<p dir="auto">两个平台当月名义交易量已达 299 亿美元历史新高，同比增幅约 588%，但繁荣的表面之下是持续深化的信息不对称。专业交易公司凭借大量数据流和算法模型系统性地在散户对手方获利，WSJ 将其比喻为&quot;高手在吃散户的午餐&quot;。内幕交易丑闻同步发酵——一名美军特种兵因利用参与委内瑞拉行动的机密情报在 Polymarket 押注马杜罗被捕、从 3.3 万美元本金套现约 40 万美元；伊朗遭袭前数小时亦出现大量匿名大额下注的异常记录；Kalshi 已对三名在平台押注自身竞选的联邦候选人实施处罚。目前内华达、亚利桑那等多个州已对 Kalshi 展开法律限制行动，两家平台均已宣布新规禁止政界人士和运动员押注本人相关合约。</p>
