Duquesne Family Office LLC

Background

Duquesne Family Office LLC is the personal investment vehicle of Stanley Druckenmiller, who ran Duquesne Capital Management from 1981 until closing it to outside investors in 2010, citing the difficulty of maintaining returns at scale. During those decades he also served as lead portfolio manager under George Soros, executing the trade that broke the Bank of England in 1992.

The family office structure means he manages his own capital with no redemption pressure, which historically shapes a portfolio willing to hold concentrated, sometimes unconventional positions.
