Monitoring by the Svmuu Seer Channel shows that according to official Polymarket documentation, the platform will adjust its fee mechanism starting March 30, 2026. In addition to the existing Crypto and Sports categories, several new market categories including Finance, Politics, Economics, Culture, and Weather will be brought under the taker fee scope. The new fee rate is calculated using a dynamic formula, with peaks concentrated around the 50% probability mark. The highest effective fee rate for the Crypto category is approximately 1.80%, while categories like Finance, Politics, and Tech are around 1.00%.
Currently, only Crypto and Sports markets charge fees, while markets related to geopolitics and global events remain fee-free. The platform stated that the collected fees will be used for Maker Rebates to incentivize market makers to provide liquidity. Fees are denominated in USDC, with buy orders charged in the form of shares and sell orders charged in USDC.
The Svmuu Seer Channel continues to monitor prediction markets, seeing change before it's priced in.
