Democratic Senate incumbents running for re-election in 2026 have secured their party nominations without defeat through early September, with figures such as Edward Markey in Massachusetts and Mark Warner in Virginia prevailing in contested primaries by wide margins. Most others, including Cory Booker in New Jersey and Jack Reed in Rhode Island, face only minor opposition or none at all ahead of remaining votes in Delaware. This pattern reflects limited primary challenges, strong fundraising by sitting senators, and party unity in safe Democratic states. Trader consensus for zero losses rests on these outcomes and historical rarity of incumbent upsets. A late upset in an ongoing primary or unexpected withdrawal could still shift the count, though current filing and polling data show no such threat materializing.

This market will resolve according to the number of Democratic Senate incumbents who do not win their nominating election to move on to the general election as a result of the 2026 midterm primary elections.
An incumbent will be considered not to have won their election if they are not declared the winner of the election they sought, including if they withdraw, suspend, or otherwise leave the race at any point after officially registering as a candidate, regardless of the reason. Incumbents who do not officially register as candidates for reelection will not be considered.
This market will resolve based on the results of all Senate nominating elections, including party primaries, top-two or jungle primaries, and primaries for special elections, that are scheduled to occur between March 1 and September 30, 2026. If a required runoff for any such election or a subsequent qualifying round in a non-partisan primary system could change the market’s outcome, the market will remain open until that contest is conclusively called by this market’s resolution sources.
A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time of their nominating election. A candidate without a ballot-listed affiliation to either the Democratic or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus prior to the conclusion of the relevant nominating election.
The resolution source for this market will be the Associated Press, Fox News, and NBC. This market will resolve once all three sources have conclusively called all relevant nominating elections. If all three sources do not achieve consensus in calling the relevant races for this market, it will resolve based on official state certification of the nominating election results.
