The fund sold all of its long and short public stock positions to a single buyer. Situational Awareness, which managed roughly $20-24 billion in assets and had returned approximately 439% after fees in the first half of 2026, ran leverage as high as 4x on concentrated bets across the AI infrastructure stack — from power generation to data centers to memory chips 2 . When the July rout hit AI names broadly, Goldman Sachs, JPMorgan Chase, and Bank of America issued margin calls that forced the unwind . 1 https://www.cnbc.com/2026/07/30/leopold-aschenbrenners-hedge-fund-is-facing-steep-ai-losses.html The fund now retains only its private equity holdings, including a stake in Anthropic, and is actively seeking fresh capital from existing investors and lenders. Aschenbrenner has also offered some investors the opportunity to purchase portfolio assets directly 2 . The Unwind Situational Awareness's Q1 2026 13F filing showed roughly $13.68 billion in total notional exposure, including approximately $8.46 billion in put options, spanning the full AI infrastructure stack — power, compute, storage, and data center operators 3 . The fund's long book included Bloom Energy, CoreWeave, Nebius, Lumentum, Coherent, T1 Energy, Bitdeer Technologies, and HIVE Digital Technologies . 3 https://startupfortune.com/leopold-aschenbrenners-situational-awareness-fund-seeks-fresh-capital-after-ai-selloff-hammers-its-bets/ When the broader July AI selloff accelerated, all of those positions came under severe pressure simultaneously. An unofficial tracking account on X estimated the portfolio dropped roughly $600 million in a single session on July 28 2 . Short positions in software companies such as Adobe moved sharply against the fund at the same time, compounding losses . 1 https://www.cnbc.com/2026/07/30/leopold-aschenbrenners-hedge-fund-is-facing-steep-ai-losses.html The disclosure of Aschenbrenner's exit from Lumentum and Coherent — both optical networking companies that supply AI data centers — sent those stocks lower by 11% and 6%, respectively 5 . From 439% to Forced Seller Founded in mid-2024 by the former OpenAI researcher after his dismissal from the company, Situational Awareness operated on the thesis that artificial general intelligence development would reshape global markets and that AI infrastructure companies would be the primary beneficiaries 2 . The fund's extraordinary first-half performance made Aschenbrenner one of the most closely watched investors in the AI trade. But the same leverage and concentration that produced those returns left the fund acutely vulnerable to a reversal. With positions spread across the entire AI infrastructure supply chain and leverage reportedly as high as 4x, even a moderate correction in AI names created outsized margin pressure 1 . Goldman Sachs and JPMorgan Chase were among the prime brokers that issued margin calls to funds with highly leveraged AI portfolios during the July selloff, a move that affected multiple funds beyond Situational Awareness 2 . Raising Fresh Capital In a July 24 letter to investors — six days before the full liquidation became public — Aschenbrenner framed the drawdown as a buying opportunity and invited new capital commitments starting August 1 4 . He cited a potential Anthropic IPO as a key catalyst for sector recovery . 2 https://finance.yahoo.com/technology/ai/articles/ai-wizkid-leopold-aschenbrenner-seeks-113210756.html The fund has approached existing investors and lenders for new money and has been marketing stakes in privately held companies, including its Anthropic position, to raise liquidity 2 . Some investors were offered the chance to buy portfolio assets directly . 2 https://finance.yahoo.com/technology/ai/articles/ai-wizkid-leopold-aschenbrenner-seeks-113210756.html Whether Aschenbrenner can reload and re-enter the trade depends on investor appetite after a whipsaw that turned one of the year's best-performing funds into a forced seller in a matter of weeks. Market Fallout The forced liquidation adds to a growing list of AI-concentrated funds that have faced margin pressure during the July selloff. The episode underscores the risks of leveraged, concentrated bets in a sector that had seen relentless gains through the first half of 2026. Shares of several companies in Situational Awareness's known portfolio remained under pressure on July 30. Bloom Energy, CoreWeave, and Nebius — all identified as long positions in the fund's 13F — have declined sharply from their June highs 3 . Lumentum and Coherent fell further after news of the fund's exit . 5 https://sherwood.news/markets/lumentum-coherent-fall-after-hedge-fund-manager-aschenbrenner-dumps-his-holdings/ Companies mentioned Further sources 1 CNBC - Leopold Aschenbrenner's hedge fund is facing steep AI losses ↗ https://www.cnbc.com/2026/07/30/leopold-aschenbrenners-hedge-fund-is-facing-steep-ai-losses.html 2 Yahoo Finance / Investing.com - AI wizkid Leopold Aschenbrenner seeks new funds… ↗ https://finance.yahoo.com/technology/ai/articles/ai-wizkid-leopold-aschenbrenner-seeks-113210756.html 3 Startup Fortune - Leopold Aschenbrenner's Situational Awareness fund seeks fres… ↗ https://startupfortune.com/leopold-aschenbrenners-situational-awareness-fund-seeks-fresh-capital-after-ai-selloff-hammers-its-bets/ 4 The M&A Hunter / Substack - Situational Awareness sold entire public equity boo… ↗ https://substack.com/@maandhunter/note/c-304758666 5 Sherwood News - Lumentum, Coherent fall after hedge fund manager Aschenbrenner … ↗ https://sherwood.news/markets/lumentum-coherent-fall-after-hedge-fund-manager-aschenbrenner-dumps-his-holdings/ The stories that matter, in one email.
