January 17, 20253 min readSupreme Court Upholds Law Banning TikTok in U.S. Whats Next?The end seems nigh for TikTok in the U.S.By Ben Guarino edited by Dean VisserA TikTok influencer holds a sign that reads "Keep TikTok" outside the U.S. Supreme Court Building as the court hears oral arguments on whether to overturn or delay a law that could lead to a ban of TikTok in the U.S., on January 10, 2025 in Washington, D.C. Kayla Bartkowski/Getty ImagesOn Friday the Supreme Court affirmed that it would be legal to force TikTok owner ByteDance to sell the immensely popular app to a non-China-based company or to ban it in the U.S. Last week an attorney for TikTok had argued before the Supreme Court that a bipartisan law that mandated the sale or ban infringed on the companys First Amendment rights. The Court disagreed. In an unsigned opinion, the justices wrote that the U.S. governments security concernscountering Chinas data collection and covert content manipulation effortswere compelling and that the law was narrowly tailored to further those interests.As a result, TikTokwhich about 170 million Americans use to watch short-form videos and shopis likely to close in the U.S. as soon as next Sunday. (TikTok didnt immediately respond to a request for comment from Scientific American.) TikToks attorney told the Supreme Court last week that when the law goes into effect on January 19, the app will go dark.Whats Going to Happen to TikTok?On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

Although the law does not make it illegal for people in the U.S. to have TikTok on their phones, it fines app stores, such as Apples or Googles, whenever people download or update TikTok. Because the fines are up to $5,000 per user (which, multiplied by millions, would add up extremely quickly), app stores are expected to remove TikTok next Sunday. If users cannot update TikTok, the app will eventually stop working anyway.What Might U.S. TikTokers Do?Hundreds of thousands of U.S. TikTokers have joined other apps. These have included a newly popular China-based app named RedNote.Additionally, there are potential work-arounds for the U.S. bannamely, virtual private networks, or VPNs. In India, which banned TikTok in 2020, users have accessed the blocked app via these networks; they can make traffic appear as though its coming from a country where TikTok is allowed. This is not necessarily an easy solution, though. People in the U.S. may need a foreign billing address to access TikTok, one popular VPN service has pointed out, and their other apps or subscriptions could stop working.Will Elon Musk buy TikTok? Will enforcement of the law be delayed? And can incoming president Donald Trump halt the banas he asked the Supreme Court to doto negotiate a deal?TikTok says the answer to the first question is pure fiction. (Meanwhile YouTuber James Donaldson, aka MrBeast, joked/mused this week about whether he should purchase the app.) TikToks consistent public stance has been that it is not for sale. A few Democratic members of Congress introduced a bill this week to extend the TikTok ban deadline by 270 days, but Republican senators squashed that.As for that last question, when asked if he would take measures to reverse the ban, Trump told CNN that hell be making the decision. Trump is reportedly considering an executive order that would delay enforcement of the ban for 60 to 90 days, according to the Washington Post. But because presidents do not have the authority to overrule a law via executive order, how he might do so remains to be seen. That said, given Trumps history, it is difficult to predict what will happen after he takes office next Monday.Editors Note: As the Supreme Court has upheld the U.S. TikTok ban, many organizations that have been active on the platform, including Scientific American, are adapting to this shift.
