Situational Awareness LP - Leopold Aschenbrenner 2026 : The Fund That Was Honest About Everything and Still Got Margin-Called - Extra File T1

Three numbers got called "the size of the fund" this year. Almost nobody asked which one they meant.Number one: roughly $20-24B in actual investor capital. Number two: close to $45B in gross exposure once leverage got layered on top, at roughly 4x. Number three, reported this week: something closer to $10B left after a forced, six-day unwind.That's Situational Awareness LP — the AI-infrastructure fund built by 25-year-old Leopold Aschenbrenner, ex-OpenAI, off the back of a viral essay on AGI timelines. Through June, it posted a 439% net return for the first half of the year alone. Six weeks later, it sold its entire public book — longs and shorts together — in a single overnight block trade to Citadel.Nobody in this story has been accused of hiding anything. The 13F was public. The leverage was disclosed in investor letters. That's what makes it worth studying — not despite the lack of fraud, but because of it.Full disclosure of each individual fact — capital, leverage, positions — doesn't automatically add up, in a reader's head, to the one number that actually determines survival: total leverage against total available cushion, correlated across every position and every lender at once. Three prime brokers, each seeing only their own slice of the leverage. A long book and a "hedge" that both depended on the same AI-infrastructure thesis moving the same direction — so when it reversed, both legs fell together instead of offsetting.Roughly the same structural blind spot that sat underneath Archegos in 2021. Different case, no alleged concealment this time, same gap: no single institution sees a fund's aggregate cross-broker leverage by default.We built this one as a live case file — numbers as of July 31, still moving, treated as a snapshot, not a verdict. Full breakdown, mechanism-first, in the podcast. T1 has the story, T2 has the GP/LP diligence framework for anyone extending prime brokerage credit or LP capital to a fast-growing, single-thesis fund.This episode is a extra of Financial Forensics Labs — two shows, one forensic methodology: The Due Diligence Files traces how institutions collapse, The Signal Files traces how the good calls get made.
