Lowest Mississippi level at St. Louis by November 30?

根据「Lowest Mississippi level at St. Louis by November 30?」的最新预测市场数据，交易者已形成强烈共识。

目前，1.00 to 2.99 ft 以压倒性的 69.5% 获胜概率主导市场；-1.00 to 0.99 ft 以 18.5% 位居第二，Below -3.00 ft 以 3.9% 排名第三。该市场的下注量已达 $97.9K，反映出市场的高度关注。

为了更好地评估各潜在结果的位置，可依据隐含概率与合约定价将市场划分为三个明显的交易梯队：

🥇 第一梯队：绝对领跑者

• 1.00 to 2.99 ft (69.5%)：1.00 to 2.99 ft 目前拥有最高概率，深受订单簿青睐。看好该结果的交易者面对的「Buy Yes」合约价为 70¢，显示出市场的高度确信。仅该合约就已产生 $22.7K 的成交量。

🥈 第二梯队：主要挑战者

• -1.00 to 0.99 ft (18.5%)：作为最可行的替代选项，-1.00 to 0.99 ft 保持着 18.5% 的成真概率，其「Buy Yes」份额目前成交价为 19¢。
• Below -3.00 ft (3.9%)：以 3.9% 的概率位列第三，市场对 Below -3.00 ft 持谨慎怀疑态度，除非势头转变，否则视其为外围黑马。

🥉 第三梯队：长尾选项（合计约 8.2%）

在前三名之外，还有大量宏观变量与冷门结果被持续追踪。尽管单个概率偏低，但它们是投机交易者的重要对冲：

• 替代选项：包括 -3.00 to -1.01 ft (3.3%)，以及 3.00 ft or more (1.1%)。
• 投机成交：尽管统计概率偏低，像 -3.00 to -1.01 ft 这类长尾合约仍吸引着可观的关注。

This market will resolve according to the lowest gage height (river level), in feet, recorded at the Mississippi River at St. Louis, MO streamgage (USGS site 07010000) between market creation and November 30, 2026, as published by the United States Geological Survey (USGS) for parameter code 00065 under statistic code 30800. Exactly one outcome in this market will resolve to "Yes".

The lowest daily reading in the window decides this market; the level does not need to be sustained. If USGS does not publish a reading for one or more days, this market will resolve according to the lowest reading among the days that are published.

Values will be used exactly as published by USGS, without rounding. USGS reports gage height at this gage to 2 decimal places. Each range includes both of its stated bounds and consecutive ranges are contiguous, so every reading falls in exactly one range: a lowest reading of exactly -1.00 ft resolves the range beginning at -1.00 ft to "Yes" and every other range to "No".

This market will resolve on the values published at the time of resolution, whether flagged provisional ("P") or approved ("A"); revisions published afterward will not be considered, except where the correction provision below applies.

If any data remains unpublished or unfinalized, this market will remain open for up to 2 calendar days (ET) after November 30, 2026; it will then resolve based on the finalized data published up to that point.

In case of obvious data integrity issues (i.e., erroneous data), the market may remain open until the end of the third calendar day (ET) after such data is first released to allow for corrections; this applies only to clerical or similar errors, not to USGS differing from other sources.

If the source is unavailable, this market may be extended to December 15, 2026, 11:59 PM ET. If no data for the window is available by then, this market will resolve to "Below -3.00 ft".

The primary resolution source for this market will be the USGS Daily Values service for site 07010000; however, a consensus of credible reporting may also be used. The service is available here: https://waterservices.usgs.gov/nwis/dv/?sites=07010000&parameterCd=00065&statCd=30800&startDT=2026-09-21&endDT=2026-11-30&format=rdb

人群共识与投机成交塑造了更宏观的预测市场，而我们的量化算法提供了数据驱动的反向视角。通过分析基本面信号、底层趋势与历史分布，我们的 AI 估值模型为每个结果独立测算出一个「公允价值」概率。

将该公允价值与当前交易价值对比，可揭示出重大背离——即期望值（EV）差。正 EV 差代表统计上被低估的结果，而负 EV 差则提示市场可能存在反应过度。

顶级 AI Alpha 与错误定价套利机会

根据最新一轮数据模型测算，以下几个关键合约存在显著偏离：

• 最被高估的结果：1.00 to 2.99 ft 当前交易价为 69.5%，但我们的 AI 测算其公允价值仅为 40%，形成 -29.5% 的较大负 EV 差，表明人群可能过度炒作该结果、把溢价推得过高。
• 最佳价值标的（最高 EV）：我们的模型将 3.00 ft or more 识别为盘面上最具价值的机会。市场仅给予其 1.1% 的交易概率，而我们 AI 的公允价值评估为 13.6%——形成可观的 +12.5% EV 差。
• 被忽视的黑马：其他值得注意的偏离包括 -1.00 to 0.99 ft（EV 差：+9.9%）以及 -3.00 to -1.01 ft（EV 差：+8%）。尽管我们的预测模型给予更强的统计支撑，这些长尾机会仍被实时订单簿大幅低估。
