This market will resolve according to the winner of the 2026 midterm Arkansas 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.Trader consensus in the Arkansas Senate race strongly favors incumbent Republican Tom Cotton, driven by the state's long-standing Republican lean in federal contests and his established record since 2015. Arkansas has not elected a Democratic senator in decades, creating a durable base-rate advantage reinforced by recent primary results, fundraising reports, and polling trends ahead of the 2026 general election. Democratic nominee Hallie Shoffner faces structural headwinds typical for challengers in this environment. While the market assigns low probability to an upset, scenarios that could still shift outcomes include major national political realignments, late-breaking candidate-specific developments, or unusually strong Democratic mobilization in urban and suburban pockets.
