- Will Democrats win all "core four" senate races?55¢55%
The market's near-even odds reflect tight polling averages in Maine and Michigan, where Democratic challengers Troy Jackson and Abdul El-Sayed hold slim leads over Republican incumbents Susan Collins and Mike Rogers, balanced against clearer Democratic advantages for Jon Ossoff in Georgia and Roy Cooper in North Carolina. Recent surveys show these four races remain sensitive to turnout among swing voters, economic concerns, and candidate-specific dynamics in the final week before the November 3 election. Strong Democratic performance in the two toss-ups would secure all four wins, while any slippage in Maine or Michigan could prevent a sweep despite favorable positioning elsewhere. Fundraising edges, advertising volume, and voter enthusiasm in these battlegrounds continue to shape trader assessments of the outcome.
Rules
This market will resolve to “Yes” if a candidate representing the Democratic Party wins the 2026 midterm U.S. Senate elections in Georgia, Michigan, North Carolina, and Maine (inclusive of any run-offs). 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.
