Empowering Publishers: AI Strategies for 2026 Success
Anthony Katsur, CEO of IAB Tech Lab, outlines a practical 'publisher protocol' for 2026 focused on three priorities: engaging with large language models and the emerging answers economy, addressing signal loss to maintain high-fidelity addressable audiences, and treating privacy as a persistent constraint. He highlights Trusted Server — an open-source edge component that moves signaling and ad execution off the browser into publisher infrastructure (Fastly/Akamai/Cloudflare) — as the heaviest lift but highest near-term revenue upside. Trusted Server enables server-side ad rendering, creates publisher-controlled server-side cookies, interoperates with existing ad servers and SSPs, and in tests improved page load times by roughly 300%. Katsur discusses early experiments with agentic workflows (buyer/seller agents), predicting acceleration through 2026 but true scale in 2027–2028, and forecasts a sell-side decisioning shift that could help publishers recapture premium yield.
IAB Tech Lab (a major industry standards body) is promoting an open-source Trusted Server and publisher-focused protocols that directly address signal loss, privacy-compliant identity recovery, and potential sell-side decisioning shifts — all of which could materially affect publisher revenue models and programmatic infrastructure.

Key Takeaways & Evidence Grounding
- Anthony Katsur is CEO of IAB Tech Lab and gave a Q&A about publisher priorities for 2026.
- Trusted Server is described as open-source software that runs at the publisher edge (e.g., Fastly, Akamai, Cloudflare) and moves signaling and ad execution off the browser into the publisher environment.
- In IAB Tech Lab tests, Trusted Server deployments improved page load times by roughly 300%.
- Katsur cited Safari as accounting for roughly 20–25% of browser market share and said ad blocking affects about 30–40% of inventory.
- Agentic workflows (buying/selling agents) are in early tests now, expected to accelerate through 2026, with scaled adoption unlikely until 2027–2028.

IAB Tech Lab Publishes 2026 Agentic Advertising Roadmap
IAB Tech Lab published its 2026 roadmap focused on 'agentic' advertising, CTV expansion, publisher signal restoration, privacy-first infrastructure, and supply-chain transparency. The Lab released open-source agentic reference implementations (Buyer Agent and Seller Agent SDKs v2.0), announced an Agent Registry (live March 3, 2026), and published v1.0 of an LLM Content Monetization Protocol (CoMP) API. It also delivered Trusted Server v1.0 with pilots planned for Q2 2026, outlined enhancements to Deals API and OpenRTB sidecar APIs, and prioritized OM SDK adoption and CTV measurement. IAB Tech Lab plans developer sessions, monthly Agentic Boot Camps in NYC, 30+ education events in 2026, and continued industry governance work including a Supply Chain Transparency Compliance Program.
Server-side Architectures Power the Next Era of AdTech
Publishers and advertisers are rapidly adopting server-side architectures to meet tightening browser restrictions, declining third-party cookies, and rising privacy expectations. Routing data through an organization’s own servers before sharing with vendors delivers greater control over data, resilience to browser-level blocking, improved site performance, higher data quality, and stronger privacy compliance. The transition is accelerating (an internal Addingwell estimate cites ~30–40% adoption across the top 1,000 websites), but migration brings challenges: infrastructure cost and complexity, first-visit consent latency, risks to signal integrity, and limited standardized audit logs. Best-practice server-side designs emphasize end-to-end pipeline ownership, vendor decoupling, consent enforcement at the infrastructure layer, signal verification, and robust logging. Industry efforts such as the IAB Tech Lab’s Trusted Server and vendor activity (Didomi’s acquisition of Addingwell) are shaping standardized approaches.
a16z Leads Series A in Private Network Startup doxxnet
Andreessen Horowitz (a16z) announced it is leading a Series A investment in doxxnet, a startup building a private, parallel internet infrastructure for individuals and AI agents. doxxnet offers a software-defined global network with non-Internet domains, encrypted peer-to-peer communication, and DNS-level threat protection, all without requiring personal information like email or phone. The company is founded by Barrett Lyon, known for Prolexic (acquired by Akamai), BitGravity, and Defense.net. The funding will support the development of its 'Agentic Defined Networking' concept, which allows users and their agents to configure and control the network. The announcement highlights growing privacy needs driven by AI agents that operate with access to user data.
