Short definition

The market surveillance authority is the Member State body responsible for enforcing the AI Act and acting on infringements of the Regulation. In Hungary this role belongs to the Minister for Economy and Energy, who also serves as the single point of contact; for high-risk systems in the financial sector, the Hungarian National Bank (MNB) acts instead. NAIH remains competent under the GDPR, not the AI Act.

The Union-level framework rules are set out in Articles 70 and 74; Hungary's designation is found in Act LXXV of 2025 and Government Decree 344/2025 (X. 31.). The market surveillance authority is entitled to open investigations, request documentation, carry out mystery shopping, and, under Articles 79–85, order corrective measures or withdraw a system from the market. Proceedings do not necessarily end in a fine: they often conclude with a non-monetary measure — setting a deadline to restore compliance — which is the more realistic, short-term risk for an average SME than a fine. As of April 2026, a significant number of Member States had still not formally notified their single point of contact, indicating that the institutional framework is still being built out.

Why this matters for an EU SME

In the short term, the more realistic risk is not a fine but a market surveillance measure — the best response to a regulatory inquiry is to present already-existing, documented classification and compliance material.
