OpenAI's ad business hits $1B run rate ahead of expected IPO

What's the deal? OpenAI said Monday its advertising business has reached $1 billion in annualized revenue run rate, a milestone the company is touting as proof of its "diversified business model" ahead of an expected IPO. The ad unit is roughly 200 days old.

Why now? OpenAI is gearing up for what is expected to be a massive public offering, and is under pressure to justify its $852 billion valuation to investors. The ad revenue milestone builds on existing engines like enterprise offerings, consumer subscriptions, and usage-based APIs.

The numbers: Ads within the ChatGPT chatbot appear for OpenAI's Go subscribers and its free tier, which makes up the vast majority of its 1 billion weekly active users. OpenAI began testing ads in the US in February.

The product: ChatGPT Ads are now available in more than 40 countries. OpenAI said its ads are clearly labelled and do not influence ChatGPT's answers, and advertisers cannot access users' private conversations.

Expanding where? On Monday, OpenAI began rolling out self-service access across India, Europe, the Middle East, and North Africa. "Our next phase of growth will bring ChatGPT Ads to more markets and introduce additional formats, objectives, buying options, and measurement capabilities," the company said.

What could go wrong? The move into ads was both highly anticipated and controversial. Rival Anthropic ridiculed the push, making it the focus of its first Super Bowl campaign.

The signal: Digital advertising has long been the cash cow for big tech companies like Google and Meta. OpenAI's pivot into that market signals it wants a proven revenue stream to underpin its valuation as it moves toward going public.
