DMEXCO returned to Cologne on September 23-24 under the official theme “Scaling Intelligence.” The message behind the theme was straightforward: AI has moved beyond experimentation, and the industry is now being asked to prove where it creates measurable operational and business value.
That idea was visible across the conference program and the exhibition floor. But AI was only part of the story.
Across conversations about programmatic advertising, CTV, retail media, digital out-of-home, commerce, identity, and measurement, another pattern became increasingly clear: advertising technology is becoming more connected.
Publishers are monetizing more types of inventory. Retailers are extending media businesses from websites into stores. Streaming platforms need advertising that works inside live and on-demand video. DOOH is becoming more programmatic. Advertisers want measurement across all of these environments.
The question for Adtech is therefore changing from “How do we support another channel?” to “How do we manage all these channels without creating another fragmented technology stack?”
Here are five trends we took away from DMEXCO 2026.
1. AI Has Moved from Feature to Infrastructure
AI was everywhere at DMEXCO, but the conversation felt different from the first wave of generative AI adoption.
The official DMEXCO theme, Scaling Intelligence, focused on moving AI from pilots and isolated use cases into business processes, operating models, and measurable value creation. DMEXCO described the shift as moving from experimentation toward tangible operational impact.
The same direction was visible on the show floor. In the LinkedIn and attendee coverage reviewed after the event, b.telligent and Entirely discussed AI orchestration across marketing technology stacks, while Magnific positioned generative AI as production infrastructure for creative teams. At the same time, closing-day commentary from attendees including Damien Dubois reflected growing skepticism toward adding AI for its own sake and emphasized the continued role of proprietary data, judgment, and human creativity. This tension matters for Adtech.
The next phase is unlikely to be defined by how many AI features a platform can list. The more useful question is where AI can remove operational friction: campaign setup, optimization, forecasting, inventory management, creative workflows, reporting, and decision-making.
AI is becoming part of the infrastructure rather than the headline itself.
That also means the quality of the data, workflows, and systems underneath AI matters more. If those foundations are fragmented, adding another intelligent layer does not automatically make the stack more efficient.
2. Programmatic is More Privacy-Safe and More Contextual
Programmatic remained one of DMEXCO’s core conversations, but the data layer continues to evolve.
The DMEXCO Adtech Summit placed first-party data, contextual targeting, identity solutions, supply-chain transparency, curated marketplaces, and connected TV among the central topics reshaping the advertising ecosystem.
The same themes appeared in exhibitor and attendee communication. DeviceAtlas highlighted privacy-safe, non-PII device intelligence without fingerprinting, while Seedtag promoted contextual AI designed to understand interest and intent without relying on personal data. The broader evolution of the industry from programmatic scaling and header bidding toward privacy-first frameworks, omnichannel integration, and AI-driven workflows.
The important point is that the market is no longer discussing privacy only as a replacement problem for third-party cookies. The broader question is how to maintain addressability, relevance, optimization, and measurement while relying less on personally identifiable data.
That pushes programmatic infrastructure toward a combination of:
- first-party data;
- contextual and environmental signals;
- privacy-safe identity approaches;
- direct publisher relationships;
- transparent supply paths;
- interoperable measurement.
Programmatic is not becoming less important in a privacy-first environment. It is becoming more selective about which data, inventory, and signals create real value.
3. Media Convergence is Pushing Adtech Toward Full-Stack Infrastructure
One of the clearest trends at DMEXCO was not a single channel or technology. It was convergence.
DMEXCO’s own 2026 coverage described a media market where traditional channel boundaries matter less: retail media is extending beyond digital storefronts, CTV is combining reach with addressability, DOOH is increasingly programmatic, and data and AI are changing how campaigns are optimized and measured. The event’s World of Media overview explicitly framed the challenge as choosing and managing the right combination of channels, data, and formats.
For technology providers, that creates an infrastructure problem. A publisher may need display, video, native, audio, and video ad streaming monetization. A media company may need SSP, DSP, and ad server workflows. A retailer may operate sponsored products on-site, programmatic campaigns off-site, and digital screens inside physical stores. A sales house or agency may need to manage campaigns across several of these environments.
Building another independent platform for every channel eventually recreates the fragmentation the industry is trying to remove. This is the thinking behind the concept we brought to DMEXCO 2026:
One Platform. Every Media.
For Adtelligent, it means approaching ad serving as an ecosystem rather than a collection of disconnected channels:
Programmatic Ad Server → Connected Ad Exchange → Dynamic Ad Insertion → Retail Media → DOOH CMS
Our SSP and DSP infrastructure supports programmatic supply and demand across formats and devices. Dynamic Ad Insertion connects advertising with video and audio streams. The Adtelligent Retail Media Platform extends monetization across on-site, off-site, and in-store inventory. DOOH CMS brings digital screens into the same broader advertising environment.
