Late on Friday, however, TikTok said its US services would “go dark” unless the Biden administration “immediately provides a definitive statement to satisfy the most critical service providers assuring non-enforcement” of the law calling for the platform’s ban.
The administration of outgoing President Joe Biden, who leaves office on Monday, has said it will leave the matter to Trump’s incoming government.
After the court defeat, TikTok CEO Chew Shou Zi appealed to Trump, thanking him for his “commitment to work with us to find a solution.”
Trump “truly understands our platform”, he added.
TikTok has been lobbying furiously to thwart the law’s implementation, with Chew set to attend Trump’s inauguration on Monday.
The law requires Apple and Google to remove TikTok from their app stores, blocking new downloads. The companies could face penalties of up to US$5,000 per user who can access the app.
Oracle, which hosts TikTok’s servers, would also be under legal obligation to enforce the ban.
None of the companies responded to requests for comment.
OFFERS FOR TIKTOK
The law allows a 90-day delay if the White House can show progress toward a viable deal, but TikTok owner ByteDance has flatly refused any sale.
Frank McCourt, the former Los Angeles Dodgers owner, has made an offer to purchase TikTok’s US activity and said he’s “ready to work with the company and President Trump to complete a deal”.
Canadian investor Kevin O’Leary, who is involved in that offer, told Fox News that ByteDance was offered US$20 billion for TikTok’s US operation.
He acknowledged the legal uncertainty over the case, with it remaining an open question whether an executive order by Trump to halt the ban would override the law.
“Congress wrote this law to be virtually president-proof,” warned Adam Kovacevich, chief executive of industry trade group Chamber of Progress.
Sarah Kreps, professor of government and law at Cornell University, said: “If an executive order conflicts with an existing law, the law takes precedence, and the order can be struck down by the courts.”
If TikTok is forced into a shutdown, its US-based rivals Instagram Reels and YouTube Shorts would benefit.
Thousands of worried TikTok users have protectively turned to Xiaohongshu (“Little Red Book”), a Chinese social media network similar to Instagram.
Nicknamed “Red Note” by its American users, it was the most downloaded app on the US Apple Store this week.
