Hedge fund by ex-OpenAI researcher boosts BTC mining investment to $5.5B

A hedge fund founded by former OpenAI researcher Leopold Aschenbrenner has increased its investment in Bitcoin mining companies to $5.52 billion, Cointelegraph reported. In a recent filing with the U.S. SEC, the fund, Situational Awareness, disclosed that its holdings in these firms grew from $383 million in early 2025. The fund's portfolio includes a total of 29 stocks, with notable investments in Bitcoin mining infrastructure companies such as CoreWeave and Core Scientific. However, Cointelegraph noted that many of these companies are pivoting from Bitcoin mining to AI infrastructure, suggesting the investment may be more focused on AI than on Bitcoin.
