Leopold Aschenbrenner's fund experienced a significant blow-up after achieving over 1,000% returns since its 2024 launch, fueled by concentrated leverage bets on AI stocks and private securities. When sentiment for AI names shifted, prime brokers issued margin calls, forcing the fund to liquidate a $45 billion portfolio to remain solvent.
“The latest example comes from Leopold Aschenbrenner's situational awareness. The fund returned more than 1,000% since its launch in 2024, including 439% in the first half of this year.”
