Elon Musk now has 100 million Twitter followers, a social media network that he may be poised to acquire.

It means he’s now followed by around 43 percent of individuals who use the microblogging site, but that figure might be far lower if, as Musk fears, many of those accounts are bots.

Despite the big number, Musk is only the sixth most-followed person on Twitter. The top five are as follows:

Barack Obama: 132.1 million
Justin Bieber: 114.1 million
Katy Perry: 108.8 million
Rihanna: 106.9 million
Cristiano Ronaldo: 101.3 million

Barack Obama’s account publishes frequently, but they’re as thoughtful and presidential as you’d expect, while Rihanna, Katy Perry, and Cristiano Ronaldo have Twitter presences that could only emerge from the collective brain of a highly trained communications staff. To his credit, I believe Justin Bieber manages his own account, but he hasn’t tweeted since February 16th.

Three years after the platform’s debut, in 2009, the CEO of Tesla and SpaceX joined Twitter. He has published around 18,500 tweets throughout that period on a wide range of topics. Additionally, several of those tweets landed him in hot water with the law.

Interestingly, Musk hasn’t tweeted anything since June 22, arguably one of his longest silences on the platform in recent years.

It’s unclear whether his silence had anything to do with his recent attempt to pay more than $44 billion to purchase the microblogging site. The transaction, which Musk suggested in April but hasn’t yet signed and finalized, encountered a snag earlier this month when a lawyer for Musk claimed that the billionaire entrepreneur would withdraw his bid unless Twitter provided information on the amount of bogus and spam accounts on the network.

The achievement of the record is intriguing for these few factors. The first is the obvious one: Musk is currently in the process of purchasing Twitter for $44 billion like just mentioned, which might one day place him in the rare position of being the only CEO of a significant social media network who actually knows how to use their network. Mark Zuckerberg, the CEO of Meta, posts news releases primarily on his Facebook page, while Adam Mosseri, the head of Instagram, has an equally cloying presence on the website he oversees.

Twitter, located in San Francisco, replied by providing a vast amount of data, but it’s still unclear whether this would be sufficient to keep the transaction on track as analysts will need to look through the data to try to determine the number of bogus and spam accounts on the service.

Although Twitter has long stated that fraudulent and spam accounts only account for roughly 5% of its user base, Musk is concerned that the actual percentage may be significantly higher. If so, advertisers would stop using the platform or demand reduced prices, and Musk would probably feel pressured to try to lessen the amount of his buyout bid or to withdraw completely.
