In a few days, the EU will categorize ChatGPT as a "very large online platform" and include it under the DSA regulation

According to 1M AI News monitoring, the European Commission plans to classify OpenAI's ChatGPT as a "very large online search engine" under the Digital Services Act (DSA) framework in the coming days. Germany's Handelsblatt first reported this decision, citing internal European Commission sources.

The DSA imposes regulatory requirements on very large platforms and very large search engines, with the latter additionally required to comply with obligations related to recommendation algorithms and advertising transparency. The threshold for triggering these obligations is monthly active users in the EU exceeding 45 million, and ChatGPT's active users in Europe have already surpassed 120 million, well above this standard.

An important timing note: OpenAI recently started testing advertising features in ChatGPT. The advertising transparency provisions of the DSA will require OpenAI to disclose the operation logic of its recommendation system and advertising delivery mechanisms. Non-compliance with the DSA could result in substantial fines; Platform X was fined €120 million at the end of 2025 for breaching transparency obligations.
