Market context
Polymarket is pricing this Scottish Premiership side market at **0% YES** right now, which on the contract means no one is currently willing to pay for the outcome despite the match being on the calendar. Because the market settles through USDC on Polygon via conditional tokens, that price is best read as a live trading signal rather than a view of the football itself.
For context, St Johnstone and Kilmarnock have a long, fairly balanced head-to-head history, but recent meetings have often swung Kilmarnock’s way: ESPN’s last five listed results show Kilmarnock winning three, including 3-1 in February 2025 and 2-1 in December 2023, while St Johnstone took two, including 1-0 in November 2024[16]. Across a broader sample, FootyStats records 19 St Johnstone wins, 14 Kilmarnock wins and 5 draws in 38 meetings, which is enough to keep the matchup familiar without making it one-sided[1]. That mix matters for traders because a 0% quote usually reflects thin liquidity, not certainty that the event cannot happen.
The main catalysts are straightforward: confirmed line-ups, late injury or suspension news, and any schedule or venue changes before the 13:00Z settlement window closes. Sky Sports’ match stats from a previous meeting showed a narrow shot count and limited separation in possession, which is the sort of profile that can leave “more markets” contracts sensitive to one tactical or personnel update[2]. If no fresh team news arrives, the market can remain pinned at zero even as the underlying fixture approaches, so traders tend to watch official club posts and matchday squads more closely than the abstract fixture listing.
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.
