Polymarket: Contract Design, Trading Volume, and Dispute Risk
A near-census study of over 800,000 resolved Polymarket contracts found that information available at listing—especially market topic—strongly predicts trading volume and can signal dispute risk at settlement. The findings are relevant to prediction-market design, governance, and regulatory considerations as the sector grows.

## Overview
A large-scale empirical study analyzed 802,863 resolved markets listed on Polymarket between January 2023 and May 2026, examining what information available at listing—title, description, named resolution source, and contract metadata—predicts lifetime trading volume and the likelihood of settlement disputes (arXiv:2610.29578, October 22).
## Key Findings
The study found that contract information strongly predicts trading volume, achieving an out-of-sample R² of 0.747 for log volume, with market topic contributing the largest gain (+0.289 R² over a 0.220 contract-feature baseline) (arXiv:2610.29578, October 22). The research also examined wording and other contract-design factors as predictors of dispute risk at settlement.
## Strategic Importance
Polymarket has become a significant prediction-market platform whose contract design, resolution mechanisms, and dispute patterns carry implications for market integrity, regulatory scrutiny, and the broader prediction-market industry. As prediction markets gain mainstream and institutional attention, understanding what drives trading volume and disputes is relevant to platform design, regulatory engagement, and legal risk assessment for market operators and participants.
