Situational Awareness hedge fund liquidates leveraged portfolio after semiconductor losses

Decision brief

What changed

Situational Awareness, a leveraged AI-focused hedge fund founded by ex-OpenAI researcher Leopold Aschenbrenner, sold most or all of its public stock portfolio (chip, memory, and energy positions) to Citadel to meet margin calls after semiconductor stocks fell roughly 28-30% in a month. Reported fund assets dropped from a peak of roughly $20-45 billion to about $10 billion, though the fund retained private holdings including a reported $5 billion Anthropic stake.

Why it matters

This is a concrete example of leverage risk materializing in AI infrastructure investing, not a hypothetical: a large, high-profile fund was forced into distressed selling when semiconductor prices dropped sharply. It signals that capital backing the AI buildout thesis (chips, memory, data-center energy) can be fragile under leverage, which matters for treasury and risk officers evaluating AI-adjacent equity exposure, financing partners, and market sentiment toward AI capex-linked stocks.

Evidence

Four outlets (The Verge, TechCrunch AI, The Neuron, Exponential View) independently reported the liquidation and sale to Citadel, with consistent core facts, though asset figures diverge ($20B in three sources vs. $45B in Exponential View) and only Exponential View cites a specific 4x leverage ratio.

What remains uncertain

Sources disagree on the fund's peak size ($20B vs $45B) and only one cites the leverage multiple, so the scale and mechanics of the forced sale are not fully verified; it's also unclear whether the fund continues operating, how the retained Anthropic stake will be valued or monetized, and whether this is an isolated leverage failure or indicative of broader stress among AI-thesis investors.

Monitor next

Watch whether the Philadelphia Semiconductor Index and AI infrastructure stocks continue to decline, which would indicate broader forced deleveraging beyond this single fund.
