The law, which was passed in April, aims to force ByteDance, the Chinese-owned parent company of TikTok, to sell the platform or face a ban.
The United States' Supreme Court said on Wednesday said it will hear arguments next month over the constitutionality of a federal law that could ban TikTok in the country if its Chinese-owned parent company doesn't sell it.
The justices will hear arguments January 10 about whether the law impermissibly restricts freedom of speech in violation of the First Amendment of the US Constitution.
The law, enacted by federal lawmakers in April, set a January 19 deadline for TikTok to be sold or else face a ban.
The popular social media platform has more than 170 million users in the US alone.
It's unclear how quickly the high court might issue a decision.
