OpenAI partner StackAdapt sells ChatGPT ads

This looks less like a polished ad launch and more like the first scaffolding of a new intent-based ad market inside ChatGPT. The economics and language around “limited pilot” suggest scarcity, experimentation, and a lot of unanswered questions about measurement.

• –Prompt relevance is a strong targeting signal, but it also raises the hardest ad-tech problems: brand safety, attribution, and whether the placement actually changes outcomes
• –A $15 to $60 CPM band and $50,000 minimum spend point to premium, low-volume inventory rather than a scaled self-serve product
• –StackAdapt is acting as the go-between for OpenAI's ad inventory, which matters because the partner ecosystem is forming before the native ad stack is fully mature
• –For marketers, this is more about learning how conversational intent monetizes than about running a dependable performance channel
