Stagwell launches Curate inventory marketplace
Stagwell has launched Stagwell Curate, an inventory marketplace aimed at giving the agency holding company more control over where client media dollars flow. Matt Adams, global CEO of Stagwell Media Platform, told Digiday the offering is not intended to replace existing ad tech like DSPs but to improve execution within programmatic inventory. The article frames the move as part of a broader tug-of-war: DSPs, SSPs and agency holdcos are all vying to replicate parts of the programmatic supply chain, with consolidation in the middle layer expected as AI and new technologies reshape how inventory is curated and sold.
An agency holding company launching its own inventory marketplace signals continued agency moves into ad tech and could accelerate consolidation and changes in the middle layer of the programmatic supply chain, affecting publishers, DSPs and SSPs.

Stagwell launches AI media curation marketplace
Stagwell is building and set to launch 'Stagwell Curate', an AI-driven media curation platform that aggregates curated CTV, online video, display and audio inventory from publishers and adtech partners into a central reservoir. The system uses AI agents (built with Claude) and data from The Trade Desk’s OpenSincera to perform a "domain health check" that evaluates ad- and supply-chain quality and web technical performance, then assembles bespoke inventory packages for clients. Stagwell says the platform aims to reduce reliance on third‑party DSP/SSP marketplace tooling, lower tech fees, increase transparency and speed for media buyers, while still using DSPs to execute bids. The effort leverages publisher relationships with Magnite and Freewheel and follows other agency and holding-company moves to bring curation upstream.
Google Antitrust Ruling Spares Ad Stack, Pressures Trade Desk
A federal judge ruled that Google must open up its ad exchange and publisher ad server to more competition but stopped short of forcing a breakup of its adtech stack. The remedies include connecting AdX and DFP to Prebid, requiring equal terms for AdX bids on alternative servers, curbing self-preferencing, and sharing auction data. For The Trade Desk, which has positioned itself as the neutral alternative to Google's walled gardens, this outcome weakens its core pitch: a fairer and more transparent auction reduces the urgency for publishers to seek alternatives like OpenPath. The article also notes that Google's decision to keep third-party cookies has already slowed adoption of alternative IDs like UID2.0. Analysts suggest The Trade Desk's narrative is shifting towards CTV and agentic advertising as the open-web competition with Google evolves.
