Ashenbrenner's Fund Lost Most of Its Stock Portfolio

Former OpenAI researcher Leopold Aschenbrenner's hedge fund, Situational Awareness, was forced to sell the majority of its public stock portfolio on July 30 after sustaining heavy losses. The portfolio, estimated at up to $16 billion, was purchased at a discount by Citadel, Ken Griffin’s firm. The rapid sale was triggered by a dual market shock: a sharp decline in the fund's concentrated bets on AI infrastructure stocks (like Nebius Group, Sandisk, Micron, CoreWeave) and losses from short positions on software firms like Adobe. The fund had used significant leverage, and falling share prices prompted margin calls from prime brokers including Bank of America, Goldman Sachs, and JPMorgan Chase. This came just weeks after the fund reported staggering gains of 439% for the first half of the year. Following the sale, the fund retains approximately $10 billion in assets, including a stake in AI company Anthropic, which was reportedly not part of the Citadel deal. Notably, major bitcoin mining stocks held by the fund—including IREN, Bitdeer, and Riot Platforms—surged 18-30% on the day of the sale.

Citadel buys bulk of Situational Awareness stock portfolio after AI rout: Reports

Citadel, founded by Ken Griffin, purchased a significant portion of the public stock portfolio from hedge fund Situational Awareness, founded by former OpenAI researcher Leopold Aschenbrenner. The deal followed heavy losses for Situational in July's AI stock market downturn, with reports indicating the fund fell approximately 67% that month, though it remained up about 80% for the year. Situational reportedly needed capital to meet margin calls and initially agreed to sell $3.5 billion of Anthropic shares before withdrawing from that deal. The fund's holdings, which included stocks like Sandisk, CoreWeave, and Bloom Energy that saw steep July declines, as well as positions in several Bitcoin mining companies, suffered during the rout. The specific stocks involved in the Citadel transaction are unclear. Situational Awareness is named after Aschenbrenner's essay series predicting artificial general intelligence by 2027.

$35 Billion Loss: OpenAI Star Leopold Aschenbrenner Sells His Trading Portfolio

Hedge fund Situational Awareness LP, founded by former OpenAI employee Leopold Aschenbrenner, sold off its entire portfolio of public stocks—both long and short positions—in a single block trade to Ken Griffin's Citadel in late July 2026. This reduced the fund's assets from a peak of roughly $45 billion earlier that month to about $10 billion. The forced sale was triggered by significant losses from a steep drop in AI infrastructure stocks like SK Hynix and adverse moves in short positions on software names such as Adobe. Prime brokers Bank of America, Goldman Sachs, and JPMorgan Chase issued margin calls, compelling the liquidation. Launched after Aschenbrenner's 2024 departure from OpenAI, the fund had previously reported stellar returns, including a 439% net gain for H1 2026. Its major public holdings, which included Nebius Group, Sandisk, Micron, and CoreWeave, all fell over 30-35% in July 2026. The fund will continue operating with its private investments, notably a stake in Anthropic valued at approximately $5 billion. The incident highlights the risks of concentrated leverage in the AI sector and draws parallels to the 2021 collapse of Archegos Capital Management, underscoring systemic vulnerabilities when multiple prime brokers face simultaneous margin calls.

The 25-Year-Old OpenAI Prodigy Who Took Global Investors Down With Him

At 25, OpenAI prodigy Leopold Aschenbrenner saw his $45 billion hedge fund, Situational Awareness, collapse in a month. His fund, which soared 439% by heavily leveraging AI infrastructure stocks like SK Hynix and CoreWeave, was caught in a vicious margin call spiral triggered by a sharp sell-off in AI hardware stocks and a rebound in the software stocks he shorted. The forced liquidation, intensified by leveraged Korean retail investors' panic selling, led to Citadel acquiring $16 billion of his portfolio at a steep discount. Ironically, the AI stocks he was forced to sell surged immediately after his fund's collapse. The episode underscores a classic Wall Street lesson: being right on the long-term trend is futile without surviving short-term volatility, especially when using excessive leverage. Despite the debacle, Aschenbrenner retains a $5 billion stake in Anthropic, leaving a potential path for recovery.

The End of This Bull Market's 'Greatest Myth': 'AI Stock God' Leopold Crushed in Weeks, Citadel Takes Over $16 Billion in Stock Assets

The once-celebrated "AI stock god," 24-year-old Leopold Aschenbrenner, has seen his hedge fund's spectacular rise end in a dramatic collapse. His fund, Situational Awareness (SA), built a narrative around explosive AI infrastructure demand, raising $45 billion and achieving a 439% return in H1 2026 by heavily leveraging (4x) concentrated long positions in stocks like SK Hynix and CoreWeave, while shorting legacy software firms. In July 2026, a sharp reversal hit AI stocks, triggering massive losses in both long and short positions. Facing margin calls from banks, SA was forced to sell its entire $16 billion public market portfolio in a 36-hour fire sale. Citadel acquired the assets at a significant discount, one of Wall Street's largest emergency stock trades. SA's assets under management plummeted from a $45 billion peak to roughly $10 billion, retained entirely in private holdings like a stake in Anthropic. The episode underscores that being right on a macro trend does not guarantee survival, highlighting the critical risks of extreme concentration and high leverage without a sufficient buffer against market shifts.

