Last March, Musk filed a lawsuit claiming OpenAI, a global leader in artificial intelligence innovation which has developed the ChatGPT chatbot, DALL-E image generator and other advanced AI-driven tools, breached promises made in its founding documents and prioritizes profit motive over serving the public good.

The billionaire is leading a group of investors in the unsolicited offer, which complicates the start-up’s plan to raise more money.

The group’s $97 billion offer is far lower than the OpenAI’s most recent valuation by investors. OpenAI CEO Sam Altman rebuffed the offer in a post on X.
