US to probe near-collapse of AI Prophet's hedge fund, which once saw 439% gain

US Securities and Exchange Commission has subpoenaed banks that did business with hedge fund Situational Awareness, Reuters reported. Founded by ex-OpenAI researcher Leopold Aschenbrenner, the fund gained 439% in the first six months of 2026 before suffering heavy losses in AI infrastructure stocks. The SEC is reportedly communicating with Goldman Sachs, JPMorgan, Citigroup and Bank of America.
