Polymarket revamps exchange after fee hikes and integrity concerns

Polymarket, a decentralized prediction market exchange, announced a redesign of its trading platform in a company statement, citing user feedback and outside scrutiny. The firm said the package of changes aims to clarify fees, strengthen surveillance and improve how markets are created and settled.

The announcement follows complaints from active traders and liquidity providers about recent fee increases. Users reported that higher costs reduced market liquidity and made frequent trading uneconomical. Some market outcomes also attracted questions about abnormal trading patterns and whether trades reflected fair competition.

Polymarket plans to revise its fee schedule to make charges and the conditions for applying them clearer to users. The company intends to update the user interface to show price formation and a more detailed fee breakdown, add expanded trade histories and disclose liquidity-provider incentives so participants can see costs and rewards more clearly.

The platform will deploy upgraded surveillance tools designed to detect patterns consistent with wash trading, insider trading or coordinated manipulation. The company described a combined approach of automated pattern recognition and human review. Enforcement measures will include penalties such as account suspension or removal for accounts found to be manipulating markets.

Market governance changes will tighten criteria for creating markets and strengthen rules for resolving outcomes. Polymarket said it will introduce procedural safeguards aimed at reducing disputes at settlement and will expand its compliance team to review high-volume accounts more frequently.

Polymarket said the rollout will be phased: clearer fee disclosures and interface updates will come first, followed by surveillance upgrades and revised market-creation rules. The company committed to publishing an implementation schedule, holding user forums and issuing regular transparency reports that cover fee revenue, enforcement actions and dispute outcomes.

Some traders who criticized the fee increases welcomed the announced changes and urged the platform to deliver technical fixes and policy updates. Other users requested timelines and asked whether the firm would offer compensation or fee credits to those disproportionately affected by the earlier adjustments.

Prediction markets like Polymarket allow users to trade on event outcomes and are used as tools for aggregating information about elections, economic data and other events. Such platforms face regulatory scrutiny and operational challenges, including preventing abuse, ensuring fair play and handling settlement disputes.

Polymarket said future public updates will specify release dates for new features, the criteria for enforcement actions and the frequency of transparency metrics as it implements the redesign.
