**Democratic traders see a slim edge in sweeping the core four races—Georgia, Michigan, North Carolina, and Maine—because individual race pricing currently favors Democrats in each, yet the joint probability remains near even at 54%.** Holding open or vulnerable Democratic seats in Georgia (Jon Ossoff) and Michigan (Gary Peters retirement, now Abdul El-Sayed vs. Mike Rogers) while flipping Republican-held seats in North Carolina (Roy Cooper favored) and Maine (Susan Collins contest) demands consistent strength across diverse electorates. Recent primary outcomes, polling margins in the single digits, and fundraising edges have kept the races tight, with national economic sentiment and candidate-specific factors able to shift any one contest enough to break the sweep. Late-cycle developments such as turnout patterns, economic data releases, or candidate-specific events within the final weeks could therefore move the combined odds noticeably in either direction.

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.
