TL;DR

OpenAI has begun testing advertisements in ChatGPT for free and low-cost subscription users in the United States. Premium subscribers will not see ads, and the company insists ads will not influence ChatGPT’s responses.

A revenue shift

The test targets logged-in adult users on ChatGPT’s free tier and the $8-per-month Go subscription plan. Only a small percentage of ChatGPT’s nearly one billion users pay for premium subscriptions, which will remain ad-free.

OpenAI said it would keep user conversations private from advertisers and that ads would not affect the chatbot’s answers. But the move marks a notable shift for CEO Sam Altman, who had previously expressed a dislike for advertising, citing concerns it could create distrust in ChatGPT’s content.

Competitive sparring

The decision comes as OpenAI burns through cash at a rate driven by the computing power needed to run its services. The company’s valuation has reached $500 billion in funding rounds, with some analysts expecting a future IPO at a trillion-dollar valuation.

Rival Anthropic took the opportunity to position itself against the move, debuting its first Super Bowl advertisement. The ad featured a man receiving earnest advice from a chatbot before the conversation veered into a pitch for a fictional dating site — a pointed contrast promoting Claude as ad-free.

Looking forward

Advertising in AI chatbots represents a new frontier with significant implications. If users begin to question whether responses are influenced by commercial interests, it could undermine the trust that has driven ChatGPT’s rapid adoption. How OpenAI balances revenue needs against user confidence will shape the broader debate about AI business models.
