OpenAI’s ChatGPT Ads Hit $1 Billion Revenue Run Rate in Under 200 Days

OpenAI’s bet on advertising is paying off far sooner than many expected. ChatGPT Ads has reached a $1 billion annualized revenue run rate in less than 200 days after launch, giving the AI giant another major revenue stream as it lays the groundwork for a potential blockbuster IPO.

The milestone is striking for its speed. OpenAI began testing ads inside ChatGPT in the U.S. in February. Roughly six months later, tens of thousands of advertisers are using the platform, according to the company, and ChatGPT Ads are available in more than 40 countries.

“In less than 200 days after launch, ChatGPT Ads has reached $1 billion in annualized revenue run rate. The platform is now used by tens of thousands of advertisers and continues to expand globally. Starting later today, advertisers can purchase ChatGPT ads directly via Ads Manager across India, Europe, the Middle East, and North Africa,” OpenAI said in a statement.

The figure is an annualized run rate, rather than $1 billion already collected over the past year. Still, reaching that pace so soon gives investors what they’ve been waiting to see: evidence that ChatGPT can generate substantial revenue beyond paid subscriptions, enterprise contracts, and API usage.

That matters more as OpenAI moves closer to a possible IPO. The company was valued at $852 billion following its March funding round, setting an enormous bar for future growth. Advertising gives OpenAI another way to monetize ChatGPT’s huge consumer audience without requiring every user to pay a subscription.

ChatGPT now has more than 1 billion weekly active users, according to OpenAI. Ads appear on its free tier and for Go subscribers, putting advertisers in front of a consumer audience few digital platforms have ever assembled this quickly.

OpenAI is building an ad business Google and Meta can’t ignore

Digital advertising has been dominated by Google and Meta for years, whose businesses benefit from billions of users and enormous amounts of commercial activity. ChatGPT introduces something different: people increasingly use AI assistants to research products, compare choices and make decisions through conversations rather than traditional search queries or social feeds.

That could make placing an ad inside an AI conversation unusually valuable. It could also make the format unusually sensitive.

OpenAI says ads are clearly labeled and do not influence ChatGPT’s answers. The company says advertisers cannot access users’ private conversations, an important distinction for a product where people routinely share information they would never type into a public social network.

The decision to introduce advertising has already drawn criticism. Anthropic, one of OpenAI’s biggest rivals, mocked the strategy in its first Super Bowl advertising campaign, positioning Claude as an AI assistant without ads.

OpenAI appears willing to make the opposite bet.

“Advertising is one pillar of OpenAI’s diversified business model, alongside consumer subscriptions, enterprise offerings, and usage-based APIs. Together, these offerings give people, developers, and businesses choice in how they access OpenAI products, including an advertising-supported free tier that helps keep ChatGPT available to more than 1 billion weekly active users.”

The company is now opening self-service ad buying across India, Europe, the Middle East and North Africa. OpenAI says more markets, ad formats, campaign objectives and measurement tools are coming.

The bigger question is what happens when advertising moves deeper into AI conversations.

Google built one of history’s most profitable businesses around ads placed next to human intent expressed through search. Meta built another around ads matched to people’s interests and social behavior. OpenAI now sits in front of something potentially just as valuable: hundreds of millions of people telling an AI assistant, in their own words, what they want.

At a $1 billion run rate in less than 200 days, advertisers are already paying to join that conversation.
