Musk’s favored ticker, X, is available for the taking in a SpaceX-Tesla deal, according to Bloomberg. Elon Musk has an affinity for the letter: Tesla’s Model X was one of its first vehicles, and SpaceX uses the name. Twitter was renamed X after Musk acquired the platform in 2022. He also named his son X Æ A-Xii and often refers to him online as “lil X.”
