Index Exchange has detailed the mechanics of the IAB Tech Lab's Agentic Real-Time Framework (ARTF), a new standard designed to execute programmatic trading logic within containerized environments directly inside auction infrastructure. By moving decisioning intelligence locally to the exchange, the framework aims to reduce programmatic bid latency by up to 95% and lower cloud compute costs. The system allows ad verification, identity, and bid enrichment tools to pitch changes in under 10 milliseconds before bid requests reach DSPs.
The ARTF shifts the programmatic paradigm from external serial calls to localized parallel execution. For streamers and publishers, this means higher bid density and more enriched data signals without the performance tax typical of complex ad tech stacks. By standardizing how AI agents and logic-heavy containers plug into exchanges, the framework prevents the fragmentation of agentic advertising. For the broader ecosystem, it provides a scalable blueprint to handle high-frequency CTV and live sports impressions where millisecond-level decisioning is critical. Watch for widespread SSP adoption of ARTF-compliant environments throughout early 2027.
The IAB Tech Lab released ARTF v1.0 for public comment in November 2025, with the specification introducing containerized architecture for interoperability across programmatic advertising. The initial release targeted an 80% reduction in bid request and response times, with the extended comment period running through January 15, 2026. The framework has since evolved to claim up to 95% latency reduction as production testing advanced.
Index Exchange served as a primary contributor to the ARTF development, with Joshua Prismon, the company's chief architect, describing how containerized models allow companies to integrate specialized capabilities directly into exchange infrastructure. The framework was shaped by a working group that included Amazon Ads, Yahoo DSP, Basis, Chalice, Publicis Group's Epsilon, Netflix, Optable, Paramount, and WPP, among others. Chalice was among the first vendors to deploy its full model within Index Exchange's infrastructure as a proof of concept.
The ARTF operates by having host platforms, typically SSPs, run partner containers inside their own data centers. Each container executes proprietary logic and returns a suggested mutation to the bid request via a standardized API, with the entire process completing in under 10 milliseconds. This replaces the legacy model where bid requests traverse multiple external systems and public clouds, each adding hundreds of milliseconds. The specification also describes a standard interface for managing containers using AI agents, enabling sub-millisecond real-time bidding operations driven by agentic systems.
