Elon Musk’s X platform is introducing a new ‘Username Marketplace’ for its premium users, offering access to inactive usernames via a user-controlled marketplace. The two categories of available usernames are Priority and Rare. Priority usernames are free and offer names, phrases, or alphanumeric combinations, while Rare usernames require payment, with prices ranging from $2,500 to significantly high figures based on demand and uniqueness. Once a username is successfully changed, the original one will be permanently frozen. Users who downgrade their subscription will automatically revert to their original username. X has also mentioned exploring the possibility of offering a paid redirection feature in the future.
