On April 1, the Polymarket team announced on Discord that in response to community concerns regarding high fees in certain categories, their initial intention was to fix the fee curve. However, they mistakenly used USD taker transaction volume, and have now switched to calculating based on the number of shares, which is the industry standard and will eliminate fee imbalances. The team noted that in some markets (especially weather and economic markets), the fee curve was severely distorted due to this change and the additional indices added to these two categories. Fees were abnormally high at lower prices (such as 0.1¢), which led to complaints about 'super high fees' on social media. The fee schedule has now been revised, the indices removed, and this situation no longer exists in any market. 'The fees in these markets are still the lowest and most cost-effective on the internet.' The team also suggested that if users are concerned about fees, they can place limit orders for free trading, and with the new update, they can receive a 20-25% maker rebate.
