OpenAI has officially announced it will begin testing advertisements in its ChatGPT platform, marking a significant shift in its monetization strategy. The ads will initially roll out for logged-in adult users in the United States, specifically within the free and the newly expanded ChatGPT Go tiers, in the coming weeks. This move aims to diversify OpenAI's revenue streams to cover the exorbitant operational costs associated with running advanced AI services and to maintain broad accessibility to its powerful AI tools. CEO Sam Altman, who previously expressed a strong distaste for traditional internet advertising, has reportedly changed his perspective, citing Instagram as an example of effective advertising where he discovered valuable products. OpenAI emphasizes that these ads will be contextually relevant to the user's conversation, appear clearly labeled below the chatbot's responses, and will not influence the AI's answers. The company has also assured users that their conversations will remain private and not be sold to advertisers. Additionally, ads will not be shown to users under 18 or alongside sensitive topics like health, mental health, or politics. Notably, higher-tier subscribers, including ChatGPT Plus, Pro, Business, and Enterprise, will remain ad-free. The ChatGPT Go plan, which was initially introduced in India in August 2025 and is now available worldwide, is a low-cost subscription tier that will incorporate these advertisements. This development positions OpenAI's business model closer to that of other tech giants like Google and Meta, which heavily rely on advertising revenue.
