Criteo, the global commerce media platform, has announced it is the first advertising technology partner to integrate with OpenAI's advertising pilot in the free and Go versions of ChatGPT in the United States.

  • Criteo integrates as the first ad tech partner in OpenAI's ChatGPT advertising pilot for U.S. free and Go users.
  • Aggregated data from Criteo's U.S. clients shows users from LLM platforms like ChatGPT convert at about 1.5 times the rate of other referral channels.
  • The pilot evaluates how brands can advertise thoughtfully in conversational AI to drive incremental demand to retailers and brand destinations.
  • Criteo leverages its commerce intelligence and AI-driven decisioning to activate over $4 billion in annual media spend across 17,000 global advertisers.
  • Integration supports high-intent advertising in emerging AI surfaces, connecting brands, retailers, and publishers for cross-channel outcomes.
  • Rollout begins in the coming weeks as part of OpenAI's ongoing ChatGPT advertising pilot.

This partnership positions Criteo at the forefront of shaping advertising in large language model (LLM) environments. By activating commerce media in conversational discovery, Criteo helps brands reach high-intent users at moments of active consideration, driving measurable performance back to e-commerce destinations.

High-Intent Traffic from Conversational AI Insights from Criteo's U.S. client base highlight the strong conversion potential of traffic originating from LLM platforms. Users engaging through ChatGPT demonstrate elevated purchase intent compared to traditional referral sources, underscoring the value of relevant advertising in these AI-powered interactions.

Advancing Trusted and Additive Advertising "This integration with OpenAI represents an exciting step forward in advancing advertising in an emerging AI experience," said Michael Komasinski, Chief Executive Officer of Criteo. "Through this pilot, we are helping shape how advertising can support discovery and consideration within Large Language Model (LLM) platforms, grounded in experiences that are additive, relevant, and built on user trust."

Criteo's scale—managing billions in media spend and partnering with thousands of advertisers—enables it to bring commerce expertise to this new channel. The integration ensures advertising remains commerce-oriented, supporting a broad range of categories while contributing to incremental growth for brands and retailers.

The rollout of the Criteo integration within OpenAI's advertising pilot is expected to begin in the coming weeks, allowing brands to test and refine their presence in ChatGPT's conversational ecosystem.
