The company says it plans to go dark after the Supreme Court upheld a sell-or-ban law, but Trump says he will likely intervene.

Political shifts and legal hurdles have delayed TikTok's removal, with Biden reportedly kicking the issue to Trump.

The app had more than 170 million monthly users in the U.S. The black-out is the result of a law forcing the service offline unless it sheds its ties to ByteDance, its China-based parent company.

The Supreme Court has decided to uphold the law that will ban TikTok on Jan. 19 if its parent company ByteDance continues to refuse to sell the app before then.

TikTok is set to be banned in the US on 19 January after the Supreme Court denied a last ditch legal bid from its Chinese owner, ByteDance. It found the law banning the social media platform did not violate the first amendment rights of TikTok and its 170 million users, as the companies argued.

While TikTok remains hugely popular in Brazil, Indonesia and other markets, its 170 million users in the United States are its most valuable.

TikTok, owned by ByteDance, is on the verge of being banned in the United States. The thing is, the government could go after other ByteDance apps, and there are quite a few of them operating in the U.

The Supreme Court seemed to lean Thursday toward upholding a law forcing Chinese parent company ByteDance to sell off TikTok, with all nine justices indicating national security concerns posed by the social media app outweighed potential threats to free speech.

TikTok, the Chinese tech company, ByteDance-owned social media platform is no longer available in the United States. The application and the company that runs it have warned its users in the country that the application may no longer be available from Sunday after the US Congress passed legislation banning the application.

TikTok's parent company is asking the Supreme Court to halt a law that would require the company to sell TikTok to a U.S. firm or face a ban.

The ruling against TikTok disrupts the American social media landscape, impacting 170 million users who call it home.

The Supreme Court issued its opinion on the looming ban of TikTok in America upholding that the law will stay in effect, essentially forcing the app’s Chinese owner to sell its American holdings by Sunday or be forced to go dark.
