Gotcha risk — resolution-rule assessment

Show full assessmentShow less

The rules provide clear and objective mechanics for resolution. The outcome is determined when three explicitly named media outlets (Associated Press, Fox News, and NBC) all project the same winner, with an unambiguous fallback to official state election certification if they disagree. Candidate substitution, independent affiliations, and potential run-offs are explicitly defined, leaving minimal room for decider interpretation or unexpected outcomes.

Resolution rules

This market will resolve according to the winner of the 2026 midterm Montana U.S. Senate election, inclusive of any run-offs. A candidate shall be considered to represent a party in the event that he or she is the nominee of the party in question. Candidates other than the Democratic or Republican nominee (e.g., Greens, Libertarian, independent) may be added at a later date. Candidates who run as independents will not be encompassed by the “Democrat” or “Republican” options regardless of any affiliation they may have with the party. The candidates may be named in the contract for the convenience of traders. In the event that any named candidate is replaced as the nominee of their respective party prior to election day, the name in the contract will be updated and the market will resolve based on the replacement nominee of the party. The resolution source for this market is the Associated Press, Fox News, and NBC. This market will resolve once all three sources call the race for the same candidate. If all three sources haven’t called the race in this state for the same candidate, this market will resolve based on the official certification.
