AI sell-off and Situational Awareness exposures sees Jane Street take $15bn July hit
TOP STORY: Jane Street suffered a roughly $15bn setback in July as the sharp reversal in artificial intelligence stocks hit the trading firm’s exposure to hedge fund Situational Awareness and other technology positions, according to a report by Reuters.
Jane Street suffered a substantial $15 billion loss in July, as reported by Reuters. The steep downturn in artificial intelligence (AI) stocks significantly impacted the trading firm's positions in Situational Awareness, a hedge fund, and other technology investments, according to unnamed sources and an internal note to employees. The report highlighted that the July decline represented a dramatic shift for a Wall Street giant.
Despite the July setback, Jane Street had already surpassed $40 billion in trading revenue this year, outperforming its $39.6 billion total for the entire year of 2025. The firm made the July losses known via an employee note, stating that the month had been challenging, primarily due to the Situational Awareness drawdown.
Situational Awareness, co-founded by former OpenAI researcher Leopold Aschenbrenner, had been a stellar performer during the first half of the year. However, the AI-related stock decline triggered margin pressure, prompting Situational Awareness to liquidate most of its public-equity portfolio in a distressed transaction with Citadel, a firm led by Ken Griffin. Although the firm's stake remained nearly unchanged for the year, losses had eroded its gains from earlier in the year.
Jane Street typically employs put options to mitigate sharp market declines; however, the firm's protective measures proved less effective in this case, as the AI stock losses unfolded gradually throughout July instead of in a single abrupt shock. The trading firm also incurred losses on long positions in Asian equities outside the AI sector, with many investments having been among its most profitable during the second quarter.
The July performance marked Jane Street's first negative month of trading revenue since 2016, with revenues about 25% lower than their late-June peak. Recognizing the impact of the losses, Jane Street has decided to reduce risk in the areas that triggered the significant declines and has substantially reduced exposure to the specific strategies responsible for the July losses. The firm has also decreased its overall risk-taking.
