X now has 600 million monthly active users (MAU) globally.

"X is group chat for Earth," Musk posted.

One user commented that "X is a global town square for people".

Another posted, "New X feature inbound... Earth Chat."

The tech billionaire, who acquired X (then called Twitter) for $44 billion in 2022, aims to make it an "everything app" where people can post movies and TV shows and even make digital payments .

Musk also claimed that X usage in the US has reached an all-time high.

"Total user-seconds in the US are nearly 76 billion, beating the previous record by 5 percent," the X boss announced.

In March, X reported that users were spending an average of 30 minutes per day on the platform.

When Twitter was acquired by Musk in October 2022, it was originally a 140-character messaging app.

At the time of its $44 billion acquisition, there were approximately 3,500 creators on the platform.
