Do you trust automated AI agents to handle media buying processes effectively?
The IAB Tech Lab has released AAMP 3.0, a framework designed to standardize the Request for Proposal process for agentic advertising. This update introduces the OpenProposal specification, which enables buying agents to automatically interpret and evaluate media opportunities.
Why it matters
Current manual media buying workflows create significant friction in agentic processes, as AI agents lack a unified way to negotiate and compare proposals before execution. Standardizing these exchanges allows for faster, more accurate deal-making between buyers and sellers.
The IAB Tech Lab has released AAMP 3.0, updating its framework to bridge the gap between initial RFPs and final buy commitments. The impact of these standards currently hinges on the ongoing pilot testing being conducted by IAB Australia.
The players
IAB Tech Lab
An international non-profit consortium that develops technical standards and protocols for the digital advertising industry.
IAB Australia
The Australian division of the industry body currently conducting seller-side pilot testing for AAMP reference implementations.
The details
OpenProposal defines a machine-readable format for sellers to present advertising products and for buyers to submit briefs. By integrating with existing standards like AdCOM, OpenDirect, and the Deals API, the spec ensures agents can discover and compare opportunities seamlessly. It also utilizes idempotency to prevent duplicated requests during agent retries, reducing errors in automated transactions.
Timeline

Market Landscape
AAMP 3.0 follows a long-standing industry trend of developing unified technical languages, such as the IAB Tech Lab's AdCOM protocol, to reduce friction in digital media markets. By formalizing machine-readable proposals, the industry is moving toward fully automated negotiation cycles.
Operators in the advertising supply chain should prepare to integrate the OpenProposal specification into their agent SDKs to maintain compatibility with emerging buying tools. Reviewing current RFP automation capabilities against the AAMP 3.0 framework will be critical for future-proofing.
The takeaway
Standardizing agent-readable proposals is a necessary shift to reduce the manual overhead of digital media buying. Operators should monitor the public comment period ending October 22, 2026, to influence how these automation standards are shaped for their specific ad product sets.