The objective is not to force every media type into an identical workflow. It is to make it possible for publishers, media companies, sales houses, agencies, retailers, and advertisers to monetize, manage, deliver, and measure advertising across increasingly connected media environments without rebuilding the technology stack for every new channel.
The trend is broader than Adtelligent. DMEXCO organized dedicated summits around adtech, DOOH, Retail & Commerce Media, MarTech, Commerce, and related disciplines, while its own event coverage repeatedly highlighted the overlaps between them. DMEXCO’s 2026 overview of its event worlds noted that AI, retail media, cookieless targeting, CTV, streaming, attribution, and platform strategy increasingly cut across previously separate areas of the market.
That is why interoperability is becoming a product requirement, not just an integration feature.
4. CTV Is Becoming “Total Video”
CTV remained highly visible at DMEXCO, but the conversation continues to mature.
The Future TV program brought together connected TV, streaming, addressable television, and broader total-video discussions. DMEXCO’s official event materials positioned CTV and streaming as part of an increasingly connected media mix rather than as isolated emerging formats.
The attendee review reflected the same shift. Goldvertise and Azerion shared findings from their CTV research around how viewers choose and consume connected television, while discussions around attention suggested that the next optimization question is moving beyond whether an ad can technically be delivered toward whether the impression actually earns attention.
This changes the infrastructure requirements behind video advertising.
Streaming services need to combine content delivery and monetization without damaging the viewing experience. Technologies such as Server-Side Ad Insertion (SSAI) and Dynamic Ad Insertion (DAI) make it possible to integrate advertising into live and on-demand streams while supporting addressability and programmatic demand.
The bigger trend, therefore, is not simply “more CTV.” It is the development of a total-video advertising ecosystem in which streaming, live content, programmatic buying, ad serving, and measurement increasingly need to work together.
5. Retail Media Is Moving Beyond the Website
Retail media was another major theme at DMEXCO 2026, and one development stood out in particular: the physical store is becoming part of the media network.
The DMEXCO Retail & Commerce Media Summit described retail and commerce media as moving from experimental channels into core marketing infrastructure. The program emphasized scalable retail media networks, first-party data, closed-loop measurement, transparency, and the blurring of boundaries between retail, media, marketplaces, connected stores, and commerce platforms.
DMEXCO’s broader media coverage made the convergence even more explicit: on-site, off-site, and in-store channels are converging, and retailers are expanding their media offerings across the customer journey.
The show-floor review supported the same conclusion. xplace positioned digital signage as part of a seamless shopping experience connecting physical displays with digital platforms, while the Retail Media Alliance highlighted cross-retailer approaches to in-store measurement.
This reflects the evolution we are also seeing in our own product development.
Retail media used to be strongly associated with sponsored products, search placements, and display ads on retailer-owned websites. Those formats remain important, but the model is expanding into:
- on-site inventory;
- off-site programmatic activation;
- social and video channels;
- in-store digital screens;
- indoor and outdoor DOOH;
- measurement tied more closely to shopper and sales outcomes.
A digital screen inside a store is therefore no longer only a signage endpoint. It can become managed advertising inventory.
That is where Retail Media and DOOH begin to overlap. A retailer needs to manage content, screens, campaign delivery, device status, scheduling, and monetization while connecting those operations with the broader media business.
As we explored in our article on in-store media and DOOH CMS, the CMS becomes the operational layer that allows screen-based media to scale across many locations while remaining controllable and measurable.
What DMEXCO Tells Us About the Next Stage of Adtech
DMEXCO 2026 did not point toward one dominant advertising channel. Almost the opposite. There are more media surfaces, more data signals, more buying models, and more ways to reach audiences than before. The challenge is managing that complexity.
AI can automate more of the workflow. Privacy-safe data can maintain relevance without recreating old tracking models. Programmatic is extending into streaming, retail, and DOOH. Retail media is connecting digital commerce with physical stores.
But every one of these developments adds pressure to the infrastructure underneath them. That is why interoperability, omnichannel management, and full-stack ad serving are becoming as important as individual channel innovation.
The strongest technology stacks will not necessarily be the ones that add another standalone solution for every new format. They will be the ones capable of connecting inventory, demand, campaign management, delivery, and measurement across the media environments advertisers and audiences already use. For us, that was one of the clearest messages from Cologne.
One Platform. Every Media.
Not because every advertising channel is becoming the same, but because managing them as completely separate ecosystems is becoming increasingly difficult.
