David Roth leads Idaho's Democratic U.S. Senate primary market at 75% implied probability as the 2022 Democratic nominee, giving him superior name recognition and established campaign infrastructure among the state's limited Democratic primary voters ahead of the May 19 contest. His prior statewide run, active website, and FEC filings since 2023 signal stronger organization compared to challengers Brad Moore (13.5%), a Boise resident with a recent campaign launch, and Nickolas Bonds (4.2%), an estate executive with minimal prior visibility. No public polling exists for this low-turnout race, but trader consensus reflects Roth's incumbency-like edge in deep-red Idaho, solidified after the April 8 filing deadline confirmed these as the primary field with no major disruptions since.

If no 2026 Idaho Democratic Senate Primary takes place, this market will resolve to "Other".
The resolution source for this market will be the first announcement of the results from the Idaho Democratic party, however an overwhelming consensus of credible reporting may suffice.
