Bloomberg reports AI-powered voice phishing targeted major hedge funds, including Citadel and Two Sigma, with attackers using AI-generated voices to bypass security; Two Sigma says it detected the attack in time, while other firms did not immediately respond to comment, highlighting the growing risk of AI-enabled impersonation and the need for stronger safeguards in AI systems.
Citadel’s Wellington multistrategy fund rose 5.9% in July—the best month since 2022—lifting 2026 gains to about 12% as the firm benefited from a market rebound and acquired much of the former Situational Awareness public stock portfolio at a discount after its collapse; its tactical fund jumped 11.1% in July (up 27% YTD) and the equities fund gained 14.2% (up 27% YTD), with both posting their best months ever, while Citadel managed about $71 billion in assets as of July 1 and declined to comment.
Citadel’s Wellington fund rose about 5.9% in July after purchasing billions of AI-related stocks from Leopold Aschenbrenner’s troubled Situational Awareness in a rapid, less-than-24-hour sale, at roughly a 10% discount. The deal leaves Wellington up about 12% this year as AI equities wobble, and analysts say the purchase helped stem a broader AI-stock selloff while boosting some of Aschenbrenner’s former holdings like Bloom Energy and SanDisk.
Twenty-four-year-old Leopold Aschenbrenner, founder of the AI-focused hedge fund Situational Awareness, watched his $45 billion portfolio unravel after aggressive AI bets, including a large private stake in Anthropic; he reportedly sold billions of holdings to Citadel’s Ken Griffin to stem losses, yet the firm still oversees more than $10 billion. A former FTX/OpenAI associate turned crypto-fast celebrity, Aschenbrenner has attracted major investors and media attention as he prepares for a Carmel-by-the-Sea wedding with Avital Balwit, while vowing better risk management going forward.
Leopold Aschenbrenner’s AI-focused hedge fund Situational Awareness suffered a 67% drawdown in July as AI stocks slumped. To protect investors, the fund sold part of its public book, removed leverage, and now runs a fully paid-for public portfolio while keeping private positions. The fund, which had swelled to about $45B before the drop, is still up roughly 80% for the year and remains invested in Anthropic. Aschenbrenner promises to learn from the episode, implement risk and portfolio-management changes, and is available for 1:1 investor calls next week.
When rivals faced catastrophic AI-stock losses, Citadel founder Ken Griffin stepped in to salvage California hedge fund Situational Awareness after its July portfolio fell 67% and the firm unwound most of its $16 billion public-equities book. Griffin and his team reviewed positions overnight and ended up purchasing a chunk of the book, continuing Citadel’s pattern of stepping in during market stress.
Leopold Aschenbrenner’s AI-focused hedge fund Situational Awareness collapsed after margin calls forced a distressed sale of its public holdings to Ken Griffin’s Citadel, wiping out roughly $35 billion from a peak near $45 billion. Prime brokers Bank of America, Goldman Sachs, and JPMorgan Chase helped meet margin requirements as the fund’s leveraged positions were dumped, with as much as 400% leverage cited. The portfolio included AI infrastructure bets and private stakes like Anthropic, Nebius Group, Sandisk, Micron, and CoreWeave; the fund had posted outsized gains since its 2024 inception but investors warned of trouble, and the crash occurred as founder Leopold Aschenbrenner, 25, was preparing to marry Avital Balwit.
Leopold Aschenbrenner, a former OpenAI researcher who launched the AI-themed hedge fund Situational Awareness, saw its assets peak at about $45 billion before a market downturn forced a liquidation of levered bets—selling public AI names like SK Hynix and CoreWeave to Citadel at a discount and shrinking holdings to roughly $10 billion. The piece traces his meteoric rise, controversial background (FTX ties, OpenAI security memo, and Effective Altruism), and the volatility of AI-driven investing.
Leopold Aschenbrenner, once hailed as the AI era’s golden boy behind the $20bn Situational Awareness hedge fund, posted extraordinary early gains on debt-fueled bets on AI, but a sharp AI-stock rout and lender pressure led to a rapid unwind and a late-night deal selling much of the portfolio to Citadel’s Ken Griffin. His background—from OpenAI/Anthropic links to a self-published AI treatise—highlights questions about risk, infrastructure, and how a young trader built such a fortune.
Leopold Aschenbrenner’s AI-driven bet for his hedge fund Situational Awareness turned costly as AI stocks plunged and leverage forced unwinds; Citadel bought much of the fund’s public stock holdings while private AI bets were retained, illustrating a perennial Wall Street lesson: a strong investment thesis can be overwhelmed by market timing and margin calls, as echoed by LTCM and Clarium.
