Elon Musk has an affinity for the letter X. One of Tesla Inc.’s first vehicles was the Model X. Space Exploration Technologies Corp. goes by SpaceX. Twitter was rechristened as X after Musk acquired the social media platform in 2022. He even named his son X Æ A-Xii and often refers to him as “lil X” online.

Now, as the world’s richest man explores a combination between his two public companies, the market has left an opportunity for the taking: no stock currently trades under the ticker X, which was orphaned after United States Steel Corp. was acquired last year. Though it’s unknown if Musk will attempt to nab that symbol, or if a Tesla-SpaceX tie-up will even go through, investors and analysts have zeroed in on the auspicious timing.
