Meta Platforms , the social-media and AI giant, faced a fresh regulatory squeeze in Europe as the EU proposed putting far more responsibility for children's online safety directly on platforms. Meta shares traded at $672.84 Thursday. The GuruFocus chart also shows the stock 21.21% below its GF Value estimate of $853.92, suggesting investors are already pricing in a meaningful gap between Meta's market valuation and GuruFocus' estimate of fair value.

The proposed EU KIDS Act would block social-media access for children under 13 and require parental controls for users aged 13 to 15. Reuters reported that the proposal would also target profiling algorithms, infinite scrolling, reward-based engagement and unsolicited contact, while AI companions would be switched off by default for younger users. Platforms could face penalties of as much as 6% of worldwide annual sales for non-compliance, although the proposal still needs negotiations with EU member states and the European Parliament before becoming law.

That matters because Meta is pouring huge money into the infrastructure designed to make AI and recommendation systems more powerful. The company spent $31.08 billion on capital expenditures last quarter, equal to roughly 51.1% of revenue. Europe is now targeting some of the engagement mechanics sitting closest to that monetization engine. Meta does not separately disclose revenue generated from users under 18, so the real financial question is not simply how many young users could disappear. It is how much Meta may need to redesign recommendation, advertising and AI products across Europe before investors can quantify the revenue actually at risk.
