OpenAI: Altman Returns; Microsoft Gains Observer Seat
OpenAI announced the official return of Sam Altman to the company and granted Microsoft a non-voting observer seat on its board. The move comes after earlier tensions that led to Altman's departure. Altman conveyed optimism about OpenAI's future in a staff message, while board chair Bret Taylor outlined the next steps. The reconstituted board includes Bret Taylor, Larry Summers, and Adam D’Angelo, with three of the four former directors who voted to remove Altman no longer serving. Microsoft previously held a 49% stake in OpenAI and now gains closer visibility into internal processes through the observer seat, without voting rights. The development signals renewed governance alignment as OpenAI pursues its AI initiatives and partnerships.

Satya Nadella on Microsoft–OpenAI Deal Control
A Tech Emails newsletter published internal messages and attachments from Microsoft and OpenAI executives that appeared in Musk v. Altman court filings.

The archive also includes April 2022 and November 2023 exchanges between Sam Altman, Nadella, Kevin Scott and others about deal structure, embedding Microsoft personnel, IP rights, funding models, and possible OpenAI board compositions during Sam Altman’s November 2023 board crisis.
