OpenAI Launched a Self-Serve Ads Manager for ChatGPT. The $50K Minimum Is Gone.

OpenAI is no longer just an AI company. As of May 5, it is an advertising platform.

ChatGPT Ads Manager is now open to all US businesses. The previous $50,000 minimum spend that kept the pilot exclusive to enterprise advertisers is gone. Any business can create a campaign, set a cost-per-click bid and run ads inside ChatGPT conversations.

The platform supports CPC bidding, a Conversions API for tracking post-click actions like purchases and sign-ups, and pixel-based measurement. Advertisers can buy directly or through agency partners including Dentsu, Omnicom, Publicis and WPP. Ad tech companies like Adobe, Criteo, Kargo, Pacvue and StackAdapt are also integrated.

This is the first credible challenger to Google's dominance in intent-based advertising. ChatGPT conversations carry high purchase intent. Users ask specific questions about products, services and decisions. That context is valuable for advertisers in ways that generic display inventory is not.

The self-serve model also lowers the barrier dramatically. During the pilot phase, only enterprise brands with six-figure budgets could test the platform. Now a small business in Melbourne could theoretically run a campaign, though geographic availability is currently US-only. OpenAI confirmed expansion to the UK, Japan, South Korea, Brazil and Mexico in the coming weeks. Australia is not on that list yet, but it was included in the earlier ChatGPT Ads pilot.

The competitive pressure this puts on Google is significant. If ChatGPT ads deliver strong conversion rates at reasonable CPCs, advertisers will split budget away from Search. Google has already responded by accelerating its own AI ad products through Meridian and AI-powered bidding.

For Australian marketers, this is a watch-and-wait moment. The platform is not available here yet. But when it arrives, the businesses that have already thought about their AI search strategy will be the ones who move fastest.

The fact that OpenAI removed the spending floor tells you everything about their growth strategy. They want scale, not exclusivity.
