Jane Street makes rare investment, with OpenAI researcher's fund size surpassing $20 billion before the age of 24 According to Beating monitoring, the Situational Awareness AI fund founded by former OpenAI researcher Leopold Aschenbrenner has exceeded $20 billion in scale, and quantitative giant Jane Street has made rare investments. After deducting expenses, Situational Awareness achieved a return rate of 270% within the year, with a cumulative return of over 1000% since its establishment. The equity bet on Anthropic contributed the most successful returns, accounting for one-fifth of the assets. When the initial capital injection was made in February 2025, the valuation was only $61.5 billion, but now it has soared to $965 billion. The performance is also accompanied by drastic fluctuations. At the beginning of 2025, Chinese startup DeepSeek's release of a low-cost model triggered a sell-off in chip stocks, resulting in a temporary loss. Subsequently, the explosive demand for computing power and power infrastructure drove the recovery of performance, recording a full year profit of 200% at the end of the year. Position changes have sparked heated discussions on social media platforms. The quarterly 13F position report is regarded as a barometer by retail investors, and the copy tracking software Autopilot even launched a one click copy function for Aschenbrenner trading in March. The disclosure of T1 Energy's holdings in May, a solar manufacturing company, further propelled the target stock to soar 23% in a single day. Outside of the public market, Situational Awareness has also partnered with Jian Street to lead investment in AI chip company MatX and participate in a new round of financing for AI cloud computing company Fluidstack. With the expansion of asset size, the team recently recruited Niki Webster, former head of Goldman Sachs, as the head of investor relations, and Sven Khatri, former trader at Citadel, as the head of fund strategy.
