Elon Musk announced on Friday that xAI, his AI startup, had acquired X, his social media platform formerly known as Twitter, in an all-stock transaction combining two of Musk’s highest-profile companies.
In a post on X, Musk wrote that the deal values xAI at $80 billion and X at $33 billion, giving the two companies a total value of $113 billion. The new joint entity will be known as XAI Holdings, per Bloomberg.
The goal of the acquisition is to build a social media site with advanced AI features. In other words, Musk claimed that xAI’s acquisition of X will allow xAI to bring advanced “smarter, more meaningful” AI experiences to X’s more than 600 million active users.

xAI and X have been slowly integrating for years. According to Bloomberg, xAI has reportedly used data from X to develop its flagship product, an AI chatbot named Grok that sets itself apart from competitors like ChatGPT and Gemini by incorporating sarcasm and humor. Premium X users were the first to access Grok on X in December 2023.
X and xAI are both private companies, so no details of the deal were made public except for Musk’s post.

X is an established social media company with over 2,000 employees and an expected U.S. ad revenue of $1.31 billion this year, a 17.5% yearly increase. Musk bought the company, then called Twitter, for $44 billion in October 2022. Since then, Twitter has rebranded to X, implemented cost cuts, and added new features, including a subscription service.
Musk founded xAI in March 2023 to understand the universe, the company’s website says. The AI startup raised $6 billion in December and unveiled Grok 3 last month.
Grok is available on web browsers and mobile devices, but it is also integrated into the X platform. X users can use Grok to ask questions, brainstorm, and solve problems by visiting x.com or the X app on iOS or Android and clicking the Grok icon in the navigation bar.
