TikTok will have 834.3 million monthly users worldwide in 2023, according to Insider Intelligence’s forecast. It is now the third-largest of the Big Five worldwide social networks (Facebook, Instagram, TikTok, Snapchat, and Twitter). 

TikTok’s ascent to global phenomenon has been incredibly quick. It more than doubled its worldwide user base between 2019 and 2021 (291.4 million to 655.9 million). By 2025, it will approach 1 billion users.

Our estimates are significantly lower than the 1 billion users TikTok said it had as of September 2021 because of our forecast methodology. We factor out business and other nonhuman accounts, as well as spam and duplicate accounts. We also only include users who are logged in to the app (as opposed to those who view TikTok content outside of the platform or without being logged in to their accounts).
