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

Platform comparison

Market context

Benfica meet FC St. Gallen with the market still pricing the exact score at **0% YES**, which is broadly consistent with how hard it is to land on a single correct scoreline in a knockout tie. Sportsbook pricing points the same way: Benfica were listed around **-800 on the moneyline** with a **-2.5** handicap and a **3.5** total, implying a strong Benfica edge but not a narrow consensus on one precise final score.[2] The first leg finished **St. Gallen 2-1 Benfica**, so the contract’s value now depends on whether Benfica produce a specific comeback script rather than simply winning the match.[5][10]

For historical framing, both sides have recently been involved in scorelines that cluster around **2-1, 2-2 and 3-1**, not around one dominant exact outcome. Benfica’s recent run featured wins over Sporting, Moreirense and Estoril plus draws with Braga and Famalicão, while St. Gallen’s form included wins over Basel and Lugano and a draw with Thun.[1][7] Stat models also lean towards goals rather than a tight, low-event game: one preview set Benfica’s recent scoring rate at **2.05 per game** and St. Gallen’s at **1.85**, which is consistent with the broader sportsbook total rather than any single score landing cleanly.[1]

The main catalysts are team news, rotation and whether the match is played as a chase for Benfica or a containment job for St. Gallen. Because the market settles only on **90 minutes plus stoppage time**, any late tactical shift, red card, or unexpected change in line-up matters more for exact-score pricing than for a simple win/lose bet.[3][5] Traders should also watch whether any pre-match reports move the total or handicap away from the current broad Benfica-favoured shape, as that would be the clearest cross-platform signal that the crowd’s 0% exact-score view is under- or over-stating the chance of an outlier result.[2][3]

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi vs Polymarket trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
