Market context
The race has narrowed to a straight two-way contest between **Peggy Flanagan** and **Angie Craig**, with the primary set for 11 August and no major late-breaking entry changing the field in the last 24–48 hours.[1][2][3] The current crowd-implied **71%** likely reflects that the contest is already well defined, even if recent reporting still describes it as competitive and costly rather than settled.[5][13]
Historically, Minnesota Senate primaries have tended to reward the candidate who can combine strong party support with a clear electability case, especially in open-seat races where endorsements and money shape early perceptions.[1][8][9] That framing matters here because Craig has led in fundraising and some establishment support, while Flanagan has held the advantage in endorsement-heavy and polling snapshots, including a recent survey showing her ahead 43% to 36%.[1][7][10][16] In that sense, 71% is consistent with a race that looks favourably positioned for one side, but not remotely locked.
Traders should watch for any final-turnout cues from the Minnesota DFL, last-minute endorsement consolidation, and whether the campaign debate remains focused on electability versus ideological contrast.[1][5][9][13] The key dependency is simple: the market resolves from the first official result announcement by the state party, with overwhelming consensus reporting serving as a backstop if needed.[1] If primary-day turnout is uneven, or if late absentee and urban vote swings break harder than expected, the implied probability can move quickly in either direction.
Methodology
This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Today, which mirrors the Polymarket order book directly.
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.
UK Frequently Asked Questions
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- 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%.
