OpenAds Unveiled: The Trade Desk's Bold Auction Revolution
At the Prebid Summit in New York, The Trade Desk detailed OpenAds, its Prebid-like auction that requires universal Transaction IDs (TIDs) and TID sharing. OpenAds features include Auction Code Attestation and Auction Audit (the latter revealing discrepancies between publisher Google Ad Manager settings and auction handling by SSPs/resellers via the PubDesk dashboard). A new Sincera Integrity Signal aims to prevent bidstream tampering. TTD asserts OpenAds and PubDesk inform buyers and aim for a fair auction for all parties, while not abandoning Prebid; they plan to fold Prebid features in over time and maintain a code repository. The event highlighted ongoing tensions with Prebid over forking and governance, with executives stressing the need for balance among buyers, sellers, publishers, and resellers, amid broader industry debates about transparency and control in the open web ecosystem.
Trade Desk Unveils New Prebid Initiative for Sell-Side
The Trade Desk is expanding its sell-side initiatives by planning a branched-off version of Prebid that would include its Transaction ID signal. This builds on earlier sell-side efforts such as OpenPath (2022) and S&P500+ (2024), with Jeff Green announcing the new Prebid-based approach. The Transaction ID signal would be integrated via Prebid’s wrapper, and more details are expected to be shared at the upcoming Prebid Summit. The move aims to improve inventory quality and prune out resellers, though publishers have raised concerns about the potential impact on their workflows. The industry context frames this as part of a longer history of ad-tech experimentation with sell-side dynamics and transparency, a topic that continues to provoke debate among buyers, sellers, and platforms.
TTD Responds to Prebid's Transaction ID Update
The Trade Desk (TTD) announced OpenAds at the October 2025 Prebid Summit, forking Prebid’s open-source codebase to create a parallel, open-internet auction framework. OpenAds restoration of a universal TID per impression aims to improve cross-exchange deduplication and transparency, while enforcing direct demand paths with anti-fraud safeguards. TTD also unveiled PubDesk, a real-time publisher dashboard, and OpenPath, its direct DSP-publisher connection infrastructure, integrated to support auditable auctions. The move responds to Aug 2025 Prebid.org updates enabling publishers to use different Transaction IDs (TIDs) for the same impression across partners, which undermined universal TID. OpenAds is described as high-integrity and partially open-source, with a governance stance that reduces reliance on Prebid.org’s sell-side-dominated board. Publishers and SSPs face a bifurcated landscape depending on adoption of OpenAds versus Prebid’s framework.
