EU designates ChatGPT under the DSA’s strictest rules

The European Commission designated ChatGPT as a Very Large Online Search Engine, or VLOSE, under the European Union’s Digital Services Act. The same decision designates Reddit and Roblox as Very Large Online Platforms, but the new AI angle is that Brussels is treating ChatGPT as a large-scale search service with reinforced risk-management duties.

What happened

The primary source is an official European Commission post dated August 31, 2026. According to the Commission, ChatGPT, Reddit and Roblox declared that they reach at least 45 million average monthly users in the European Union, the threshold that triggers designation under the Digital Services Act. From notification, the services have four months, until January 2027, to comply with additional obligations.

For ChatGPT, the VLOSE designation is especially significant because it places OpenAI’s chatbot inside the DSA’s most supervised layer, not merely as a conversational app. The Verge and Euronews corroborated the designation and noted that the change requires OpenAI to prepare for stronger European requirements around evaluation, mitigation and transparency of systemic risks.

What is confirmed

The European Commission confirmed that ChatGPT was designated as a VLOSE and that Reddit and Roblox were designated as VLOPs. It is also confirmed that the decision is based on the 45-million average-monthly-user threshold in the EU, as declared by the services themselves. The Commission lists examples of reinforced obligations: assessing and mitigating risks stemming from the service and algorithmic systems, including illegal content, negative effects on minors, physical and mental well-being, fundamental rights, electoral processes and public security.

Reuters also reported the measure on August 31, according to the Google News RSS record. Direct Reuters access was blocked during this run, so substantive verification relied on the Commission’s official source plus readable pages from The Verge and Euronews.

Why it matters

The designation marks a regulatory turn for mass-market AI chatbots. In practice, Brussels is saying that a conversational assistant that answers, summarizes, recommends or directs information can have systemic effects comparable to search engines and large platforms when it reaches sufficient scale.

For OpenAI, this does not mean a penalty or a finding of non-compliance. It does mean a heavier compliance burden: risk analysis, mitigation measures, transparency toward regulators and readiness for audit or supervision under the DSA. For other AI companies, the signal is clear: user growth in Europe can move a product from useful tool to regulated information infrastructure.

What remains unclear

It remains to be seen how OpenAI will implement concrete changes for ChatGPT before January 2027, what the Commission will consider sufficient, and whether there will be disputes over the technical scope of treating ChatGPT as a search engine. It is also unclear how much the daily user experience will change.

The cautious reading is that this is a formal regulatory event, not an accusation of harm. It matters because it sets a new boundary: general-purpose AI systems that organize information will not be evaluated only as software products, but also as digital infrastructure actors with obligations around risk, transparency and public safety.
