OpenAI claims ChatGPT Ads reached $1 billion annualized revenue run rate in under 200 days

MarTech analyzes OpenAI's announcement that ChatGPT Ads has reached a $1 billion annualized revenue run rate, supported by a streamlined 60-second campaign builder and $500 matching credits for new advertisers. The company projects explosive growth—$11 billion in 2027, $25 billion in 2028, and $100 billion by 2030—but MarTech notes these forecasts lack independent verification and face significant skepticism from research firms like eMarketer, which expects the entire U.S. standalone chatbot advertising market to generate less than $1 billion in 2026. Early performance results remain mixed, and the core challenge remains unproven: whether ChatGPT can sustain advertiser spending and profitability at scale without compromising user trust.
