Recent polling averages and nonpartisan forecaster updates show the four races—Georgia’s defense by Jon Ossoff, Michigan’s open seat, North Carolina’s open Republican-held contest, and Maine’s challenge to Susan Collins—remain tightly balanced toss-ups or leans, producing near-even trader consensus on a Democratic sweep. Candidate recruitment, fundraising edges, and primary outcomes have kept each contest competitive, while an expanding battlefield in states such as Alaska, Ohio, Iowa, and Texas has given Democrats additional paths but also exposed vulnerabilities in swing-state turnout and messaging. Scheduled fall debates, economic indicators, and national approval trends could shift individual margins enough to alter the joint probability before November.

A candidate will 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 nominee (e.g., Greens, Libertarian, independent) will not count. Candidates who run as independents will not be considered a Democrat, 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 all relevant races for the same candidate. If all three sources don’t call a relevant race for the same candidate, this market will use the official certification of the election results for resolution.
