The Supreme Court is considering the constitutionality of a law that would ban TikTok for the 170 million people who use the app in the U.S. If the court upholds the law, as other courts have done, the ban will go into effect on Sunday, Jan. 19.

With five days left until the date by which TikTok is to be either sold or banned in the United States, millions of users are reckoning with what happens when one of the internet’s most important media platforms just up and disappears.

TikTok faces an imminent shutdown in the United States after Congress passed a law last year forcing its Chinses owner ByteDance to either sell the platform or close it by this Sunday.

If the TikTok ban does go through, who wins? Who loses? That’s what we wanted to explore in this week’s Stay Tuned. We spoke with influencers, content creators, small business owners and industry analysts to figure out what’s at stake and who stands to win in its absence.
