Jane Street, a secretive Wall Street trading firm, reported approximately $15 billion in losses during July, marking its first monthly decline in about ten years. This significant downturn was largely attributed to its investment in Situational Awareness, an AI-focused hedge fund, which suffered a major drawdown. Situational Awareness, run by Leopold Aschenbrenner (a former OpenAI researcher), offloaded much of its stock portfolio in a fire sale to Citadel after being impacted by an AI selloff that led to margin calls.
In addition to the Situational Awareness investment, Jane Street also incurred losses from long positions in non-AI stocks in Asia, many of which had previously outperformed the market. AI-exposed stocks, including several large memory and semiconductor companies, saw declines of around 50% during July. Despite this substantial monthly loss, Jane Street has generated over $40 billion in trading revenue year-to-date, according to sources, surpassing many large banks and market-making competitors.
The July losses have highlighted Jane Street's evolving strategy, which now includes longer-term bets akin to a hedge fund, moving beyond its traditional role as a pure-play market-maker. In a note to employees, Jane Street executives acknowledged July as a "bad month" and stated they would be "more selective" about risk going forward, reducing risk-taking in areas that incurred losses.
