Polymarket Trader Outcomes, Risk Responses, and Topic Specialization
Summary
The report examines trading and settlement records from Polymarket’s international platform to describe account profitability, responses after wins and losses, position risk, and specialization by market topic. It excludes accounts placing more than 50 orders per active day as likely automated, then treats remaining wallet addresses as retail accounts. Profit includes positions that settled at a gain even if they were not redeemed, avoiding the omission of unclaimed losses.
The analysis finds most included accounts lost money overall, while automated accounts collectively profited. Accounts were more likely to stop trading after a loss, though wallet changes could make apparent churn misleading. After controlling for entry-price bands, winners more often increased position size, and post-win positions were somewhat more likely to carry higher expected downside. Results also vary by topic: sports specialists performed poorly, while specialists in several other areas did better than generalists. The report is descriptive rather than causal; wallet addresses may not map one-to-one to people, the automation cutoff is a judgment call, and some topic groups are small.
Key ideas
- The analysis removes high-frequency accounts using an orders-per-active-day cutoff, but the threshold is a judgment call.
- Most human-paced accounts lost money, while the aggregate automated-account result was positive.
- Losses were followed by more apparent trading churn than wins, though traders could have switched wallets.
- Comparisons of position sizing after wins and losses need to account for entry price.
- Topic concentration had mixed results, with performance differing substantially across specialties.
