What a 13F shows

This is Situational Awareness’s Form 13F for the quarter ended Jun 30, 2026, filed with the SEC on Aug 14, 2026 as Situational Awareness LP. A 13F lists long positions in US-listed securities on the quarter’s last day: shares, convertible bonds, puts and calls. It does not list short positions, cash, private holdings or most securities listed abroad, and a position may have changed since.

Options are shown as options, never added to the shares of the stock they are written on. A change is the share count against the fund's filing for Q1 2026; the estimated value of a change uses the price the filing's own figures imply. Where a count moved with a stock split, no change is shown.
