FTX, the cryptocurrency exchange, missed substantial investment opportunities in early-stage AI companies Anthropic and Cursor AI. FTX had early stakes in these firms but sold its positions prematurely, resulting in losses estimated at around $7.6 billion. For example, FTX sold its stake in Cursor AI for approximately $200,000, while the company's valuation has since surged to about $500 million after a recent $900 million funding round. Sam Bankman-Fried (SBF), the founder of FTX who is currently serving a 25-year prison sentence for fraud, was an early investor in both Anthropic and Cursor AI, completing seed rounds before the AI boom driven by technologies like ChatGPT. Despite his legal troubles, some industry voices have recognized SBF's early investment acumen, although others criticize the narrative that he built one of the best private investment portfolios, pointing out losses and the misuse of customer funds to fuel his bets.
