Since February 2026, OpenAI has been testing paid ads directly within ChatGPT conversations, gradually adding tools, formats, and features that resemble established advertising platforms such as Google Ads or Meta Ads — just in a completely different environment.

Mergado already supports the official ChatGPT feed format, giving retailers a fast path into this new channel.
