In a significant financial move, more than 600 current and former employees of OpenAI sold shares totaling $6.6 billion in a secondary transaction in October 2025. This sale has led to a valuation of the artificial intelligence company at around $400 billion. The transaction enabled eligible employees to liquidate parts of their equity holdings, providing liquidity without necessitating a public offering. Notably, approximately 75 participants took advantage of the opportunity to sell the maximum permitted amount of $30 million each. This secondary sale reflects the growing interest and value in the AI sector, as well as the financial strategies available to employees in high-value tech companies.
