With ballots mailed on April 29 ahead of the May 19 Oregon Republican US Senate primary, trader consensus favors state Sen. David Brock Smith at 50.9% implied probability over Jo Rae Perkins at 38.5%, reflecting his surge from recent endorsements positioning him as the strongest general election challenger to incumbent Democrat Jeff Merkley. Willamette Week named Smith Republicans' best bet, citing his cross-aisle work on rural issues like wildfire prevention and estate tax relief for farming properties, while the Oregon Taxpayers Association and top GOP gubernatorial candidates also backed him in the past week. Perkins holds strong name recognition from her 2020 Senate run, but Smith's establishment support has narrowed the field of nine candidates, with others below 4%, in this closely contested nomination race amid limited public polling.

If no 2026 Oregon Republican 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 Oregon Republican Party, however an overwhelming consensus of credible reporting may suffice.
