The EU AI Act officially entered into force in stages throughout 2025, and as of early 2026, organizations deploying AI systems in or serving the European Union must comply with its provisions. This regulation is the most comprehensive AI-specific law in the world, and its ripple effects extend well beyond Europe.
The Act classifies AI systems into four risk tiers: unacceptable risk (banned outright), high risk (subject to strict requirements), limited risk (transparency obligations), and minimal risk (no specific requirements). Most enterprise AI systems -- including those used in hiring, credit scoring, medical diagnostics, and critical infrastructure -- fall into the high-risk category.
For organizations, compliance means implementing risk management systems, ensuring data governance, maintaining technical documentation, enabling human oversight, and meeting accuracy and robustness standards. The penalties for non-compliance are significant: up to 35 million euros or 7% of global annual turnover, whichever is greater. The time to prepare is not tomorrow -- it is now.
