去年夏天，用户“ricosuave666”在 Polymarket 通过对以色列袭击伊朗“精确时点”的可疑高准确度押注获利超过150,000美元；2月12日，以色列宣布逮捕两名男子（其中一人近期为陆军预备役），并指控其利用机密信息进行押注。该案把一次高额收益与具体执法数字直接绑定，凸显了内幕信息与预测市场交易之间的风险连接。
这并非孤例：近年预测市场规模显著膨胀，同时可疑“提前押中”事件在多个平台反复出现，包括1月马杜罗被推翻相关盈利押注、去年玛丽亚·科里纳·马查多获诺奖前数小时赔率飙升，以及12月 Kalshi 上关于 Spotify 年度最高流媒体歌曲的争议交易。跨平台、跨主题、跨时间点的密集异常，显示信息优势交易并非偶发噪声，而是随市场扩张同步上升的结构性趋势。
监管结构存在明显不对称：美国受监管平台归 CFTC 管辖，但“商品”（含预测合约）的内幕交易规则弱于“证券”，而离岸平台约束更少；平台因此依赖 KYC、冻结账户与追踪雇主/地点来维持公信力。政策权衡在于，全面禁止会赶走高信息交易者并削弱概率定价准确性这一外部收益，但2012年《Stock Act》已对公职人员设更高标准，因而至少对政府官员实施内幕押注禁令的论据正在增强。
Last summer, user “ricosuave666” made more than $150,000 on Polymarket through suspiciously accurate bets on the precise timing of Israel’s attacks on Iran; on February 12, Israel announced the arrest of two men (one recently an army reservist) and charged them with betting via classified information. The case ties a large payout to concrete enforcement numbers and highlights the risk link between insider information and prediction-market trading.
This is not isolated: prediction markets have expanded sharply in recent years, while repeated “pre-event” wins appeared across platforms, including profitable January bets on Maduro’s toppling, a surge in María Corina Machado’s Nobel odds hours before confirmation last year, and disputed December trading on Kalshi about Spotify’s top-streamed song. The density of anomalies across platforms, topics, and time points indicates that information-advantaged trading is not random noise but a structural trend rising with market growth.
The regulatory architecture is asymmetric: U.S.-regulated venues fall under the CFTC, but insider-trading rules for “commodities” (including prediction contracts) are weaker than for “securities,” while offshore markets face fewer constraints; platforms therefore rely on KYC, account freezes, and employer/location tracing to preserve trust. The policy tradeoff is that a total ban could expel highly informed traders and reduce the positive externality of more accurate probabilities, but the 2012 Stock Act already applies stricter expectations to public officials, strengthening the case for at least banning insider betting by government employees.
