Pros and Cons of Agentic Media Buying
This Digiday analysis (May 11, 2026) examines the debate around agentic media buying — AI-driven, agent-to-agent approaches that autonomously negotiate media buys. Proponents (including some agencies and publisher technologists) argue agents can cut ad‑tech intermediaries, push more budget to publishers, optimize performance at machine speed, and accelerate a flight-to-quality toward premium, first‑party inventory. Critics, including voices at The Trade Desk and publisher and agency leaders, warn agentic trading could add new layers of opacity, replicate ad‑network fragmentation, harm the open exchange, and be misused to prioritize outcomes without human oversight. The practice remains nascent with very little money transacted; several holding companies and agencies (Omnicom, Stagwell, Butler/Till) are testing agentic workflows while industry observers stress governance, transparency and broader platform-driven traffic declines mean agents are unlikely to be a standalone fix for publisher monetization.
Agentic media buying could materially affect programmatic supply paths, publisher revenues and transparency but remains nascent and unproven; industry players are testing its use.

- Omnicom CEO John Wren said the holding company was testing agent-to-agent media buys.
- The Trade Desk’s Jeff Green said on an April 7 earnings call that agentic buying only works at the scale of the open marketplace, not one-to-one buyer-seller agent pairs.
- Agencies/companies mentioned as testing or pushing agentic buying include Stagwell and Butler/Till; Raptive has a proof-of-concept exchanging small budgets.
- Industry consensus in the article: agentic trading is still nascent with very little spend and operational complexity.

State of Agentic Advertising Report
Digiday and Optable published a sponsored State of the Industry report based on a survey of 180 agencies, publishers, brands and retailers about the adoption and impact of agentic advertising. The report finds the market is largely in early-stage experimentation (31% fragmented, 42% early but moving quickly), with advertisers (89%) and agencies (92%) adopting agentic AI faster than publishers (29% actively deploying). Investment is focused on media buying optimization (70%) and measurement (58%), while barriers include technical complexity, interoperability, governance and brand-safety concerns. The piece highlights emerging open protocols (AdCP, MCP, AAMP) and calls for improved publisher data readiness, identity infrastructure and cross-industry standards to scale agentic workflows.
AI Agents Increasingly Handle Ad Dollars
The article discusses the growing but still experimental use of AI agents in advertising. Companies like Apostra, The Trade Desk, PubMatic, Magnite, and Kargo are developing agentic systems for media buying. Apostra has handled about $1.2 million in ad buys over three months, and Rouge Care reported a fivefold ROAS on CTV ads via PubMatic's AgenticOS. However, highly autonomous deployments represent less than 5% of marketing use cases in 2025. Protocols like AdCP, AAMP, and Amazon's MCP are emerging, but fragmentation risks interoperability. Responsibility for agent decisions remains unclear, and premium advertising remains relationship-driven.
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.
