Vice President JD Vance holds the lead in early 2028 Republican presidential primary polling and prediction markets, reflecting his role as the sitting vice president and proximity to President Trump. Recent activity centers on Vance’s extensive midterm campaigning through early November 2026, which traders view as an opportunity to build broader party support ahead of potential formal positioning. Results from those elections could influence momentum into December, while figures such as Secretary of State Marco Rubio, Senator Ted Cruz, and others explore or signal interest in the nomination. Vance has publicly noted family considerations that might affect a run, and market pricing incorporates uncertainty around endorsements, primary dynamics, and any late-year developments in candidate field formation.
Rules
This market will resolve to "Yes" if JD Vance's hourly odds value in the "2028 Republican Nomination" listing on PredictionMarketOdds.com is equal to or below 30% for 4 consecutive hourly odds values, all published for a datapoint between market creation and January 1, 2027, 12:00 AM ET. Otherwise, this market will resolve to "No". 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). An hour in which JD Vance's hourly odds value is above 30% ends any run of consecutive hourly odds values. Hours for which PredictionMarketOdds.com publishes no hourly odds value for JD Vance (shown as "NO_PRINT") will be disregarded and will neither count toward nor end a run of consecutive hourly odds values. If PredictionMarketOdds.com permanently ceases publishing hourly odds values for JD Vance in the "2028 Republican Nomination" listing before January 1, 2027, 12:00 AM ET, including by removing JD Vance from the listing, this market will resolve based on the hourly odds values published up to that point. If no hourly odds values have been published for JD Vance between market creation and January 1, 2027, 12:00 AM ET, this market will resolve to "No". If the underlying market is officially decided before the listed end date, this market will resolve to "Yes" if JD Vance is not the outcome of the underlying market and otherwise to "No". 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 JD Vance in the "2028 Republican Nomination" listing at https://predictionmarketodds.com/gop-nomination-2028.html and on JD Vance's detail page, reached by clicking the option's name in the listing. Prices shown on any individual prediction market will not be considered.
