SovereignNegotiation-Bench: Evaluating User-Owned Personal Agents In Delegated Bargaining Under Privacy, Consent, Evidence, And Institutional Pressure

The advent of personal AI agents capable of negotiating on behalf of individuals for various transactions, from refunds to sales, necessitates a robust framework for evaluating their performance beyond mere deal completion. A new benchmark, SovereignNegotiation-Bench, has been developed to assess these AI agents against five key duties derived from agency law: loyalty, obedience to actual authority, confidentiality, candor, and diligence. This benchmark includes 1,764 paired negotiation scenarios across 18 consumer and peer-to-peer domains, designed to operationalize these legal duties as deterministic checks.

The increasing delegation of negotiation tasks to AI agents presents both opportunities and risks. Establishing clear benchmarks and regulatory frameworks is critical to ensure these agents operate ethically, legally, and in the best interest of their principals, thereby maintaining trust and mitigating potential liabilities. This development underpins the foundational trust mechanisms required for widespread AI adoption in sensitive financial and personal dealings.

Personal AI agents are increasingly performing delegated negotiation tasks for individuals.
