(Reuters) - OpenAI's new financing round is expected to come in the form of convertible notes, according to sources with direct knowledge of the matter, who said its $150 billion valuation will be contingent on whether the ChatGPT-maker can upend its corporate structure and remove a profit cap for investors.

The details of the conditions of the $6.5 billion funding, which have not been previously reported, shows how far OpenAI, the most valuable AI startup in the world, has come from a research-based non-profit, and the structural changes it's willing to make to attract ever more investment to fund its expensive pursuit of artificial general intelligence (AGI).
