# Polymarket expands its fee structure: Starting March 30, it will begin charging transaction fees to more markets.

According to Odaily Seer's monitoring, Polymarket's official documentation indicates that the platform will adjust its fee structure 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 included in the taker fee scope. The new rates are calculated using a dynamic formula, with peak rates concentrated around a 50% probability. The highest effective rate for Crypto is approximately 1.80%, while Finance, Politics, and Tech are around 1.00%. Currently, only the Crypto and Sports markets charge fees; geopolitical and global event markets remain fee-free. The platform states that fees will be used for Maker Rebate to incentivize market makers to provide liquidity. Fees are denominated in USDC, with buy orders charged in shares and sell orders charged in USDC. Odaily Seer continuously monitors the prediction market, anticipating changes before pricing.
