Walmart Connect and Magnite are making retail media and CTV convergence real. See how 150M customers, Vizio inventory, and programmatic supply come together. Retail media and connected TV have been on a collision course for years.

Walmart Connect and Magnite are building it. At Cannes Lions 2026, AdExchanger Editorial Director Sarah Sluis sat down with Mike Laband, Group SVP of Revenue at Magnite, and Khurrum Malik, VP of Marketing at Walmart Connect, to talk about their partnership, what it enables for advertisers, and what it represents for the broader trajectory of commerce-driven advertising.
