Situational Awareness Hedge Fund Collapses Amid AI Infrastructure Stock Selloff
Leopold Aschenbrenner's Situational Awareness hedge fund, once managing $45 billion, faced a rapid collapse due to significant losses in its concentrated positions. The fund had heavily invested in companies supplying infrastructure for the artificial intelligence boom while shorting software firms expected to be disrupted by AI. A reversal of momentum led to steep declines in long positions and unexpected gains on shorts, triggering margin calls and forced sales. The S&P 500 remained near record levels during this turmoil, masking a dramatic shift in market leadership. Morgan Stanley's Momentum Index saw its worst four-day drop ever, surpassing previous major reversals like the dot-com bust or pandemic crash. The iShares MSCI USA Momentum Factor ETF also experienced an extreme swing from best to worst month. Following the selloff, AI infrastructure stocks rebounded as investors interpreted it as a technical dislocation rather than fundamental deterioration. This led to renewed buying in chipmakers and data-center firms.
