Last month, Twitter CEO Elon Musk told employees that they’d be eligible to receive stocks in X Corporation—the new name for the holding company that he initially set up to purchase Twitter—telling them that soon Twitter could be worth $250 billion. More recently, an April court filing shows that Twitter, Inc. has officially merged with X Corp, achieving Musk’s goal of wiping out Twitter Inc. as a company. The court filing confirmed that Twitter, Inc. “no longer exists.” Now, there is only X Corp.

“X,” Musk cryptically tweeted after the news of the merger broke.

Musk’s lawyer, Jonathan Patchen, didn’t immediately respond to Ars’ request for comment.
