Up 439%, Then Margin-Called: Did Leopold Aschenbrenner’s Situational Awareness Actually Blow Up?

Leopold Aschenbrenner’s hedge fund, Situational Awareness, reportedly surged 439% in six months before suffering a margin-call-driven unwind of its public stock portfolio. CNBC and Bloomberg said the fund, which had grown to about $45 billion by early July, sold all public equity positions, later bought by Citadel. The article highlights that the fund’s disclosed holdings had shifted rapidly toward Bitcoin miners and AI/power infrastructure, with miners rising from 0% to roughly a quarter of the portfolio. It argues the selloff reflected both leverage pressure and a broader AI-stock correction, not a single market conspiracy. The piece frames the event as potentially bullish for Bitcoin miners and related AI infrastructure stocks over the medium term, but bearish for near-term sentiment in AI and chip names after a sharp July pullback.
