Four-Layer Architecture
A framework for understanding AI-mediated markets as four interdependent layers: Representation, Reasoning, Action, and Governance.
Description
The Four-Layer Architecture provides a macro-structure for understanding AI-mediated markets. The Representation Layer encodes market-relevant information. The Reasoning Layer processes information for decision-making. The Action Layer executes transactions. The Governance Layer ensures safety, fairness, and accountability. Each layer has specific requirements, failure modes, and design considerations.

The Emerging Architecture of AI-Mediated Markets
The Emerging Architecture of AI-Mediated Markets proposes a conceptual framework for understanding how AI systems participate in economic markets as intermediaries, reasoning agents, and action coordinators. The framework identifies four distinct layers—Representation, Reasoning, Action, and Governance—that must work together for AI-mediated markets to function safely and efficiently. Each layer has specific requirements, failure modes, and design considerations. The Representation Layer encodes market-relevant information in machine-readable form. The Reasoning Layer processes this information to support decision-making. The Action Layer executes market transactions with appropriate constraints. The Governance Layer ensures safety, fairness, and accountability. This framework synthesizes insights from property markets, hospitality, and other domains to propose general architecture principles applicable to any AI-mediated market.
Cognitive Market Infrastructure
The transition from platform-mediated to AI-mediated markets represents not merely a technological shift but a fundamental restructuring of market coordination infrastructure. When AI systems become the primary coordinators of market activity—reconstructing entities, reasoning across representations, comparing opportunities, validating trust, negotiating constraints, coordinating actions, routing decisions, and orchestrating transactions—markets become reasoning systems. This paper introduces Cognitive Market Infrastructure as the foundational framework for understanding how AI systems reconstruct, compare, coordinate, and transact through machine-readable representations. We argue that AI-mediated markets function as cognitive coordination infrastructure—systems that reason on representations rather than display interfaces, reconstruct entities rather than retrieve documents, coordinate through protocols rather than platforms, and orchestrate transactions through autonomous coordination stacks.
AI-Native Market Structure
The transition from platform-mediated to AI-mediated markets represents not merely a technological shift but a fundamental restructuring of market coordination, competition, liquidity, and economic power. This paper introduces AI-Native Market Structure as a distinct market formation category—structurally different from both traditional physical markets and platform-mediated digital markets. We argue that AI-mediated markets are not digitized platform markets but fundamentally different economic structures with different coordination primitives, competition dynamics, infrastructure layers, switching costs, and concentration mechanisms. When AI systems mediate discovery, comparison, trust evaluation, reasoning, and transaction coordination, market structure reorganizes around machine-readable representation and cognitive interoperability rather than traffic aggregation and interface control.
