Programmatic Gets an Agentic Brain
AdExchanger publishes a podcast interview with Scott Ensign, chief strategy officer at independent agency Butler/Till, about using agentic AI to change programmatic buying. Butler/Till ran an experiment with PubMatic to execute a fully autonomous, end-to-end agentic CTV campaign for Geloso Beverage Group using PubMatic’s Agentic OS and a generative AI environment. The agency reported cutting supply chain and tech costs by roughly 80%, achieving 40% more impressions on the same budget, a 98% video completion rate and under 1% waste. Ensign argues buyers must redefine efficiency and take a more active role policing supply chains; he expects human buyers will remain but be heavily augmented by agentic technologies. The piece also references a dispute between AgenticAdvertising.org and the IAB Tech Lab over agentic protocols.
Demonstrates practical agentic AI application in programmatic CTV with substantial reported cost and efficiency gains, suggesting meaningful operational shifts for media buyers, DSPs and supply-chain quality practices.

PubMatic Unveils Fast-Track OS for Agent-Based Advertising
PubMatic has launched an "Agentic OS," a Nvidia-accelerated operating system for agent-based programmatic advertising that aims to enable "Agent-to-Agent" workflows where specialised AI agents plan, execute, optimise and monitor campaigns autonomously. Early partners including WPP Media and MIQ will test agentic campaigns under real market conditions. The three-layer architecture (infrastructure, application/agentic functions, transaction layer) claims up to fivefold faster decisioning, sub-millisecond reaction times and fewer auction timeouts. Agentic functions operate via protocols such as the Ad Context Protocol (AdCP) and the Model Context Protocol (MCP) and automate planning, pacing, optimization, troubleshooting and measurement. PubMatic integrates Agentic OS with existing programmatic buying models (Programmatic Guaranteed, Private Marketplaces) and routes media via its Activate buying platform. PubMatic positions the approach as particularly relevant for complex environments like CTV, while noting adoption will depend on control, transparency and scalable governance in practice.
Agentic media buying requires client-by-client setup
Independent agency Butler/Till has been testing agentic programmatic media-buying agents for months and has run at least half a dozen new tests since May. Early experiments began in CTV and have expanded to online video, display and streaming audio. Butler/Till’s chief strategy officer, Scott Ensign, says governance and guardrails must be configured on a client-by-client basis because different clients and channels carry different risk tolerances. Current ad spend routed through these agentic systems is small (low single-digit percentages), though Ensign expects the proportion to grow over time.
2026: The Rise of Autonomous AI in Media Buying
Industry voices interviewed by Adzine describe 2026 as an inflection point for 'agentic' AI in media trading: autonomous AI agents are beginning to act as decision-makers that build audiences, select placements and adapt creatives in real time. Participants from Quantcast, Equativ, Adform, Revo/Love and Traffective report practical deployments in repeatable, transactional scenarios while stressing limits where strategic judgment, complex budget trade-offs and liability are required. First‑party, machine‑readable real‑time signals are highlighted as critical fuel for effective agentic workflows. Experts call for common standards and protocols (IAB Tech Lab Agentic Roadmap, AdCP, MCP) to enable interoperable agent-to-agent interactions, evaluation and accountability. The consensus forecasts growing agentic automation in operational programmatic tasks in 2026, but a hybrid model retaining human responsibility and oversight for strategy and governance.
