xAI, the artificial intelligence company founded by Elon Musk in 2023, owns X, the social media platform formerly known as Twitter. In March 2025, Elon Musk's company xAI acquired X in an all-stock transaction, effectively merging the two companies into a single entity called X.AI Holdings Corp. Elon Musk is the principal owner of both xAI and X, consolidating ownership under the xAI umbrella. The acquisition was valued at about $33 billion for X, with xAI valued at around $80 billion at the time of the deal. This move aims to integrate xAI's AI capabilities with X's platform to provide enhanced, intelligent user experiences.
