ChatGPT ads and AI advertising influence

The gist

ChatGPT Ads Hit $1B Annualized Run Rate; Unit Economics Undisclosed

OpenAI built a significant advertising revenue stream alongside its subscription and enterprise business in under 200 days. Whether that ad business is profitable at the free-tier level remains an open question.

The full picture

OpenAI's ChatGPT advertising business reached a $1 billion annualized revenue run rate in fewer than 200 days after launch, with tens of thousands of advertisers across more than 40 countries. The product lets businesses run campaigns inside ChatGPT at moments when users compare options and make decisions. Whether serving free-tier users is profitable has not been disclosed. In India, sponsored units appear below relevant answers for both free ChatGPT users and paid ChatGPT Go subscribers. The targeting system draws on the current conversation and, for personalized ads, past chats and memory, without exposing those records to advertisers. OpenAI states advertisers cannot influence ChatGPT responses or access users' chats, memories, or personal details. Anthropic is taking a contrasting approach, keeping Claude ad-free and focusing on enterprise and paid subscriptions.

A Stanford research paper the same day finds a payola problem in agentic AI: companies may bid to shape product recommendations without user knowledge, with healthcare and finance identified as especially serious domains; government disclosure requirements could help, the paper states, though enforcement may be difficult.
