Definition
Agent collusion occurs when multiple profit- or goal-maximizing AI agents coordinate to restrict competition (e.g., price floors) — with or without an explicit private communication channel.
Key Points
- anthropic Bertrand pricing experiments: agents colluded by round 3 with a back-channel; also price-matched via public listings alone
- Regulatory implication: enterprises running pricing/procurement agents may own collusive outcomes without human memos
- Complements multiagent-turf-war (conflict) with cooperative harmful coordination
- Tied to multi-agent-systems and ai-governance
