"This is simply not accurate," he said in a reply to a user post about the Bloomberg article on social media platform X.The artificial intelligence (AI) startup xAI is discussing a valuation of $15 billion to $20 billion, though terms could still change in the coming weeks, Bloomberg reported, citing people familiar with the matter.Musk and investors are expected to finalise terms in the next couple of weeks, and some parties are evaluating whether they can get computing power in addition to, or in some cases instead of, xAI equity shares, Bloomberg reported.Last December, Musk said his artificial intelligence company was not raising funds, a day after the startup filed with the U.S. securities regulator to raise up to $1 billion in an equity offering.Musk launched xAI in July last year in response to Big Tech's AI efforts, which he has criticised for excessive censorship and a lack of adequate safety measures.
