Ken Griffin's Citadel posts best month in years after scooping up Situational Awareness stocks

Key Points:

• Ken Griffin's Citadel reported strong gains across its major hedge funds in July, driven by a market recovery and a discounted acquisition of assets from the collapse of Leopold Aschenbrenner's Situational Awareness fund.
• Citadel's flagship multistrategy Wellington fund returned 5.9% in July, its best monthly performance since 2022, bringing 2026 gains to 12%, while the tactical trading and equities funds posted their best months ever with returns of 11.1% and 14.2%, respectively.
• The gains followed Citadel's purchase of the majority of Situational Awareness's public-stock portfolio at significant discounts after the fund faced steep losses and forced asset sales due to margin calls.
• Situational Awareness, founded by former OpenAI researcher Leopold Aschenbrenner, was forced to unwind positions after an unsuccessful AI trade strategy, which involved heavy bets on AI infrastructure and short positions on software stocks.
• Citadel, managing about $71 billion in assets, capitalized on the forced liquidation, acquiring key holdings and benefiting as stocks like Nebius and Micron rebounded, with the event seen as a market clearing that prompted short sellers to take profits.
