Market Rulebook: Who will Bernie Sanders endorse before the midterms?
Official settlement criteria, resolution sources, and edge cases across Kalshi and Polymarket.
Kalshi
Primary Rule
If Bernie Sanders publicly endorses Antonio Delgado in the 2026 New York gubernatorial election before Nov 3, 2026, then the market resolves to Yes.
Edge Cases
An endorsement requires a clear, affirmative statement of support for the nominee's election. The statement must be public (not private communications) and specifically reference the race or be clearly in context of the race. The endorsement must come directly from the person or through their official channels. Positive comments without explicit support, policy endorsements without nominee endorsement, or conditional endorsements do not qualify. Social media endorsements count only from verified accounts, and likes or retweets alone do not constitute endorsement. Quote tweets with additional supportive commentary do count. Sarcastic statements or those immediately clarified as jokes do not qualify.
This market will resolve according to the candidate Bernie Sanders announces that he will vote for or endorses for the listed election.
If Bernie Sanders does not announce an endorsement by the day before the scheduled election at 11:59 PM ET, this market will resolve to "No".
The resolution source for this market will be official information from Bernie Sanders or one of his representatives, or a consensus of credible reporting of Bernie Sanders' endorsement.
