Operators should note that ad performance on the platform has shown strong momentum, with click-through rates more than doubling between late March and early September 2026. OpenAI is leveraging targeted placement based on specific user conversations to maximize engagement.

Business software ads captured 20% of impressions, while Jotform utilized 930 distinct ad variations in a single month. These efforts contribute to OpenAI's reported annual run-rate revenue of $1 billion.
