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

Platform comparison

Market context

Polymarket prices this Benfica–St. Gallen exact-score contract at **0% YES**, which means the current on-chain market is treating every listed scoreline as effectively unreachable on USDC-settled Polygon conditional tokens. The contract resolves on the final score after 90 minutes plus stoppage time only, so traders are underwriting a regulation-time result rather than extra time or penalties.

That flat pricing is easier to read in the context of the first leg, which St. Gallen won 2-1 in Switzerland on 23 July, giving the tie a live aggregate edge and making the return match more sensitive to game state than to pre-match theory[12]. Benfica’s domestic and European form going into the tie was still strong overall, with multiple recent wins and a high-scoring profile, while St. Gallen also came in on a run that included several wins and draws rather than a single outlier result[2][9]. Head-to-head history is thin: UEFA’s record shows just one previous meeting before this tie, a 2-1 St. Gallen win[7].

For traders, the practical catalysts are squad news, starting line-ups, and whether Benfica push aggressively from kick-off or manage the tie conservatively after the away defeat. Any late injury, rotation, or tactical shift can matter more here than in a normal league fixture because exact-score markets are very sensitive to one early goal, and the settlement window will close once the scheduled match result is final on regulation time. Live match updates were being tracked by major sports outlets around kickoff, which is the sort of feed that typically matters most for exact-score repricing[1][8].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

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.
