OpenAI's board on Wednesday questioned the rationality of a $97.40 billion offer from Mr. Musk and others to buy the company. On Monday, a consortium of investors led by Mr. Musk offered to buy assets of the nonprofit that controls the company, intensifying a years-long feud between Mr. Musk and OpenAI chief executive Sam Altman. In a court filing on Wednesday, the company said Mr. Musk's offer contradicted its legal claims in a lawsuit it filed against OpenAI last year. OpenAI argued in the filing that Mr. Musk was accusing Mr. Musk of hypocrisy by saying in the suit that assets must remain with the nonprofit and could not be transferred to another entity for the public good. Mr. Musk had previously argued in the suit that OpenAI must be managed by the nonprofit, but now he has made the opposite argument. OpenAI's board has not formally rejected the offer.
