AI-focused hedge fund Situational Awareness, led by former OpenAI researcher Leopold Aschenbrenner, has raised its stake in Bitcoin miner Core Scientific to 9.4%. The fund has acquired over 10 million shares since September, with purchase prices ranging from $17 to $19 per share, including a recent acquisition of 2.3 million shares at $19.07 each on October 14. This move comes ahead of Core Scientific's upcoming vote on a merger with AI cloud operator CoreWeave, scheduled for October 30. The merger is expected to grant CoreWeave a controlling interest and facilitate Core Scientific's shift towards high-performance computing services.
