The balance sheet of Cannes Lions 2026 records an axis shift from the technology itself to its use. The festival’s dominant theme was agentic AI: systems that set their own goals and execute tasks with minimal human intervention. The accompanying second finding was discussed less but stated more firmly — generative models that produce content in place of humans stepped off the stage, while assistive tools that quietly carry the workload moved to the centre. OpenAI’s chief revenue officer described the era as a shift from the awareness economy to the intelligence economy.
The creative side’s rationale was commercial, not romantic: audiences detect AI-generated content fast, and the moment they do, they begin withdrawing their belief in the brand. As the production barrier falls, agencies’ value relocates too — from execution to strategic intelligence, cultural fluency and creative judgment. Against everything the machine makes cheaper, one asset refuses to get cheaper: the judgment that decides what will not be published.
