Polymarket Expands Fee Mechanism to Sports Markets Including NCAA Basketball and Serie A

Polymarket Expands Fee Structure to Sports Markets

On February 13, 2026, Rodrigo, a representative from Polymarket, announced on Discord that the platform would extend its fee mechanism to markets related to NCAA basketball and Serie A. The structure resembles that of the cryptocurrency markets, but with adjusted rates and incentives designed to reduce overall trading costs.

Detailed Fee Model

The new fee model follows a taker-pays, maker-receives-incentive structure. Takers will pay a rate of 0.0175 with an exponent of 1, while makers will receive a 25% rebate. This approach aims to encourage market participation and liquidity provision.

Implementation Timeline and Scope

The updated fee system will apply to all new NCAA and Serie A-related markets created after 00:00 UTC on February 18, 2026. Previously created markets will remain unaffected, and the first rebates will be distributed at 00:00 UTC on February 19.

Enhancing Market Liquidity

By introducing this optimized fee structure, Polymarket aims to attract more traders and liquidity providers, boost market engagement, and provide a more efficient and fair trading environment for sports-related prediction markets.
