Summary

TikTok, with 170 million US users, faces a nationwide US ban starting January 19 unless its Chinese parent company, ByteDance, sells the platform.

A court rejected ByteDance’s bid to delay the ban, forcing TikTok to appeal to the Supreme Court.

The US government cites national security concerns over data collection, while TikTok argues its US user data is stored domestically.

President Biden may grant a 90-day extension, but the decision could fall to Trump, who has opposed banning TikTok.
