Incumbent Republican Michael Guest secured re-election to represent Mississippi’s 3rd Congressional District on November 3, 2026, with preliminary results showing him receiving approximately 58 percent of the vote against Democratic challenger Michael Chiaradio’s 40 percent and a Libertarian candidate’s remainder. Guest, first elected in 2018, maintained strong backing in this solidly Republican district through consistent emphasis on border security, tax policy, and alignment with state priorities. Chiaradio, a first-time candidate and regenerative farmer, focused on healthcare access, infrastructure, and agricultural support but trailed significantly in fundraising and faced structural headwinds typical of the district’s voting patterns. Trader consensus at near-certainty for Guest reflects these confirmed tallies, though full certification or any recount proceedings could still influence final market resolution.
