Founded Situational Awareness Works at Situational Awareness
Leopold Aschenbrenner is the founder and hedge fund manager behind Situational Awareness, an AI-focused investment vehicle concentrated in AI infrastructure and run with significant leverage. Recent coverage says the fund suffered steep losses after AI stock declines, triggering margin calls and liquidation/sale of most public holdings, with assets reportedly dropping from around $45 billion to about $10 billion. He has also been connected to an SEC inquiry after regulators subpoenaed banks linked to the fund, and Aschenbrenner has appeared in an epistemics-related discussion of how to evaluate claims and authority in reasoning.
