AI fund Situational Awareness pulls back Jane Street, losing $15 billion in July

Comparatively, Wall Street quantitative trading giant Jane Street lost about $15 billion in the July market sell-off due to investments in AI-themed hedge fund Situational Awareness and other tech stocks. People familiar with the matter revealed that despite a major pullback in July, Jane Street's transaction revenue has exceeded 40 billion US dollars since this year, far higher than the world's major banks and other market makers, and exceeds its trading revenue of 39.6 billion US dollars for the whole year of 2025. Jane Street confirmed in an internal memo to employees that July was a “bad month” for the company. The company said that the AI-themed hedge fund Situational Awareness, which it invests in, previously expanded its position due to strong performance in the first half of the year, but there was a sharp retracement during the sharp decline in AI stocks, causing the earnings of Jianjie-related investments to basically return to a flat level this year, but they are still more profitable than when they were initially invested. Situational Awareness was founded by Leopold Aschenbrenner, a former OpenAI researcher, and has received market attention due to heavy holdings in AI-related stocks. After the AI sector was drastically adjusted in July, the fund sold most of its stock positions to Citadel, a subsidiary of billionaire Ken Griffin, due to triggering margin requirements. Jane Street said the loss also came from long positions in Asian non-AI stocks, which had previously performed well earlier this year. According to the company, many large storage and semiconductor stocks fell by about 50% in July, causing its previously well-performing trading portfolio to retreat. (Reuters)

AI stock god Leopold's pre-thunderstorm positions revealed: SanDisk and Micron two stocks account for half

According to the latest disclosure documents from the US SEC, the Situational Awareness LP under AI stock god Leopold Aschenbrenner submitted 13F-HR on August 14, 2026, which revealed a snapshot of open positions prior to the July liquidation crisis. According to this 13F information sheet, Situational Awareness reports that the total declared value of positions is about US$20.04 billion. Among them, positions are highly concentrated: SanDisk is about US$5.674 billion, accounting for about 28.0%; Micron is about US$5.574 billion, accounting for about 27.5%. The total of these two storage chain labels alone is over $112 billion, accounting for about 55.5% of the combination. In addition to memory chips, the portfolio also re-invests in AI infrastructure and computing power chains: Bloom Energy approximately US$1,899 million, TSMC ADR approximately US$1.65 billion, Nebius approximately US$1.23 billion, CoreWeave approximately US$745 million, and Scientific Core approximately US$666 million. The document also shows that it holds targets related to data centers, electricity, and Bitcoin mining companies such as Applied Digital, IREN, Riot Platforms, and CleanSpark. This pre-thunderstorm ledger presents a set of deals that are highly betting on AI computing power bottlenecks: storage, foundry, cloud computing power, electricity, data centers, and mining infrastructure are bundled in the same direction. At the end of July, it was reported in the market that Situational Awareness was forced to sell most of its open stock positions due to falling AI-related stocks and leverage pressure. Eventually, Citadel took over the problematic stock portfolio, and the market had concerns about the fund's turmoil before. Based on this position, Leopold crushed multiple volatile assets in the AI infrastructure chain into the same super-crowded deal. When AI transactions go smoothly, it's like a myth; when chips, computing power, and power chains retreat together, leverage can quickly turn the myth into an accident. However, it should be emphasized that 13F only discloses US listed securities and some options as of June 30, and does not disclose intraday transactions, the full picture of the bears, the financing structure, and sales after June 30.

Jane Street lost $15 billion in a single month, and AI funds plummeted, causing top trading giants to suffer rare losses

