Meta's ad revenue stalls as EU rules and US lawsuits bite

Meta’s ad revenue slowed this quarter, and the dip lines up with two regulatory fronts tightening around the company.

In the earnings briefing on Wednesday, Meta disclosed that revenue from its advertising business has decelerated since the European Union rolled out its Less‑Personalized Ads model at the start of the year (WIRED). The same week, a New Mexico court slapped the firm with a $25 billion fine—the largest ever levied against Mark Zuckerberg—and announced that Meta will appeal (Ars Technica). Adding to the pressure, Rhode Island filed the first state lawsuit accusing Meta of facilitating scam ads on its platforms (Engadget). Together, these events illustrate a growing friction between the tech giant’s ad engine and regulators on both sides of the Atlantic.

EU’s Less‑Personalized Ads model hits the bottom line

The EU’s new framework forces Meta to replace granular user profiling with broader audience buckets. Under the rule, advertisers can no longer rely on detailed behavioral signals to match ads to individual users. Meta’s ad platform, built on billions of data points, loses a key lever for price discrimination and conversion optimization.

When Meta reported the slowdown, it did not break out the exact percentage, but the timing is clear: the revenue curve flattened shortly after the model’s January launch (WIRED). The company’s statement framed the dip as a short‑term adjustment, but the data suggests a structural shift. Advertisers who depend on precision targeting now face higher CPMs for the same reach, and some have shifted spend to platforms with fewer restrictions.

New Mexico fine marks a new escalation in US enforcement

A state court in New Mexico issued a $25 billion penalty after Meta refused to join a multistate settlement aimed at curbing the firm’s alleged anticompetitive practices (Ars Technica). The ruling represents the single largest financial hit in Zuckerberg’s career and signals that state prosecutors are willing to go beyond the federal antitrust playbook.

Meta announced its intent to appeal, arguing that the fine exceeds any reasonable calculation of damages (Ars Technica). The appeal will likely drag into 2025, giving the company a window to negotiate settlements elsewhere. Still, the sheer size of the judgment sends a warning to other tech firms that state‑level actions can carry the weight of a federal case.

Rhode Island takes on scam ads, a first for a state

In a separate legal front, Rhode Island sued Meta over the platform’s handling of scam advertisements (Engadget). The suit claims Meta’s ad review processes are insufficient to block fraudulent offers that prey on consumers. The complaint is the first of its kind to target a state’s specific grievance against the social‑media giant’s ad ecosystem.

The state’s attorneys argue that Meta’s algorithms prioritize engagement over safety, allowing scam ads to slip through. While the lawsuit does not disclose the monetary damages sought, it puts pressure on Meta to tighten its ad‑screening tools or face further litigation in other jurisdictions.

The broader ad‑tech regulatory storm

Meta’s challenges are not isolated incidents; they sit at the intersection of a global push to rein in data‑driven advertising. Europe’s GDPR set the stage for stricter consent regimes, and the Less‑Personalized Ads model is the latest iteration aimed at limiting profiling. In the United States, the rise of state‑level antitrust and consumer‑protection actions shows a fragmented but increasingly aggressive approach.

Historically, Meta has relied on a “walled garden” model where user data fuels a high‑margin ad business. The EU rule forces a pivot to contextual targeting, which historically yields lower click‑through rates. Meanwhile, the $25 billion fine underscores that the U.S. legal environment is no longer content to let the company self‑regulate. Together, these pressures could reshape the economics of social‑media advertising, pushing Meta to diversify revenue streams or invest heavily in compliance infrastructure.

What to watch next

The next earnings call will reveal whether Meta can stabilize ad revenue without the granular data it once wielded. Courts in New Mexico and Rhode Island will issue rulings on the fine and the scam‑ad lawsuit, respectively, within the next six months. Finally, the European Commission is expected to publish guidance on how the Less‑Personalized Ads model should be implemented, a document that could tighten or relax the current constraints. Tracking these decisions will show whether Meta can adapt its ad engine or whether the regulatory tide will force a more fundamental redesign of its business model.
