ChatGPT Now Runs Ads in Four Countries, Hit $100M Revenue, and the AI World Is Split

$100 million in annualized ad revenue within six weeks. OpenAI has proven that monetizing AI conversations is viable, and the industry is taking sides.

ChatGPT ads go international in April 2026

OpenAI began testing ads on February 9, 2026, for adult users on the Free and Go tiers in the U.S. As of April 17, sponsored placements now also appear in Canada, Australia, and New Zealand.

The format is simple: a labeled “Sponsored” block at the bottom of a ChatGPT response, visually separated from the AI-generated answer. OpenAI insists ads never influence responses. Plus, Pro, Business, Enterprise, and Education subscribers see no ads at all.

ChatGPT advertising: the numbers so far

By March 26, OpenAI disclosed it had hit $100 million in annualized revenue from the ad pilot in just six weeks. Over 600 advertisers have joined, including Target, Ford, and Adobe. WPP, Omnicom, and Dentsu are all launch partners.

CPMs dropped from $60 at launch to $15-40 depending on category. The minimum spend fell from $200,000 to $50,000, and self-serve ad tools are rolling out this month. That means smaller brands can finally get in.

Anthropic’s counter-move: no ads in Claude, ever

Anthropic wasted no time. In February, the company ran a satirical Super Bowl campaign with the tagline: “Ads are coming to AI. But not to Claude.” The company says it will fund Claude through enterprise contracts and subscriptions only, a model it shares with its latest Opus releases.

Sam Altman fired back, calling the ads “clearly dishonest.” His argument: ads keep ChatGPT free for 900 million weekly users. Anthropic counters that users shouldn’t second-guess whether an AI is helping them or steering them toward something monetizable. Both sides have a point.

What this means for you

If you use ChatGPT without paying, you’ll see discreet contextual ads tied to your conversation topic. You can turn off personalization, dismiss any ad, or delete your ad data anytime. Perplexity, Microsoft Copilot, and even Google are all exploring similar formats: conversational advertising is becoming the norm.

The real challenge? Click-through rates sit at 0.91%, far below Google Search’s 6.4% benchmark. ChatGPT still needs to prove its value to advertisers. But with 900 million weekly users actively researching and comparing options, the intent signal is gold. This story is just getting started.
