Seagate Tech); 23 exits (top: AVGO, OPCH, FIGR). Top 5 holdings: NTRA, TSM, STM, INSM, YPF (38% of portfolio).
