# Citadel buys Situational Awareness's entire public-equities portfolio after AI losses

_Thursday, July 30, 2026 at 12:18 PM EDT · Capital, AI · Breaking · Tier 1 — Major_

Situational Awareness, the AI-focused hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, sold its entire public-equities portfolio to Ken Griffin's Citadel, Axios reported Thursday, citing a source. The firm recently reported about $20 billion in assets under management.

The sale followed a recent sell-off in AI stocks, especially chipmakers. The Wall Street Journal first reported the transaction. The Financial Times reported a day earlier that Situational Awareness was seeking fresh capital after suffering heavy losses during the AI-stock rout.

Aschenbrenner founded Situational Awareness after leaving OpenAI in 2024. Early investors included Stripe co-founders Patrick and John Collison, former GitHub chief executive Nat Friedman and former Apple employee Daniel Gross.
