Enabling buyers to test and scale AI-native advertising for the first time
The way people interact with information online is changing. As billions of consumer interactions now take place inside generative
PubMatic and Kontext are partnering to ensure that this next phase of digital engagement evolves within the open internet ecosystem — with the same transparency, accountability, and publisher participation that define programmatic advertising today.
Kontext provides a monetization layer for gen AI content experiences, enabling publishers to safely expose their content to large-language-model (LLM) environments and conversational interfaces while maintaining control, attribution, and revenue. Their platform focuses on structured publisher content ingestion (rather than scraping), context + intent-based ad placement inside AI-generated answers, and direct transparency back to the publisher.
Through this partnership, PubMatic becomes Kontext’s first SSP integration, connecting AI-native ad experiences to scaled programmatic demand while preserving the standards of quality, transparency, and brand safety that underpin the open internet.
Why Chatbots Are the Next Frontier
Generative AI represents a transformative platform shift, comparable to the transitions from desktop to app and from linear to connected TV. As conversational interfaces become a core part of how people shop, learn, and explore, advertising models must adapt to where user attention is moving. AI interactions are personalized, contextual, and conclusive. Users ask specific questions and receive synthesized answers. That means advertising in these environments must be equally intelligent, contextual, and commerce-driven.
By integrating with PubMatic’s infrastructure, Kontext provides the connective tissue that allows these experiences to enhance the open internet, extending programmatic standards and monetization models into the AI era.
Chatbots rank among the top emerging channels marketers want to explore; in a 2025 global survey, 97% of businesses said they plan to use AI in customer communications, with 43% specifically naming
As this behavior scales, the opportunity for brands to reach and engage consumers in conversational environments grows rapidly — yet, until now, few have had a practical programmatic path to test or buy this inventory.
How the Integration Works
As a pioneer of the first real-time ad generation framework for LLM-based interfaces, Kontext’s technology dynamically creates and serves contextually-relevant text-based ad messages. Rather than relying on static creatives, each ad is generated on the fly to match the flow of conversation, ensuring contextual alignment, brand safety, and seamless integration. By placing messages within highly relevant conversational moments, Kontext enables advertisers to appear when users are actively exploring related topics, products, and decisions.
By integrating Kontext’s AI-native ad generation with PubMatic’s AI-first infrastructure, capable of processing trillions of auction decisions daily at near-zero latency, this partnership lays the foundation for advertisers to access AI chatbot inventory through familiar programmatic workflows and apply the same data, targeting, and measurement capabilities they use across the open internet.
Key highlights:
- Launching with curated private marketplace (PMP) 1-to-1 deals for initial testing, with plans to expand to PubMatic open exchange and additional PMP packages as the integration matures.
- Supports contextual and data-driven targeting through initial DSP integrations and direct activation via PubMatic’s Activate, with additional platforms and enhancements coming soon.
- Enterprise-grade transparency and brand safety controls, powered by Kontext’s AI technology and aligned with PubMatic’s global publisher standards.
- Sub-millisecond decisioning speed enabled by PubMatic’s AI-first, accelerated computing infrastructure.
Early Performance Indicators
Initial pilot campaigns powered by Kontext, and now being prepared for scaled testing on PubMatic, have shown strong engagement and efficiency. In a campaign executed with Liquid Advertising, Kontext delivered exceptional results, including 70% higher ROAS than the client’s target, a 1.5x stronger click-to-convert rate compared to other platforms, and high-quality engagement driven by contextually relevant ad placements aligned to players’ in-chat queries.
These results highlight the advantage of serving ads in conversational moments where users are actively seeking related information — and where intent is strongest.
Across Gen AI publishers, Kontext’s platform has increased average revenue per user by 66% compared with control cohorts using traditional monetization, proof that AI-native ad experiences can add meaningful economic value.
