The BBCTikTok said it will be forced to “go dark” in the US on Sunday unless the government intervenes before the federal ban takes effect.
It said in a statement that “both the Biden White House and the Department of Justice have failed to provide the necessary clarity and assurance to service providers that are integral to maintaining TikTok's availability.”
It added that unless the US government provides an immediate statement providing assurances of non-enforcement, “TikTok will unfortunately be forced to shut down on January 19.”
TikTok's statement follows a Supreme Court ruling earlier on Friday that upheld a law that would ban the video app in the US unless China-based parent company ByteDance sells the platform by Sunday.
TikTok challenged the law, arguing that it would violate free speech protections for its millions of users in the country.
The Supreme Court ruling means the US version of the app will be removed from app stores and web hosting services unless a buyer is found for the company by Sunday.
It was believed that the ban would not affect TikTok users who already have the app downloaded on their phones.
But a new statement from TikTok on Friday suggested that it could immediately become unavailable to all 170 million users in the US, as well as those who want to download it on Sunday.
