Granada CF vs. RCD Mallorca - More Markets

Platform comparison

Market context

Polymarket has this contract at 100% YES, which leaves no spread for traders to express uncertainty through the market price. For a user on Polygon, that means the position is being priced as a near-certain settlement rather than a live view on the football itself, with USDC backing the trade and conditional tokens determining the payout if the market resolves as expected.

The best historical comparison is not a long-shot cup tie, but a routine fixture where the market has already absorbed the event as a certainty before kick-off. Granada and Mallorca were scheduled for the LaLiga 2 meeting at Estadio Nuevo Los Cármenes on 24 August, and the club-side listings place the match at 19:30 local time, with live scores later confirming a 2-0 Granada result. That kind of pre-set pricing usually reflects timing and data confidence more than any view on goals, cards, or a specific scoreline.

For traders, the relevant catalysts are administrative rather than tactical: fixture confirmation, kick-off time, and whether the match proceeds on the published schedule before the settlement window closes. ESPN’s fixture listing and LaLiga’s match page both showed the game on 24 August, which reduces date risk, but any late schedule change, abandonment, or dispute over match status would matter more to settlement than team news.

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

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.
