ChatGPT Ad Pilot Hits $100M Revenue in Six Weeks

OpenAI's ChatGPT advertising pilot has reached $100 million in annualized revenue approximately six weeks after its U.S. launch, according to The Information. The company has expanded to more than 600 participating advertisers, though daily ad exposure remains limited and early performance metrics trail industry benchmarks.

How the Revenue Scaled

The $100 million annualized figure is based on conservative ad exposure. According to the report, roughly 85% of free and Go-tier users in the U.S. are eligible to see ads, but fewer than 20% are shown them on any given day. When OpenAI launched ads in January, the company said ads will appear at the bottom of ChatGPT responses, clearly labelled, and OpenAI says they do not influence the chatbot's answers.

Sensor Tower data shows ad impressions increased approximately 600% from early to mid-March 2026. Nearly 80% of small and medium-sized businesses have signalled interest in ChatGPT ads, suggesting demand extends well beyond the enterprise brands in the initial pilot.

“We’re encouraged by early signals from users and participating brands, and continue to see strong interest from advertisers,” OpenAI said.

The Performance Gap

Revenue growth has outpaced advertiser satisfaction. As The Keyword previously reported, the pilot has had a "rocky start." Click-through rates sit at 0.91%, roughly seven times below Google's 6.4% Search benchmark. A reporting glitch in OpenAI's Ad Manager has prevented some advertisers from accessing campaign performance data.

The gap between headline revenue and advertiser experience reflects a pilot that is generating demand faster than it is satisfying advertisers on measurement and performance. The $200,000 minimum commitment and approximately $60 CPM pricing, roughly three times Meta's average rates, set high expectations that the current tooling has not yet met.

International Expansion Begins

OpenAI has begun preliminary ad testing in Canada, Australia, and New Zealand. The U.S. remains the primary market, but the international expansion signals confidence in the revenue trajectory even as domestic execution challenges persist.

New Leadership to Close the Gap

OpenAI recently hired David Dugan, Meta's former VP of Global Clients and Agencies, as VP and Head of Global Ads Solutions. As COO Brad Lightcap has described, the ad rollout is "an iterative process." Dugan's appointment, combined with CEO of Applications Fidji Simo's Meta background, suggests OpenAI is responding to execution challenges by importing the operational expertise that built Meta's $150 billion annual ad business.

What This Means for Advertisers

The $100 million milestone demonstrates market interest in AI-native advertising, but the revenue figure alone does not resolve the pilot's core tension. Advertisers paying premium rates still lack the measurement infrastructure to evaluate ROI. OpenAI says it has observed no measurable impact on privacy-related trust metrics, and ads are restricted from appearing near politics, health, and mental health topics, and are not shown to users under 18.

For brands evaluating the pilot, the question is whether ChatGPT's conversational context delivers value that justifies CPMs well above industry norms, even as the reporting tools catch up.
