Microsoft and Apple have decided not to take board seats at OpenAI amid growing regulatory scrutiny. Microsoft, after investing $13 billion in OpenAI in 2023, has withdrawn its observer role on the board, stating confidence in the company’s direction. Apple also chose not to join the board, reversing earlier plans to integrate OpenAI’s technologies. This move comes as regulators closely examine Big Tech's investments in AI startups, raising concerns about industry dominance and potential antitrust issues​.
