The Accountability Question
As transaction volume between fully autonomous buyer and seller agents has grown, the open question regulators are starting to focus on is not the technology itself but accountability: when a transaction between two AI systems, acting without real-time human instruction, produces a disputed or fraudulent outcome, whose liability framework applies.
Early Regulatory Signals
Rather than new agent-specific rules, early regulatory moves have mostly involved applying existing consumer-protection and payment-processing frameworks to agent-initiated transactions, with regulators explicitly stating that acting through an autonomous agent does not remove the principal's existing obligations.
Practical Implication for Platforms
For marketplace platforms hosting agent-to-agent transactions, the safest posture is treating an agent's action as legally equivalent to the human or entity that issued its credentials — meaning audit trails tying every agent action back to an accountable principal are becoming a compliance necessity, not an optional feature.
