The IAB Tech Lab has released its Live Event Ad Playbook (LEAP) Implementation Guide for public comment until November 23, 2026. The guide provides standardized practices for the Forecasting and Concurrent Streams APIs to help publishers and advertisers manage high-demand live streaming events.
Standardizing these APIs addresses the technical strain caused when millions of viewers hit simultaneous ad breaks during live sports. By providing a shared playbook for The Trade Desk, Amazon Ads, and Index Exchange, the industry can move away from fragmented, custom integrations that often fail during sudden traffic surges. This move signals a shift toward a more automated, programmatic approach to live streaming that mirrors the efficiency of static VOD environments. As live streaming continues to capture larger shares of linear TV budgets, the industry must now watch for the adoption rate of version 1.1 and the subsequent rollout of standardized ad pre-fetching protocols.
