According to Foresight News , prediction market platform Polymarket recently updated its official documentation, revealing that it has introduced taker-only fees in its 15-minute cryptocurrency price fluctuation markets. This marks a change from its long-standing "zero-fee" trading model. According to the update, these fees will be used to fund liquidity incentives for market makers, and all fees paid by takers will be returned daily to liquidity providers in USDC, rather than being retained by the platform. This adjustment only applies to the 15-minute crypto market; most other markets remain at zero fees.
Transaction fees vary with market probability, peaking when the price is close to 50% and approaching zero as the probability nears 0% or 100%. Using the official example, trading 100 contracts at $0.50 would incur approximately $1.56 in fees, representing about 3% of the transaction volume at the peak of the fee curve. While no official announcement was made regarding this adjustment, document history indicates that the relevant clauses are new additions.
