About OpenAI

OpenAI is an American artificial-intelligence company founded in 2015 and headquartered in San Francisco. It is led by chief executive Sam Altman and is best known for the GPT family of large language models, the ChatGPT assistant, the Sora video model and an API used by developers and enterprises. The company operates as a capped-profit business controlled by a non-profit foundation, and counts Microsoft, Amazon, Nvidia and SoftBank among its investors. OpenAI remains privately held; Altman said in September 2026 that a 2026 listing would be "ill-advised" given the company's safety work. Shares are not publicly traded, and the pre-IPO perpetual futures referenced on this page are synthetic derivatives that convey no ownership, voting rights or dividends.
