Market context
The Minnesota Republican primary for governor is due on 11 August, with the market’s **62%** implied probability putting the current favourite clearly ahead but not in landslide territory. In handicapper terms, that leaves a meaningful underdog lane: the field has been competitive enough that a late shift in turnout or organisation could still matter, even if the consensus has narrowed towards one front-runner.[4][17]
The historical analogue is a fractured primary rather than a coronation. Ballotpedia notes a record seven-candidate field, while recent coverage has consistently grouped **Lisa Demuth, Kendall Qualls and Mike Lindell** as the main contenders.[2][4][5] Polling has not been uniform: the New York Times’ poll tracker has shown Lindell ahead in several late-July and early-August surveys, including a SurveyUSA poll at **34% to 28%** over Demuth, while an earlier caucus straw poll had Demuth first at about **31.9%** with Qualls and Lindell trailing.[3][8] That split is why the market looks playable rather than fully efficient: if the crowd is leaning on Lindell’s recent polling lead, the contrarian angle sits with Demuth or another candidate benefiting from endorsement structure and vote fragmentation.[2][12]
The key catalysts are immediate rather than distant. The election itself is on **Tuesday, 11 August**, early voting has already been available, and the resolution will turn on the first official result from the Minnesota Republican Party unless reporting reaches an overwhelming consensus.[9][17] Traders should watch for turnout signals, any late campaign statements, and whether one of the leading names converts polling into actual precinct returns; with seven tickets on the ballot, a modest misread in mobilisation could decide the winner more than headline support would suggest.[5][9]
Methodology
We track Minnesota Governor Republican Primary Winner across the five venues with material prediction-market liquidity. The probability shown is the live Polymarket mid; the comparison rows summarise how each venue treats the underlying contract — fees, KYC thresholds, settlement currency, deposit options. The highlighted row marks the cheapest route into Polymarket's order book.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
