Update: Supreme Court upholds law that could ban TikTok in the U.S. Read more. The start of the weekend marks two days until the social media platform TikTok could be banned in the United States. TikTok's Chinese parent company ByteDance has until Sunday to sell the platform under federal legislation signed into law by President Joe Biden last spring.

TikTok said it will have to “go dark” this weekend unless the outgoing Biden administration assures the company it won’t enforce a shutdown of the popular app after the Supreme Court on Friday unanimously upheld the federal law banning the app unless it’s sold by its China-based parent company.
