Show full assessmentShow less

The rules clearly specify what determines the winner, explicitly accounting for any necessary run-offs. Party affiliation is strictly tied to official nomination, noting that independent candidates will not count toward the party options even if affiliated. Resolution relies on consensus calls from three named news organizations (Associated Press, Fox News, and NBC), with an explicit fallback to official state certification if all three do not agree on the winner. Replacement of a party nominee before election day is also clearly addressed.

Resolution rules

This market will resolve according to the winner of the 2026 midterm Mississippi 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.
