StackAdapt and OpenAI Pilot Ads in ChatGPT

StackAdapt is quietly recruiting advertisers for a pilot program that places ads within ChatGPT. The demand-side platform is offering $15 CPMs to brands willing to test the AI's effectiveness as a product discovery tool. This partnership signals OpenAI's growing interest in establishing a structured advertising ecosystem.

Key Points

• StackAdapt is partnering with OpenAI to enable a limited pilot for ads inside ChatGPT.
• The program offers low $15 CPMs and reduced fees to attract early-stage advertisers.
• ChatGPT is being positioned as a 'discovery layer' for users in the middle of product research.
• The move represents a significant step in the monetization and commercialization of generative AI platforms.

Sentiment

The community is overwhelmingly negative about ChatGPT ads. Most commenters view this as an inevitable but disappointing development that will erode trust in LLM outputs. There is strong cynicism toward OpenAI's leadership and broken promises, with many drawing unfavorable parallels to Google's trajectory. While a minority sees this as a reasonable business decision, the dominant sentiment treats it as confirmation that OpenAI has abandoned its original mission in favor of short-term revenue.

In Agreement

• Users share first-hand experiences of ChatGPT already failing at product discovery with hallucinated items and dead links, suggesting the ad infrastructure is premature
• Ad industry professionals note that partnering with a third-party DSP is a common bootstrapping strategy for proving market value before building in-house
• Prompt-based ad targeting captures high-intent moments during product research, representing a potentially valuable advertising surface
• The move follows the standard tech monetization playbook of establishing user dependency before introducing advertising

Opposed

• Using prompt data for ad targeting contradicts OpenAI's earlier public statements about not sharing prompt information with advertisers
• Unlike Google, OpenAI lacks a monopoly — competitors like Anthropic and open-source models give users viable alternatives if ads degrade the experience
• Ad-influenced outputs could fundamentally undermine trust in LLM responses, which is far more damaging than search engine ad placement since users treat LLM outputs as authoritative advice
• Partnering with a third-party DSP is a strategic blunder for a company with ChatGPT's scale; every major ad platform above $1B in revenue operates their own ad sales
• This is a sign of revenue desperation rather than strategic innovation, as OpenAI struggles to meet lofty investor expectations
