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
