Summary

This episode examines the rapid rise and sudden collapse of Leopold Aschenbrenner’s $45 billion hedge fund, Situational Awareness. Hailed as an AI investing prodigy, Aschenbrenner’s firm imploded days before his high-profile wedding due to over-leverage and a drop in SK Hynix stock. To survive margin calls, he sold most assets to Citadel at a discount, highlighting the risks of excessive debt in volatile markets.
