Meta Bans TikTok Ads in the US and Six Other Countries – A Rivalry Turns Into a Blockade

.

What Meta Did

Meta began enforcing a complete ban on ads and paid promotions from ByteDance on Thursday. A Meta spokesperson said the company has no obligation to sell ad space to a competitor whose goal is to pull users away from its apps. He described refusing such business as "a normal business practice across industries."

The ban applies at once in seven countries. Third-party advertisers are included, so a small business can no longer run an Instagram ad that sends people to a TikTok page.

At the time of reporting, neither TikTok nor ByteDance had publicly responded.

A Feud That Was Already Heating Up

The two companies have competed for years over users, creators and advertising money. Bloomberg points to an imbalance in the rivalry: TikTok can operate in Meta's most important market, the United States, while Meta cannot operate in TikTok's most important market, China.

The conflict sharpened in August, when Meta agreed to a settlement of up to $18 billion with US states over harm to children from social media. Meta committed to daily usage limits, restrictions on nighttime use by minors, and stronger barriers to age-restricted content.

Since then, Meta has pushed TikTok and YouTube to adopt similar rules. It argues that it cannot solve the industry's child-safety problems alone. Meta also took out newspaper ads and publicly criticized TikTok for skipping a Surgeon General event on excessive screen use. It also said TikTok pulled out of a meeting with the House Select Committee on China.

TikTok pushed back last month. According to Bloomberg, it rejected Meta's ads demanding the same child-safety commitments. Axios reported that TikTok classed them as political content, which its rules do not allow. TikTok also removed dedicated Instagram links from user profiles.

TikTok has its own legal pressure on child safety. In September it settled with Alabama, agreeing to new usage limits and stronger age checks.

Who Actually Runs TikTok in America?

The ban lands on a company whose ownership is still debated. Under the deal arranged during the Trump administration, a US joint venture led by Oracle, Silver Lake and Abu Dhabi's MGX holds 80.1 percent. ByteDance keeps 19.9 percent. Oracle acts as the security partner, and US user data is stored on Oracle's cloud in the United States.

Reuters describes TikTok as a majority American-owned joint venture. Bloomberg, however, says ByteDance "remains in charge of key parts" of TikTok in the US.

The doubt centers on the recommendation algorithm, the code that decides which videos users see. US officials have long warned that Chinese authorities could use it to shape what Americans watch. The House Select Committee on China has said there can be no shared algorithm with ByteDance. Analysts also say it remains unclear whether the algorithm was transferred, licensed, or is still under ByteDance's control.

What Comes Next

Meta's move mainly hurts ByteDance's other products and its advertising reach. For TikTok's US venture, the practical effect depends on how Meta applies the rule to campaigns tied to the TikTok app.

Three things are worth watching: whether TikTok or ByteDance respond, whether YouTube comes under similar pressure, and whether Congress takes a fresh look at ByteDance's role in TikTok's US operations. Bloomberg notes that platforms are increasingly putting up walls against rivals. It cites a report that OpenAI told advertising partners it will not accept ads for competing image and audio-generation tools.
