On Aug 14, 2026, covering the quarter that ended Jun 30, 2026. The next one is due within 45 days of the next quarter end, so the positions here can be up to 45 days old on the day they are published.

Does this page show everything Duquesne Family Office owns?

No. A 13F covers long positions in US-listed stocks, certain options and convertible notes. It leaves out short positions, cash, bonds, private holdings and shares listed outside the US, so the total here is not the fund's full size.

Data from SEC EDGAR filings. 13Fs are quarterly and lag by up to 45 days, cover only US-listed long positions and certain options, and exclude shorts and non-US holdings. Not investment advice.
