AdTech & Monetization Market: Agentic Advertising Rebuilds, Not Removes, Intermediaries
This AdExchanger opinion piece (The Sell Sider) argues that 'agentic advertising'—the use of AI agents to plan, package and execute media buys—risks recreating the same intermediary complexity publishers experienced with SSP proliferation. The article notes publishers historically integrate dozens of SSPs to chase incremental demand and warns buyer and seller agents will encode incentives that favor favored supply paths, potentially biasing spend. It recommends a disciplined publisher strategy: define a primary sales agent, build a small set of specialized agents, standardize payment/clearing, and participate selectively in external ecosystems. The piece highlights that settlement and payment control (clearinghouses) may determine influence more than the agent implementations themselves.
Analysis highlights a structural risk for publishers and buyers: agentic systems could reintroduce supply-path duplication and bias similar to SSP sprawl, affecting monetization, settlement flows and industry economics.
