The EU AI Act timeline
As of April 2026, there have been some key updates to the EU AI Act timeline.
The EU Artificial Intelligence Act has entered a critical phase in 2026, marking the shift from regulatory preparation to active compliance and enforcement. While the Act came into force in August 2024 and initial obligations began to apply in 2025, 2 December 2027 is the key milestone when the majority of requirements become applicable to organisations using AI systems.
