TikTok is considering making its app inaccessible to U.S. users as early as Sunday if the Supreme Court upholds a ban requiring it to sever ties with Chinese ownership, according to sources familiar with the matter. Signed into law by President Joe Biden in April, the legislation mandates TikTok’s divestment to a U.S. company or a complete shutdown.

TikTok has not finalized its response if the court rules against it, but plans include either going “dark” immediately or allowing limited functionality for existing users without updates. Noel Francisco, TikTok’s attorney, confirmed that a shutdown is likely if the company loses the case. This echoes the app’s 2020 ban in India, where access was cut off overnight, forcing users and advertisers to pivot to alternatives like Instagram Reels and YouTube Shorts.

As TikTok faces an uncertain future, creators and brands reliant on the platform are bracing for significant disruption. Some, like creative agency Saylor, have already ceased posting, citing concerns over security risks and the potential degradation of the app. Meanwhile, U.S. users have shown increased interest in RedNote, a Chinese short-form video app now topping the Apple App Store.

If the ban is enforced, TikTok’s absence will reshape the U.S. social media landscape, forcing creators, brands, and users to adapt quickly to alternative platforms.
