Twitter now directs to X.com in the latest step in Musk's rebrand of the platform

• Elon Musk just took the next step in rebranding Twitter as X.
• Twitter.com now redirects to the X.com domain.
• Musk has had a fascination with using the letter X for his businesses dating back to at least 1999.

Social media users trying to access Twitter may notice something different today: Typing in Twitter.com now redirects to the X.com domain.

Platform owner Elon Musk confirmed the change in a post early Friday morning, saying, "All core systems are now on X.com."

A popup message alerting users to the change reads: "We are letting you know that we are changing our URL, but your privacy and data protection settings remain the same."

Previously, there was still some back-and-forth with the URLs: You'd still see the Twitter.com URL if that's what you typed to access the site, but using the Share button on a post produced a link that started with X.com, for example.

And some users are still seeing the Twitter.com domain — though it's not clear how long that'll last.

The change marks the latest step in Musk's rebrand of Twitter to X since buying the platform in 2022.

Last year, he ditched Twitter's famous blue bird logo for an X and said posts on the platform should no longer be called "tweets" but instead "Xs."

Musk has long talked about his plans for an "everything" app called X that he envisions would take inspiration from Tencent's WeChat.

"If you're in China, you kind of live on WeChat," he's said. "It does everything — sort of like Twitter, plus PayPal, plus a whole bunch of things, and all rolled into one, with a great interface. It's really an excellent app, and we don't have anything like that outside of China."

Musk has also used the letter X in the branding of his other businesses.

Last year, he launched a company called xAI, for example. But his fascination with X for his businesses dates back decades: In 1999, Musk cofounded a financial services business with the domain X.com that would ultimately become part of PayPal through a merger. Not to mention, he runs SpaceX.
