Retail media consolidation and incrementality scrutiny predicted
At the Advertising Club of New York's Commerce Media Exchange, Jason Colon of Horizon Commerce argued that the retail media landscape is facing a period of consolidation due to fragmentation and increased scrutiny from advertisers. He stated that the 'golden era of attribution' is over and that advertisers now demand proof of incrementality. Colon believes that not every retailer needs its own media network, and that many smaller networks lack differentiation. He predicts a 'forced consolidation' in the sector and emphasizes that commerce media should be integrated into holistic media strategies rather than being siloed. He also suggests that the distinction between retail media and general media will eventually disappear as data-driven commerce capabilities become standard practice.

OpenAI tests ChatGPT ads that link to brand agents instead of websites
OpenAI is testing a new ad format in ChatGPT where clicking an ad opens a conversation with a brand's AI agent within the chat interface, rather than redirecting to the advertiser's website. This shifts the advertising funnel from a click to a conversation. The format is being tested with companies like Wayfair, who confirmed participation. OpenAI has not commented. The ads are labeled and OpenAI states advertisers cannot influence chatbot responses or access user data, only aggregated performance data. This development could change how brands engage consumers and how ad success is measured, focusing on conversation quality rather than clicks.
- OpenAI is testing a 'click-to-chat' ad format that opens a conversation with a brand's AI agent in ChatGPT.
- The new format replaces traditional website landing pages with chatbot dialogues.
- Ads are available in 31 European markets, including Germany.
