Description

This group forecasts who will be the Republican Vice-Presidential nominee in the 2028 US Presidential election. The market resolves based on the first individual formally nominated by the Republican Party and who accepts the nomination.

PredictionHero - Resolution Divergence Alerts (RDA)

Divergence Detected

Issue: Kalshi lists numerous potential candidates, resolving YES if any are nominated and accept, while Polymarket has individual markets for each candidate and relies on official GOP sources for resolution.Hero tip: Focus on Polymarket markets for individual candidates as they provide a clearer resolution path tied to official nomination processes. Be cautious of Kalshi's broad scope, which could lead to unexpected resolutions.

Critical divergence points:

  • Polymarket: Each candidate has a dedicated market resolving YES if they are formally nominated *and* accept the nomination, using official GOP sources (https://www.gop.com) as the primary source.
  • Kalshi: Resolves YES if *any* of the listed individuals (a very extensive list) accept the nomination for Vice President. No specific source is prioritized beyond the acceptance of the nomination.
Our PredictionHero Resolution Divergence Alerts (RDA) are there to help users identify potential differences across platforms. They do not replace or supersede the official rules and description of any prediction market. Users are solely responsible for reviewing and understanding the applicable rules and resolution criteria before placing any trade or bet. If you notice a potential inconsistency, discrepancy, or error in an alert, please report it to our team so we can review and improve the accuracy of our data.

Polymarket

This market will resolve according to the first individual to be formally nominated by the Republican Party for Vice President of the United States in the 2028 presidential election cycle who accepts the nomination. The resolution source for this market will be a consensus of official GOP sources, including https://www.gop.com. Any replacement of the nominee before election day will not change the resolution of the market.
