Gate News 消息，3 月 19 日，随着机构与量化基金持续进入预测市场，行业交易结构正在发生转变。数据显示，2026年3月预测市场月交易量已突破137亿美元，同比大幅增长，Polymarket等平台逐渐演变为专业资金博弈的新阵地。
分析人士指出，当前预测市场已从早期的投机行为转向量化驱动的策略竞争，对冲基金开始引入成熟的金融模型以获取稳定收益。其中六大核心方法成为主流框架。
首先，对数市场评分规则（LMSR）被用于解析定价机制，帮助交易者预判订单对市场价格的冲击。凯利准则则用于优化仓位管理，通过数学模型确定每笔交易的资金比例，避免情绪化决策。
在机会识别方面，期望值差距扫描通过构建独立概率模型，寻找市场定价与真实概率之间的偏差；KL背离用于捕捉相关市场间的不一致，从而构建对冲策略。布雷格曼投影进一步拓展至多结果事件，识别复杂定价错误。与此同时，贝叶斯更新则根据新信息动态调整概率，使策略持续贴合市场变化。
技术实现层面，量化团队通常通过API获取实时数据，并借助Python及相关数学库进行建模与回测。在正式部署前，需基于历史数据进行前瞻性测试，以降低过拟合风险。自动化执行系统通常结合定时任务与实时提醒机制，提高反应速度。
不过，该类策略对执行要求较高，包括数据质量、流动性深度及交易成本控制等因素都会直接影响收益表现。业内人士认为，预测市场正逐步向类似期权与期货市场的专业化结构演进，但普通投资者若缺乏模型能力与纪律管理，仍难以复制机构优势。
