Nadella came to X to express Microsoft’s and OpenAI’s current relationship and the hiring of Sam Altman and Greg Brockman and stated; Despite a major push by investors and negotiations to bring Altman back as the CEO of OpenAI, the board decided to stick with their decision. For Altman’s replacement, OpenAI’s board appointed former Twitch CEO and co-founder Emmett Shear to lead OpenAI. Microsoft and Sam Altman have had a close relationship since the company integrated OpenAI technology into its services. Additionally, Microsoft has invested $10 billion in OpenAI since its launch, and with Altman’s appointment, it seems like the partnership will grow even more.
