Online Ad Summit 2026: More Agentic, More Open Web?
The Online Ad Summit 2026, a pre-Dmexco event, focused on the practical implications of agentic AI for the advertising industry. Industry leaders discussed the role of AI agents in media buying, with Sven Wegholz of Publicis Media noting that autonomy is real but scaling is the next step. Andrew Casale of Index Exchange cautioned against overhyping agents, stating they cannot replace programmatic infrastructure.

Overall, the summit underscored that while agents can streamline workflows, the fundamental issues of the open web, such as reach, frequency control, and measurement, persist.
