How many West Nile neuroinvasive disease cases will be reported among New York City residents in 2026?

根據「How many West Nile neuroinvasive disease cases will be reported among New York City residents in 2026?」的最新預測市場資料，交易者已形成強烈共識。

目前，20 to 34 以壓倒性的 74% 獲勝機率主導市場；35 to 49 以 25.7% 位居第二，50 or more 以 0.4% 排名第三。該市場的下注量已達 $89.6K，反映出市場的高度關注。

為了更好地評估各潛在結果的位置，可依據隱含機率與合約定價將市場劃分為三個明顯的交易梯隊：

🥇 第一梯隊：絕對領跑者

• 20 to 34 (74%)：20 to 34 目前擁有最高機率，深受訂單簿青睞。看好該結果的交易者面對的「Buy Yes」合約價為 74¢，顯示出市場的高度確信。僅該合約就已產生 $37.5K 的成交量。

🥈 第二梯隊：主要挑戰者

• 35 to 49 (25.7%)：作為最可行的替代選項，35 to 49 保持著 25.7% 的成真機率，其「Buy Yes」份額目前成交價為 26¢。
• 50 or more (0.4%)：以 0.4% 的機率位列第三，市場對 50 or more 持謹慎懷疑態度，除非勢頭轉變，否則視其為外圍黑馬。

🥉 第三梯隊：長尾選項（合計約 0%）

在前三名之外，還有大量宏觀變數與冷門結果被持續追蹤。儘管單個機率偏低，但它們是投機交易者的重要對沖：

• 替代選項：包括 Fewer than 20 (0.1%)。
• 投機成交：儘管統計機率偏低，像 Fewer than 20 這類長尾合約仍吸引著可觀的關注。

This market resolves based on the total number of West Nile neuroinvasive disease cases (encephalitis, meningitis, and acute flaccid paralysis) reported among New York City residents in 2026, as published by the New York City Department of Health and Mental Hygiene on its West Nile Virus Reports page at nyc.gov/site/doh/health/health-topics/west-nile-virus-reports.page.

Cases are counted as whole numbers, so each outcome covers a distinct range with no overlap or gap.

The 2026 count shown on the source as of January 1, 2027 is the starting figure.

If the DOHMH publishes or revises the 2026 count on or after January 1, 2027, this market will resolve based on the count shown on the source at 11:59 PM ET on the 14th day after the first such update, or on March 31, 2027, 11:59 PM ET, whichever comes first. If no such update occurs, this market will resolve on March 31, 2027, 11:59 PM ET, based on the 2026 count shown on the source at that time.

If no 2026 count has been published on the source by March 31, 2027, 11:59 PM ET, this market will resolve based on the sum of 2026 West Nile neuroinvasive disease case counts reported by CDC ArboNET for the five New York City counties (Bronx, Kings, New York, Queens, and Richmond). Revisions published after this market resolves will not be considered. If the DOHMH changes its reporting format or URL structure, the closest equivalent NYC Health Department publication of 2026 West Nile neuroinvasive case data will be used.

人群共識與投機成交塑造了更宏觀的預測市場，而我們的量化演算法提供了資料驅動的反向視角。透過分析基本面訊號、底層趨勢與歷史分布，我們的 AI 估值模型為每個結果獨立測算出一個「公允價值」機率。

將該公允價值與當前交易價值對比，可揭示出重大背離——即期望值（EV）差。正 EV 差代表統計上被低估的結果，而負 EV 差則提示市場可能存在反應過度。

頂級 AI Alpha 與錯誤定價套利機會

根據最新一輪資料模型測算，以下幾個關鍵合約存在顯著偏離：

• 最被高估的結果：20 to 34 當前交易價為 74%，但我們的 AI 測算其公允價值僅為 57.5%，形成 -16.4% 的較大負 EV 差，表明人群可能過度炒作該結果、把溢價推得過高。
• 最佳價值標的（最高 EV）：我們的模型將 Fewer than 20 識別為盤面上最具價值的機會。市場僅給予其 0.1% 的交易機率，而我們 AI 的公允價值評估為 24.4%——形成可觀的 +24.3% EV 差。
• 被忽視的黑馬：其他值得注意的偏離包括 50 or more（EV 差：+1.5%）。儘管我們的預測模型給予更強的統計支撐，這些長尾機會仍被即時訂單簿大幅低估。
