What just happened? Elon Musk has orchestrated another move in his sprawling business empire, announcing on Friday that his artificial intelligence firm, xAI, has acquired X (formerly Twitter). The all-stock transaction values X at $33 billion, including $12 billion in debt, and xAI at $80 billion, creating a combined entity Musk says will "unlock immense potential" and provide "smarter, more meaningful experiences" for users.
