Polymarket to Revise Fee Structure in 2026

Polymarket has announced plans to adjust its fee structure starting March 30, 2026. According to Odaily, the platform will expand its taker fee coverage to include new market categories such as Finance, Politics, Economics, Culture, and Weather, in addition to the existing Crypto and Sports categories. The new fee rates will be calculated using a dynamic formula, with peak rates occurring near a 50% probability. The highest effective rate for Crypto is approximately 1.80%, while Finance, Politics, and Tech categories will have rates around 1.00%. Currently, only Crypto and Sports markets incur fees, while geopolitical and global event markets remain fee-free. The platform stated that the fees will be used to incentivize market makers through a Maker Rebate, enhancing liquidity. Fees will be denominated in USDC, with buy orders charged in shares and sell orders in USDC.
