Digiday Summit: Bayer, OMD Share Agentic Ad Buying Guardrails

At the Digiday Programmatic Marketing Summit, Bayer revealed it uses spending caps and human sign-off requirements for all AI agent optimization decisions.

Attendees reported AI hallucinations producing incorrect CPMs that could cost agencies real money, underscoring the need for QA processes to 'grade the agent's homework.'

The bottom line: Document your AI governance rules before scaling agentic buying: spending caps, human approval gates, and error monitoring are becoming standard practice for enterprise advertisers.
