Emarketer acquired the research business of RetailX, a UK retail events and intelligence company, for undisclosed terms, bringing over its research team, tools, and rankings. Emarketer will now publish RetailX’s UK500, which ranks Britain’s 500 biggest ecommerce retailers, and its pan-European CustomerX Index, which launches in late September, and plans new US editions that add data from its recently launched AI Visibility Index for tracking how brands show up in LLM search. RetailX’s events business stays independent and will run a media partnership with Emarketer.
