Ad Tech Rewritten by Agentic AI, Intent and Transparency
This ExchangeWire opinion piece compiles ad tech experts’ views on the forces reshaping the industry in 2026. Contributors highlight agentic AI and conversational interfaces driving a shift from destination-based browsing to intent-driven discovery, where the "moment of intent" is captured upstream of publishers. Privacy regulations and the decline of third-party IDs are accelerating moves toward contextual and privacy-first solutions. The article discusses emerging technical concepts and protocols — including the Ad Context Protocol (AdCP) and IAB’s ARTF containerised workflows — that may reduce manual planning friction and enable earlier sell-side decisioning. Experts also describe a K-shaped M&A environment favoring specialized, transparent vendors, growing scrutiny on supply quality, and the risk that easily replicated execution tools will lose value unless they demonstrably add differentiated utility.
Synthesises practitioner viewpoints on agentic AI, intent-driven discovery, privacy-driven identity shifts, new protocols (AdCP) and sell-side decisioning — trends that inform product, buying strategy, M&A and compliance planning across ad tech.

Agentic AI and Quality Rewriting AdTech in 2026
Industry leaders tell ExchangeWire that ad tech in 2026 is being reshaped by the rise of agentic AI, accelerating autonomous media buying, and by legal and regulatory pressure on large platforms. Generative AI remains influential, but ‘agentic’ systems — agents making or coordinating decisions — are moving media buying toward greater automation. At the same time, global privacy rules and the ongoing decline of third-party identifiers are pushing advertisers toward consented first-party data, clean rooms and contextual approaches. Buyers prioritise quality, transparency and supply-path consolidation over scale, while short-form vertical video and DOOH formats gain spend. The piece highlights operational challenges — data quality, fragmented infrastructure, fraud and copyright/piracy issues — and positions incrementality, unified measurement and infrastructural integration as central industry priorities.
Agentic Ad Tech: Revolution or Confusion Ahead?
Shirley Marschall breaks down the frontiers of agentic ad tech in early 2026, prompted by CES momentum, and notes growing confusion rather than clear consensus. The piece catalogs a proliferation of agentic protocols and architectures—Ad Context Protocol (AdCP), the IAB Tech Lab's Agentic Real-Time Framework (ARTF), LiveRamp's User Context Protocol (UCP), Anthropic's Model Context Protocol (MCP), and Google's Agent2Agent (A2A)—highlighting different origins and goals but a shared question: what does agentic really mean, and how scalable or interoperable will it be? It contrasts two narratives: adopting a clean-slate, revolution view versus building on top of the existing programmatic stack. Adnami's Thomas From advocates a 'burn it all down' stance for AdCP, while the IAB Tech Lab encourages incremental progress. The piece emphasizes that adoption challenges and market dynamics—not mere tech prowess—will determine what actually sticks.
Agentic Ad Tech: Revolution or Evolution?
ExchangeWire columnist Shirley Marschall examines the rise of 'agentic' AI in ad tech following CES 2026 and highlights widespread industry confusion about what 'agentic' means in practice. Multiple competing protocols and frameworks have emerged—AdCP, IAB Tech Lab’s ARTF, LiveRamp’s UCP (donated to IAB Tech Lab), Anthropic’s MCP and Google’s Agent2Agent—raising questions about definitions, scale, interoperability and adoption. Industry voices split between rebuilding programmatic stacks (AdCP) and layering agentic capabilities on existing infrastructure (IAB Tech Lab). Contributors including Index Exchange CEO Andrew Casale, Adnami CPO Thomas From and IAB Tech Lab CEO Anthony Katsur underscore the tension between revolutionary and evolutionary approaches and note that practical adoption, not technology alone, will determine what sticks.
