Sam Altman, OpenAI’s CEO and co-founder, responded that he would not accept and offered to buy X instead

Elon Musk escalated his feud with OpenAI and its CEO Sam Altman on Monday. The billionaire is leading a consortium of investors that announced it had submitted a bid of $97.4bn for “all assets” of the artificial intelligence company to OpenAI’s board of directors.

The startup, which operates ChatGPT, has been working to restructure itself away from its original non-profit status. OpenAI also operates a for-profit subsidiary, and Musk’s unsolicited offer could complicate the company’s plans. The Wall Street Journal first reported the proposed bid.
