The European Commission just told Meta what parents have been saying for years: your platforms are designed to keep kids glued to their screens. And now there’s a regulatory price tag attached.

On June 23, the Commission released preliminary findings accusing Meta of deploying design practices across Facebook and Instagram that effectively make the platforms addictive, with children bearing the brunt of the harm. The investigation, conducted under the EU’s Digital Services Act, found that Meta has failed to adequately prevent users under 13 from accessing its services, with an estimated 10-12% of EU children in that age group reportedly active on the platforms.

What the EU actually found

The Commission issued similar concerns back in April 2026, flagging Meta’s age verification gaps and the addictive nature of its platform design. Formal proceedings against the company actually began in 2024, making this a multi-year effort to force one of the world’s largest social media companies to take child safety seriously.

The core accusation is straightforward. Meta’s platforms are built around engagement mechanics that can trigger behavioral addictions in minors. Think infinite scrolling, algorithmic content feeds that learn exactly what keeps a teenager watching for “just five more minutes,” and notification systems engineered to pull users back.

The Commission issued preliminary findings against TikTok in early February 2026 for strikingly similar practices, including infinite scroll and autoplay functions. Confirmed breaches of the DSA could result in fines of up to 6% of Meta’s total annual worldwide turnover.

The regulatory playbook taking shape

The DSA classifies Meta’s platforms as Very Large Online Platforms, or VLOPs, a designation that comes with heightened obligations around risk assessment, transparency, and user protection.

Meta’s defense has historically centered on its existing safety tools, parental controls, and age-gating mechanisms. But the Commission’s findings suggest those measures aren’t cutting it. When roughly one in ten EU children under 13 is using platforms that officially require users to be at least 13, the age verification system is less of a wall and more of a suggestion.

The UK’s Online Safety Act covers similar ground. Australia passed legislation banning social media for children under 16. US states have been passing their own patchwork of child safety laws.

By pursuing both Meta and TikTok on nearly identical grounds within months of each other, the Commission is signaling that this isn’t about targeting a single company. It’s about rewriting the rules for an entire industry.

What this means for investors

If the Commission confirms its findings and imposes penalties at or near the 6% threshold, the financial hit would be substantial. But the fine itself might not be the biggest concern. If Meta has to fundamentally alter how its algorithms serve content to younger users, or implement age verification systems rigorous enough to actually work, that affects the engagement metrics that drive advertising revenue. Less time on platform means fewer ads served means lower revenue per user.
