OpenAI, the company behind the popular ChatGPT, is reportedly in discussions with the California attorney general’s office about changing its corporate structure to a for-profit model, according to Bloomberg News. This potential move would mark a significant shift for OpenAI, which was initially established as a nonprofit research organization in 2015.

The move, which follows earlier reports in September, would align OpenAI’s business structure with its growing appeal to investors. Microsoft, a major backer, has already supported OpenAI’s rapid development and commercialization efforts.

Sources indicate that OpenAI’s core business could soon become a for-profit company, while its nonprofit arm would continue to operate with a minority stake in the new entity, a Reuters tracking report said. Neither OpenAI nor the California attorney general’s office responded to Reuters’ requests for comment on the matter.

This potential restructuring follows OpenAI’s recent $6.6 billion funding round, bringing its valuation to approximately $157 billion and making it one of the most valuable private companies in the world.
