ArcSpan integrates with OpenX to bring publisher first-party audiences directly into programmatic demand. Sep 28, 2026 Publishers can now build audiences in ArcSpan AMS and activate them through OpenX with no additional development work. ArcSpan, the AI-powered audience monetization platform built for premium publishers, today announced a native integration with OpenX, one of the largest independent supply-side platforms. Publishers using ArcSpan AMS can now make their first-party audiences available to buyers on OpenX without a separate custom integration. Publishers have spent years building first-party data. Turning it into programmatic revenue is harder. Segments are often rebuilt for each platform, signals are lost between systems, and buyers can struggle to find and transact on publisher audiences at scale. As a result, much of the value of first-party data never reaches the bid. ArcSpan closes that gap. Publishers use ArcSpan AMS to build first-party, contextual and modelled audiences, understand their composition and commercial value, and now activate them directly on OpenX. First-party data goes from segment to transactable supply in one workflow. What the integration enables Audiences built in ArcSpan AMS can now be activated through OpenX, enabling publishers to: * Push first-party, contextual and modelled audiences into OpenX without recreating segments. * Package audiences as curated deals that buyers can discover and transact on. * Build an audience once and activate it on OpenX alongside other supported destinations, including Google Ad Manager and other SSPs and DSPs. * Extend audiences across display, video and CTV inventory. * See how each first-party audience contributes to delivery, performance and CPM. What it means for publishers Programmatic teams get a faster route from data to revenue. Audiences built for direct campaigns can be made available on programmatic demand the same day, rather than waiting on engineering or rebuilding segments by hand. Commercial teams get clearer proof of value. ArcSpan reports on the delivery, performance and CPM of each audience, so publishers can see which segments earn a premium and focus packaging on them. Publisher groups can package audiences across their titles and domains as a single, more scaled offering, making them more competitive against walled gardens. Availability The integration is live and available to ArcSpan and OpenX customers. Publishers interested in deploying it can contact ArcSpan or OpenX for implementation details.
