OpenAI is talking to investors about a possible share sale that would value the artificial-intelligence startup behind ChatGPT at between $80 billion to $90 billion, almost triple its level earlier this year, WSJ reported Tuesday, citing people familiar with the discussions. From the report: The startup, which is 49% owned by Microsoft, has told investors that it expects to reach $1 billion in revenue this year and generate many billions more in 2024. OpenAI generates revenue mainly by charging individuals for access to a powerful version of ChatGPT and licensing the large language models behind that AI bot to businesses.
