Omnicom Group

At Cannes Lions 2026, Omnicom returns to the Croisette with a Festival activation built around a single organizing idea: The Art of Influence — creativity engineered to change minds and move markets. Anchored by our Omnicom Space and a curated week of panels, salons, and client moments, the activation traces influence through its full arc — from attention to belief, belief to behavior, and behavior to growth — bringing together marketers, platform leaders, cultural voices, and editorial partners to examine how modern creativity earns trust when reach is a commodity, how data and craft combine to move people, and how cultural fluency translates into durable enterprise value.
