Sport Boys Association vs. Club Alianza Lima

Platform comparison

Market context

Sport Boys Association host Club Alianza Lima in a Peru Liga 1 match scheduled for 8 August 2026, with the market resolving on whether Alianza Lima win within the first 45 minutes plus stoppage time. The crowd-implied 0% YES price is far below the broader betting picture, where Alianza Lima are the clear match favourite and first-half lines are still materially shorter than a true longshot implies.[1][3][5]

For a power-user reading this programmeatically, the useful comparison is not the outright result but the first-half dependency chain: if your feed ingests team news, any confirmed rotation, late injuries, or a change in starting goalkeeper/defence can move early-goal expectations faster than full-time prices. Historical pricing around this fixture has generally treated Alianza Lima as the stronger side, with bookmaker snapshots commonly showing them around 1.9-2.0 for the win and Sport Boys closer to 3.4-4.4, while head-to-head goal patterns have often clustered around low-to-mid totals rather than high-scoring blow-outs.[2][3][6][7][8]

The catalysts to watch are the line-up release, venue and kick-off confirmation, and any schedule congestion affecting Alianza Lima’s selection. ESPN’s odds board still shows Alianza with the shorter first-half moneyline and Sport Boys as the outsider, which matters because a market like this is best handled through conditional orders keyed to confirmed XI data and any late move in first-half under/over pricing.[1] Soffascore, Flashscore and similar live feeds also become relevant once the match starts, because an early tempo shift or red card can invalidate pre-match assumptions quickly.[4][16][19]

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.
