Polymarket quietly introduces Taker fees in 15 minute cryptocurrency market According to BlockBeats, on January 6th, the prediction market platform Polymarket recently updated its official document, showing that it has introduced a transaction fee only for the taker in the 15 minute cycle of cryptocurrency fluctuations, marking a correction in its long-term "zero transaction fee" trading model. According to the updated content, the relevant handling fees will be used to fund liquidity incentives for market makers, and all fees paid by the taker will be returned to the liquidity provider in USDC form on a daily basis, rather than being retained by the platform. This adjustment only applies to the 15 minute cryptocurrency market, while most other markets still maintain zero transaction fees. The level of transaction fees varies with market probability, with the highest fees occurring when the price approaches 50%, and approaching zero when the probability approaches 0% or 100%. Based on official examples, if 100 contracts are executed at a price of $0.50, the transaction fee is approximately $1.56, which accounts for about 3% of the transaction amount at the peak of the rate curve. This adjustment has not been officially announced, but the document history shows that the relevant terms are new content. The community generally believes that this change is not a comprehensive platform fee, but rather an optimization of the market structure for high-frequency robots and volume boosting trading, aimed at improving liquidity quality and reducing spreads. Polymarket stated that the long-term event market, political market, and non crypto prediction market are not affected, and the overall impact on ordinary users is limited.
