Embattled hedge fund Situational Awareness invests $400M in chip startup Source Foundry

Hedge fund Situational Awareness has invested an additional $400 million into chip manufacturing startup Source Foundry, bringing its total stake to $500 million. This move comes despite the fund recently selling off a significant portion of its public portfolio following losses in the AI infrastructure sector.
Why it matters
The investment highlights the continued high-stakes capital flow into AI hardware infrastructure despite volatility in the broader AI stock market.
Situational Awareness may have had to sell off the majority of its public portfolio last month, but the AI-focused hedge fund is still making some big bets.
This week, the fund invested $400 million into Source Foundry, a startup founded by Stanford researchers aiming to make chip manufacturing faster and cheaper, according to The Wall Street Journal . That brings its total investment in Source Foundry to $500 million.
Situational Awareness was founded by Leopold Aschenbrenner, a former OpenAI researcher in his mid-twenties who had no trading experience when he launched the fund in 2024. Early returns were reportedly strong, but the fund faced steep losses in recent months amidst the decline in AI infrastructure stocks.
