Six weeks. That is how long it took OpenAI to cross $100 million in annualized ad revenue after launching its ChatGPT advertising pilot. Now the company wants those ads to do something Google and Meta never figured out: have a conversation with you.

OpenAI has signed Helsinki-based Smartly as its first creative adtech partner, according to Business Insider. Smartly, led by ad industry veteran Laura Desmond, helps brands like Spotify and Uber optimize ads in real time. Now it will do the same for ChatGPT advertisers. But the real play is bigger: Smartly is building interactive ad formats that mimic ChatGPT itself. Ads that talk back. Ads that ask you follow-up questions. Ads that feel less like interruptions and more like conversations.

Desmond pointed to a proof of concept with UK retailer Boots, where a chatbot ad on Instagram served personalized gift recommendations through a series of questions. That format drove nearly five times the sales of Meta standard ads. Now imagine that inside ChatGPT, where users are already in a conversational mindset, already asking questions, already expecting helpful responses.

Here is the uncomfortable truth: OpenAI swore it would never run ads. Then it started running ads. Then it hired Criteo to place them. Now it is hiring Smartly to make them interactive. The escalation is predictable because it is the only path that works. OpenAI burns $85 billion a year. Subscriptions alone cannot cover that. Ads can.

Evercore ISI analyst Mark Mahaney estimates OpenAI could generate several billion dollars in ad revenue this year and $25 billion by 2030. With more than 600 advertisers already on board and the ad pilot running in free and $8/month tiers only, the runway is enormous. The question is whether users will tolerate it.

This is the moment Anthropic has been waiting for. Dario Amodei promised Anthropic will never run ads. That pledge just became the single clearest differentiator in the AI market. If OpenAI turns ChatGPT into an advertising platform and Anthropic stays clean, the premium user base will migrate. People pay for trust, and trust is hard to maintain when your AI assistant is also your salesperson.

The bigger picture: we are watching the birth of conversational advertising as a category. Not banner ads in a chat window. Ads that participate in the conversation itself. Every major platform will follow. The line between helpful AI and helpful AI that is being paid to recommend a specific product is about to disappear entirely.
