According to CoinMeta, former Bloomberg journalist Jack Clark has become a co-founder of Anthropic, with an estimated fortune of $15.5 billion. Clark transitioned from Bloomberg to OpenAI in 2016 and later co-founded Anthropic with former colleagues, focusing on the development of secure artificial intelligence systems. Based on Forbes's estimates, Clark holds approximately 1.6% of the shares in Anthropic; his wealth mainly comes from his initial investment in the company rather than direct participation in the development of AI's models. Anthropic raised $65 billion in its funding round in May 2026, with a valuation of $965 billion, making it one of the most valuable private companies in the industry.
