Description

This market will resolve to “Yes” if the named individual wins and accepts the 2028 nomination of the Democratic Party for U.S. president. Otherwise, this market will resolve to “No”. The resolution source for this market will be a consensus of official Democratic Party sources. Any replacement of the democratic nominee before election day will not change the resolution of the market.

PredictionHero - Resolution Divergence Alerts (RDA)

Unified Resolution Criteria (Consistent across platforms)

All three platforms (Kalshi, Polymarket, Limitless) employ identical binary resolution logic tied to official Democratic Party sources, with consistent treatment of nominee replacement scenarios.

Primary resolution logic:

Consensus of official Democratic Party sources, including DNC announcements and Democratic National Convention proceedings

Core resolution logic:

  • Market resolves YES if and only if the named individual wins and accepts the 2028 Democratic Party presidential nomination
  • Market resolves NO if the named individual does not win the nomination or does not accept it
  • Resolution is based on official Democratic Party sources and convention records
  • Any replacement of the Democratic nominee before election day does not change the resolution of the market
  • Polymarket and Limitless explicitly note that replacement scenarios do not alter the original resolution

Edge cases & Clarifications:

  • Nominee Replacement Before Election Day: If the initially nominated candidate is replaced before the general election (e.g., due to withdrawal, death, or party action), the market still resolves based on who originally won and accepted the nomination at the convention. The replacement does not trigger a re-resolution.
  • Acceptance Requirement: The nominee must both win the nomination AND accept it. Winning alone is insufficient; explicit acceptance is required for YES resolution.
  • Unknown or Unconfirmed Nominee: Limitless includes an Other category that resolves YES if the nominee is not listed or not known by November 7, 2028, 11:59 PM ET. Kalshi and Polymarket do not explicitly address this scenario but would resolve NO for any unlisted candidate.
  • Multiple Candidates Listed: Kalshi lists 45 specific candidates; Polymarket lists approximately 130 questions (many with coded identifiers like Person S, Person AB); Limitless lists 5 specific candidates plus Other. Only one can win; all others resolve NO.
  • Coded Identifiers on Polymarket: Polymarket uses coded identifiers (Person S, Person AB, etc.) for some candidates. These are treated identically to named candidates; resolution logic is unchanged.

Timing:

Resolution occurs upon official acceptance of the 2028 Democratic Party presidential nomination, typically at or immediately following the Democratic National Convention. For Limitless, if the nominee is not known by November 7, 2028, 11:59 PM ET, the Other market resolves YES and all named-candidate markets resolve NO.
