San Francisco-based Anthropic is consulting with law firms to establish fair negotiation norms for autonomous AI agents as it places agentic technology at the core of its corporate strategy ahead of a planned IPO. Recent experiments, including a September 2026 book-trading simulation by Anthropic and a Harvard Business School study analyzing over 180,000 negotiations, show that while agents expand access to bargaining expertise, unequal access to superior models risks widening economic disparities.

Experimental negotiation outcomes
