被誉为“真理机器”的预测市场正迎来爆发式增长，但也因合约结算机制的缺陷陷入严重瓶颈。作为行业领头羊，美国合规交易平台 Kalshi 的月交易量在6月份跃升至330亿美元，同比激增40倍，公司估值达到400亿美元；而其竞争对手 Polymarket 的估值也达到了150亿美元。预测市场通过价格发现机制为公众和企业提供了评估未来风险的工具，甚至支持个人开展针对政策变动的对冲交易，但结算流程的模糊性极大地制约了其向主流金融领域的拓展。

两种不同的结算模式暴露出了各自的系统性弊端。总部设在巴拿马、基于区块链的 Polymarket 依赖其去中心化预言机 UMA 进行代币持有者投票结算，但调查表明少数核心加密钱包控制了绝大多数投票权，导致大额交易者能够操纵自身投注结果。相比之下，在联邦监管下运营的 Kalshi 依靠由前辩论冠军组成的专业团队制定规则并人工结算，虽然杜绝了内部交易，但面对每天超过10,000个涵盖政治、经济和技术等领域的复杂合约，团队产能严重不足，导致措辞模糊和裁判标准前后不一。

为了维持长期增长并吸引机构投资者的万亿美元级资金，预测市场必须建立标准化、透明化且具备法律可预测性的制度框架。合约条文必须在公开发售前经过领域专家严密审定，结算决定需要具备法理判例效力，并接受独立监管机构的严格监督。唯有完善基础设施建设并消除随意性结算，预测市场才能真正承担起全球金融体系中“真理机器”的风险定价功能。 

Prediction markets, frequently dubbed "truth machines," are experiencing exponential growth while grappling with settlement flaws. Market leader Kalshi saw its monthly trading volume scale to billion in June, representing a 40-fold year-on-year surge and driving its valuation to billion, while competitor Polymarket reached a billion valuation. These platforms leverage collective intelligence to price future probabilities, allowing users and businesses to hedge real-world exposure against policy changes and geopolitical shifts. However, contract settlement mechanics remain vulnerable to dispute.

Existing settlement architecture demonstrates distinct structural vulnerabilities across platform models. Polymarket, operating on a decentralized crypto infrastructure, utilizes a token-voting oracle (UMA) to resolve ambiguous contract language; however, investigations reveal that a small cluster of crypto wallets controls a voting majority, enabling big traders to manipulate outcomes in their favor. Conversely, US-regulated Kalshi employs an internal team of debaters to draft rules and determine resolutions without market participation, yet this small workforce cannot manage over 10,000 daily contracts, resulting in ambiguous phrasing, typos, and contradictory resolution precedents.

For prediction markets to sustain institutional adoption and integrate into global financial markets, settlement predictability must be rigorously established. Financial exchanges require upfront contract precision, domain-expert rule drafting, and binding legal precedents to resolve ambiguous real-world events. Strengthening regulatory oversight and eliminating arbitrary settlement mechanisms are essential prerequisites for prediction markets to fulfill their function as reliable risk-management tools.
