“Not only are we doing the match to enable scale for audience targeting based on the amazing shopper data and bringing it to Disney, we’re also enabling that same scale to provide accuracy in measurement,” Power said.

Walmart’s purchase data will be synced with Disney’s Audience Graph using clean-room technology—which allows entities to combine datasets in a privacy-protected way—in a private marketplace. That will give advertisers more flexibility and clearer sales attribution, according to Disney.

It’s also the first time Disney has used shopper data in streaming, using programmatic and biddable technology to identify audience matches. For example, Power said advertisers could target audiences based on lapsed consumers or those open to switching brands.

“Approximately 145 million customers shop with us online and in stores weekly,” Ryan Mayward, senior vp of retail media sales for Walmart Connect, said in a statement. “Now, marketers will be able to apply those insights to their full-funnel campaigns to reach customers wherever they’re streaming Disney content.”

The new targeting capabilities will be available within Disney to a small group of advertisers spanning categories including consumer packaged goods, consumer electronics, telecommunications, auto, apparel and beauty this quarter, rolling out more broadly in the next couple of months.

“Retailers partnering with streaming services and CTV platforms are now part and parcel of retail media networks as they look to target the opportunity created by the fall in linear TV viewership—and to cope with the capabilities of Amazon in TV,” Colin Lewis, director of Retail Media Works, told ADWEEK. “The combination of Disney’s content depth and breadth alongside the reach and scale of Walmart’s audiences and their total omnichannel purchase data means that Walmart will have the most robust streaming choices for advertisers.”
