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 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 Marco Rubio and JD Vance in the "2028 Republican Nomination" listing at https://predictionmarketodds.com/gop-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.**Vance remains the clear frontrunner for the 2028 Republican presidential nomination, with Rubio positioned as a distant second and explicitly stating he has no plans to run.** As sitting vice president, Vance benefits from the institutional advantages of the office, strong grassroots alignment with the MAGA base, and repeated public signals of support from President Trump. Recent polling shows Vance leading Rubio nationally and in early states, though the margin has narrowed in some surveys since earlier in the year. Rubio, serving as secretary of state and acting national security adviser, has focused on his administration roles and deferred to Vance in public comments. At the September 2026 Republican midterm convention in Dallas, Vance received prominent speaking time and enthusiastic backing from attendees, reinforcing his status as the presumptive heir. No major developments in the past month—such as shifts in Trump’s positioning, new polling surges for Rubio, or changes in Rubio’s intentions—indicate an imminent reversal of their relative standing. With only weeks until the October 31 cutoff, traders view a Rubio-led flip as improbable given the short timeline and Vance’s entrenched advantages in party support and visibility.
