OpenAI builds ChatGPT ad category at Cannes

Business Insider conducted an onstage interview with OpenAI Head of Global Ads Solutions David Dugan at the 73rd Cannes Lions International Festival of Creativity, where OpenAI presented its ChatGPT advertising offering, Business Insider reports. Per Semafor, ChatGPT's ad product launched in February for free and "Go" tier users and displays ads within queries and conversations. Semafor reports the company already has thousands of advertisers across seven test markets, and that it said it plans launches in Brazil and Mexico in the coming weeks and eventual expansion into India. Semafor further quotes Dugan: "The revenue that we make from the ads offering is going to subsidize and grow access to information." AdExchanger headlined coverage with the quote "We are clearly in the advertising business now," and Marketing Dive characterizes OpenAI's pitch as a move toward an "intelligence economy" aimed at "super intentional" users.

Chat-based ad inventory differs from conventional attention-driven formats because it is anchored in user intent expressed as conversational queries. Industry-pattern observations: advertisers moving into conversational surfaces typically rely more on session and query signals than on traditional third-party audience segments; measurement tends to shift away from view-based metrics toward engagement and conversion signals tied to dialogue outcomes. For practitioners, that implies increased emphasis on prompt-aware creative, shorter feedback loops for creative testing, and instrumentation that links conversational context to downstream metrics.

Semafor reports OpenAI set an audacious revenue target of $100 billion from advertising by the end of the decade, which the article notes is roughly half of current Meta ad revenue. Industry observers at Cannes framed OpenAI's entry as an attempt to create a distinct ad category rather than directly copy feed or search models, per Marketing Dive and AdExchanger. Industry-pattern observations: when major platform owners introduce new ad inventory, buyer adoption depends on three things-measurement clarity, predictable performance, and the ability to port creative or IP. Historical examples show advertisers will test new inventory quickly if early measurement and attribution are usable.

• •Expansion cadence: Semafor reports near-term launches in Brazil and Mexico followed by India; market additions will be a primary adoption signal.
• •Advertiser mix and scale: monitor growth beyond the "thousands" of early advertisers reported by Semafor and whether larger brand dollars follow.
• •Measurement and attribution: whether third-party and in-house measurement firms produce repeatable metrics for chat-native outcomes.
• •User experience: reported click-away frequency trends and any public metrics OpenAI shares about ad frequency and engagement.

Industry-pattern observations: conversational ad formats privilege intent and dialogue flow over passive reach, which tends to favor advertisers who can adapt creative to short, context-aware interactions and invest in rapid measurement experimentation.
