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

cointelegraphPublished on 2026-07-31Last updated on 2026-07-31

Abstract

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.

Ken Griffin’s Citadel reportedly bought a large proportion of the public stock portfolio of Situational Awareness, the hedge fund founded by former OpenAI researcher Leopold Aschenbrenner.

The Financial Times first reported Thursday that Citadel bought the discounted portfolio after heavy losses during July’s artificial intelligence stock market rout.

The transaction followed Aschenbrenner’s fund falling about 67% in July, according to The Wall Street Journal, citing a person who saw a letter sent to investors. The letter said the fund remained up about 80% for the year. The Financial Times previously reported the fund was up 439% through June.

Those reports suggested Situational had approached existing investors and lenders for fresh capital and offered some investors the option to buy portfolio assets. The Journal also reported Situational needed cash to meet margin calls from its lenders and that the fund agreed late Wednesday to sell $3.5 billion of Anthropic shares to a group led by Greenoaks and Sequoia Capital before withdrawing from the deal Thursday morning.

Reuters separately reported the leveraged-portfolio detail but said it could not determine whether formal margin calls had been issued before the sale. Reuters said Situational retained roughly $10 billion in stocks and private investments, including Anthropic.

AI holdings suffered steep July falls

Several stocks linked to the fund suffered sharp declines in July. Sandisk remained down about 44% for the month even after closing Thursday up 26%. CoreWeave fell nearly 26% in July, while Bloom Energy was down around 32%, Yahoo Finance data shows.

Situational’s US Securities and Exchange Commission filing showed direct share positions in all three companies as of March 31.

The same filing showed about $1.11 billion in shares of seven Bitcoin (BTC) mining companies, including Iren, Core Scientific, Riot Platforms and CleanSpark. Cointelegraph previously reported that the positions gave Situational exposure to miners expanding into AI and high-performance computing by repurposing their power supplies and data center sites.

It remains unclear what stocks were part of the transaction between Citadel and Situational or whether the fund retained any of its Bitcoin miner positions.

Aschenbrenner’s fund takes its name from his 2024 essay series, “Situational Awareness: The Decade Ahead,” which argued that artificial general intelligence could arrive by 2027 and drive enormous demand for computing power and electricity.

Before joining OpenAI, Aschenbrenner was a member of the FTX Future Fund’s five-person team and signed its November 2022 resignation notice as FTX collapsed.

Cointelegraph contacted Situational Awareness and Citadel for comment but had not received a response by publication.

In Conversation with Ray Dalio: We Are Currently in an AI Bubble, with 1% of My Portfolio in Bitcoin

Ray Dalio, founder of Bridgewater Associates, warns in an interview that the current AI boom shows classic bubble characteristics, which could lead to significant economic downturns as seen in past cycles like 1929 or 2000. He explains that speculative enthusiasm, fueled by debt and overvaluation, often precedes a crash when rising rates or taxation force asset sales, causing widespread losses and recession. Dalio also outlines his "Big Cycle" theory, describing an approximate 80-year pattern where widening wealth gaps, massive government deficits, and shifting geopolitical power (like China's rise) create internal conflict and global instability. He emphasizes that we are in a late-cycle, transitional phase where traditional powers like the US and UK face decline. For personal wealth protection, Dalio advises diversification beyond cash into assets like stocks, bonds, real estate, and particularly gold, which he prefers over Bitcoin. While he holds about 1% of his portfolio in Bitcoin as a non-printable hard asset, he views gold as more secure from technological or governmental threats. Regarding AI's impact, Dalio believes it will disproportionately benefit capital owners, worsening inequality by replacing both physical and cognitive labor. He suggests that human intuition and emotional intelligence, combined with AI, will be key for future workers. On taxation, Dalio argues that wealth taxes are impractical and risk triggering asset sell-offs, reducing productive investment. He points to the UK as a cautionary example of debt, low productivity, and political strife. Geopolitically, Dalio foresees a more regionalized world, with the US showing weakness in prolonged conflicts like with Iran, akin to past imperial declines. The ideal outcome, he suggests, is coexisting powerful blocs (e.g., Americas, China-Asia Pacific) without major war.

Daily 7.2 Trillion KRW: Foreign Capital's Record Net Buying on Friday! Wall Street Says Headwinds for Korean Stock Fund Flows Have Subsided

South Korean stock market sees a dramatic shift in fund flows. On July 31, foreign investors made a record net purchase of approximately KRW 7.2 trillion in KOSPI stocks, marking a fundamental reversal from the persistent large-scale net outflows seen in previous months. This contributed to a significant narrowing of foreign net selling in July to KRW 9.8 trillion, down sharply from KRW 48.4 trillion in June and KRW 44.5 trillion in May. Simultaneously, domestic institutional pressure eased. South Korean pension funds and asset managers turned to a net buying position in July, purchasing KRW 1.0 trillion worth of KOSPI shares, contrasting with net sales in May and June. Market volatility is expected to be dampened by new financial regulations. Effective July 31, the Financial Services Commission tightened access for retail investors to single-stock leveraged ETFs by raising the minimum cash deposit requirement. Trading volumes for these products subsequently dropped to about 50% of their monthly average. Citigroup Research maintains its year-end KOSPI target of 10,000 points. The firm cites several supportive factors: the substantial easing of headwinds from capital outflows, a robust fundamental outlook for the semiconductor sector, historically low market valuations, strong economic fundamentals, and the potential for policy support from financial authorities if needed.

Thanks to Dice Rolls, Bitcoin Keys Are Stored Offline, But Not Everyone Will Do It

The article discusses using dice rolls to generate secure Bitcoin wallet seeds, providing entropy independent of potentially flawed hardware random number generators. It explains that each fair dice roll offers about 2.585 bits of entropy, with around 50 rolls needed for a standard 12-word seed phrase and 99+ recommended for higher security. This method gained attention after a vulnerability was revealed in some Coldcard hardware wallets, where a faulty firmware RNG (dating back to 2021) compromised generated keys. The analysis notes that while a dice-generated main seed was safe from this specific flaw, other Coldcard functions (like creating paper wallets, backup keys, or passwords) could still be vulnerable if they used the defective RNG. The piece argues that while dice-based entropy is technically robust, the manual process is error-prone, tedious, and unrealistic for most new users, who might make mistakes in recording or inputting rolls. It concludes that while manual entropy generation should remain an option for advanced users, the long-term goal is to develop reliable, user-friendly hardware and software that securely generates randomness without requiring specialized knowledge. Coldcard users are advised to check their firmware version and replace any secondary secrets (like paper wallet keys) created with vulnerable devices, while also considering multi-signature setups with devices from different manufacturers for added security.
