Democratic nomination odds leader on October 31?

根據「Democratic nomination odds leader on October 31?」的最新預測市場資料，交易者已形成強烈共識。

目前，Gavin Newsom 以壓倒性的 44% 獲勝機率主導市場；Jon Ossoff 以 42% 位居第二，Alexandria Ocasio-Cortez 以 7% 排名第三。該市場的下注量已達 $155.2K，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

• Gavin Newsom (44%)：Gavin Newsom 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 44¢，顯示出市場的高度確信。僅該合約就已產生 $45.8K 的成交量。

🥈 第二梯隊：主要挑戰者

• Jon Ossoff (42%)：作為最可行的替代選項，Jon Ossoff 保持著 42% 的成真機率，其「Buy Yes」份額目前成交價為 42¢。
• Alexandria Ocasio-Cortez (7%)：以 7% 的機率位列第三，市場對 Alexandria Ocasio-Cortez 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 7%）

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 Kamala Harris (0.2%)，以及 Josh Shapiro (0.2%)。
• 投機成交：儘管統計機率偏低，像 Kamala Harris 這類長尾合約仍吸引著可觀的關注。

This market will resolve according to the option with the highest hourly odds value in the "2028 Democratic Nomination" listing on PredictionMarketOdds.com for the "Time Window (ET)" ending at 12:00 PM ET on October 31, 2026. If that option is not a listed outcome of this market, this market will resolve to "Other".

An hourly odds value is the value in the "Odds of Happening" column that PredictionMarketOdds.com publishes for an option for a one-hour "Time Window (ET)", as shown on the listing page and in the "Odds History" graph on that option's detail page. Hourly odds values are compared at the precision published by PredictionMarketOdds.com (one tenth of a percent).

If PredictionMarketOdds.com publishes "NO_PRINT" for an option for the specified window, that option's most recent published hourly odds value before the specified window will be used. If PredictionMarketOdds.com has not published anything for the specified window for an option (neither an hourly odds value nor "NO_PRINT"), this market will remain open until a value or "NO_PRINT" for that window is published, and may remain open until November 7, 2026, 11:59 PM ET for that purpose. If nothing has been published for the specified window by that time, that option's most recent published hourly odds value before the specified window will be used. An option with no hourly odds value published in that period will not be considered.

If two or more options are tied for the highest value, the tie will be broken in favor of the tied option with the higher value in the most recent earlier window in which their values differed. If the tie persists, this market will resolve in favor of the tied option whose listed name comes first alphabetically.

If the underlying market is officially decided before the listed end date, this market will resolve in favor of the outcome of the underlying market if it is a listed outcome, and otherwise to "Other".

If a published hourly odds value is clearly erroneous as a result of a technical or operational error, this market may remain open for up to an additional 48 hours after that value is first published to allow for a correction. A corrected value will be used in place of the original. If no correction is published within that period, the original value will stand, and revisions published after that period will not be considered.

The resolution source for this market is PredictionMarketOdds.com, specifically the hourly odds values for the options in the "2028 Democratic Nomination" listing at https://predictionmarketodds.com/dem-nomination-2028.html and on each option's detail page, reached by clicking the option's name in the listing. Prices shown on any individual prediction market will not be considered.

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：Gavin Newsom 當前交易價為 44%，但我們的 AI 測算其公允價值僅為 22.1%，形成 -21.9% 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 Alexandria Ocasio-Cortez 識別為盤面上最具價值的機會。市場僅給予其 7% 的交易機率，而我們 AI 的公允價值評估為 21.6%——形成可觀的 +14.6% EV 差。
• 被忽視的黑馬：其他值得注意的偏離包括 Kamala Harris（EV 差：+14.3%）以及 Josh Shapiro（EV 差：+12.7%）。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。
