Apple Safari Blocklist Pushes Publishers to Trusted Server
Apple's latest software update has started blocking ad tech companies that track users for targeted advertising in Safari, prompting publishers to urgently revisit IAB Tech Lab's Trusted Server. This server-side solution moves ad auctions from users' devices to publisher-controlled servers, bypassing Apple's blocklist. Publishers like Paradium have already adopted it, while others are evaluating their options. The move highlights Apple's growing control over digital advertising, raising concerns about market power and the impact on publisher revenue. As Apple expands its own ad business, the blocklist underscores the shifting power dynamics in the ad tech ecosystem.

Apple iOS 27 Blocks The Trade Desk from Serving Safari Ads
Apple's iOS 27, released mid-September, 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 dynamic, privately hosted blocklist prevents ad delivery on iPhones, iPads, and macOS, affecting CDPs, DMPs, and DSPs. The Trade Desk's adsrvr.org was removed in iOS 27.2 beta, but Apple plans a broader blocklist covering hundreds of ad tech and martech vendors, disrupting ad serving, attribution, and alternative IDs. Unlike ATT, this fully blocks ad delivery, raising competitive concerns, especially if Google is exempt. Some vendors like LiveIntent and Lotame remain unaffected, but the block reduces publisher demand and shifts market composition. It follows regulatory actions in Europe and a UK class action, with Germany's Bundeskartellamt concluding in mid-2026. IAB Tech Lab's Trusted Server is a proposed solution, but adoption is slow. Impact is currently limited by low iOS 27 adoption but expected to grow.
