Overview
- Situational Awareness nearly collapsed after steep losses in AI and semiconductor stocks reduced assets under management from roughly $45 billion to about $10 billion when lenders enforced margin calls.
- Leopold Aschenbrenner agreed to divest most of the fund’s public equity book to Ken Griffin’s Citadel, a rapid block purchase that removed the selling pressure and let the fund settle its lenders.
- The fund had used extremely high leverage, reported up to 400%, and concentrated on AI‑infrastructure positions which amplified losses and triggered the forced unwind.
- After the public unwind the manager doubled down on private investments, committing a newly confirmed $400 million to a Sequoia‑backed private company on top of a $100 million stake taken last month with that deal confirmed by Sequoia partner Alfred Lin.
- More than 5,000 retail investors still mirror Aschenbrenner’s disclosed public portfolio on platforms like Autopilot which do not use leverage, and the episode has sharpened scrutiny of prime‑broker margin practices and the risks of pairing heavy leverage with illiquid private bets.
