On 17 May, Elon Musk tweeted that all core systems of X (formerly Twitter) will now be x.com. 

Musk has a long history with the x.com URL, launching a business under the name in 1999 that eventually merged with what would become PayPal. 

The domain transition has been long awaited. Although many aspects of X migrated to the new branding long ago — including its official account, its mobile apps, and its 'X Premium' subscriptions — the platform’s URLs have remained twitter.com ever since Musk officially initiated the switch to X in July 2023. 

The rebranding to X signifies a major transformation, aligning with Musk’s long-term vision of evolving the platform into an 'everything app'.

This change is a key component of a larger strategy to unify the platform's identity under the X brand, to create a cohesive and streamlined user experience. Transitioning to X.com is a crucial step in establishing this new brand identity, highlighting Musk’s dedication to reshaping the social network. As the transition continues, users can expect additional updates and refinements to fully integrate the X branding across all facets of the platform.
