Buyer Agent

Buyer Agent is WPP Media's agentic artificial intelligence product for automated video advertising procurement, operating within the WPP Open platform. Unveiled at the Cannes Lions advertising festival on 18 June 2026, it uses large language model reasoning to evaluate inventory options, audience data, and campaign objectives and then negotiate and place video advertisements across streaming and broadcast supply chains. WPP routes more than $8.5bn in annual media spending through the system.

At its launch, WPP convened an Agentic Standards Initiative built around the Model Context Protocol (MCP) with six major media rights holders, Disney, Netflix, Fox Corporation, NBCUniversal, Paramount Skydance, and Comcast's FreeWheel, with IAB Tech Lab and Prebid providing technical-standards backing. The initiative aims to establish common protocols so that AI buying agents from any agency can communicate with publisher inventory systems through a consistent interface, rather than through bespoke bilateral integrations.

Buyer Agent represents WPP's move to position agentic AI as a core operational layer rather than a supplementary tool. Where conventional programmatic bidding relies on rules-based systems, the Buyer Agent reasons over constraints and objectives in a more flexible, goal-directed manner. The scale of spending committed and the breadth of the Coalition assembled at launch make it a reference product for the emerging category of AI-driven media procurement.
