Two-thirds of consumer attention lives on the open internet, but only one-fifth of ad spend follows it there. That gap is no accident. Walled gardens spent the past decade creating it.
But now the gap is about to close. Better data, real investment in AI, credible measurement and market consolidation are giving the open internet the tools to finally prove that it can compete with walled gardens on outcomes, not just reach.
Open internet publishers collectively reach audiences at a scale that exceeds any closed platform. Fragmented technology stacks, point solutions and limited visibility into outcomes, however, have made it structurally difficult for open internet players to connect the right advertiser with the right audience. Inventory that is fragmented or cannot demonstrate its value attracts less demand, which results in lower CPMs.
