Magnite Trials AI Agents on the Sell-Side
Magnite is experimenting with agentic AI on the sell-side by combining traditional ML-based yield optimization with early agent-driven workflows inside its stack, notably within Springserve (its CTV adserver/mediation layer). New capabilities under test include anomaly detection for performance swings, dynamic pricing driven by live signals, and demand-path optimization to prioritise incoming demand sources before auctions. Magnite is also piloting buyer- and seller-agent functions — including a Buyer Agent to support campaign activation and optimization — in joint tests with partners such as Disney Advertising, MiQ and Kepler, and is working with Publicis Media Exchange (PMX) on further sell-side use cases. Projects remain mostly in pilot phases, focused on accelerating operational tasks rather than full automation, and emphasize interoperability with third-party agent solutions.
Magnite is piloting agentic AI and mediation enhancements in the CTV/sell-side stack with notable partners; this could incrementally shift how publishers prioritise demand and automate yield management, but projects are still at pilot stage and not industry‑shifting yet.

Magnite Launches Agentic AI and Smart Mediation
Magnite announced an expansion of AI capabilities for its sell‑side and video mediation products to help media owners and buyers operate more efficiently. Enhancements to the SpringServe video mediation platform include anomaly detection, demand‑path optimization and dynamic pricing. Magnite is also developing agentic AI tools — including a buyer agent — to automate activation, optimization and performance management; Kepler and MiQ are running tests of the buyer agent with inventory from Disney Advertising. Magnite said it will continue to support third‑party agents and is collaborating with Publicis Media Exchange (PMX) and partners such as Spectrum Reach to pilot agentic workflows. Company executives framed the updates as steps toward increased automation, interoperability and faster programmatic execution across premium CTV and other media environments.
Magnite Launches 'Magnite Orchestration' for Agentic Advertising
Magnite announced Magnite Orchestration, a coordination layer that connects buyer agents to Magnite’s seller agent to enable AI-driven, agentic media buying across premium omnichannel inventory. The launch expands Magnite’s buyer and seller agent capabilities and is being tested in beta with partners including dentsu and DIRECTV Advertising. dentsu integrated its dentsu.Audiences segments into Magnite as part of the beta, allowing proprietary audience segments to be surfaced to agentic workflows. Magnite says the platform will let publishers package and expose inventory and audiences for agent-to-agent transactions while enabling buyers to generate media plans, discover supply, and launch omnichannel campaigns (CTV, audio, etc.) via connected buyer agents.
Magnite Unfazed by Agentic AI and Google
Magnite reported Q1 revenue of $164.4 million, up 6% year-over-year, driven largely by connected TV (CTV) where just over half of revenue (ex-TAC) came from CTV. The company highlighted strong live-sports performance (notably 80% YoY growth in March Madness revenue) even as its DV+ exchange declined 5% YoY. Magnite executives — CEO Michael Barrett and CFO David Day — framed the business as well positioned for an increasingly "agentic" programmatic ecosystem, pointing to newly introduced AI tools (mediation in ClearLine and a seller agent in SpringServe) and saying agentic buyer/seller agents should increase platform value rather than replace it. Barrett also expressed optimism about favorable remedies from the Google ad tech trial and reiterated plans to charge for platform services tied to AI-driven functionality.
