This market will resolve according to the winner of the 2026 midterm Kansas 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 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.Incumbent Republican Sen. Roger Marshall secured his party's nomination in the August 4 primary with nearly 80% of the vote and now faces Democratic nominee Adam Hamilton, a pastor who prevailed in a crowded Democratic primary. Kansas has not elected a Democrat to the U.S. Senate since 1932, and nonpartisan ratings classify the race as likely or safe Republican. Recent polling shows Marshall ahead by roughly four points among likely voters, consistent with the state's longstanding Republican tilt in federal contests and the advantages of incumbency. These factors underpin the current trader consensus favoring a Republican victory on November 3, with limited indications of a competitive shift in the final weeks.
