Honestly with the way the Supreme Court is currently set up, there is a strong possibility that ByteDance will win if it is able to get that far. If they don't win, it will be a doozy to watch the Supreme Court go against nearly every large incorporated rights judgement of the last 30 years, especially from judges who 'supposedly' fully believe in those models of corporate rights
They can always say that 'actually it's not a problem due to national security, also this decision cannot be used as precedent'. It seems to be a pattern with the Supreme Court nowadays.
But who knows, maybe Capital isn't interested in this sort of government lead forced takeover. It's a Facebook plan after all.
This is the most likely outcome. They would be opening up a huge can of worms by siding against TikTok here, but they would have to, so the easiest way to do both is to just not hear it.
I think there's a pretty good chance they'd win as well. As I recall, TikTok also has US based investors which means you'd have US oligarchs with vested interest.
