MUMBAI: The advertising middleman is getting a digital makeover and this time, the negotiators might be algorithms. Magnite is betting that the future of media buying will be less about humans clicking through dashboards and more about AI agents striking deals on their behalf. The independent sell-side advertising company has unveiled Magnite Orchestration, a new coordination layer designed to connect AI-powered buyer agents with Magnite’s seller agent, enabling automated transactions across what the company describes as one of the industry’s largest pools of premium advertising inventory.
The launch reflects a broader shift across digital advertising, where artificial intelligence is increasingly moving beyond campaign optimisation into the mechanics of planning, negotiating and activating media buys.
At the heart of the platform is the ability for AI-driven systems to discover, evaluate and activate advertising inventory across channels within a shared environment. Buyers, publishers and data providers can also make proprietary audience segments available to participating agents, allowing audience data and premium inventory to be packaged together more seamlessly.
As part of early testing, media agency network dentsu has integrated its dentsu.Audiences segments into the ecosystem, enabling proprietary audience insights to surface automatically when relevant to campaign requirements.
Magnite has also expanded its buyer and seller agent capabilities to automate key parts of the advertising workflow.
Through the Magnite Seller Agent, publishers can create custom inventory and audience packages, apply pricing and targeting controls, and make their inventory discoverable to buyer agents, paving the way for agent-to-agent transactions.
On the demand side, buyers can either connect their own AI agents through Magnite’s open integrations or use the Magnite Buyer Agent to generate media plans from a simple request for proposal (RFP), identify relevant inventory and audience opportunities, and launch omnichannel campaigns across connected TV home screens, audio environments and other premium formats.
The development comes as advertisers and media owners search for ways to simplify an increasingly fragmented ecosystem. Rather than relying on multiple platforms and manual workflows, the industry is exploring whether AI agents can act as autonomous operators capable of handling much of the transaction process.
For Magnite, the objective is to position itself as the infrastructure layer connecting those systems.
The company is already testing the platform with partners including dentsu and Direc TV Advertising, signalling growing interest in agentic AI as the next frontier of advertising automation.
The move also highlights how the competitive battleground in adtech is shifting. The conversation is no longer limited to programmatic buying or audience targeting; it is increasingly centred on which platforms can become the operating system for AI-powered media transactions.
If that vision takes hold, tomorrow’s media deals may be negotiated less in boardrooms and more between algorithms working behind the scenes at machine speed.
