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.
Significant platform-level change in open web auction infrastructure with potential industry-wide implications.

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 OpenAds: A Game Changer for AdTech
Trade Desk CEO Jeff Green disclosed plans to take Prebid’s open-source code and build its own version, OpenAds, described by Green as part of a new lineup of sell-side products. At the Prebid Summit, he appeared on stage to offer more product details about OpenAds and a companion platform named PubDesk. AdExchanger’s Anthony Vargas summarized the event’s highlights, including tensions between DSPs, SSPs, publishers, and the Prebid project. The coverage also touched on ScreenShift in New York City, where TV industry participants discussed AI adoption and the enduring value of human-guided advertising amid high-production-value campaigns. Two weeks earlier, Green signaled the move to leverage Prebid’s code, signaling potential shifts in the ad-tech ecosystem. The event framed OpenAds and PubDesk as new sell-side products.
Publishers Report Double-Digit Gains from The Trade Desk OpenPath
Publishers told Digiday that The Trade Desk’s OpenPath has delivered generally strong revenue and yield gains over recent months, with several reporting double-digit CPM or revenue increases and some trialing OpenAds, which TTD launched last October. Publishers described short-term volatility—sharp dips and recoveries—and lingering transparency gaps that make diagnosing drops difficult. Some publishers said TTD is temporarily allowing duplicate bids for OpenAds integrators to ease onboarding, a practice TTD’s Mike O’Sullivan framed as part of a “spectrum” of duplication. TTD’s PubDesk dashboard (also released last October) is being used by publishers to monitor signals and pacing, though many still want deeper transparency into spend drivers.
