Permutive and TransUnion Partner to Enhance Sell-Side Curation
Permutive and TransUnion have announced an integration that enables publishers using Permutive's DMP to match their first-party audience data with TransUnion's identity graph and activate TransUnion audiences across Permutive's global publisher network. This addresses the limited addressability of the open internet, where only about 30% of traffic is addressable via cookies or alternative IDs, by leveraging multi-signal identity strategies. Early testing with a financial services advertiser showed a 12x increase in addressable impressions, a 5x increase in consumers reached, and a 170% overshoot of the KPI target. The partnership aims to provide a viable alternative to walled gardens, reduce data fees, and monetize previously unsold inventory, ultimately improving campaign accuracy and performance.
Apple iOS 27 Blocks The Trade Desk from Serving Safari Ads
Apple's iOS 27, released on September 14, has blocked major programmatic data firms, including The Trade Desk, LiveRamp, ID5, Permutive, and Audigent, from serving ads or collecting data in Safari via a WebKit blocklist. This blocklist, dynamically updated via a private GitHub repository, fully prevents ad delivery on affected Apple devices, unlike ATT which only limited cross-app tracking. The block affects iPhone, iPad, and macOS 27.0.1, potentially impacting CDPs, DMPs, and DSPs, while Google might be exempt, raising competitive neutrality concerns. This incident underscores the power imbalance between walled gardens and the open web, reducing publisher demand and shifting market composition. It follows regulatory actions in France, Italy, Germany, and a UK class action over ATT's competitive implications, with Germany's Bundeskartellamt concluding in mid-2026 with Apple making commitments to align its data practices.
