Summary
Leopold Aschenbrenner's artificial intelligence-focused hedge fund, Situational Awareness, experienced a catastrophic 67% portfolio decline in July 2026, marking one of the most significant monthly drawdowns in hedge fund performance. The losses stemmed from concentrated, leveraged long positions in AI stocks that deteriorated sharply during the month. The fund's collapse occurred despite maintaining a strong year-to-date return of approximately 80% through July, underscoring the reversal in AI sector sentiment and the risks inherent in concentrated directional bets during volatile market conditions.
Aschenbrenner, a former executive at both OpenAI and FTX, established Situational Awareness with $225 million in committed capital, positioning it as a specialized vehicle for navigating artificial intelligence investment opportunities. The fund's dramatic July performance decline triggered intervention from Citadel, Ken Griffin's flagship hedge fund, which acquired a substantial portion of Situational Awareness' public equity positions. This stabilizing transaction preserved the fund's asset base, which remained in the vicinity of $10 billion following the month's losses, preventing further forced liquidations.
Despite the severe drawdown, Aschenbrenner communicated to investors that the fund would "fight another day," signaling operational continuity and a commitment to remaining engaged in AI market opportunities. The July 2026 losses serve as a cautionary case study for institutional investors regarding concentration risk, leverage amplification, and sector-specific volatility in artificial intelligence equities during periods of rapid market repricing.
