EU Classifies ChatGPT as a “Very Large Online Search Engine” Under the DSA

The EU has classified ChatGPT as a Very Large Online Search Engine under the DSA, bringing OpenAI under stricter rules on risk, transparency and oversight.

EU Classifies ChatGPT as a “Very Large Online Search Engine” Under the DSA

ChatGPT is no longer being treated in Europe simply as an AI chatbot.

On August 31, 2026, the European Commission officially designated ChatGPT as a Very Large Online Search Engine (VLOSE) under the European Union’s Digital Services Act, or DSA.

The decision places OpenAI’s service in the same regulatory category reserved for online search services with exceptionally large audiences in Europe.

According to the Commission, ChatGPT reaches at least 45 million average monthly users in the European Union, the threshold required for a service to receive the “very large” designation.

Reddit and Roblox were designated at the same time, although they are classified as Very Large Online Platforms rather than search engines.

For ChatGPT, however, the terminology may be just as significant as the additional regulation.

The European Union is effectively recognizing that an AI assistant capable of retrieving and presenting information from the web can function as a search engine, highlighting how rapidly the boundary between traditional web search and conversational AI is disappearing.

Why Is the EU Calling ChatGPT a Search Engine?

ChatGPT originally became popular as a conversational AI system capable of generating answers from models trained on large quantities of data.

That role has evolved considerably.

Modern versions of ChatGPT can search the web, retrieve current information and combine information from multiple online sources into conversational answers.

For regulatory purposes, the European Commission now considers those capabilities sufficient for ChatGPT to qualify as an online search engine under the DSA. Reuters also reported that the Commission considers the AI system to fall within the DSA definition of an online search engine.

This distinction matters because traditional search engines generally return pages of links that users must evaluate themselves.

AI assistants increasingly perform part of that selection and interpretation automatically.

Instead of asking Google for a list of websites, a user can ask ChatGPT a question and receive a synthesized answer directly.

That gives conversational AI systems a growing role in deciding which information becomes visible to users — and how that information is presented.

The 45 Million User Threshold

The DSA defines services with at least 45 million average monthly users in the European Union as potentially qualifying for its highest level of oversight.

That figure corresponds to approximately 10% of the EU population.

ChatGPT has now crossed that threshold, according to user figures reported to European regulators.

The designation does not mean that ChatGPT has violated European law.

Instead, reaching this scale automatically triggers additional responsibilities because the EU considers services of this size capable of having broader effects on society.

OpenAI now has four months following the designation to comply with the additional obligations associated with VLOSE status.

What Will OpenAI Have to Do?

The DSA requires very large online platforms and search engines to go beyond the obligations applying to smaller digital services.

One of the most important requirements is the identification and assessment of systemic risks associated with the service.

For ChatGPT, these could potentially include risks connected with illegal content, fundamental rights, public security, electoral processes, the protection of minors and users’ physical or mental well-being.

Where significant risks are identified, the provider is expected to introduce measures designed to mitigate them.

Very large services are also subject to stronger transparency and accountability requirements.

The DSA framework includes independent audits, internal compliance functions, additional access to information for regulators and, under certain conditions, access to platform data for vetted researchers.

The Commission therefore gains significantly greater visibility into how a service operates once it enters the VLOSE or VLOP category.

Exactly how every DSA obligation will translate into the conversational interface of ChatGPT will be particularly interesting to watch.

Rules originally designed around search engines and large online platforms now have to be applied to a system that generates a new answer for every request.

ChatGPT Is Becoming Part of Europe’s Search Regulation

The designation illustrates a broader transformation already underway on the internet.

For years, accessing information online generally meant navigating from a search engine to external websites.

Generative AI changes that relationship.

A conversational assistant can search, select, summarize and explain information without requiring the user to visit every underlying page.

That makes AI assistants increasingly influential intermediaries between publishers, information sources and users.

The European Commission’s decision does not determine whether ChatGPT will ultimately replace conventional search engines. But it demonstrates that European regulators already consider its search capabilities significant enough to warrant the same enhanced regulatory framework applied to very large search services.

For OpenAI, this means ChatGPT’s expansion into search brings not only opportunities but also responsibilities traditionally associated with the largest internet gatekeepers.

The DSA and AI Act Will Now Overlap Around ChatGPT

The timing is also notable.

On August 2, 2026, important provisions of the EU AI Act became enforceable, including new transparency obligations covering certain AI systems and AI-generated content.

The DSA and AI Act are separate pieces of legislation, but a company such as OpenAI can increasingly find itself subject to both.

Broadly speaking, the AI Act focuses on artificial intelligence systems and models, while the DSA focuses on the responsibilities and societal risks associated with large digital services.

ChatGPT sits directly at the intersection.

It is simultaneously an AI system, a consumer application and, according to the European Commission, a major online search service.

That combination may make ChatGPT one of the most closely watched examples of how Europe’s different digital regulations interact in practice.

What Happens If OpenAI Does Not Comply?

The VLOSE designation should not be confused with an accusation of wrongdoing.

However, once the additional DSA requirements become applicable, the Commission has substantial enforcement powers.

If a breach is ultimately established, penalties under the Digital Services Act can reach up to 6% of a provider’s worldwide annual turnover, depending on the nature and severity of the infringement.

The Commission can also require corrective measures.

Those potential penalties illustrate why the designation is more than an administrative label.

Compliance with European digital regulation is becoming an increasingly important part of operating a global AI service at ChatGPT’s scale.

AI Assistants Are Becoming Information Gatekeepers

Perhaps the most important part of the announcement is what it says about the evolution of AI.

ChatGPT began as a system people primarily used to generate text, answer questions and experiment with large language models.

It is increasingly becoming an interface through which people find information, compare products, research subjects and navigate the web.

Regulators are beginning to adapt accordingly.

By formally placing ChatGPT in the category of a Very Large Online Search Engine, the European Union is acknowledging that conversational AI has moved beyond the boundaries of a traditional chatbot.

The next question is how rules designed for the previous generation of internet search will adapt to AI systems that do not simply rank information — but read, combine and explain it on the user’s behalf.

That may ultimately prove more important than the regulatory label itself.
