Market context
FC Porto face SCU Torreense in a Portugal Super Cup fixture, and in this prediction market a **YES** share only pays out if the “More markets” condition is met by the market’s settlement rules; a **NO** share pays if it is not. With the crowd-implied probability at **0% YES**, the market is pricing that condition as effectively absent, which is a strong signal that traders see the relevant extra outcome as extremely unlikely in this setup.
To read that 0% figure, it helps to compare it with the broader match picture. Conventional betting markets made Porto overwhelming favourites, with 1X2 prices around 1.05–1.10 for a Porto win and roughly 20.00–31.80 for Torreense, depending on the bookmaker.[1][4][5] That kind of gap usually reflects a mismatch in squad quality and depth, and it also tends to reduce the chances of unusual event-driven markets landing. Similar pre-match models and previews also leaned towards Porto, with Sports Mole giving Porto a 51.6% win probability and several scoreline models clustering around low-to-mid scoring Porto wins.[17][19]
For traders, the main catalysts are late team news, confirmed line-ups, and any change to match scheduling or competition format. Porto’s official squad availability, starting XI announcements, and whether Torreense can field a full-strength side matter more here than broad season-long form because cup fixtures can turn on rotation and absences. Markets can also move if there is a weather delay, a venue change, or confirmation that the match is using a different settlement basis than expected; the listed kick-off in the sources was Saturday 1 August at 21:15 local time, equivalent to 19:15 UTC.[5]
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
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
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.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK 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.
