Former OpenAI Employee's Fund Hit by Leveraged Bets on AI Stocks, Seeks Emergency Financing
Taylor Wilson
Situational Awareness, a $20 billion hedge fund founded by former OpenAI employee Leopold Aschenbrenner, is scrambling for fresh capital after heavy losses on leveraged AI stock positions — drawing market comparisons to the 2021 Archegos blowup.
What happened to this fund?
Situational Awareness posted a 439% net return in the first half of the year, but several of its concentrated AI holdings have since plunged, triggering margin-call pressure.
In a July 24 investor letter the fund conceded it was "not immune" to market swings and offered investors a window to inject new capital by August 1.
This means → the same leverage that supercharged first-half gains is now amplifying losses in the other direction.
Which positions got hit hardest?
The fund held a multi-billion-dollar stake in AI cloud platform Nebius Group NV, whose stock has fallen 48% from its recent high, erasing roughly $35 billion in market cap.
Its Sandisk Corp. position dropped 56% in just over a month; another holding, SharonAI Holdings, fell by a similar margin since mid-June.
In plain terms = three core positions were nearly cut in half at the same time — a hyper-concentrated portfolio with no cushion in a downturn.
What are the Wall Street banks doing?
According to CNBC, prime brokers including Bank of America, Goldman Sachs, and JPMorgan are helping the fund manage margin calls or unwind positions in an orderly fashion.
The banks marketed the fund's long and short holdings to buyers before the market opened; some investors were also offered the option to buy portfolio assets directly.
This means → the banks are trying to prevent a disorderly fire sale that could ripple through the market. The fund has denied the reports.
Why is the market comparing this to Archegos?
In 2021 Archegos used total return swaps — TRS, a derivative that lets a fund control large stock exposures with relatively little capital — to build massive leveraged positions. When it failed to meet margin calls, multiple prime brokers raced to dump shares, triggering a systemic shock.
Archegos founder Bill Hwang was subsequently sentenced to 18 years in prison.
This reflects broader anxiety over leveraged AI bets — the true scale of AI-sector leverage and prime brokers' TRS exposure will become clearer in about 15 days, when the next round of 13F filings is due.
