Resolution rules
This market will resolve to "Yes" if Marco Rubio's hourly odds value is higher than JD Vance's hourly odds value in the "2028 Republican Nomination" listing on PredictionMarketOdds.com for 4 consecutive hourly odds values, all published for a datapoint between market creation and November 1, 2026, 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. Hourly odds values are compared at the precision published by PredictionMarketOdds.com (one tenth of a percent). An hour in which the two values are equal does not count as Marco Rubio being higher and ends any run of consecutive hourly odds values. Hours for which PredictionMarketOdds.com publishes no hourly odds value for either option (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 Marco Rubio or JD Vance in the "2028 Republican Nomination" listing before November 1, 2026, 12:00 AM ET, including by removing either option 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 both Marco Rubio and JD Vance between market creation and November 1, 2026, 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 Marco Rubio is 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
