Description

A candidate will secure the Republican Party nomination to run for the Illinois U.S. Senate seat in 2026, selected through the party's nomination process.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

Both Kalshi and Polymarket resolve based on the official Republican Party announcement of the 2026 Illinois Senate primary winner, with each platform recognizing the same set of eligible candidates and resolving YES for exactly one nominee.Primary resolution logic: Official Illinois Republican Party announcement of the primary results and nominee selection

Core resolution logic:

  • Market resolves YES if and only if the named individual wins the Republican primary nomination for the 2026 Illinois Senate seat.
  • Market resolves NO if the individual does not win the primary or if no primary takes place.
  • Exactly ONE market in the group will resolve YES (one nominee per primary).
  • Resolution is based on the first official announcement from the Illinois Republican Party or overwhelming consensus of credible reporting.
Timing: Resolution occurs upon official Illinois Republican Party announcement of the primary results and nominee selection.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.
