TikTok transformed everyday users into influencers and made entrepreneurs rich via its Shop feature. With the US ban looming, they could lose everything—and many don’t know where to go next.

If the Supreme Court votes to uphold the law that President Joe Biden signed in April, TikTok will shut down on January 19th, the day before Donald Trump takes office. The popular social media platform is used by hundreds of millions of people, including well over a hundred million in the U.S.

The court heard oral arguments on TikTok’s bid to block a law that would lead to its ban in the U.S. starting Jan. 19 if it isn’t sold by its Chinese owner.

Congress labeled the app’s Chinese ownership a national security risk and passed a law that would ban the social media platform unless it was sold. TikTok and creators say that violates their free speech rights.

The law that could ban TikTok is coming before the Supreme Court. The justices largely hold the app’s fate in their hands as they hear the case Friday.
