Taker vs Maker Fees
Takers are users who fill existing orders (market orders). They pay the full fee shown in the calculator above. Makers place limit orders that add liquidity to the order book and pay zero fees. Additionally, a portion of collected taker fees (20-50% depending on the category) is redistributed daily to market makers via the Maker Rebates Program, incentivizing deeper liquidity and tighter spreads.
Why Are Polymarket Fees So Low?
Traditional sportsbooks embed 4-6% margins into their odds (called "vig" or "juice"), and that rises to 15-20% on futures and parlays. Polymarket charges explicit fees of 0.75-1.80% because it operates as a peer-to-peer exchange — users trade against each other, not against the house. The platform earns revenue from volume, not from users losing.
