      ChatGPT Ads expanded to Spain in August 2026, and OpenAI confirmed self-service Ads Manager availability across its new European markets on August 31. The platform now supports campaign creation, conversion optimization, geo-targeting, the OpenAI Pixel and Conversions API.

      For companies searching for ChatGPT Ads agencies in Madrid, location is only one consideration. Current OpenAI campaign guidance centers European targeting at country level, while more detailed sub-country targeting is explicitly available in the United States, so this guide considers agencies with Madrid offices alongside Spanish and European specialists that can manage campaigns for Madrid-based advertisers.

        Omnicom Media Spain has a substantial Madrid presence alongside its Barcelona operation. For larger advertisers, the appeal is less about a standalone ChatGPT Ads package and more about incorporating the channel into a broader media strategy managed by an international agency network.

The agency also works across international PPC, SEO, paid social and B2B demand generation.

        Its European office is in Barcelona, and the company works across multiple international markets and languages. This makes COSEOM a useful option for Madrid-based B2B businesses whose campaigns need to extend beyond Spain rather than remain purely domestic.

        The agency is based in Barcelona, but its wider paid media operation explicitly serves companies across Spain, including Madrid. ChatGPT Ads can also be integrated with Google Ads, Meta, LinkedIn and TikTok rather than managed as an isolated advertising channel.

        Conclusion

        ChatGPT Ads is still a relatively new advertising channel, which makes agency selection especially dependent on practical platform experience, measurement capabilities, and the ability to connect campaigns with existing paid media activity. Madrid businesses can choose from local specialists, Spanish performance agencies, and global media groups with direct access to OpenAI’s advertising ecosystem.

        The right provider will depend on campaign scale and wider marketing needs. Smaller and mid-sized companies may prefer agencies that combine ChatGPT Ads with PPC, GEO, landing pages, and conversion tracking, while larger brands may need broader media planning and international campaign management. Comparing each agency’s service scope, Madrid coverage, reporting approach, and experience with conversational advertising can help narrow the list to the most suitable option.
