The "No" side holds a modest edge in this market because winning all four competitive contests simultaneously remains a high bar even with Democratic advantages in several. The core four—Georgia, Michigan, North Carolina, and Maine—feature open seats or vulnerable incumbents, with recent polling averages showing North Carolina’s Roy Cooper leading by 7–9 points while Michigan and Maine stay within single digits amid candidate shifts. In Maine, the Democratic nominee change following Graham Platner’s campaign suspension introduced fresh uncertainty into a race against Susan Collins. Georgia’s Jon Ossoff maintains a lean-D posture but faces a well-funded Republican challenge in a state Trump carried in 2024. Traders price in the historical difficulty of sweeping multiple battlegrounds in one cycle, where turnout variations, late-cycle developments, or modest Republican overperformance in any single state could prevent a clean sweep.

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.
