To better assess where each potential outcome stands, the market can be segmented into three distinct trading tiers based on implied probability and contract pricing:

🥇 Tier 1: The Dominant Leader

• No (79%): Currently commanding the highest probability, No is heavily favored by the order book. Traders looking to back this outcome face a “Buy Yes” contract price of 79¢, signaling a high degree of market conviction.

🥈 Tier 2: The Primary Challengers

• Yes (21%): Positioned as the most viable alternative, Yes maintains a 21% chance of resolving true. Its “Buy Yes” shares currently trade at 21¢.

This market will resolve to "Yes" if Donald Trump publicly endorses, or announces that he will vote for, JD Vance for the 2028 United States presidential election or the Republican primary for that election, by December 31, 2026, 11:59 PM ET. Otherwise this market will resolve to "No".

If Donald Trump announces that he will vote for another candidate or endorses another candidate for the 2028 United States presidential election or the Republican primary for that election, this market will immediately resolve to "No".

The resolution source for this market will be official information from Donald Trump or one of his representatives, or a consensus of credible reporting of Trump's endorsement.

While human consensus and speculative volume shape the broader prediction market, our quantitative algorithms offer a data-driven counter-perspective. By analyzing fundamental signals, underlying trends and historical distributions, our AI Valuation model calculates an independent “Fair Value” probability for each outcome.

Comparing this Fair Value against the current Trade Value uncovers major disparities — known as the Expected Value (EV) Gap. Contracts with a positive EV Gap represent statistically underpriced outcomes, whereas a negative EV Gap flags a potential market overreaction.

Top AI Alpha & Mispriced Arbitrage Opportunities

Based on the latest data model run, several key contracts stand out with significant deviations:

• The Most Overvalued Outcome Yes currently trades at 21%, but our AI places its Fair Value at just 17.4%. This creates a large negative EV Gap of -3.6%, suggesting the crowd may be overhyping this outcome and driving the premium too high.
• The Best Value Play (Highest EV) Our model identifies No as the premium value opportunity on the board. While the market only assigns it a 79% trading probability, our AI’s Fair Value assessment sits at 82.6% — yielding an impressive +3.6% EV Gap.
