OpenAI has raised $3 billion from retail investors as part of a broader $122 billion fundraising round — the first time the company has opened its cap table to individual investors at scale. The round values OpenAI among the most valuable private companies in history.
For Sam Altman, the retail component carries symbolic weight: it frames AI’s most prominent lab not as an instrument of institutional capital but as a broadly held bet on the future. Co-founders Greg Brockman and Ilya Sutskever helped build the technical foundation that commands this valuation.
The sheer scale of the raise places OpenAI in a category of its own among AI labs, giving it the capital to pursue compute, talent, and research ambitions that smaller rivals cannot match.
