Market context
The Minnesota Republican primary for governor is now the final test of a crowded field that has already produced mixed signals: state House Speaker Lisa Demuth won the party’s straw poll with about 31.9%, while party-endorsed Kendall Qualls, Mike Lindell and Scott Jensen each retained enough support to keep the race open.[1][3] That split matters because the market’s 62% implied Yes price sits closer to a favourite than a toss-up, but not so high that it assumes a settled field; in comparable multi-candidate primaries, a convention endorsement or a strong early poll can be overtaken quickly if the vote fractures along establishment-versus-outsider lines.[2][3][4]
For traders, the immediate catalysts are simple: any late campaign statements, turnout signals from early voting, and the first official result from the Minnesota Republican Party on 11 August.[4][7][11] Recent polling has not been stable, with one SurveyUSA poll for KSTP showing Lindell ahead 34% to 28% over Demuth, while other coverage has described Demuth, Qualls and Lindell as the main contenders and noted that Trump’s endorsement remains a live variable.[2][4][6] If the race goes to a second round or run-off, the settlement only turns on the eventual overall winner, so delegates, endorsements and late consolidation will matter as much as the initial ballot share.[2][11]

UK Frequently Asked Questions
- Are prediction markets better than sports betting?
- Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.
- Can I bet on individual matches?
- Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.
- Is Polymarket legal in the UK?
- Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.
- Do I pay tax on prediction market profits in the UK?
- UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.
- How do I deposit on Polymarket from the UK?
- UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
