Sport Lisboa e Benfica vs. FC St. Gallen - Exact Score

Platform comparison

Market context

Sport Lisboa e Benfica’s second leg against FC St. Gallen is a straightforward exact-score market, but the current 0% YES price on a listed score needs to be read against the first leg, which St. Gallen won 2-1 in Switzerland on 23 July. Benfica’s recent results suggest they still create and score consistently, while St. Gallen have also been producing goals in league and cup play, which keeps “Any Other Score” structurally live even when one side is favoured to advance or dominate possession.[9][11][13]

For comparison, a 0% YES on Polymarket usually reflects the crowd assigning almost no chance to one specific scoreline, not to Benfica winning the match itself; exact-score books also price far more granular outcomes than win/draw markets. On Kalshi, the same idea is typically expressed as an implied probability, whereas Betfair and Smarkets show decimal odds and then subtract commission differently, so the same belief can look cheaper or more expensive depending on the venue’s fee structure and whether the user is fully KYC’d in that jurisdiction. In this kind of market, traders often anchor to recent head-to-head scorelines, but football’s score distribution is still wide enough that low-probability exact scores can move sharply on team news or early line-up leaks.[9][14]

The main catalysts are the confirmed starting XIs, any late injury or rotation updates, and whether the second-leg context changes Benfica’s approach after trailing from the first match. UEFA’s match listings and live match centres confirm the fixture and timing, while live data services show pre-match pricing and in-play state; if the game goes beyond 90 minutes, extra time is excluded for settlement here, so only the final score at full time matters.[3][4][7][8]
