OpenAI has activated cost-per-click pricing for ChatGPT advertising, letting marketers bid $3–$5 per click via the company's ads manager, per Digiday. The shift from impression-based pricing — CPM launched at $60/thousand ten weeks ago before falling to $25 — targets performance-focused advertisers who currently dominate spending on Google and Meta. The move signals OpenAI is treating advertising as a structural revenue line rather than an experiment.
