# Leopold Aschenbrenner's AI hedge fund Situational Awareness sells its public stock book to Citadel after July AI-stock rout

Around 2026-07-30 Situational Awareness LP, the fund launched by ex-OpenAI researcher Leopold Aschenbrenner, author of the 2024 "Situational Awareness" essay, had to sell nearly all its leveraged public stock positions to Ken Griffin's Citadel at a discount, after AI-infrastructure stocks such as SK Hynix, CoreWeave and Micron fell more than 35% in July. CNBC reported assets falling from as much as $45B to about $10B. It kept private holdings, including Anthropic.

## Key facts
- CNBC (2026-07-30): fund forced to unwind all public stock positions after steep AI losses; CNBC (2026-07-31): '$45B to fire sale'
- WSJ via Yahoo Finance (2026-07-30): Citadel bought the bulk of the listed holdings; Millennium also bid; price not disclosed
- Reported leverage of up to ~4x (400%); the public book sold was estimated at roughly $16B; assets after the sale about $10B (reports differ: WSJ put peak AUM at 'more than $20 billion', CNBC at $45B)
- Strategy: long memory chips, data centers and power (SK Hynix, Sandisk, Micron, CoreWeave, Nebius, IREN, Core Scientific, Bloom Energy), short software exposed to AI disruption
- Before July: >1,000% since inception (WSJ, June) and a reported 439% net in H1 2026
- Private positions such as Anthropic were not part of the sale
- Aug 24, 2026: Bloomberg reported (people familiar) that the SEC subpoenaed Goldman Sachs, JPMorgan, Citigroup and Bank of America for the timing of the fund's trades, its leverage and its communications with lenders, and told them to preserve records; Situational Awareness responded in a statement (via Disruption Banking)

## What happened

A fund built directly on the "AGI is coming, buy the compute supply chain" thesis grew very fast on leverage. It unwound in
one block trade when AI-infrastructure stocks fell sharply in July 2026, the same month as the OpenAI–Hugging Face incident.

## Why it matters

It was the biggest market casualty of the AI-infrastructure trade so far, and a sign of how much capital was riding on
short AGI timelines. Reports say AI stocks rose once the forced seller was gone, so it was a leverage event more than a
verdict on AI. AUM figures differ between outlets (gross exposure vs net assets); treat all headline numbers as approximate.
