What happens if TikTok is banned?

TikTok will be banned in the US on 19 January – unless the Supreme Court accepts a last ditch legal bid from its Chinese owner, ByteDance, that to do so would be unconstitutional.

But even if the country’s highest judicial authority agrees with the lower courts – and Congress – that the platform is a threat to national security will that actually stop Americans using it?

Will there be ways to bypass the ban – or could president-elect Donald Trump find a way to stop a law he says he opposed to, even if the courts uphold it?

And whatever happens to TikTok, who stands to benefit from the uncertainty clouding its future?
