Market context
Al Nassr will face Al Fateh in the Saudi Professional League on 15 August, with the fixture scheduled for 2:00 PM ET. The market's 100% implied probability reflects near-certainty that additional betting markets will be offered for this match, though the settlement window closes at 6:00 PM ET the same day—leaving only four hours post-kickoff for resolution. This timing constraint is the primary driver of the extreme probability, as sportsbooks typically launch supplementary markets (goal scorers, corner counts, card totals) well before or immediately after matches commence.
Historical precedent suggests Saudi Professional League fixtures routinely attract expanded market offerings from major operators. Nassr, as the league's most commercially prominent club and recent title contenders, typically generates sufficient trading volume to justify multiple market tiers. Al Fateh, whilst a smaller franchise, competes in the same tier and has featured in comparable multi-market offerings. The 100% reading therefore reflects operational convention rather than novel uncertainty about whether markets will materialise.
Traders should monitor whether either club reports late team news or injuries in the 24 hours before kickoff, as significant absences occasionally delay or restrict market expansion. Fixture confirmation and official team sheets typically arrive 48–72 hours prior; any postponement would immediately collapse this probability. The settlement window's brevity means resolution depends entirely on whether markets are live before the match concludes, making exchange availability and operator decisions the decisive factors rather than match outcome itself.
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
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
