BUZZ-Social media shares fall on US Supreme Court's ruling against TikTok

Shares of Instagram-owner Meta Platforms META.O and Snapchat-parent Snap SNAP.N fall between 0.4% and 3.3%

Supreme Court upheld law banning TikTok in U.S. on national security grounds if Chinese parent co ByteDance does not sell the short-video app by Sunday

Judges unanimously ruled that the law did not violate First Amendment

TikTok plans to shut its app for U.S. users from Sunday, sources familiar with the matter said on Wednesday

Ban on TikTok would push more users — nearly half of all Americans — and advertisers to Meta's Instagram, Facebook, Snapchat and YouTube, analysts say

If ban goes through, $11 bln of annual U.S. ad investment will be up for grabs, marketing group WARC Media says

Ban could be short-lived if ByteDance decides to sell or Trump manages to keep TikTok afloat, eMarketer says

Even if Trump chooses to delay or not enforce the ban, users, brands and creators may continue moving away from the app while its future remains in limbo, eMarketer adds
