What it reported after the quarter end (Q2 2026)
The 13F shows the portfolio as of Jun 30, 2026. Since then Duquesne Family Office has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.

Declared options (9)
Besides stocks, Duquesne Family Office declared 9 calls (they gain if it rises) with a notional of $857M. The 13F reports the value of the underlying shares, not the premium paid, so these figures look large and are not added to the portfolio. Nor does it say whether the option is bought or written, or its strike or expiry: it may be a hedge.

How we classify it
Family office, per its 13F and its Form ADV (medium confidence).
The data, as reported: Se declara «family office» en su 13F y no figura en el Form ADV (las oficinas familiares no se registran como asesores)
The type comes from a rule applied to that data. If it looks wrong, tell us.
Managers of a similar size
A 13F portfolio value between a third and three times this one, whatever the type of filer. It is not a comparison of what they hold.
