FT reports that Situational Awareness, the $20 billion hedge fund founded by former OpenAI employee Leopold Aschenbrenner, is seeking fresh capital after suffering heavy losses during the recent AI stock rout.

The fund utilized borrowing to magnify returns, a strategy that amplified losses in the downturn. However, the fund was up 439% on a net basis for the year as of the end of June. In a letter to investors, Aschenbrenner pointed to the prospect of major AI developments in the second half of the year.
