Sport Boys Association vs. Club Alianza Lima

Platform comparison

Market context

Sport Boys Association vs Club Alianza Lima is trading at **0% YES** on Polymarket, so the market is pricing the contract as effectively dead even before kick-off on Saturday’s Peru Liga 1 fixture. On Polymarket, that means users are swapping USDC on Polygon through conditional tokens: the contract only resolves if the specified match outcome is confirmed by the market’s settlement rules, and with the window closing at 2026-08-09T01:00:00Z, the final outcome needs to be settled promptly from the official result.

The historical frame still points one way. Across recent head-to-head data, Alianza Lima has had the stronger record, with sources putting the rivalry at roughly 22-23 wins for Alianza and 9-10 for Sport Boys in 39-40 meetings, alongside 8 draws[1][4]. Recent meetings have also leaned Alianza’s way, including a 1-0 win in February 2026 and a 3-1 win in October 2025, which is the sort of sequence that usually keeps a favourite’s YES side supported rather than collapsing to zero[5][14][17]. Even so, Sport Boys have taken occasional points in this fixture, so a near-zero price is a market judgement about current event risk, not a statement that the underlying match is impossible.

The main trader catalysts are straightforward: confirmed line-ups, late injury or suspension news, and any change to the match schedule or venue before the official start. Recent fixture listings already show the match on 9 August 2026, but Polymarket resolution depends on the final, official result rather than pre-match expectations, so traders often watch the club and league announcements closely in the hours before kick-off[16]. Because the contract is resolved in the prediction-market layer, any delay, postponement, or administrative rescheduling matters as much as the football itself.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
