OpenAI US ChatGPT ads hit $100M in six weeks—what changed?

OpenAI’s U.S. ChatGPT advertising pilot reportedly crossed $100 million in annualized revenue within six weeks and expanded to 600+ advertisers, with plans to introduce self-serve access in April.

That matters because it signals that OpenAI has found a comparatively fast monetization channel beyond subscriptions. Instead of relying solely on consumers paying for access, the company is turning ChatGPT into an advertising surface—an approach that can scale quickly if marketers can target and budget effectively.

What the update suggests

• Advertiser demand is building quickly. Growing to hundreds of advertisers in a matter of weeks implies teams are finding practical use cases for ChatGPT-based placements.
• Self-serve onboarding is the next unlock. Moving to self-serve tends to lower friction for smaller advertisers and can increase total spend by widening access.
• Ad revenue becomes a stabilizer. In a market where AI model costs are significant and product roadmaps can change, advertising can provide steadier cash flow.

Why it’s newsworthy now

The story pool also includes OpenAI decisions to pause or cancel certain side initiatives, indicating prioritization. Against that background, the ads pilot looks like a deliberate effort to focus on revenue-generating distribution. If the ramp continues after self-serve launch, it could reshape how companies budget for conversational AI marketing and how platforms measure performance in ad campaigns.
