Ken Griffin's Citadel purchased most of the stock holdings from Situational Awareness, an AI-focused hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, after the fund suffered heavy losses in its technology investments.
Leopold Aschenbrenner's hedge fund Situational Awareness rapidly sold most of its public equity holdings to Citadel after assets plunged from $45 billion to $10 billion in one month during the AI stock selloff. The fund was founded by the former OpenAI researcher with no prior hedge fund experience.
After the Ethereum community rallied behind Danny Ryan in an on-chain vote representing over $159 million in ETH, Ryan and the Ethereum Foundation mutually parted ways in January 2025 without a leadership arrangement. Rather than returning to the organization he helped build for seven years, including leading The Merge, Ryan co-founded Etherealize in March 2025 alongside former Citadel executive Vivek Raman, focusing on bringing Ethereum to Wall Street.
