The June 2 Republican primary produced a runoff between businessman Toby Doeden and incumbent Governor Larry Rhoden after neither reached the 35% threshold needed to win outright, with Doeden at 31% and Rhoden at 25% amid record GOP turnout exceeding 34%. U.S. Rep. Dusty Johnson and House Speaker Jon Hansen fell short and were eliminated. Pre-primary polling showed a fragmented field with Johnson often ahead, yet Doeden outperformed expectations through strong rural and eastern South Dakota support while Rhoden benefited from incumbency and name recognition following his 2025 elevation from lieutenant governor. The July 28 runoff remains closely contested as both candidates consolidate their coalitions ahead of the general election.

The resolution source for this market will be the first official announcement of the results from the South Dakota Republican Party; however, an overwhelming consensus of credible reporting may suffice.
