The prediction market platform Polymarket is preparing to implement comprehensive trading fees throughout nearly all its market segments, effective March 30. This significant update arrives together with a freshly launched referral incentive system and reinforced market integrity protocols.
Currently, the platform only applies trading fees to cryptocurrency and sports-related prediction contracts. The revised framework will broaden this scope to encompass politics, finance, economics, cultural events, weather predictions, technology, and additional market categories.
Polymarket employs a dynamic fee calculation method based on probability rather than implementing fixed commission rates. The fee structure peaks when an event’s outcome probability hovers around 50% and diminishes progressively as certainty increases in either direction.
Category-Specific Fee Breakdown
Cryptocurrency markets will experience the steepest effective fees following this transition. The maximum rate at the 50% probability threshold will climb to 1.8%, representing an increase from the current 1.56%.
Sports-related markets will maintain their position as the most economical trading category. Peak effective fees in this segment will rise to 0.75% at 50% probability, compared to the existing 0.44%.
The majority of remaining categories will feature peak effective rates ranging from 1% to 1.56%. To illustrate, a $50 wager on a sports event positioned at 50% probability would see its fee increase from $0.22 to $0.38.
Maker orders, which contribute liquidity to the platform’s order book, continue qualifying for rebate programs. These rebates derive from taker fee revenue and are distributed daily using USDC.
Rebate calculations depend on the proportion of liquidity a user contributes that ultimately gets matched and executed. According to Polymarket, the maker rebate program is being enhanced as part of this comprehensive update.
New Referral Initiative for Active Traders
Coinciding with the fee structure modifications, Polymarket unveiled its referral program. Access requires users to have completed at least $10,000 in cumulative trading volume on the platform.
Qualified traders receive the ability to create personalized referral links for distribution without numerical restrictions. When new users register through these links and commence trading activity, the referring party receives a portion of the generated fees.
During this introductory phase, referrers collect 30% of fees produced by their direct referrals. Additionally, they receive 10% of fees generated by second-tier referrals—individuals recruited by their direct referrals.
Referral compensation remains active for 180 days following a referred user’s registration. The platform has indicated this timeframe may be modified without advance notification.
This program expands upon an earlier limited-access version. It now reaches a broader user base as part of the platform’s restructured incentive framework.
Strengthened Market Integrity Standards
Polymarket has simultaneously rolled out updated market integrity regulations alongside these operational changes. The enhanced guidelines govern both its international cryptocurrency platform and its CFTC-regulated United States exchange.
The regulations identify three distinct categories of forbidden trading conduct. These encompass trading based on misappropriated confidential data, trading on unlawfully obtained information, and trading by parties possessing the ability to influence an event’s outcome.
Users now have access to dedicated Market Integrity pages on the platform where they can submit reports of questionable activity. These pages provide comprehensive information regarding the revised regulatory framework.
Both the referral program’s 180-day compensation period and the $10,000 volume threshold are currently in effect, though Polymarket maintains discretion to modify these parameters in the future.
