Is Banning TikTok Constitutional? The First Amendment Ruling

Yes. On January 17, 2025, the Supreme Court ruled that banning TikTok is constitutional. In a unanimous per curiam opinion in TikTok Inc. v. Garland, the Court upheld the Protecting Americans from Foreign Adversary Controlled Applications Act, finding that the law satisfies the First Amendment because it serves an important government interest in national security and does not burden substantially more speech than necessary.¹

What Congress Actually Passed

The law, enacted in 2024, makes it illegal to distribute, maintain, or update a “foreign adversary controlled application” in the United States unless the app undergoes a qualifying sale that severs foreign adversary control. It names ByteDance and TikTok directly, along with subsidiaries and successors under foreign adversary control.²

TikTok had 270 days from enactment to complete a “qualified divestiture.” That clock expired on January 19, 2025. To qualify, a sale must eliminate foreign adversary control and cut off any operational relationship between the U.S. platform and formerly affiliated foreign entities, including cooperation on the recommendation algorithm or data sharing.¹

So the law does not ban TikTok outright. It bans TikTok under its current ownership. That distinction turned out to matter.

Why the First Amendment Did Not Block the Ban

TikTok argued that shutting down a platform used by roughly 170 million Americans was a massive restriction on speech, silencing creators, businesses, and commentators and denying users the right to receive information. The Court agreed the First Amendment was in play. It just did not agree the law failed.

The Court Applied Intermediate Scrutiny

The level of scrutiny drove the outcome. Laws that restrict speech based on its content face strict scrutiny, the most demanding standard in constitutional law, which requires the government to prove it used the least restrictive means available. TikTok pushed for that standard. The Court declined.

Instead, the Court held the law is facially content-neutral. The statute does not target any message, topic, or viewpoint on TikTok. It targets who controls the platform and, by extension, who can access American user data. The government’s justification was “content agnostic,” the Court wrote: preventing a foreign adversary from harvesting personal information, not policing what anyone says on the app.¹

Content-neutral laws get intermediate scrutiny. Under that standard, the government must show the law furthers an important interest unrelated to suppressing expression and does not burden substantially more speech than necessary. It does not have to prove it picked the least restrictive option. That gave Congress far more room than strict scrutiny would have.

The National Security Interest Was Important Enough

ByteDance is headquartered in China, which Congress and the executive branch have designated a foreign adversary. Chinese law can compel domestic companies to turn over data to the government. TikTok collects extensive information from its users. The Court accepted the government’s concern that China could use this access to track federal employees, build dossiers for blackmail, or conduct corporate espionage.¹

The Court said it owed “substantial deference to the predictive judgments of Congress” on content-neutral national security legislation. Preventing a foreign adversary from harvesting data on tens of millions of Americans qualified as important. The risk, given Chinese law’s compulsion powers, was concrete rather than speculative.

The Law Was Not Substantially Overbroad

On tailoring, the Court found the law fit the problem. TikTok cannot operate without collecting user data, and that data stays accessible to ByteDance as long as ByteDance controls the platform. A divestiture requirement addresses exactly that mechanism by severing foreign adversary control before the platform can keep operating. The ban applies only if no qualifying sale happens.¹

The Limits the Concurrences Flagged

The judgment was unanimous, but two justices wrote separately to mark the ruling’s edges.

Congress and the executive branch had also raised a second worry: that China could manipulate TikTok’s recommendation algorithm to shape what Americans see, spreading propaganda or sowing division. The Court pointedly declined to rely on this content-manipulation rationale. Justice Gorsuch’s concurrence praised that restraint, warning that letting the government regulate platforms based on fears about what content a foreign owner might promote would open a dangerous door. He also flagged “serious reservations” about whether the law is truly content-neutral given how the government had argued the case.¹

Justice Sotomayor agreed the First Amendment was squarely implicated, not merely assumed to be, but joined the judgment because the law survived review regardless. Both opinions signal that a future statute more transparently aimed at controlling what appears on a foreign-owned platform, rather than who controls the data behind it, could face a very different reception.

The Other Constitutional Claims

TikTok raised two additional constitutional arguments beyond the First Amendment. The Supreme Court’s per curiam opinion did not engage with either at length, so the outcome on both traces to the D.C. Circuit’s reasoning.

The first was a bill of attainder claim. The Constitution prohibits Congress from passing laws that single out specific individuals or entities for punishment without judicial proceedings, and the law names ByteDance and TikTok directly.³ The D.C. Circuit rejected the claim, finding the law serves a nonpunitive, regulatory purpose tied to national security rather than legislative punishment.

The second was a Fifth Amendment takings claim, arguing that forcing a sale under threat of a ban deprives ByteDance of the full economic value of its U.S. operations.⁴ The D.C. Circuit found the law is a regulatory measure, not a taking, because it gives ByteDance the option to sell rather than seizing property.

Why TikTok Is Still on American Phones

The enforcement deadline hit on January 19, 2025, two days after the ruling. TikTok went dark in the United States that night for roughly 12 hours, with service providers pulling back rather than risk the penalties Congress had authorized. The app displayed a message telling users it was unavailable and directing them to “stay tuned.”

Service came back on January 20 after President Trump, taking office that day, pledged that no company would face penalties for continuing to support the platform. Trump then signed an executive order directing the Department of Justice not to enforce the law while his administration pursued a deal. That enforcement pause was extended by executive order in April, June, and September 2025, pushing the non-enforcement window to December 16, 2025.⁵

In late December 2025, TikTok signed a deal to create a new U.S.-based joint venture. Oracle, the private equity firm Silver Lake, and the Emirati investment firm MGX each hold a 15% stake as managing investors, with ByteDance retaining a 19.9% share and other investors holding the remainder. The deal closed in January 2026. American users continued using the app under the new ownership structure.

The law itself remains constitutional, and it remains on the books. It also reaches beyond TikTok: any social media platform with more than one million monthly active users that is controlled by a designated foreign adversary can be subject to the same divestiture requirement if the President identifies it as a national security threat, issues a public notice, and submits a report to Congress.² The framework the Supreme Court blessed in TikTok v. Garland is now the template for any future fight over a foreign-adversary-linked app.
