Twitter has ceased to be an independent company after merging with a newly formed shell firm called X Corp., driving speculation about what Elon Musk intends for the social media platform.

Twitter "no longer exists” after being merged with X Corp., according to an April 4 document submitted in a California court for a lawsuit filed against the company and its former chief executive officer, Jack Dorsey, last year by conservative activist Laura Loomer.

It’s unclear what the change means for Twitter, which has seen a sweeping overhaul since Musk bought the company for $44 billion last year. The billionaire owner has in the past suggested that buying Twitter would be an "accelerant” for creating X — which he dubbed an "everything app.” Musk tweeted about the move Tuesday with the single character "X.”
