Why Did Twitter Change to X? The Full Story (2026)

Twitter changed its name to X because Elon Musk, who has owned the network since October 27, 2022, wanted to turn it into an “everything app” modeled on China’s WeChat: messaging, video and payments in one place. In his view, a name built around 140-character messages no longer fit that plan. Musk announced the change on July 23, 2023, and the blue bird was gone the next day. The letter itself goes back to 1999, when X.com was the name of his online bank. If you’re restarting an account on the new platform, our X followers help you avoid starting from zero.

How did Elon Musk buy Twitter?

It started in spring 2022. On April 4, a filing with the US Securities and Exchange Commission showed that Musk owned 9.2% of Twitter. Ten days later, on April 14, he offered to buy the whole company at $54.20 a share. The board accepted on April 25, in a deal worth about $44 billion.

Then Musk tried to walk away. On July 8, 2022, he said he was terminating the agreement, accusing Twitter of understating the number of fake accounts. Twitter sued him in Delaware to force the sale through. With a trial set for October, Musk went back to his original offer, and the deal closed on October 27, 2022. That same evening he fired CEO Parag Agrawal and several other executives.

Something few people remember: the rename was in the works long before summer 2023. On October 4, 2022, Musk posted that “buying Twitter is an accelerant to creating X, the everything app.” In spring 2023, Twitter, Inc. was merged into a new entity, X Corp. The company was already called X while the app still had its bird.

When did Twitter become X?

The switch happened over one weekend. On Sunday, July 23, 2023, Musk posted: “And soon we shall bid adieu to the twitter brand and, gradually, all the birds.” On Monday, July 24, a white X on a black background replaced the blue bird on the website, and x.com started redirecting to the platform. The same day, workers began taking down the sign on the San Francisco headquarters.

The bird even had a name inside the company: Larry, after basketball player Larry Bird. Its replacement is a double-struck X that looks like a math symbol, picked within a few days.

The rest followed piece by piece over almost a year:

• tweets became posts and retweets became reposts during summer 2023;
• Twitter Blue was renamed X Premium in August 2023;
• the app changed its name on the App Store at the end of July 2023;
• twitter.com started redirecting permanently to x.com on May 17, 2024.

This video, posted when the change was announced, captures the mood of July 2023 and the super-app pitch:

Why did Musk pick the letter X?

Musk gave his own explanation on July 25, 2023, in a post that got quoted everywhere. The Twitter name, he wrote, made sense when it was just 140-character messages going back and forth, “like birds tweeting.” Now you can post almost anything, including several hours of video. He added that the platform would add comprehensive communications and the ability to conduct your entire financial world. In that picture, a tweeting bird has no place.

The WeChat model

One reference comes up again and again: WeChat, the Tencent app that most people in China use to chat, pay at restaurants, book a taxi or settle their bills. Musk once summed it up by saying that in China you kind of live on WeChat, and that it’s like Twitter plus PayPal plus a whole bunch of other things. Linda Yaccarino, CEO at the time, described X on announcement day as “centered in audio, video, messaging, payments/banking.”

An old fixation with one letter

The other reason is personal. In March 1999, Musk founded X.com, an online bank. It merged with Confinity the following year, and in 2001 the combined company took the name of its best-known product, PayPal. Musk has often said he regretted losing that name. In 2017 he bought the x.com domain back from PayPal and barely used it for six years. Meanwhile the letter spread across his world: SpaceX, the Tesla Model X, even the name of one of his sons, X Æ A-Xii.

My take: both reasons work together. The everything-app plan was a good excuse to drop a name that felt too narrow, and the letter X had been sitting in a drawer since 1999.

Where is the everything app in 2026?

Three years after the rename, the project is moving, but slowly and mostly in the United States. Here is what exists at the end of September 2026:

• X Money: the payment service, built with Visa, opened to all US Premium and Premium+ subscribers at the end of July 2026, with a debit card and payments between friends. Nothing has been announced for Europe.
• X Chat: a separate encrypted messaging app, launched in April 2026.
• Grok: xAI’s AI assistant, built into the app.

Ownership has also moved a lot. On March 28, 2025, xAI, Musk’s artificial intelligence company, bought X in an all-stock deal that valued the network at $33 billion. On February 2, 2026, SpaceX absorbed xAI, and X with it, in a merger valued at $1.25 trillion. SpaceX then went public on Nasdaq on June 12, 2026. We covered the first step in our article on xAI acquiring X.

At the top, Linda Yaccarino joined on June 5, 2023 and stepped down on July 9, 2025. For users in the UK, Europe or Australia, X is still mostly what it was: a network of posts, videos and live conversations. The VICE News clip posted on the day of the switch sums up the pitch at the time: a new name to make a big impression, with the product meant to catch up later.

Is the Twitter name really gone?

Not in everyday speech. Three years on, plenty of people still say “Twitter”, “tweet” and “tweeting”, journalists included.

The name also ended up in court. In December 2025, X Corp. sued the startup Operation Bluebird in federal court in Delaware. Co-founded by a former Twitter general counsel, the startup wanted to relaunch a network called Twitter.now. It argued that X had abandoned the brand when it publicly said “adieu” to Twitter. X answered that a rebrand is not an abandonment of trademark rights.

On September 4, 2026, Judge Colm F. Connolly issued a preliminary ruling: the startup cannot use the Twitter name. He also found that X had likely abandoned the word “Tweet” and the bird logo. The service has since been called Tweet.app. The case is not over, so things can still change.

What does it change for your account?

The rename did not delete a single follower or old tweet. Your account, your handle and your history stayed the same. A few habits are still worth adopting in 2026:

1. Update the app from the App Store or Google Play: it’s called X, with a black icon.
2. Replace old twitter.com links with x.com in your Instagram bio, your website or your email signature. The redirect works, but a clean link looks more trustworthy.
3. Use the new vocabulary if you make graphics or tutorials: post, repost, X Premium. Your audience sees those words in the app every day.
4. Check your privacy settings: the menus have moved since 2023 and some options now sit in different places.
5. Give your first posts a push if you’re reviving a dormant account. A post that starts with a few X likes stands a better chance of being shown in the For You feed.
6. Get your best content moving: on X, reposts still drive reach. A few X retweets on a strong post give it a second life.
