Jane Street, a prominent Wall Street trading firm, sustained a $15 billion loss in July due to its exposure to Situational Awareness, an AI-focused hedge fund, and a broader market decline in semiconductor and tech stocks. Despite the drawdown, the firm maintains over $40 billion in trading revenue year-to-date, according to sources familiar with the matter and a company note seen by Reuters.
Market Volatility and the Situational Awareness Drawdown
The losses were primarily driven by a sharp downturn in the tech sector, which hit Jane Street’s long positions in semiconductor and memory stocks. According to a note sent to employees, these specific assets experienced declines of approximately 50% during July. The firm characterized the month as a “bad month” for its trading performance, noting that the drawdown at Situational Awareness—an externally managed fund—contributed significantly to the deficit.
Situational Awareness is led by Leopold Aschenbrenner, a former OpenAI researcher. Following the AI sector selloff, the fund faced margin calls and ultimately executed a fire sale of its stock portfolio to Citadel, the hedge fund founded by Ken Griffin. Jane Street, which counts itself as an investor in Situational, reported that its stake in the fund is currently flat for the year, though it remains up when measured against the total duration of the investment.

Leopold Aschenbrenner, who manages the Situational Awareness hedge fund, has been nicknamed the “Nostradamus of AI” by industry observers due to his previous work and research on artificial intelligence development.
Trading Revenue and Risk Management Strategy
Despite the July losses, Jane Street continues to outperform many of its market-making rivals and large banking institutions. The firm has generated more than $40 billion in trading revenue year-to-date, according to one source familiar with the internal figures. This revenue cushion has allowed the firm to absorb the volatility associated with its tech-heavy portfolio.
In response to the market conditions, Jane Street executives informed staff that the firm is shifting its approach to risk. The company has already closed a significant portion of its positions in the sectors that underperformed in July. Moving forward, the firm plans to be “more selective” regarding risk-taking and will reduce exposure in other, unnamed strategies to stabilize performance.
Large trading firms often use “risk-off” periods to rebalance portfolios. When volatility spikes in specific sectors like semiconductors, institutional investors frequently liquidate underperforming assets to protect capital reserves.
