AI-generated zero-click overviews are now the subject of a formal European Commission antitrust investigation, a significant escalation from where this dispute stood when it first became public. The Independent Publishers Alliance filed the original complaint in July 2025, accusing Google of misusing web content for its AI Overviews in a way that has caused significant harm to publishers through lost traffic, readership, and revenue. On 9 December 2025, the Commission confirmed it had opened a formal investigation into whether Google’s conduct breaches EU competition rules, a meaningfully higher bar than a complaint alone.

The complaint’s core argument has not changed since July, only its regulatory weight. Publishers cannot opt out of having their content used to generate AI Overviews and AI Mode responses without losing access to Google Search entirely, given the search engine’s roughly 90 percent market share in the EU. That structural bind, participate without compensation or disappear from the internet’s dominant discovery layer, is precisely what the Commission’s investigation will now formally test against EU competition law.

What the Commission Is Actually Investigating

The formal investigation covers two specific concerns. First, whether Google’s generation of AI Overviews and AI Mode responses draws on web publishers’ content without appropriate compensation, and without giving publishers a genuine ability to refuse that use without being removed from Search results altogether. Second, whether Google’s restrictions on how YouTube content can be used to train rival companies’ AI models, while presumably training Google’s own systems on the same content, constitute anticompetitive self-preferencing. Both questions sit within Article 102 of the Treaty on the Functioning of the European Union, which governs abuse of a dominant market position.

What This Means for Anyone Publishing Online in Europe

For publishers, especially smaller and regional outlets without the negotiating leverage of major news organisations, the practical stakes are existential rather than abstract. Foxglove, one of the organisations behind the original complaint, has warned that a formal investigation alone will not stop the harm while it proceeds, since EU antitrust investigations typically take months or years to conclude. The organisation has pushed for an interim injunction allowing publishers to opt out of AI Overview inclusion without losing standard search visibility, a remedy the investigation itself does not guarantee will be delivered before smaller publishers are forced out of the market entirely.

Google’s Defence, and Why It’s Genuinely Contested

Google’s position has been consistent throughout. A company spokesperson has called the complaint an attempt to stifle innovation in what it describes as a highly competitive market, arguing that AI features in Search create new opportunities for content and businesses to be discovered rather than simply displacing existing traffic. The company has also argued that publisher traffic changes are frequently driven by factors unrelated to AI Overviews. This is the same underlying dispute covered in our reporting on whether publishers can survive the zero-click era and the click-through data behind Google’s AI Mode UK launch, both sides agree individual result pages see fewer clicks when an AI summary appears, and disagree entirely about what that means once averaged across the whole of Google’s search volume.

The Bigger Pattern This Fits Into

This investigation does not stand alone. It follows a EUR 2.95 billion fine the Commission levied against Google in September 2025 for anticompetitive conduct in the advertising technology market, and it arrived alongside a separate EU antitrust investigation into Meta’s WhatsApp AI data-sharing policy the same week. The European Publishers Council has since filed its own formal complaint directly complementing the Commission’s investigation, warning that without intervention, smaller, regional, and specialist publishers will be the first pushed out of the market entirely, an outcome the Council argues undermines the Commission’s own stated commitment to media plurality and democratic resilience.

The tension underlying all of this, as our reporting on AI’s invisible infrastructure has explored in other contexts, is that the tools curating what content reaches an audience carry genuine editorial weight, whether or not they are marketed as neutral search results. A formal antitrust investigation does not resolve that tension on its own. It does, however, mark the first point at which the argument publishers have been making since 2024 has moved from grievance to a live, binding legal question the European Commission is now formally obligated to answer.