Comparative news, according to the Financial Times, Wall Street quantitative trading giant Jane Street experienced significant losses due to investing in the AI hedge fund Situational Awareness, which lost about $15 billion in a single month in July. People familiar with the matter revealed that Jane Street released the loss data when disclosing the financial situation to creditors. This disclosure is related to a private debt financing transaction of about $146 billion. The deal, led by J.P. Morgan Chase, involved transferring approximately $11 billion of public debt to private investors, including Pacific Investment Management (Pimco). The loss stemmed from a sharp correction in US AI stocks in July. Situational Awareness is an AI-themed hedge fund founded by former OpenAI employee Leopold Aschenbrenner and has received investment from Jane Street. The fund was hit hard during the market reversal and forced to sell part of its public stock positions to Citadel due to its previously concentrated and highly leveraged bets on AI stocks. Despite huge losses in a single month, Jane Street has maintained strong profitability in recent years. According to the data, the company's net transaction revenue for the first quarter of 2026 reached a record of US$161 billion, and net transaction revenue for the full year of 2025 was approximately US$40 billion. Market sources pointed out that this loss is rare for a proprietary trading agency that has been low-key for a long time and has occupied an important position in the global market. Jane Street's subsequent shift to private debt market financing will also reduce the scope of its disclosure of financial information to the public market.

Analysis: AI stock god Leopold only keeps Anthropic holdings, and AGI's long-term belief remains unchanged

Comparatively, AI investor Leopold Aschenbrenner's Situational Awareness Fund cleared almost all of its open market stock positions in late July, retaining only private equity positions in Anthropic. Allegedly, Ken Griffin's Citadel took over most of the stock assets sold by the fund. Situational Awareness's management scale previously reached 45 billion US dollars, but after losing money on AI infrastructure-related stocks, the fund drastically cut public stock positions. With almost all of its public shares being sold, Anthropic became the only core holding that remained untapped. According to reports, Aschenbrenner saw Anthropic's potential IPO as an important catalyst in an investor letter released in July. Anthropic is one of the world's highest-valued private AI companies, and if it goes public in the future, early investors will have the opportunity to exit and redeem their earnings. Analysts believe that Aschenbrenner chose to keep Anthropic's holdings even after experiencing drastic adjustments in AI infrastructure stocks, reflecting his continued optimism about Anthropic and its own AGI long-term investment logic. Currently, Anthropic is not listed, and ordinary investors cannot directly trade its shares. The relevant open market targets in the market mainly include Amazon and Nvidia, both of which have invested heavily in AI infrastructure.

Situational Awareness tells investors that it will not accept new funding for the time being, and Morgan Stanley plans to make it the main brokerage client within a few weeks

Comparatively, Leopold Aschenbrenner's hedge fund Situational Awareness “bursts out”, but instead of deterring investors, the crisis has sparked a new wave of popularity in Silicon Valley. Currently, the fund's remaining asset portfolio (including private equity) is worth about $10 billion. Situational Awareness was previously revealed to be seeking new capital injections due to significant losses in AI-related stocks, but the fund's bursting experience not only did not become a stain in Silicon Valley, but instead strengthened the “heroic personality” of founder Leopold Aschenbrenner. Many Silicon Valley investors saw it as an opportunity to “buy on dips”, and continued to stand as a platform for the former OpenAI researcher's transformed investor. Currently, the fund has told investors that it will not accept new capital for the time being, but the enthusiasm from the outside world is not there any enthusiasm from the outside world As a result, it declined, and senior venture capitalist Elad Gil even publicly announced his first application to invest in Aschenbrenner's fund. Additionally, Morgan Stanley, which previously declined to provide principal brokerage services for Situational Awareness, has changed its position and plans to include the fund as a prime brokerage client within the next few weeks. However, if the high returns from earlier this year are to be reinstated, Aschenbrenner will ultimately have to persuade Wall Street to re-provide leverage. That means he must find a sustainable path between Silicon Valley's enthusiastic support and Wall Street's stringent requirements for risk management. (Wall Street News)

AI fund Situational Awareness throws $400 million bet to return to the investment stage

According to GLONGHUI, a few days after its hedge fund was on the verge of collapse, former OpenAI researcher Leopold Aschenbrenner has returned to the investment stage, throwing $400 million to back a private company. The investment, which was completed on Tuesday, is Aschenbrenner's first signal on how to clean up the mess after the AI hedge fund Situational Awareness almost crashed last week due to the intensive issuance of additional margin notices by many Wall Street lenders. This capital injection is in addition to Situational Awareness's $100 million investment in the same company last month. It's unclear which companies in its private equity portfolio received this additional funding.
