OpenAI employees have sold $6.6 billion worth of shares in a recent secondary sale, highlighting the company's immense valuation of $852 billion. Seventy-five employees each sold the maximum allowed $30 million, contributing $2.25 billion to the total. The remaining 525 participants averaged $8.3 million each. This sale is part of ongoing secondary sales since 2021, allowing employees to cash out significant equity before an IPO. These secondary sales are crucial for employees at private companies, converting equity into liquid assets and establishing a market-driven valuation. OpenAI's valuation was determined by investor interest, not internal estimates, setting the stage for a potential IPO valuation exceeding $1.5 trillion.
