OpenAI Starts Testing Ads in ChatGPT

OpenAI has begun testing advertisements inside ChatGPT for logged-in adult users in the U.S. The test, called the “OpenAI Ad Pilot Program,” is limited to users on the free tier and the $8/month ChatGPT Go subscription, while Plus, Pro, Business, Enterprise, and Education plans remain ad-free.

Ads will appear below chatbot responses, clearly labeled as sponsored and visually separated from the AI’s answers. OpenAI says ads will not influence how ChatGPT generates its responses. Answers are still optimized based on what the system deems most helpful to the query. Ad targeting is based on conversation topics, past chats, and prior ad interactions, with advertisers only receiving aggregate performance data like impressions and clicks.

Privacy guardrails are in place: advertisers won’t have access to individual conversations, chat histories, or personal details. Ads won’t be shown to users under 18 or around sensitive topics like health, mental health, or politics. Users can dismiss ads, manage personalization settings, and delete ad data.

Despite a minimum buy-in of $200,000, the pilot has already drawn investment from major agency holding companies, including Omnicom Media, WPP, and Dentsu. Omnicom alone has secured placements for more than 30 clients across apparel, automotive, beauty, CPG, hospitality, retail, QSR, technology, and telecommunications. Early ad mockups from OpenAI have featured scenarios like trip planning, with lodging ads appearing during travel-related conversations.

The move has already prompted competitive positioning from rivals. Anthropic, maker of the Claude chatbot, has highlighted that its product will remain ad-free, including in a recent Super Bowl commercial.

This is a significant shift in how AI platforms monetize. Until now, chatbots like ChatGPT have relied almost entirely on paid subscriptions and API fees to generate revenue, leaving the massive free user base as a cost center. Ads change that equation by monetizing free sessions directly, reaching users at the moment of intent, mid-conversation, mid-decision. It’s the same playbook that built Google and Meta: free product, massive audience, sell the access. Whether that translates into meaningful ROI at a $60 CPM remains to be seen, but the early agency interest suggests the industry is taking it seriously.

For marketers, it opens a new channel where ads reach users at the moment of intent, mid-conversation, mid-decision. Whether that translates into meaningful ROI at a $60 CPM remains to be seen, but the early agency interest suggests the industry is taking it seriously.

It’s too early for most brands to jump in, with a $200,000 minimum buy-in limiting the pilot to major advertisers. But as ChatGPT advertising opens up to clients of all sizes, it’s something we’ll want to test. Chatbots like ChatGPT have already captured a meaningful share of search activity, and where users go, ad dollars tend to follow.
