Sam Bankman-Fried's $500 million investment in AI company Anthropic could have yielded a $30 billion return, had it not been for his legal troubles. In 2022, SBF, through Alameda Research, invested in Anthropic's Series B round, acquiring an 8% equity stake. Today, Anthropic's valuation has soared to $380 billion, making that stake potentially worth over $30 billion. Anthropic, now a major player in AI, recently completed a $30 billion Series G funding round. Despite SBF's arrest and the collapse of FTX, his investment in Anthropic highlights the potential for massive returns in the AI sector. However, the funds used were customer deposits from FTX, leading to legal consequences for SBF, who is serving a 25-year prison sentence.
