Jeju SK FC vs. Gangwon FC

Platform comparison

Market context

Jeju SK FC faces Gangwon FC in a K-League match scheduled for Tuesday, 21 July 2026, with the crowd assigning a 23% implied probability to a specific outcome. Historically, this fixture favours Gangwon; in 32 prior meetings, Gangwon won 13 times while Jeju secured only six victories, with 13 matches ending in a draw[1]. Gangwon also holds a goal advantage, scoring 52 compared to Jeju’s 40 across these encounters[1]. For a power-user building a copy-trading bot, this historical skew suggests the current 23% probability may be undervalued if the market is pricing in a Jeju win, or conversely, correctly priced if the bet targets a draw or Gangwon victory depending on the specific contract definition.

Programmatic traders should monitor pre-match squad announcements and weather dependencies, as K-League outcomes often hinge on late lineup changes or pitch conditions. A recent analysis of Gangwon’s away form highlights their reliance on defensive stability, which could be disrupted by fatigue or injury news released within the next few hours[1]. When setting conditional orders, users must account for the settlement window ending at 10:30 UTC on 21 July, ensuring execution logic triggers before the match concludes. Tracking official club feeds for manager comments on player fitness provides the most reliable catalyst for adjusting algorithmic positions before liquidity shifts.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
