When Two AI Agents Talk: A Gap in Detection Capabilities

This article turns to a detection problem that computational methods are unusually well placed to solve. Where seller-side algorithmic collusion leaves public price signals that agencies can audit, AI agents bargaining with one another on behalf of their principals — over a single remaining airline seat, say — can converge on cartel-like outcomes through private, unrecorded, and possibly non-human-legible exchanges, leaving no trace on which traditional enforcement can build.
