AI Agents Summit 2026 (AIS26) is a flagship gathering for the global agentic AI ecosystem, taking place in Berlin from June 18–21. Held during Berlin Blockchain Week, the event explores how autonomous systems coordinate with each other and humans, create economic value, and operate safely across digital networks. The summit features three interconnected formats: Agent Arena, a live competition showcasing autonomous agents tackling real-world challenges with transparent leaderboards; an intensive Agents Hackathon spanning three days for builders designing production-grade agents, agentic commerce systems, and multi-agent architectures; and the Agentic Economy Forum.
