AISEOSeptember 6, 2026by Elisa Murphy0ChatGPT Is Now A Very Large Online Search Engine In The EU

EU law treats ChatGPT as a very large online search engine. That label applies when a service has more than 45 million average monthly users in the EU under the Digital Services Act. The status triggers VLOSE duties.

Those duties can include risk reviews, transparency reports, regulator access to data, and stronger checks on illegal content. You will see how ChatGPT differs from search engines, what its EU legal status means, and where search authority has limits.

First, that classification determines how EU search regulation will apply.

How ChatGPT Classification Impacts Search Engine Regulation

This classification expands the search engine rules that apply. In the EU, it brings stricter DSA checks for search services. Per Policy Review, ChatGPT reached 45 million active EU users, which supports applying these duties once the DSA threshold is met.

There is a catch. The European Commission said the groups are linked, so your duties may overlap. The Commission will watch your feature growth over time.

Comparison: ChatGPT vs Traditional Search Engines in EU

After that ruling, you can use the table below to compare five key points between ChatGPT search and traditional search in the EU.

Point	ChatGPT search in the EU	Traditional search in the EU
DSA status	The European Commission designated it a very large online search engine on August 31, 2026.	They can fall in the same DSA category if their EU reach is large enough.
Why it counts	It is a hybrid service because it answers prompts and can search the web.	There, the core service is web search for user queries.
EU scale	OpenAI reported about 159.1 million average monthly recipients, over 3x the 45 million line.	The same 45 million threshold is the trigger for the largest search services.
Compliance clock	It has four months from notice to meet extra DSA duties.	Their covered peers face the same four-month clock.
Scrutiny	Henna Virkkunen said it will face a “higher standard of scrutiny and accountability.”	They face that same DSA standard, and fines can reach 6% of global annual revenue.

What Is ChatGPT Classified As Under EU Law

ChatGPT is a VLOSE in the EU. Under the Digital Services Act, that means a very large online search tool with at least 45 million average monthly users in the EU. The legal term is clear. The European Commission lays out oversight and your rights.

There are stricter DSA rules. For you, that status can mean public reports, risk checks, and ways to complain, as the DSA user rights overview explains.

How To Comply With VLOP Obligations As ChatGPT

Here are five clear compliance steps.

1. Map the EU search features you offer as a very large online search engine and link each one to a DSA duty. Barata said only some functions qualify as search, and they do not fit the DSA’s three main groups neatly.
2. Run yearly risk checks of design, algorithms, moderation, and data use. Laureline Lemoine of AWO said you should cover elections, minors, mental health, and civic discourse.
3. Retest each new feature before release when it could have a “critical impact” on systemic risk. Mathias Vermeulen of AWO called the DSA’s due diligence regime a “tough reality check.”
4. Explain how outputs are moderated and how you should interpret accuracy limits. Natali Helberger of the University of Amsterdam said the DSA can reach moderation transparency and risks tied to how people use it.
5. Build an Article 40 process for vetted researcher access and keep records of each step you take to reduce risk. You may get requests for deeper data if their review needs it.

Common Questions About ChatGPT Search Engine Status

These answers cover four key questions.

• Why is this getting attention? Search Engine Journal says ChatGPT is now called a “very large online search engine” in the EU, which helps explain the added attention. It is a legal status.
• Does your market matter? Yes, the status applies in the EU, so your market matters. If you reach EU users, you should track how often AI answers mention your brand, products, facts, and site pages.
• Should you care now? Yes, you should care now. It can shape the sources and claims you see first.
• Why are agencies updating advice? There is a business reason. Agencies are updating advice because they know AI mentions can affect your traffic, leads, and trust with buyers.

Drawbacks When Treating ChatGPT As Search Engine Authority

With those basics settled, you should weigh four limits before you treat ChatGPT as a search engine you trust in the EU.

• Scale is not proof: Founders Dispatch reported that 45 million average monthly EU users trigger direct Commission oversight, and that reach does not prove truth.
• Regulation is not endorsement: Henna Virkkunen said the label brings “a higher level of scrutiny and accountability,” so you should read it as oversight, not trust.
• Answers can be hard to check: the Commission’s hybrid search view points to clear answer systems and researcher data access because you may not see enough proof in the reply itself.
• Compliance can shape the product: with four months to meet added rules and an annual supervision fee capped at 0.05% of net income, you may see tradeoffs in ads, reports, and content controls.

Key Differences Between ChatGPT And Traditional Search Engines

You can compare four key differences below as ChatGPT now sits closer to a very large online search engine in the EU.

Key point	ChatGPT	Traditional search engines
Answer style	It writes a direct reply and can refine it in the same chat.	They show ranked links and snippets for you to scan.
Content role	It finds information and generates new text from it.	They mainly point you to content published elsewhere.
Product shape	Its prompt history and custom GPT tools add platform-style features.	Their core job is search, so there is less feature overlap.
EU signal	OpenAI said its search feature reached 120.4 million average monthly EU users by Sept. 30, 2025, above the DSA’s 45 million line.	The European Commission said the search and platform categories are “becoming more and more intertwined,” highlighting a gap that classic search did not create as sharply.

For EU users, the direct answer is now clear. ChatGPT now counts as one in Europe. Under the EU Digital Services Act, services that pass an average of 45 million monthly users face tighter search-related duties.

That makes ChatGPT a very large online search engine in the EU. Scale brings new limits. You will need to watch how risk reviews, ranking clarity, and content safeguards affect search visibility and traffic decisions.

Reach alone will not decide. Your next move is simple: track EU referral trends and test whether ChatGPT search earns a place in your content plan.
