Ken Griffin's Citadel capitalized on a significant opportunity in late July when it acquired a heavily discounted stock portfolio from Situational Awareness, an AI-focused hedge fund that collapsed amid steep losses. This strategic purchase helped Citadel's main funds achieve strong returns, with the equities fund jumping 14.2% last month.
Citadel's Impressive July Performance
In July, Citadel's flagship multistrategy Wellington fund returned 5.9%, marking the best monthly performance since early 2022. Meanwhile, the tactical trading fund, which blends discretionary equity strategies with algorithm-driven approaches, climbed 11.1% in the same period, lifting its 2026 gains to 27%. Additionally, the equities fund saw a 14.2% increase in July, pushing its 2026 returns to 27%. Both the tactical and equities funds recorded their best months on record. Citadel reported managing around $71 billion in assets as of July 1, leveraging market turbulence to invest in distressed or forced-selling scenarios.
The Collapse of Situational Awareness
Situational Awareness, led by former OpenAI researcher Leopold Aschenbrenner, suffered significant losses due to its AI-focused trading approach. The fund had built large stakes in companies providing AI hardware while simultaneously betting against software stocks. When the market unexpectedly reversed, software shares surged and hardware companies tumbled, causing the fund to bleed on both sides of its positions.
The losses triggered margin calls and forced the firm to sell assets, which eventually led to its collapse. As the fund struggled to meet its obligations, several prime brokers assisted in reducing positions in a controlled manner. Citadel emerged as the main buyer of the portfolio, profiting from one of the most significant forced liquidations of the year.
Key stocks, including Nebius and Micron, rebounded in the final days of July after suffering heavy losses. Industry observers believe that the collapse of Situational Awareness and Citadel's acquisition of its holdings acted as a clearing event that prompted short sellers to lock in gains. Citadel declined to make further comments about the transactions.
