Swiss Brands Take Cautious Approach to ChatGPT Advertising
OpenAI has expanded ChatGPT advertising to 31 European markets, including Switzerland, about ten days before this report. However, major Swiss advertisers remain cautious: McDonald's, Aldi and Denner said they do not currently plan to advertise on ChatGPT, while Swisscom, Coop and Migros are still evaluating the formats and pricing. Media agencies confirm strong interest but few concrete booking requests. Omnicom and Havas, both OpenAI partners, note that brand-safety and compliance guidelines must be finalized before budgets move. Experts expect little short-term shift in ad spend, citing Google's strong distribution power and its AI Mode ads. A research institute estimates the US chatbot ad market could reach $5.4 billion by 2030. Agencies see ChatGPT as suitable for performance-oriented, research-heavy categories such as travel, e-commerce and technology, but unsuitable for luxury or B2B campaigns targeting high-income decision-makers, since ads appear only in free and low-cost ChatGPT tiers.
OpenAI expands ChatGPT advertising to 31 European markets, launching a new conversational AI ad channel; while Swiss advertisers are cautious, the rollout signals growing budget shifts toward AI chat interfaces and creates new opportunities and brand-safety challenges.

German Marketers Share Mixed First Experiences with ChatGPT Ads
OpenAI's ChatGPT Ads launched in Germany in late August, allowing advertisers to book via agency partners or a self-serve tool. Early feedback from German marketers is mixed. Dentsu's Markus Caspari sees potential but notes high CPMs and limited reporting. Performance marketer Carlo Siebert reports poor results, with few clicks and conversions, and tracking discrepancies. OpenAI's VP Ads, Dave Dugan, acknowledges the beta stage and promises improvements. Criteo reports CTRs 2-3x higher and 80% new customers, especially effective for consultation-heavy categories.

OpenAI Launches ChatGPT Ads in Germany; EU Rules Differ
OpenAI expanded ChatGPT Ads to 31 European markets (including Germany, France, Switzerland, Italy, Spain, and Austria) plus India, North Africa, and the Middle East, following a US beta test starting in February 2026. The rollout began August 24, 2026. Initially, ads are managed via OpenAI's Ads Solutions team and partner agencies/technology partners, with a self-serve Ads Manager beta expected later in the quarter. Since its May 2026 launch, the platform reached a $1 billion annualized revenue run rate within 200 days. Ads are contextually targeted based on user conversations and appear only for Free and ChatGPT Go tiers (below replies), with paid tiers and minors excluded. Under GDPR, OpenAI uses consent-based models, serving contextual ads to non-consenters. Advertisers can independently book campaigns with CPM/CPC bidding, conversion APIs, and geo-targeting, leveraging a partner ecosystem of over 50 providers. Ads are clearly labeled, separate from responses, and have no access to private conversations. Future plans include additional ad formats and measurement capabilities.
