Leopold Aschenbrenner's Situational Awareness fund peaked around forty-five billion dollars in early July two thousand twenty-six, after a four hundred thirty-nine percent net return through June. It was running about four times leverage on a concentrated AI infrastructure book, long names like Nebius, SanDisk, Micron, and SK Hynix, while short software names like Adobe. July's AI selloff hit both sides at once, triggering margin calls from Goldman, JPMorgan, and Bank of America. On July thirtieth, Citadel bought the entire roughly sixteen billion dollar public equity book in one block trade, beating out Millennium and Jane Street. The fund keeps its roughly five billion dollar private Anthropic stake and will continue as a smaller private vehicle. Reports of four hundred times leverage or a ninety percent loss appear to be exaggerations; the confirmed figure is around four times leverage with a drop from forty-five billion to about ten billion in assets. The wedding timing is real. His fiancée, Avital Balwit, is chief of staff to Anthropic's CEO Dario Amodei, and two sources confirmed the wedding is this weekend.
