The decision came a week after the justices heard a First Amendment challenge to a law aimed at the wildly popular short-form video platform used by 170 million Americans that the government fears could be influenced by China.

The Supreme Court has unanimously upheld the federal law banning TikTok beginning Sunday unless it’s sold by its China-based parent company.

Say goodbye to your favorite app. After hearing arguments from the Department of Justice, ByteDance, and TikTok users last Friday, the Supreme Court says it will uphold the nationwide TikTok ban slated for January 19.

The Supreme Court unanimously found the new law that could lead to a ban of TikTok does not violate the First Amendment rights of the platform or its users.

Now that TikTok has finally reached the end of its legal options in the US to avoid a ban, somehow, its future seems less clear than ever. The Supreme Court couldn’t have been more direct: the Protecting Americans from Foreign Adversary Controlled Applications Act,

ByteDance has so far rebuffed the idea of selling TikTok. But the lawyer for the US government told the Supreme Court that a ban might be just the “jolt” needed to persuade it to consider the idea, noting that restrictions could be lifted once a deal materialises.

After hearing arguments on Friday morning, the U.S. Supreme Court decided to uphold the law, meaning that TikTok will be banned effective if the parent company ByteDance does not sell the company by Sunday.

With the ban upheld by the Supreme Court and the Biden administration leaving, TikTok CEO Shou Zi Chew is banking on Trump to save the app in the US.

As TikTok’s fate hangs in the balance, roughly 170 million users across the United States face the possibility of losing access to the app, which has become the focal point of a growing national security debate.

A TikTok ban Sunday would implicate tech giants like Google, Apple and Oracle, who risk enormous fines if they keep the app operational.

There are “no plans” for a TikTok ban in the UK, officials have said as a block in the US is set to come into force on Sunday.
