# OpenAI debuts ChatGPT ads at Cannes, CPM plunges > Source: > Published: 2026-06-26 13:25:55+00:00 OpenAI made its Cannes Lions debut this week to pitch **ChatGPT** as an advertising platform, presenting reported early metrics and ambitious revenue forecasts. According to The Next Web, David Dugan said OpenAI has already attracted "thousands of advertisers," and the company projected **$2.5 billion** in ad revenue for **2026**, **$11 billion** for **2027**, and **$100 billion** by **2030**. Early pricing moved quickly: The Next Web reports the pilot launched at a **$60 CPM** and fell to about **$25 CPM** in ten weeks, then shifted to cost-per-click bids between **$3 and $5**, per reporting. Adweek quoted OpenAI chief revenue officer Denise Dresser saying relevancy has improved and called the format "about usefulness."
