EU Classifies ChatGPT as a Search Engine and Reddit and Roblox as Large Platforms

The European Commission has placed ChatGPT, Reddit and Roblox under the Digital Services Act’s strictest tier of oversight. The announcement published on August 31, 2026 says all three services declared at least 45 million average monthly users in the European Union, the threshold that triggers additional obligations for the largest digital intermediaries.

The decision does not, however, put all three products in the same category. ChatGPT was designated a Very Large Online Search Engine, while Reddit and Roblox were designated Very Large Online Platforms. That distinction is the announcement’s most revealing detail: for the European regulator, a conversational interface can perform a search function without resembling a conventional page of ranked links.

Why ChatGPT’s category matters

The designation does not claim that ChatGPT is identical to Google, nor does it decide that every generated answer is equivalent to a traditional search result. It establishes which additional supervisory regime applies under the DSA. The classification moves the debate away from the product’s commercial identity and toward the role it plays when people seek information, receive summaries and make decisions based on them.

The framework also avoids treating every popular service as a social network. Reddit organizes community-produced content distributed through recommendation systems. Roblox combines creation, discovery and interaction inside a platform of experiences. ChatGPT provides answers through a generative system. Reuters confirmed the difference between the categories in its report on the decision, even though all three services now enter the same expanded tier of responsibility.

The companies have four months, until January 2027, to meet the additional requirements. According to the Commission, those duties include assessing and mitigating systemic risks involving illegal content, negative effects on minors, physical and mental well-being, fundamental rights, electoral processes and public security. Designation begins this compliance phase; it is not a finding that any of the services has already violated the regulation.

The risks are not identical across the three services

The risk list is shared, but its application will depend on how each product works. For Reddit, oversight may examine how communities, moderation and recommendations shape the circulation of content. For Roblox, its large population of younger users makes child protection and interaction design especially relevant. For ChatGPT, a central question is likely to be how answers, search mechanisms and recommendation systems amplify or reduce risks involving information and rights. These are likely consequences of the framework, not findings of misconduct.

The Commission’s official page for VLOPs and VLOSEs lists obligations that include maintaining an internal compliance function, undergoing an annual independent audit, sharing data with authorities, giving vetted researchers access to data relevant to systemic risks and offering a recommendation option that is not based on profiling. It also requires greater advertising transparency where applicable.

In practice, compliance will require more than publishing terms of service. The companies will need to show how they identify risks, what measures they adopt, how they measure outcomes and why their systems make particular choices. Governance, engineering, safety, moderation and documentation consequently move closer together: decisions once treated as internal product details must now produce evidence that can be audited.

What may change for users and developers

European users may eventually see new recommendation controls, clearer explanations, reporting channels and safeguards for minors. The announcement does not yet contain a specific list of changes promised by the three companies, and it does not order the removal of particular answers, forums or experiences. Its immediate effect is regulatory: the Commission gains investigative powers over the functions and related systems of the designated services.

For developers and product teams, the decision strengthens a trend Rota42 previously examined through California’s transparency rules for AI-generated content: digital compliance is moving beyond legal text and becoming verifiable infrastructure. The difference is scope. The DSA addresses systemic risks across an entire service, while the California measure discussed there focused on provenance and the identification of media.

ChatGPT’s designation as a search engine therefore matters more than a change of label. It signals that widely used generative products can be assessed according to the role they occupy in access to information. Reddit and Roblox arrive at the same oversight tier through different paths. By January 2027, the decisive question will be how each company translates shared obligations into measures suited to its own architecture and audience.
