[Self-copied from another market] There’s a statement now; the value is non-public and rumored only.

“We formed our partnership with OpenAI around a shared ambition to responsibly advance cutting-edge AI research and democratize AI as a new technology platform,” Satya Nadella, chairman and chief executive officer of Microsoft, said in a statement, which detailed the investment but didn’t disclose the amount. A person familiar with the discussions, who asked not to be identified because the information isn’t public, said it totals $10 billion over multiple years.
