In January 2026, OpenAI formalized the arrival of advertising on ChatGPT, marking a major turning point in the digital advertising landscape. With 400 million weekly active users and a market projected at $26 billion by 2029, this new advertising channel is redefining the rules established over 20 years by Search Ads.
This 36-page white paper provides an in-depth analysis of the transition from Search Ads to Conversational Ads. You'll find a detailed structural comparison of both models, an analysis of OpenAI's 5 principles and their implications for advertisers, as well as a decision framework for determining your strategic posture: Early Mover, Fast Follower, or Strategic Observer.
Written by Jordan Chenevier-Truchet, CEO of Bulldozer, this document relies exclusively on confirmed announcements, verified market data, and established advertising principles. No hype, only facts and actionable recommendations.
