Agentic Ad Budgets Are Live. Access Them With Your Storefront.

Buyer agents are managing advertising budgets on behalf of the world’s top brands and agencies. The marketing leaders guiding them have moved from evaluating agentic advertising capabilities last year to executing live campaigns at scale.

For any seller or service provider — whether a surface owner, a data provider, a creative platform, or a governance partner — this shift has a direct consequence: if buyer agents can’t find you and your offering, spend will flow elsewhere.

Enter agentic storefronts. Sellers who’ve opened their Storefront are already winning budgets run directly by brands (and their agents) on Interchange, where the world’s leading marketers are executing agentic advertising. Murph, Scope3’s AI concierge, guides sellers through each setup and readiness step.

How brands and agencies are transforming their marketing and advertising with AI agents

Brands are now using AI agents across their marketing and advertising efforts, including for disciplines like customer service, commerce, content, personalization, and more. Agentic AI is quickly becoming the primary vehicle they use to reach and engage consumers, and the numbers bear that out.

Gartner projects that 60% of brands will use agentic AI to deliver one-to-one marketing interactions by 2028, describing it as “the end of channel-based marketing as we know it.” Morgan Stanley estimates that AI agents could influence $190B to $385B in U.S. e-commerce spending by 2030, representing 10 to 20% of the total online retail market.

Media buying is following the same trajectory. The IAB’s 2026 Outlook Study finds that 66% of ad buyers are increasing focus on agentic AI for ad buying and campaign execution, with 96% already aware of it as an active capability. Ad buying has moved from a trailing use case to a leading one, and surface owners are responding as a result.

CNN has built in-house agent infrastructure. Disney unveiled an “Ads Agent” that generates full media plans from creative briefs. NBC has deployed AI agents over live sports inventory on linear television. Netflix announced a suite of AI agents that can manage, optimize, and purchase ads on the platform autonomously.

Underpinning this broader momentum is the rise of shared standards. Chief among them is the Ad Context Protocol (AdCP), an open standard that lets AI agents discover, negotiate, and transact media across any surface. AgenticAdvertising.org is the industry body behind it.

How today’s media buying infrastructure leaves premium seller value on the table

Surface owners and service providers have built valuable assets: deeply engaged audiences, premium inventory, proprietary data, and creative capabilities that brands can’t replicate on their own. The commercial challenge has always been how to effectively connect these assets to the buyers best positioned to use them.

Legacy buying infrastructure was built around the impression and the CPM. That works for standard inventory but struggles with the products and pricing models that often define a premium offering — such as a homepage takeover priced per day, a custom sponsorship built around a live event, or a multi-surface content series sold as a package.

Direct sales can carry that depth, but only when deal size justifies the overhead. Brief review, product selection, pricing negotiation, and creative trafficking can take five to ten business days minimum. Sellers regularly miss campaigns that would have been a strong fit simply because the economics of getting the deal done don’t pencil out on either side.

The result is a persistent gap. Campaigns that would perform exceptionally well against a seller’s best assets consistently fail to find them. Closing it means giving sellers a way to put forward the full picture of what they offer and have buyers evaluate it on its merits. That is exactly what agent-to-agent advertising makes possible.

How agent-to-agent advertising prioritizes strategic fit and why that changes everything for sellers

Agent-to-agent advertising changes the terms of competition, prioritizing fit over price alone. A buyer agent’s job is to find the best match for a brief. Sellers who represent their offerings through agents, with the clarity, depth, and full context of what they provide, are well-positioned to secure budgets.

Consider a DTC athleisure brand launching a new performance line. Its buyer agent sends a structured query to Interchange to evaluate offerings from live Storefronts.

• A lifestyle media brand responds with premium editorial placements and sponsored content, substantiated by first-party data.
• A premium CTV network responds with pre-roll and mid-roll inventory tied to sports, fitness, and wellness contexts.
• A social platform surfaces sponsored content and creator placement packages.
• A creative partner recommends on-brand performance creative adapted to each format.
• A third-party signals provider responds with fitness and active lifestyle segments.

The agent evaluates every response and recommends a portfolio allocation based on what will work best for the campaign rather than on price alone. A marketer reviews the recommendation, adjusts where needed, and approves the buys before anything goes live.

How your Storefront helps you merchandise, sell, and scale revenue on Interchange

Your agentic storefront is a structured hub that holds everything you offer — your surfaces, audiences, packages, pricing, and terms — and serves as your commercial presence on Interchange. It’s how you become discoverable to buyer agents representing leading brands and agencies.

Each Storefront comes with a merchandising agent that you can custom-train to reflect how you sell. Murph, Scope3’s AI concierge, works through this with you, drawing on your existing media kits, rate cards, and assets.

• Represent your full value. Express brand prestige, audience profile, contextual quality, and creative specs alongside inventory.

The buyer agents running campaigns today on Interchange are building familiarity with the surfaces and services they can find, the sellers whose agents respond well, and the Storefronts that deliver. That familiarity becomes preference, and preference compounds into commercial advantage.
