The Trade Desk Launches Agentic Advertising Tools
The Trade Desk announced the introduction of "Koa Agents," AI-based agents designed to take over operational tasks in programmatic media buying, and an "Open Agentic Kit," an integration framework to embed those agents into third-party platforms. The agents are intended to let media buyers set goals rather than manually configure many parameters, with the system handling planning, audience selection, activation and continuous optimization via a dialog-based interface. Global agency group Stagwell is testing the technology in a closed beta by integrating Koa via the Open Agentic Kit into its in-house media platform. The story positions The Trade Desk’s moves amid a broader industry push toward agentic advertising, noting parallel efforts such as the IAB Tech Lab’s Agentic Real Time Framework (ARTF) and Pubmatic’s "Agentic OS," and raises interoperability and vendor-dependency considerations for advertisers.
Agentic Automation Hits Both Sides of Programmatic
Three industry vendors announced agentic measurement and activation capabilities: Measured released an MCP server that lets marketers query incrementality and performance via chat interfaces backed by large-scale tests, while Adform and Adsquare launched an Agentic Real‑Time Framework integration that enables autonomous signal activation inside a DSP at bid time. An AdExchanger op‑ed quantified the opportunity cost of slower reporting — arguing millisecond-level autonomous decisions would make weekly or quarterly reporting obsolete. Measured’s CEO Trevor Testwuide framed AI chat as the new primary interface for incrementality intelligence. The combined releases shift measurement and decision logic deeper into the media stack, posing structural disruption to agency planning cycles (especially mid‑tier agencies) and altering how media is valued and bought in programmatic auctions.
IAB Tech Lab Releases Agentic Roadmap; Agentic Ads Grow
The IAB Tech Lab published an Agentic Roadmap to help the ad industry scale agentic (multi-step, autonomous) AI buying and selling while minimizing workflow fragmentation. The roadmap builds on existing standards such as the Model Context Protocol and the Tech Lab’s Agentic RTB Framework and Global Privacy Protocol; the Tech Lab also said it is making an unspecified engineering investment in AI. Separately at CES, Omnicom Media announced a tie-up with Walmart to connect purchase data to Omnicom’s influencer efforts on Instagram via agency Creo’s Influencer Discovery Agent. Walmart is rolling ads into its AI shopping agent Sparky as “sponsored prompts,” and it is beta-testing an advertiser-facing AI avatar, Marty, with wider access planned in H1 2026. The roundup also notes other industry moves (Trade Desk publisher support for OpenAds, PMG’s acquisition of Digital Voices, DoubleVerify integrating IMDb data) and a Microsoft AI executive hire.
