According to the Financial Times, the AI hedge fund founded by former OpenAI researcher Leopold Aschenbrenner has been severely hit by the recent plunge in AI tech stocks and is currently negotiating with existing investors and lenders for new capital. The fund previously utilized borrowed leverage and posted massive gains in the first half of the year, but the recent market correction has forced it into a rescue effort. This incident highlights the massive volatility risks associated with highly leveraged bets on AI concept stocks.
