Approximately 3% of Polymarket traders earn more than 30% of total profits, while the majority loses money on the platform.

Study findings

Researchers report that 67% of platform users operate at a loss and effectively subsidize the profits earned by a small group of traders.

About 3% of traders capture more than 30% of total profits on the market, indicating concentrated earnings among a minority of participants.

Interpretation of results

Authors conclude that observed market outcomes reflect decisions of an informed minority rather than the crowd's aggregated wisdom in this platform context.

The study cautions against interpreting Polymarket prices as collective intelligence signals without accounting for information concentration and strategic trading behavior.

Implications for users

Retail participants should be aware that their losses may finance a minority that systematically extracts value through superior information or execution on the market.

Greater transparency in trade flows and account-level performance data could be necessary to assess whether prices reflect distributed probabilities or concentrated strategic activity.

Methodology and scope

The analysis examined profit and loss distributions across accounts and calculated aggregate profit shares to identify concentration among top-performing traders on Polymarket.

Overall, the findings highlight asymmetric profitability on the platform and recommend careful interpretation of market prices when estimating collective judgment.
