Starting Wednesday, February 18th, 2026 at midnight (UTC), taker fees and maker rebates will apply to all new NCAAB and Serie A markets created after that time. Existing markets are not affected. The first payout will be on February 19th at midnight (UTC).
Why Expand Maker Rebates?
Sports markets benefit from the same dynamics as our 15-minute crypto and 5-minute crypto markets. When liquidity is deeper:- Spreads tend to be tighter
- Price impact is lower
- Fills are more reliable
- Markets are more resilient during volatility
Program Funding
Maker Rebates are funded by taker fees collected in eligible markets. A percentage of these fees are redistributed to makers who keep the markets liquid. The rebate percentage differs by market type.| Market Type | Period | Maker Rebate | Distribution Method |
|---|---|---|---|
| 15-Min Crypto | Jan 19, 2026+ | 20% | Fee-curve weighted |
| 5-Min Crypto | Feb 12, 2026+ | 20% | Fee-curve weighted |
| Sports (NCAAB, Serie A) | Feb 18, 2026+ | 25% | Fee-curve weighted |
Polymarket collects taker fees in eligible markets (15-minute crypto, 5-minute crypto, NCAAB, and Serie A). The rebate percentage is at the sole discretion of Polymarket and may change over time.
Taker Fee Structure
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. Fees are highest at 50% probability and lowest at the extremes (near 0% or 100%).
