OpenAI has been trying to negotiate with its top investor for months. Here’s what’s reportedly causing the issues.

Microsoft’s partnership with OpenAI is complicated, and the pair are intertwined both technologically and financially. While it’s been widely reported that OpenAI shares 20 percent of its revenues with Microsoft, there are additional revenue-sharing agreements in place, according to sources who are familiar with the arrangement.

Microsoft, a major investor since 2019, supports OpenAI through Azure and powers tools like Microsoft 365 Copilot with its models. However, tensions between OpenAI and Microsoft have been simmering in recent months, with occasional public clashes.
