Criteo Stock Rises After Expanding ChatGPT Advertising Integration With OpenAI – Criteo (NASDAQ: CRTO) shares rose 3% on Tuesday after the company announced an expanded integration with OpenAI’s ChatGPT advertising platform.
The advertising technology company reported that more than 1,000 brands are now running campaigns through its ChatGPT integration, including both existing Criteo clients and new advertisers. The expansion comes as OpenAI rolls out self-serve advertising for ChatGPT, broadening access to conversational AI-powered advertising.
Criteo became the first advertising technology partner to integrate with OpenAI’s pilot advertising program for ChatGPT in March 2026. The company is now widening access through Criteo GO, its self-service platform designed for small and medium-sized businesses.
This integration has also expanded into international markets, including Australia, Canada, and New Zealand. According to Criteo, budgets allocated to ChatGPT advertising are incremental, with marketers treating the platform as an additional discovery channel rather than shifting spend away from existing advertising channels.
The company reported that click-through rates (CTR) on ChatGPT ads are approximately three times higher than similar formats in other environments. Conversion rates for users referred from ChatGPT are nearly double those of traditional search in categories such as consumer electronics, lifestyle and wellness, and home and garden.
Criteo also highlighted strong adoption from both holding companies and independent agencies eager to test conversational AI within their existing media planning workflows. The company has partnered with brands such as Foot Locker Asia Pacific, HP, and Petbarn as part of the pilot program.
Looking ahead, Criteo said its focus remains on preserving user experience, integrating AI-powered media into its cross-channel advertising platform, and deepening its partnership with OpenAI.
