Aschenbrenner's AI Fund Sells Public Portfolio to Citadel After Assets Plunge

Situational Awareness, founded by 25-year-old former OpenAI researcher Leopold Aschenbrenner with no trading background, sold most of its public stock portfolio to Citadel on July 30, 2026. The fund's assets fell from a $45 billion peak to about $10 billion, worsened by leverage. Hard-hit holdings included SK Hynix, SanDisk, Bloom Energy, and Nebius Group. The fund kept its private Anthropic shares.
