TikTok is eating into ad growth for Snapchat, Instagram and more

Social media platform TikTok has taken the world by storm in recent years.
The Numbers: TikTok has popularized the short-form video content format and generates more than 90 minutes of engagement per active user, well above the engagement levels of other social media platforms.
The Losers: On the financial side, TikTok is expected to grow its advertising revenue by more than 170% this year to more than $12 billion. Post estimates ad revenue growth will create a 2.1% ad revenue growth headwind for TikTok's primary U.S.competitors this year, a significant growth hurdle for $Snap Inc(SNAP.US)$ , $Meta Platforms(FB.US)$ and $Alphabet-A(GOOGL.US)$ $Alphabet-C(GOOG.US)$
Post said Facebook, $Pinterest(PINS.US)$ and even streaming companies like $Netflix(NFLX.US)$ could feel the impact of TikTok's growth, but its user base and advertising dollars overlap most significantly with Snapchat, Meta's Instagram and Alphabet's YouTube.
There are only so many hours in the day, so every minute TikTok users are spending on the platform is a minute they are not spending on competing platforms. Unfortunately for U.S. investors, TikTok's Chinese parent company ByteDance is a private company, making it impossible for U.S. investors to buy shares.
