合约交易Polymarket在15分钟加密市场引入Taker手续费
BlockBeats 消息，1 月 6 日，预测市场平台 Polymarket 近期更新官方文档，显示其已在 15 分钟周期的加密货币涨跌市场中引入仅针对 taker 的手续费，这标志着其长期「零手续费」交易模式出现调整。
根据更新内容，相关手续费将用于资助做市商流动性激励，所有由 taker 支付的费用将以 USDC 形式每日返还给流动性提供者，而非由平台留存。该调整仅适用于 15 分钟加密市场，其余大多数市场仍维持零手续费。
手续费水平随市场概率变化，当价格接近 50% 时费用最高，向 0% 或 100% 概率靠近时则趋近于零。以官方示例计算，若以 0.50 美元价格成交 100 份合约，手续费约为 1.56 美元，在费率曲线峰值时约占交易额的 3%。
此次调整未发布正式公告，但文档历史记录显示相关条款为新增内容。社区普遍认为，这一变化并非平台全面收费，而是针对高频机器人和刷量交易的市场结构优化，旨在提升流动性质量、缩小点差。Polymarket 表示，长期事件市场、政治市场及非加密预测市场不受影响，普通用户整体影响有限。
