Polymarket Expands Fee Structure to NCAA and Serie A Markets

Polymarket has announced an expansion of its fee structure to include NCAA basketball and Serie A markets. According to ChainCatcher, Rodrigo, an official from Polymarket, shared on Discord that the new fee mechanism will mirror the structure used in the '15-minute cryptocurrency fluctuation market.' In this system, the party placing an order pays the fee, while the party making the order receives a rebate. However, the coefficients differ, with a fee rate of 0.0175, an index of 1, and a maker rebate of 25%, resulting in overall lower fees. The new fee structure will apply to all newly created NCAA and Serie A events from 12:00 AM UTC on February 18, 2026. Existing events will remain unaffected. The first rebate distribution is scheduled for 12:00 AM UTC on February 19, 2026.
