The app could theoretically continue to function in the short term, but service providers will be prohibited from working with TikTok.

TikTok will shut down entirely in the US on Sunday without intervention from the US Supreme Court, unnamed sources have told Reuters. That would go beyond the ban’s requirement for app stores to stop offering downloads of the app, but not immediately halt use of it.

TikTok is reportedly setting up a plan to shut down in the U.S. as the Supreme Court continues to weigh Sunday's looming ban.
