California's 3rd Congressional District held its June 2, 2026, nonpartisan primary under the state's top-two system, in which the two highest vote-getters advance to the November general election. Recent vote tallies show Republican Robb Tucker and Democratic incumbent Ami Bera leading the field, with Tucker at approximately 34 percent and Bera at 33 percent; other candidates, including additional Republicans and Democrats, trailed significantly. Redistricting under Proposition 50 altered the district's boundaries, incorporating more of northern Sacramento County and shifting its partisan leanings. The primary followed candidate filing in March and a certified ballot list released by the Secretary of State. Market pricing reflects trader assessment of these preliminary results and the low likelihood of major changes from remaining ballots or official certification.
