Resolution rules
Each outcome is a separate contract with its own rules. The rules for J.D. Vance:
If Donald Trump publicly endorses J.D. Vance in the 2028 presidential election before Mar 1, 2028, then the market resolves to Yes. An "endorsement" requires: A clear, affirmative statement of support for candidate's election The statement must be public (not private communications) The endorsement must specifically reference the 2028 presidential election or be clearly in context of the 2028 presidential election The endorsement must come directly from Donald Trump or through official channels The following scenarios would resolve to YES: Donald Trump states "I endorse candidate for [office]" Donald Trump states "I support candidate" with clear reference to the 2028 presidential election Donald Trump states "I'm voting for candidate" publicly Donald Trump states "candidate has my full support" for the 2028 presidential election Donald Trump appears at campaign events specifically to endorse Donald Trump releases official endorsement through their organization Donald Trump allows their name/image to be used in candidate's campaign materials Statements of obvious sarcasm (or which are immediately followed by clarifications that Donald Trump is joking) are NOT encompassed by the Payout Criterion. The Contract shall resolve immediately upon confirmation of the first qualifying endorsement in the specified race. If multiple candidates are listed for a listed race and exactly one is endorsed, that candidate's strike resolves "Yes" at $1.00 and all other named-candidate strike…
