   Situational Awareness Returns to AI Options After $35 Billion Loss

   Leopold Aschenbrenner is resuming AI trades via the options market following a summer collapse that erased roughly $35 billion in assets. The fund suffered a 67% drawdown and conducted a $16 billion fire sale of assets after a brutal reversal in July. While Citadel previously stepped in to salvage the portfolio and remove 80% of its risk, the Bank for International Settlements now cites the fund's failure as evidence of systemic risks posed by leveraged hedge funds globally.

   Why it matters

   The fund previously reached a peak value of $45 billion before a chip stock selloff triggered the crash. The SEC is currently investigating the near-collapse. This event highlights the volatility of concentrated AI bets by high-leverage managers.

   What is confirmed

   • Situational Awareness lost roughly $35 billion in assets after a forced sale this summer.
   • Leopold Aschenbrenner is returning to the AI trade after a July reversal.
   • The fund is active in options markets as of late last week and early this week.

   Still unconfirmed

   • The fund experienced a 67% drawdown and a $16 billion fire sale.
   • The Bank for International Settlements warns that the fund's collapse exposes systemic risks from leveraged hedge funds.

   What to watch next

   • SEC findings regarding the fund's collapse
   • Further asset acquisitions or risk reductions by Citadel
   • Performance of the fund's new AMD options bets

   SEC investigates Situational Awareness as Citadel cuts portfolio risk

   The Securities and Exchange Commission is investigating the near-collapse of Situational Awareness, the AI-focused hedge fund managed by 24-year-old Leopold Aschenbrenner. The probe follows a chip stock selloff that forced the fund into asset sales. Meanwhile, Ken Griffin stated in a letter that Citadel has removed 80% of the risk from the Situational Awareness portfolio it acquired to salvage assets. This follows a period where the fund lost a significant portion of its peak $45 billion value.

   Why it matters

   Situational Awareness specialized in artificial intelligence investments but lacked diversification. The fund's instability led to a $20 billion stock sale by Aschenbrenner to ensure survival before Citadel stepped in.

   What is confirmed

   • The SEC is investigating the near-collapse of the AI-focused hedge fund Situational Awareness.
   • Ken Griffin stated Citadel has shed 80% of the risk from the Situational Awareness portfolio.

   What to watch next

   • SEC findings regarding the cause of the fund's collapse
   • Further asset liquidation or restructuring by Citadel

   Situational Awareness AI Fund Collapses After Massive Portfolio Drop

   Leopold Aschenbrenner's AI-focused hedge fund, Situational Awareness, imploded in late July 2026 after a rapid market decline. The fund reached a peak of $45 billion in assets before losing a significant portion of its value over several weeks. Aschenbrenner, a former OpenAI researcher, sold $20 billion in stock this week to maintain survival. While the fund suffered from a lack of diversification and prudence, some market professionals believe the 24-year-old investor can still stage a financial comeback. Citadel acquired the portfolio to salvage remaining assets.

   Why it matters

   Launched in 2024 with $100 million, the fund became a symbol of AI-driven analytical power in finance. Its collapse serves as a warning about the high risks associated with concentrated AI investments. The event highlights the tension between aggressive AI growth strategies and traditional investment prudence.

   What is confirmed

   • Leopold Aschenbrenner is a former OpenAI researcher.
   • Situational Awareness reached $45 billion in assets at its peak.
   • The fund was launched in 2024.

   Still unconfirmed

   • Aschenbrenner sold $20 billion in stock this week to survive.

   What to watch next

   • Evidence of Aschenbrenner launching a new investment vehicle.

   Situational Awareness hedge fund implodes, sold to Citadel

   The $45 billion AI hedge fund Situational Awareness, led by 24-year-old Leopold Aschenbrenner, suffered massive losses and was largely sold to rival Citadel. The fund's portfolio plummeted, with some reports indicating a 67% dip. Aschenbrenner, dubbed the "Nostradamus of AI", faced intense scrutiny over his investment strategies. Citadel's acquisition of the portfolio aims to salvage the situation.

   Why it matters

   The collapse of Situational Awareness has significant implications for the AI investment landscape and raises questions about the risks associated with giving young, inexperienced investors large sums of money to bet on complex technologies. The incident may also impact the broader hedge fund industry, particularly those focused on AI investments. The sale to Citadel, a well-established player, could help mitigate some of the damage.

   What is confirmed

   • Situational Awareness' portfolio plummeted by 67%, according to the New York Post.
   • Citadel acquired most of Situational Awareness' stock holdings after the AI share rout, sources say.
   • Leopold Aschenbrenner, 24, was the founder of Situational Awareness.
   • The fund's collapse has raised questions about the risks of AI investments and the experience of young investors.

   Still unconfirmed

   • Aschenbrenner's letter to investors apologized for the fund's performance, saying "We let you down this month".

   • The impact of Situational Awareness' collapse on the broader AI investment landscape
   • Citadel's plans for the acquired portfolio
   • Potential regulatory changes or increased scrutiny of AI-focused hedge funds
