Elon Musk on Friday evening announced he has sold his social media company, X, to xAI, his artificial intelligence company, in a deal that values X at $33 billion, much less than he paid for it in 2022 but a significant rebound from its moribund valuation just a few months ago.

Elon Musk announced Friday that his company xAI is buying X, the social media platform formerly known as Twitter, in an all-stock deal. The transaction values xAI at $80 billion and X at $33 billion, according to CNBC.

The move will “unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach,” he wrote on X.

Elon Musk's AI company, xAI, has purchased X, according to a post shared by Musk. Besides their similar names and owner, the companies are already connected through xAI's chatbot Grok, which is integrated into X.

Musk said that xAI has acquired the social-media platform in an all-stock deal valuing the AI company at $80 billion and X at $33 billion.

Elon Musk’s artificial-intelligence startup xAI has acquired X, the social-media platform he also owns, in an all-stock deal that assigns the new enterprise a lofty valuation.

Both companies are privately held, which means they are not required to disclose their finances to the public.

Musk said in a post on X that the move will “unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.” He said the deal values xAI at $80 billion and X at $33 billion.

The combination values xAI at $80 billion and X at $33 billion,” he wrote in an X post on Friday. The X value is $45 billion when including $12 billion of debt, he said. It was an all-stock transaction.
