[Polymarket Quietly Introduces Taker Fees in 15-Minute Cryptocurrency Markets] According to Cointelegraph, prediction market platform Polymarket has updated its documentation, revealing that taker fees are now being charged in its 15-minute cryptocurrency markets, marking a shift from its long-standing zero-fee trading model. Based on the newly updated sections on 'Trading Fees' and 'Market Maker Rebates' in the platform's documentation, the prediction market platform has implemented taker fees in the 15-minute cryptocurrency markets to fund liquidity incentives provided to market makers. The fees collected from takers are redistributed daily to liquidity providers in the form of the USDC stablecoin, rather than being retained by the protocol. This change applies only to these short-term cryptocurrency markets, while the vast majority of Polymarket's markets remain fee-free. This update was not formally announced, but by reviewing archived versions of the documentation, it was discovered that the statements regarding the fees are newly added.
