Leopold Aschenbrenner, the former OpenAI researcher who turned an essay about the coming age of artificial general intelligence into a hedge fund, is unwinding his public market bets as AI stocks sell off.

According to Seeking Alpha, Aschenbrenner's fund has been closing out public positions amid what the outlet describes as an AI market rout — a broad decline that has also hit AI-themed index products such as the AIQ ETF on the Nasdaq.

The Financial Express reports the scale of the reversal in blunt terms: Aschenbrenner's fund, named Situational Awareness after the manifesto that made him famous, fell from $45 billion to $10 billion. The outlet attributes the collapse to volatile AI stocks and risky investments, and notes the drawdown unfolded during the week of his wedding.

The two accounts describe the same arc from different angles. One is about mechanics — a fund selling down what it can sell quickly. The other is about magnitude, and the speed at which a concentrated bet on one theme can reverse.

Aschenbrenner's pitch was never subtle. He argued that AI progress was being systematically underpriced by markets, and he raised money to trade on that conviction. That is a thesis that works spectacularly while sentiment runs one direction and painfully when it turns.

Neither source, as summarized here, details which specific positions were unwound, over what period the decline occurred, or what the fund's investors have recovered. Those details matter and are not yet on the record in these reports.

Why it matters: when one of the loudest, most concentrated bets on the AI boom loses most of its value this fast, it is a live test of whether the market's enthusiasm for AI is an investment thesis or a mood — and ordinary investors hold the same theme through index funds and ETFs.
