The law—which prohibits U.S. app stores from hosting TikTok unless Chinese parent company ByteDance divests from it—is scheduled to take effect one day before Trump’s Jan. 2

The inbound Trump administration insists that TikTok will avoid a ban, but the long-term prospects of the social media app staying alive hinge on there being a deal for divestiture to a US company.
