IAB Tech Lab Introduces New OpenRTB Attributes for Live Content

On April 28, 2026, IAB Tech Lab, recognized globally as a leader in establishing technical standards for digital advertising, revealed a series of new attributes aimed at improving the clarity surrounding live content in programmatic transactions. The introduction of these attributes is vital due to the growing consumption of live events through digital mediums, including sports and entertainment. The public comment period for these changes is open until May 28, 2026, and industry feedback is actively encouraged.

The updates encompass standardized bidstream signals that allow advertisers and publishers to clearly define whether content is live, real-time, or classified as a first broadcast. As programmatic channels increasingly engage with live content, there is a pressing need for advertisers to adapt their strategies to ensure that they can effectively utilize their budgets, which may require rapid spending over short timeframes. Anthony Katsur, CEO of IAB Tech Lab, emphasized the importance of these improvements by stating, "As more live events move into programmatic channels, a total shift in strategy is needed; buyers must condense weekly budgets into mere hours."

Enhancements in Signal Clarity

One significant aspect of the update is the clarification of an existing field in the OpenRTB framework alongside the addition of two new optional fields designed to communicate the "liveness" of content in bid requests. These new fields are intended to guide sellers as they characterize the nature of live content. Specifically, they delineate content that is occurring simultaneously with a bid request, content that is streamed in real time but is not live, and content that is within its initial scheduled broadcast window. This critical enhancement allows buyers to receive more context when evaluating potential inventory, enabling them to make better-informed bidding decisions.

Improved Pricing Communication

Another crucial update pertains to the substitution macros, refined to allow for a more transparent transmission of price-related information within the bidstream. This adjustment aims to facilitate clearer communication of discounts and net pricing, thereby promoting better alignment between supply and demand platforms from a pricing perspective. Such clear signaling is essential in today's complex programmatic landscapes, where precision can determine the success of a campaign.

As the landscape of digital content continues to evolve, particularly with the increasing popularity of connected TV (CTV) and live event inventories, these enhancements not only streamline communication between buyers and sellers but also augment the ability to effectively monetize live media assets. Rob Hazan, General Manager of Product Management at The Trade Desk, remarked, "Live content signals help us better understand the context of live inventory so we can deliver buyers' budgets effectively. This enables agencies and advertisers to better achieve their marketing goals and sellers to more effectively monetize their most valuable media assets."

Call for Public Engagement

The development of these new specifications was driven by the efforts of the Programmatic Supply Chain Commit Group, an initiative designed to bring together industry stakeholders focused on enhancing programmatic capabilities. During the public comment period, IAB Tech Lab is encouraging input from industry participants, with a view to refining the specification updates that will ultimately be adopted across the digital advertising ecosystem.
