Polymarket Introduces Taker Fee on 15-Minute Crypto Markets
BlockBeats News, January 6th, Predictive market platform Polymarket recently updated its official documentation, revealing that it has introduced a new taker-only fee in its 15-minute cryptocurrency price market, marking an adjustment to its long-standing "zero-fee" trading model.
According to the update, the fee is designed to fund market maker liquidity incentives, with all fees paid by takers being daily returned to liquidity providers in the form of USDC, rather than being retained by the platform. This adjustment only applies to the 15-minute crypto market, with the majority of other markets still maintaining zero fees.
The fee level varies with market probability, with the highest fees occurring when the price is close to 50%, approaching zero as it nears 0% or 100% probability. Based on an official example calculation, if 100 contracts are traded at a price of $0.50, the fee is approximately $1.56, representing about 3% of the transaction amount at the fee rate curve peak.
This adjustment was not accompanied by a formal announcement, but the document revision history indicates that the relevant terms are new additions. The community generally believes that this change is not a platform-wide fee introduction but rather a market structure optimization targeting high-frequency bots and wash trading, aimed at improving liquidity quality and tightening spreads. Polymarket stated that long-duration event markets, political markets, and non-crypto prediction markets are not affected, with limited overall impact on regular users.
