Elon Musk just passed the 100 million follower mark on Twitter, becoming the sixth user on the platform to reach a nine-digit follower count.

According to SocialBlade, Musk hit the milestone sometime between June 26th and June 27th, gaining over 150,000 followers between the two days. As of this writing, Musk now has 100,059,886 followers.

Hitting the milestone is interesting for a couple of reasons. First is the obvious fact that Musk is currently in the process of buying Twitter for $44 billion, which could eventually put him in the unique position of being the only leader of a major social media network who’s actually good at using their social media network. In contrast, Meta CEO Mark Zuckerberg’s Facebook page is broadly a feed of press releases, while Instagram head Adam Mosseri has a similarly saccharine presence on the platform he manages.
