TL;DR: Agent-to-agent deal governance is the set of rules, records, and oversight mechanisms that ensure AI agents on both sides of a media transaction operate within authorised boundaries and produce auditable outcomes.

The Problem Governance Solves

When two AI agents negotiate a media deal, each acting on behalf of a different organisation, several questions arise immediately. Who authorised each agent to make this deal? Are the agreed terms within both parties' mandates? Where is the deal record held? Who can inspect it, and under what conditions? What happens if one party disputes the terms later?

Traditional programmatic infrastructure was not built to answer these questions. It was built for automated execution at scale, with human-configured campaigns and a supply chain that handled reconciliation imperfectly at best. Agent-to-agent transactions require something more explicit: a governance layer that sits above the execution layer.

That governance layer is what deal governance provides.

The Components of Deal Governance

The deal record. A governed deal requires a shared, durable record of what was agreed. This record captures the terms: price, volume, targeting parameters, delivery windows, brand safety constraints, and any conditions that modify the base agreement. Both the buying agent and the selling agent should hold a copy of this record, and those copies must be consistent.

In Alkimi's model, this function is served by the DealSheet. It is a bilateral record mechanism that allows both parties to hold the same deal data without requiring a direct API integration between their respective systems. The marketplace holds the canonical record; both sides reference it.

The approvals workflow. Not every deal should be executed automatically. Governance defines which deal types and value thresholds require human approval before the agent can proceed. A well-designed approvals workflow routes the right decisions to the right people in a timely way without blocking routine transactions.

The mandate layer. Each agent operates within a mandate that defines its scope of authority. Deal governance verifies that the agreed terms fall within both mandates before the deal is considered valid. If an agent accepts terms outside its mandate, the governance layer should surface that as an exception requiring human review.

Audit logs. Every negotiation, offer, counter-offer, acceptance, and rejection should be recorded in a tamper-resistant audit log. These logs serve multiple purposes. They support post-campaign reconciliation. They provide evidence in the event of a dispute. They also allow teams to review agent behaviour and refine mandates over time.

How Standards Support Governance

Two emerging standards are relevant to deal governance in agentic advertising.

The Agent Communication Protocol (AdCP), published by AgenticAdvertising.org, defines how agents communicate during negotiation. It specifies the message formats and interaction patterns that allow a buying agent and a selling agent to exchange offers and reach agreement in a structured, verifiable way.

The Agentic Advertising Marketplace Protocol (AAMP), published by IAB Tech Lab, addresses how agents interact with marketplace infrastructure. Together, these standards create the conditions for interoperable deal governance across different technology stacks.

Governance built on open standards is more durable than governance built on proprietary interfaces. It allows organisations to switch vendors, adopt new tools, and participate in multiple marketplaces without rebuilding their governance infrastructure each time.

Human Oversight in Agent-to-Agent Deals

A common misconception is that agent-to-agent deal governance means humans are removed from the process. The opposite is true. Effective governance makes human oversight more meaningful, not less frequent.

Without governance, humans are often reviewing outputs after the fact: checking invoices, reconciling discrepancies, investigating complaints. With governance, human review happens at the right points in the process. Humans approve mandate expansions. They sign off on high-value committed deals. They review escalation events. They examine audit logs to understand agent behaviour patterns.

The goal is not to remove human judgement. It is to focus human judgement where it creates the most value and to give agents clear authority for the decisions they are well-positioned to make.

Why Governance Is a Competitive Requirement

For US buyers and sellers considering agentic advertising, governance is not optional. Enterprise procurement teams, legal departments, and finance functions will require it before they permit agent-led transactions at meaningful scale.

Building governance into agentic advertising from the start is significantly easier than retrofitting it after agents are already executing transactions. The organisations that establish clear deal governance frameworks now will be better positioned as agent-to-agent trading becomes a standard part of the media buying workflow.

Agent-to-agent deal governance is the infrastructure that makes automated trust possible.
