IAB Overhauls Multi-State Privacy Agreement to Streamline Compliance for Digital Advertisers
Event summary
- IAB updated its Multi-State Privacy Agreement (MSPA) on March 4, 2026, marking the most significant revision since 2023.
- The update aims to simplify compliance, reduce contracting friction, and strengthen protections under U.S. state privacy laws.
- Key changes include streamlined structures, clearer roles for ad tech partners, and operational simplicity for consumer opt-outs.

The big picture

The IAB's move to standardize privacy terms aims to create a shared compliance foundation, reducing the need for custom contract amendments and repeated negotiations. This aligns with broader industry efforts to simplify compliance across a growing patchwork of state privacy laws.
