The EU AI Act entered its enforcement phase in early 2026 with the AI Office now operational. High-risk AI system requirements are binding, and the Commission has signaled willingness to act against non-compliant systems. Major US platforms using generative AI in the EU market are the most likely first targets. However, regulatory timelines typically slip, and political considerations around US-EU trade tensions may delay formal action.
