Polymarket Adds Taker Fees to 15-Minute Crypto Markets

Prediction market platform Polymarket quietly updated its documentation to implement taker-only fees on its 15-minute crypto up/down markets, moving away from its previous zero-fee model. These collected fees are redistributed daily in USDC to liquidity providers, not retained by the protocol. The fee structure varies based on market odds, peaking near 50% odds (around 3% for a sample trade) and dropping toward zero at the extremes. Community reaction framed this as a market structure adjustment intended to increase protection from wash trading and incentivize market makers with tighter spreads, rather than a general platform tax. The change only affects these short-duration crypto markets; the vast majority of Polymarket's other markets remain fee-free.
