Criteo sees early traction in OpenAI ad pilot as self-serve ads roll out

Criteo (CRTO) provided an update on the company’s integration with OpenAI. “In March 2026, we announced our integration with OpenAI’s advertising pilot in ChatGPT, becoming the first advertising technology partner to integrate. Criteo was selected because of our ability to bring immediate scaled demand, global market reach, and a proven platform that marketers already use across channels. That combination made it possible to move quickly while keeping activation familiar for marketers and operationally simple across platforms. Today, OpenAI is expanding that vision with the launch of self-service ads, a meaningful step forward for the ecosystem that makes conversational AI accessible to more marketers… While we’re still in the early stages of this partnership, momentum is building quickly,” the company said. “As the pilot program continues to evolve, our focus remains on three priorities: keeping the user experience central, making AI-native media additive for marketers, and continuing to learn and scale responsibly.”
