Market context
Hammarby IF secured a decisive 4–0 victory over Degerfors IF in their Allsvenskan fixture on 19 July 2026, confirming the outcome that the prediction market “Hammarby IF vs. Degerfors IF – More Markets” had priced at 100% YES [1]. The match, played at 10:30 AM ET, saw Hammarby dominate with four goals and no reply, aligning precisely with the crowd-implied certainty before settlement.
Historically, when Allsvenskan markets reach 100% implied probability on a specific outcome, settlement has almost invariably followed the pre-match consensus, particularly in matches involving top-half teams like Hammarby against lower-ranked opponents such as Degerfors. Comparable cases from the 2024 and 2025 Allsvenskan seasons show that odds converging to decimal 1.00 (or 100% probability) on platforms like Betfair and Smarkets typically reflect near-certain results, with minimal variance post-match [2].
Traders comparing Polymarket, Kalshi, Betfair, and Smarkets should note key divergences: Polymarket and Kalshi display outcomes as binary YES/NO probabilities with no-KYC access (Polymarket) or full KYC (Kalshi), while Betfair and Smarkets use decimal odds and require identity verification for larger stakes. Fee structures also differ—Polymarket charges no trading fees but has network gas costs, whereas Betfair applies a commission on winnings and Smarkets offers low, transparent fees. On this settled market, all platforms would have resolved YES, but only Polymarket and Kalshi would have allowed anonymous entry at the 100% price point.
