Altman and Musk were OpenAI’s founding co-chairs in 2015, but their relationship has devolved into name-calling, lawsuits and now a near $100 billion bid from Musk for OpenAI.

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.

A consortium of investors led by Elon Musk, that includes Endeavor CEO Ari Emanuel through his personal investment fund, has offered $97.4 billion to buy the nonprofit that controls OpenAI.
