Situational Awareness LP (Leopold Aschenbrenner) files 13F on the long US-listed equity/ETF/options book only. Private stakes (e.g. lab/AI names) and cash are outside this sleeve. The latest 13F is quarter-end — later public-book sales do not rewrite that table.

Options & listed derivatives (3)

13F only reports long / purchased listed options (the manager bought the call or put). There is no field for written / sold / short options — those typically do not appear on 13F at all. Put vs Call is the contract type, not buy vs sell. Strike, expiration, and multiplier are also not disclosed. Share-equivalent is what the filing reports; est. contracts assume the usual 100-share unit. Value is the 13F reported value (not a live option mark).
