TikTok eclipsed Twitter, Pinterest, and Snapchat in US users within just a few years, according to our estimates, and now it’s chasing Instagram. After years of exceptional growth, TikTok will boast more than 100 million US monthly users in 2023—unless lawmakers stand in its way.

Beyond the chart: This year, 45.3% of US social network users will use TikTok at least once a month, per our forecast. For comparison, 78.7% will be on Facebook as often. TikTok has room to grow, especially among older users. But it first has to convince US lawmakers that it’s safe to keep around.
