The Margin-Call Liquidation of a 450 Hundred-Million-Dollar Fund: Situational Awareness in July (month 7), 2026
Using filings and coverage as the record, this case reconstructs July (month 7), 2026, when a 4x-leveraged AI fund lost about 350 hundred-million dollars in a month and handed its entire public book to Citadel.
Updated Oct 22, 2026
Established facts
Situational Awareness LP is an AI-focused hedge fund founded in 2024 by Leopold Aschenbrenner with early backing from Patrick Collison, John Collison, Daniel Gross, and Nat Friedman. Assets stood at about 450 hundred-million dollars in early July (month 7) 2026, then fell by about 350 hundred-million dollars during July (month 7) as AI infrastructure names sold off, and the fund sold its entire public equity book on July (month 7) 30-31, 2026. Citadel took about 80% of the block at 10% below market, a sale reported at about 160 hundred-million dollars. Private holdings led by the Anthropic stake were untouched by the margin calls, leaving about 100 hundred-million dollars. In August (month 8) 2026 the U.S. SEC began examining the trades, margins, and exposures of Goldman Sachs, JPMorgan, Citigroup, and Bank of America, and in September (month 9) 2026 JPMorgan was reported to have ended lending to the fund.
What stands out
With longs and shorts riding the same AI thesis under up to 4x leverage, a 35% pullback became a total loss of equity. The next-day rebound of more than 20% in core names separates the verdict on the thesis from the verdict on the borrowing structure. Simultaneous margin calls from 3 prime brokers plus predatory shorting show how a liquidity crunch accelerates price declines.
Limits
Some figures in the video, such as the up to 4x leverage and single-name gains and losses, rest on a single narrative and should not be quoted as confirmed numbers. A post-liquidation bounce does not guarantee that the next drawdown in the same structure will recover.
