TikTok is fighting for its life as it faces a US ban set to come in a little over a week. On Friday, it's arguing its case before the Supreme Court.

The company is challenging a law that compels its Chinese owner, ByteDance, to divest from the US version of TikTok by January 19 or be forced to shut it down. It lost its case in the District of Columbia Circuit in December and is now appealing to the Supreme Court for an emergency injunction to pause its divestment deadline.

During oral arguments on Friday, the company said it would be "extraordinarily difficult" for it to divest its US platform from the rest of TikTok globally over any timeline.

Without court intervention, after January 19, the company said, it would "go dark" as it would be pulled from app stores. Its service providers would also stop working with the company.

"It's essentially going to stop operating. I think that's the consequence of this law, which is why I think a short reprieve here would make all the sense in the world," TikTok's attorney Noel Francisco said.

The company's prospects of getting more time don't look great, legal analysts told Business Insider.

Like the DC Circuit, the Supreme Court is likely to show deference to Congress on questions of national security, even in instances where First Amendment rights are at stake.

"It's going to be an uphill battle," G.S. Hans, a clinical professor of law at Cornell Law School, told BI. "TikTok lost 3-0 in the DC Circuit. They lost with a cross-ideological panel."

He added: "If you're the company, you're hoping for a change of fortune. That's a tall order because of the general deference on natural security grounds to the political branches from the courts."

Matthew Schettenhelm, a litigation and policy analyst at Bloomberg Intelligence, described TikTok as an underdog in the case, estimating the company had a 30% chance of being rescued by the Supreme Court.

If TikTok fails to win more time through court intervention, its business partners, such as Apple, Google, and Oracle, will likely cut ties with the app in the US after January 19 to comply with the law. Apple and Google host TikTok in their app stores, while Oracle works with the social media site to store its US user data. None of the three companies responded to requests for comment.

Neama Rahmani, a former federal prosecutor in California, also told BI he expected the court to uphold the TikTok-ban law.

Rahmani said the court would likely find the TikTok ban consistent with other antitrust laws because it would force ByteDance to divest and find a new owner for the company instead of banning the app outright.

"We're not saying that TikTok isn't allowed; it just cannot be owned by a Chinese company where the Chinese government has access to this information," Rahmani said.

Still, he said one thing TikTok had going for it was that the Supreme Court decided to hear the case after the DC Circuit Court decisively upheld the law.

"Four justices agreed to hear this case and to fast-track it, so reading the tea leaves, that is somewhat good for them," Rahmani said.

Why is TikTok facing a ban?

TikTok was included in the Protecting Americans from Foreign Adversary Controlled Applications Act, passed in April. The act sought to limit the influence of social apps with ties to countries the US deemed foreign adversaries to guard national security interests. ByteDance is headquartered in China, which the US government has called a foreign adversary.

While members of both parties in Congress have raised alarm bells about TikTok, support for a ban among the American public has declined over the past couple of years. Support for a government ban fell from 50% in March 2023 to 32% in July and August among US adults who responded to Pew Research Center surveys.

Donald Trump may try to save TikTok as president, as he pledged to do during his campaign run. Trump filed an amicus brief on December 27 asking the Supreme Court to pause the deadline for a TikTok divestment so he could try to negotiate a political resolution once in office.
