Will Democrats win all "core four" senate races?

Resolution 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.

FAQ

How are prediction market odds calculated?

Each contract pays $1 if the outcome happens and $0 if it doesn't, so its price is the market's implied probability: a 60¢ contract means roughly a 60% chance. We show the last trade, or the midpoint between the best bid and ask when the order book is tight.

When does this market close?

Polymarket lists Nov 4, 2026 as the end date; this market has closed.
