Situational Awareness filing shows AI bets before forced portfolio sale to Citadel
A 13F filing for Situational Awareness (Leopold Aschenbrenner) shows large June end holdings in AI-related stocks including Sandisk, Micron Technology, Bloom Energy, Taiwan Semiconductor Manufacturing, and Nebius Group, plus $745m in CoreWeave. These names fell sharply in July, contributing to a liquidity crunch and forced sales to Citadel. Sandisk -47%, Micron -29%, CoreWeave also hit.
How this was made
The 30-second read
Why it matters
Traders can use the disclosed holdings as a positioning and crowding signal for AI-infrastructure names, but the filing itself is backward-looking and does not introduce new company fundamentals.
Market read
New 13F disclosure provides a concrete map of which AI-infrastructure stocks were held before the July AI trade reversal, useful for understanding crowding and risk, but not a fresh catalyst for the companies themselves.
What to watch
The article notes leverage and forced sales, but it does not quantify how much of each stock’s move was fund-driven versus macro/earnings/positioning changes across the whole AI complex.
Background
The article describes a 13F filing for hedge fund Situational Awareness (Leopold Aschenbrenner) showing large AI-infrastructure long positions at end-June, followed by steep July declines and forced liquidation to Citadel.
Ticker impact
13F shows Situational Awareness held Sandisk as a top position at end-June, then it plunged nearly 47% in July during the AI reversal.
Near-term price impact is likely limited because this is a retrospective 13F disclosure, but it reinforces downside risk for similar AI-infrastructure longs.
The article provides a concrete end-June holding and the subsequent July performance, but it does not disclose new operational or financial changes for SNDK.
Micron was among Situational Awareness’s five largest disclosed holdings at end-June, then tumbled nearly 29% in July.
Limited incremental impact from the 13F itself; traders may treat it as confirmation of sector volatility rather than a new catalyst.
The text links the holding to the July selloff but does not introduce new Micron-specific news.
Bloom Energy was a top disclosed holding at end-June and slid 32% in July as the AI trade reversed.
No direct near-term catalyst; relevance is mainly for risk management around similar infrastructure longs.
The article is a 13F-based positioning recap with no new Bloom Energy fundamentals disclosed.
Taiwan Semiconductor Manufacturing was listed among the fund’s largest holdings at end-June and lost 15% in July.
Likely negligible incremental price impact; it is more about validating the magnitude of the unwind than changing TSM’s outlook.
The disclosure is about the fund’s holdings and subsequent price action, not new TSM guidance or events.
The filing also shows Situational Awareness held $745 million of CoreWeave, another AI infrastructure name hit during the July rout.
Potentially modest sentiment impact for CRWV as traders may infer continued volatility for AI infrastructure longs, but no new CoreWeave catalyst is disclosed.
The article provides a specific disclosed position size and ties it to the July liquidity crunch, but it is still a 13F recap rather than a new company event.
Market effects
Reinforces that AI-infrastructure and memory/data-center/power-related longs were crowded and vulnerable to a fast unwind, which can pressure similar names on risk-off days.
Highlights broad exposure across US-listed AI infrastructure proxies, with TSM included as a key component of the AI supply chain narrative.
Supports a global read-through that AI trade reversals can propagate across the stack, from chips to data centers to power infrastructure.
Counterpoint
The 13F is a snapshot at end-June and does not prove causality; the July drawdowns could reflect broader market repricing rather than the fund’s specific positioning.
