The IAB Tech Lab introduced a new technical specification on February 19, 2026, to address planning hurdles in programmatic streaming. The global standards body released the Live Event Ad Playbook (LEAP) Forecasting API for public comment to standardize inventory discovery.
The proposal gives content owners a structured way to share metadata—such as event schedules, expected ad breaks, and viewership forecasts—with demand-side platforms (DSPs) and exchanges before events begin, according to the IAB Tech Lab.
Linear Predictability for Digital Environments
The programmatic ecosystem has traditionally struggled with "tune-in" moments. While linear television relies on upfronts and scheduled slots, digital buying often remains reactive or siloed within private marketplaces. The Forecasting API brings linear-style predictability to the digital space by aligning with existing OpenRTB and AdCOM standards.
Anthony Katsur, CEO of IAB Tech Lab, noted that live events remain technically complex despite their value. He stated the proposal makes future live inventory visible and actionable, giving buyers and sellers the tools to plan.
Integrating the LEAP Initiative
The Forecasting API represents the second phase of the LEAP initiative. It follows the Concurrent Streams API, which helps ad tech platforms monitor live audience scale in real-time. By moving "upstream" in the workflow, the Forecasting API enables automated deal creation via integration with the Deals API.
Major industry players support the standard. Alex Combs, VP of Ad Products at Disney Entertainment & ESPN, indicated these standards help manage premium sports and news inventory. Daniel Perry-Zucker of The Trade Desk highlighted that standardizing communication regarding upcoming inventory improves monetization and the consumer experience by adding speed and predictability to live advertising.
Synchronizing Performance and Live Broadcasts
For performance marketers and affiliate managers, this standard signals a shift in how live events bridge with performance goals. Having a clearer view of upcoming inventory allows managers to coordinate affiliate campaigns with live broadcasts. This ensures that creative assets and offers align with peak viewership periods.
The public comment period for the Forecasting API remains open through March 20, 2026. Industry stakeholders may provide feedback on the schema before it becomes an official standard.
