Elon Musk has sold X (previously Twitter) to his own artificial intelligence business, xAI, in an all-stock deal worth $33 billion.

Elon Musk has sold the social media site X (previously Twitter) to his own artificial intelligence business, xAI, in a $33 billion all-stock transaction, he said on Friday.

Because both firms are privately held, they are not obligated to disclose financial information to the public.

In a post on X, Musk said the deal will “unlock immense potential” by combining xAI’s advanced AI technology with X’s wide-reaching platform. He also revealed that the deal values xAI at $80 billion and X at $33 billion.

Musk initially purchased Twitter for $44 billion in 2022, then significantly altered it, including reducing employees, revising policies regarding hate speech and disinformation, and rebranding it X. He introduced xAI a year later.

“X and xAI are closely related,” Musk said. “This combination unites data, technology, computing power, and talent, enabling us to provide smarter and more significant experiences while remaining dedicated to truth and knowledge.”

It’s unclear how this will impact X users, as xAI already uses X’s data to train its AI models. Paying X users can access xAI’s chatbot, Grok, while free users can ask it up to 10 questions every two hours.

This article was first published on March 28, 2025. It was revised on March 29, 2025, to make it clear that Grok has already been accessible to nonpaying X users with certain restrictions. The previous version misstated that only paying subscribers could use Grok.
