Markets are competitive if and only if P ≠ NP

This analysis summarizes key insights from the paper "Markets are competitive if and only if P ≠ NP" by Philip Z. Maymin, exploring the profound implications for enterprise AI strategy and market dynamics.

Executive Impact: AI & Market Dynamics

This paper establishes a fundamental connection between computational complexity and market structure, proving that competitive market outcomes are sustained by computational limitations. If P=NP, firms can efficiently detect and punish deviations, making collusion sustainable. If P≠NP, and the collusion detection problem is computationally hard, competition prevails. This implies a 'Efficiency–Competition Impossibility': markets cannot be simultaneously informationally efficient and competitive. The rise of AI, by expanding firms' computational capabilities, is pushing markets from competitive to collusive regimes, posing a challenge to traditional antitrust policy. The paper proposes 'computational antitrust' as a new approach.

The paper argues that competition persists because firms lack the computational power to sustain collusion. If P=NP, collusion becomes sustainable; if P≠NP, competition prevails in complex markets.

A key finding is the 'Efficiency–Competition Impossibility': markets cannot be both informationally efficient (P=NP) and competitive (P≠NP) simultaneously.

AI systems expand computational capabilities, moving markets from competitive to collusive regimes. This explains the empirical emergence of algorithmic collusion without explicit coordination.

Increased market transparency, conventionally seen as pro-competitive, actually facilitates collusion by reducing the computational cost of deviation detection.

Impact of P vs. NP on Market Outcomes
Scenario Market Efficiency Market Competition
If P = NP ✓ (Efficient) ✗ (Collusive)
If P ≠ NP ✗ (Inefficient) ✓ (Competitive)

Algorithmic Collusion in Practice

Recent empirical evidence, such as studies on German gasoline markets and financial markets, shows that AI-powered pricing algorithms and large language models autonomously converge to supra-competitive pricing. This occurs without explicit communication, driven purely by enhanced computational capabilities to detect and sustain collusive strategies. This shift represents a 'computational phase transition' from competitive to collusive equilibrium.

Takeaway: AI transforms collusion from intent-based to capability-based.
