Sport Boys Association vs. Club Alianza Lima

Platform comparison

Market context

Sport Boys Association’s meeting with Club Alianza Lima in Peru Liga 1 is priced by the crowd at a near-certain Alianza outcome, and that lines up with the historical record. Across major head-to-head databases, Alianza have won far more often than Sport Boys, with recent meetings also leaning their way: one 3-1 win in October 2025, a 1-0 away win in May 2025, and earlier 3-0 and 3-1 victories in 2024-25.[5][13][14]

For traders, the main catalyst is still the same: line-up news and any late team-sheets closer to kick-off, rather than anything resembling a “poll move”. There are no campaign-style declarations or disclosure dates in play here, so the market is effectively leaning on football scheduling and availability signals. Aggregators such as Flashscore, Sofascore and 365Scores all list the fixture for 9 August 2026, but they do not yet provide the decisive squad information that would justify a late repricing.[15][17][18]

What matters most is whether Alianza travel with a full-strength side and whether Sport Boys can disrupt the familiar pattern of one-sided results. The broader H2H sample is heavily tilted towards Alianza — for example, one dataset shows 23 Alianza wins to 9 for Sport Boys in 40 meetings — so absent an unexpected team-news shock, the current 0% YES price is anchored to that long-run mismatch rather than any short-term swing.[1][9][16]

Methodology

Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for Sport Boys Association vs. Club Alianza Lima plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.

Resolution & payout

Political markets typically settle on official candidate or agency confirmation. Polymarket uses UMA Optimistic Oracle: a proposer posts the outcome with a bond, the two-hour window opens, then the smart contract pays USDC.

Kalshi settles USD via CFTC clearinghouse, with clearly defined resolution sources (e.g. AP race calls for elections). Betfair settles after the official outcome is registered with the league or agency. Manifold is play-money.

UK Frequently Asked Questions

How accurate are political prediction markets?

Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.

Can prediction markets influence election outcomes?

Markets reflect expectations rather than create them. Studies show public-facing markets can anchor expectations, but don't influence the underlying outcome. Political markets are information, not advocacy.

Which platform has the deepest political liquidity?

Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.

How fast do political markets react to news?

High-liquidity markets move within seconds to minutes. A Trump tweet on the economy can shift the "Trump 2024" market 2-5 points before mainstream media has written anything.

Are UK election prediction markets available from the UK?

Yes. Betfair Exchange and Smarkets offer UKGC-regulated UK election markets (seat counts, party share, constituency results). Polymarket also lists UK election contracts with deeper global liquidity. Betfair winnings are typically tax-free for UK individuals; Polymarket profits are subject to HMRC CGT.
