A group of investors led by Elon Musk says it is offering $97.4 billion to buy OpenAI, escalating a legal dispute with the artificial intelligence company that Musk helped found.

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

In a contextless post on Musk's X, Altman seems to have rejected Musk's bid. OpenAI has already raised billions of dollars from companies like Microsoft and was last valued at $157 billion. On X, Altman posted, "no thank you but we will buy twitter for $9.74 billion if you want." Altman's quip about buying Twitter was a not-so-subtle jab at Musk.
