Stanley Druckenmiller

Family office

Runs Duquesne Family Office. Made his name on macro: the Quantum Fund years with Soros, then three decades of his own.

Stanley Druckenmiller runs Duquesne Family Office LLC, a focused book of 86 stocks worth $4.4B as of Q2 2026 (disclosed Aug 14, 2026, a ~45-day 13F lag). This quarter they opened Alphabet Inc-CL A and trimmed Ypf S.A.-Sponsored ADR. Their largest long position is Natera Inc at 20% of the equity book. They also disclosed $856.6M in call options (bullish), shown separately below and excluded from the equity book.

How to read this book

Duquesne's 13F is the equity shadow of a macro mind. The filing shows US-listed longs only, while Druckenmiller's real positions have always spanned bonds, currencies, and commodities you'll never find here.

What to watch: new tech names, because he concentrates when a thesis grips him. And sudden exits, because he changes his mind faster than almost anyone, and says so.

What's missing: everything that makes him Druckenmiller. The rates, FX, and short book. Same 45-day lag, and on a book that pivots quarterly, the lag bites hardest.

13F filers disclose option positions at the market value of the underlying the contracts reference, not the premium paid. A put is a bearish bet (it gains if the stock falls); a call is bullish. “Underlying shares” is the share count the contracts control, not a share holding. These legs are excluded from the equity book, weighting, concentration and sector figures above.
