AI Spurs AdTech Alliances; Social Video Outgrows CTV

AdExchanger’s roundup highlights how agentic AI is driving unexpected partnerships across the ad-tech stack — from The Trade Desk embedding its DSP through Pacvue and Skai to Yahoo integrating its DSP workspace into Kochava’s StationOne — enabling shared agentic workflows and reducing duplicated tooling. The IAB projects U.S. digital video ad spend will surpass $80 billion in 2026, with social video ad spend growing ~13% year-over-year versus an ~11% gain for CTV, driven by AI personalization and clearer performance attribution on social platforms (YouTube is classified as social video alongside Instagram and Reddit). The piece also notes over 1,200 consumer-facing ChatGPT/Claude integrations with major brands, but early adoption is low due to discoverability constraints. Additional items: FTC/Media Matters settlement, Meta’s use of “AI bone structure analysis,” Viant’s close of TVision acquisition, and several industry hires including NextRoll’s new CTO.

German Federal Court Hears Cookie Storage Liability Case

Germany's Federal Court of Justice (BGH) is hearing a case on whether a technology and analytics company is liable for storing cookies on users' devices without consent on third-party websites. The plaintiff seeks damages, with lower courts awarding €1,500 and then €100. The case centers on the interpretation of the TDDDG. A ruling is not expected immediately. Legal experts say a BGH confirmation of the lower court's view would require companies to implement technical and organizational measures beyond contractual assurances to prevent unauthorized cookie placement. Meanwhile, the EU Commission proposed in November 2025 to reduce cookie banner pop-ups by allowing users to store preferences on their devices. The proposal faces scrutiny in the European Parliament and Council, with consumer advocates concerned about member states' resistance.

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.