Hedge fund with $1.1B in Bitcoin miner stocks seeks capital after AI sell-off: FT

Hedge fund Situational Awareness, founded by ex-OpenAI researcher Leopold Aschenbrenner, is seeking new capital after heavy losses from an AI stock sell-off in July. The fund, which reportedly managed around $20 billion in assets, saw gains of 439% through June, but leveraged bets led to significant losses when AI stocks fell. Aschenbrenner argued the sell-off created new investment opportunities. The fund holds major positions in Bitcoin miners pivoting to AI, with a March SEC filing showing about $1.11 billion across stocks like IREN, Core Scientific, Riot Platforms, and CleanSpark. The fund was launched alongside Aschenbrenner's essays predicting artificial general intelligence surpassing college graduates by 2030.

Global Stock Market's Storm Center: South Korea's Stock Market De-leveraging Is Largely Complete

Storm's Eye: South Korean Market De-leveraging Nears Completion The recent sharp correction in South Korean equities, with the KOSPI index dropping 32% from its June high, has been a key trigger for global tech stock volatility. The core driver was not a fundamental shift but a forced de-leveraging process within the market's unique structure, which is now largely complete. Two main leverage channels amplified the sell-off: 1. **Leveraged ETFs:** Their size, proportionally four times larger than in the U.S., peaked near $50 billion. Their mandatory daily rebalancing mechanism created a vicious cycle of "price drop → forced selling → further drop." Approximately 75% of this excess has been unwound, shrinking to $26 billion, with regulatory curbs now blocking new inflows. 2. **Hedge Fund Leverage:** Using swaps to magnify exposure, hedge funds saw their net long positioning fall by over 50% from peak levels. The most intense phase of this institutional de-leveraging is over. In contrast, **retail margin debt** poses minimal systemic risk. At 0.5% of market cap, it is far lower than in the U.S. or China, lacks automatic triggers, and is concentrated in smaller stocks. The conclusion: the high-leverage structures most prone to "chain-reaction selling" have been substantially cleared. The market is transitioning from a liquidity-driven crash to one priced more on fundamentals. The article argues that the AI trend—centered on Korean memory chips—remains intact. This episode represents a painful but necessary clearing of crowded trades, not the end of the AI revolution. For investors, the key question is conviction in the long-term AI direction; if the trend is real, current volatility is a cost of entry, not a terminal risk.

Numerai Completes Third Strategic NMR Buyback, Bringing Total Repurchases to $3.2 Million

Numerai, a decentralized hedge fund powered by crowdsourced machine learning, has completed its third strategic open-market purchase of its NMR token, acquiring an additional $1.2 million worth. This brings the total NMR buybacks to $3.2 million within one year. The buybacks replenish the treasury used to reward contributors who stake NMR on their predictive models, aligning incentives with performance to improve the fund's core Stake-Weighted Meta Model. Since the first buyback in July 2025, Numerai's network has grown significantly, with active accounts more than doubling and new infrastructure like Numerai Skills and Atomic Blockchain Staking being introduced. The underlying hedge fund's assets under management have also increased to approximately $700 million from about $560 million at the end of 2025. The NMR token has a fixed supply of 11 million, with approximately 3.1 million remaining in Numerai's treasury prior to this latest purchase. This buyback was executed on the open market through Coinbase Institutional over several weeks to minimize market impact.

Strategy's Bitcoin Sales Cap Far Exceeds $1.25 Billion: A Detail the Market Overlooked

The article discusses how MicroStrategy's potential Bitcoin sales go far beyond the announced $1.25 billion "reserve-building capacity." It clarifies a key distinction in the company's "BTC Monetization Program": selling Bitcoin to *build* a new dollar reserve (the $1.25B cap) versus selling to *replenish* the existing USD Reserve after it's used for expenses like preferred share dividends. The recent $216M BTC sale for dividend payments was a "replenishment," leaving the headline $1.25B building quota untouched. The plan actually outlines three potential funding pools from BTC sales: 1) Building the reserve ($1.25B cap), 2) Covering preferred share/ debt costs (no specified cap), and 3) Funding buyback programs (up to $20B). This means the structured sales potential exceeds $30 billion, not including uncapped replenishment sales. The piece argues this marks MicroStrategy's shift from a passive "buy-and-hold" Bitcoin proxy to an actively managed entity using BTC as a balance-sheet tool to manage its complex capital structure (common stock, preferred shares, debt, reserve). This creates new dynamics and potential conflicts, as actions benefiting one part (e.g., selling BTC to pay dividends) may pressure another (e.g., undermining the "never sell" narrative). Investors must now parse the company's specific terminology ("build" vs. "replenish") to understand the true scope of future BTC sales, which is significantly larger than the market initially perceived.

Buffett and VC, One Must Lose

The article examines the perceived investment conflict between Warren Buffett's value-oriented approach and the current aggressive, tech-focused venture capital (VC) landscape, particularly in AI. It notes that while direct public debate is limited, underlying tensions exist as Buffett's Berkshire Hathaway holds record cash, signaling caution, while VCs pour unprecedented capital into tech. The piece revisits two historical confrontations: the 2000 dot-com bubble, where Buffett warned against speculative tech investments despite market euphoria, and his 2007-2017 bet against hedge funds, which he won by advocating low-cost index funds. In both cases, Buffett opposed investing based on hype, excessive fees, or complexity rather than concrete business value. The core argument is that Buffett does not oppose innovation or VC itself but critiques investment decisions detached from fundamentals—such as ignoring profitability, over-relying on narratives like “this time is different,” or obscuring valuation with complex structures. For the current AI boom, he would likely question sustainable business models and cash flows amid high capital costs. The conclusion reiterates Buffett's “Mr. Market” parable: investors should use market volatility to their advantage, not be guided by it, emphasizing that disciplined valuation, not sentiment, should drive decisions.
