Polymarket is extending its fees to the sports market, starting February 18th, and will charge fees for NCAA and Italian Serie A events.

According to Odaily Planet Daily, Rodrigo, an official from Polymarket, announced on Discord that the fee structure will be extended to the NCAA (College Basketball) and Serie A (Italian Football League) markets. The fee structure is the same as the "15-minute cryptocurrency price fluctuation market," where the taker pays the fee and the maker receives a rebate. However, the coefficients are different—the fee rate is 0.0175, the index is 1, and the maker receives a 25% rebate, resulting in lower overall costs. Starting at midnight UTC on Wednesday, February 18, 2026, all newly created NCAA and Serie A events will be subject to the new fee structure. Existing events will not be affected. The first rebate will be issued at midnight UTC on February 19.
