Can you buy OpenAI stock?
Why there is no OpenAI ticker
OpenAI, the maker of ChatGPT, is one of the most searched-for stocks that does not exist. The company is controlled by a nonprofit-rooted structure with a for-profit arm, and its shares are held by employees and a small circle of institutional investors.
Secondary share sales in late 2025 reportedly valued the company at around $500 billion, which would make it one of the most valuable private companies ever. None of that is buyable on an exchange.
