EU's 'very large search engine' label poses new compliance hurdles for ChatGPT

OpenAI's ChatGPT has crossed a critical regulatory threshold in the European Union, with authorities designating the AI chatbot as a 'very large search engine' under the bloc's stringent Digital Services Act (DSA). The classification comes after ChatGPT reported surpassing 45 million average monthly active users across EU member states, the metric that triggers the designation under the regulation.

The 'very large search engine' tag places ChatGPT in the same category as major internet platforms and carries significant compliance obligations. Under the DSA framework, entities meeting this threshold must implement enhanced content moderation, provide greater transparency to users about their algorithmic operations, and submit to regular EU audits. The designation also mandates more detailed reporting on how the service handles illegal content and misinformation.

This regulatory move reflects the EU's broader approach to governing artificial intelligence and digital platforms. The bloc has positioned itself as a global leader in tech regulation through the DSA and the recently enacted AI Act, imposing requirements that often exceed standards in other jurisdictions. For ChatGPT and other AI platforms, compliance means substantial investments in content monitoring systems, algorithm transparency, and regular interaction with EU regulators.

The reclassification could influence how OpenAI deploys new features and manages user data across Europe. Companies typically must adjust their operations within months of receiving such designations, potentially affecting service quality, feature rollouts, and operational costs. The move also sets precedent for how the EU will treat other large-scale AI applications as they expand their user bases in the region.
