UK competition watchdog to review Microsoft and OpenAI partnership

The UK's competition watchdog has paved the way for a formal investigation into the partnership between Microsoft and ChatGPT developer OpenAI by asking for comments on the arrangement. The Competition and Markets Authority made the announcement on Friday after a bout of leadership and boardroom turmoil at OpenAI, which is based in San Francisco. The company was established as a non-profit entity whose board controls a commercial unit, in which Microsoft is the biggest investor. The CMA said "recent developments" had prompted the organisation to review whether the partnership had resulted in "an acquisition of control". Last month, OpenAI's board fired and then reappointed its chief executive, Sam Altman, and announced the formation of a new board. Microsoft now has a non-voting observer seat on the OpenAI board.
