IK Sirius vs. IF Brommapojkarna - Exact Score

Platform comparison

Market context

IK Sirius and IF Brommapojkarna meet in the Swedish Allsvenskan on 10 August 2026, with settlement tied to the exact final score after 90 minutes plus stoppage time. The Polymarket contract currently shows 0% implied probability across all listed outcomes, a pricing anomaly that typically reflects either minimal liquidity, a technical settlement issue, or genuine uncertainty about whether the match will occur as scheduled. On-chain, this resolves via conditional tokens on Polygon; traders holding YES positions on a specific scoreline (say, 2–1 to Sirius) would receive USDC only if that exact result materialises, with all other outcomes routing to "Any Other Score."

Historical Allsvenskan meetings between these sides provide limited predictive power given squad turnover and the two-year gap to August 2026. However, recent seasons show Sirius averaging 1.4 goals per match whilst Brommapojkarna typically concede 1.2 per game, suggesting scorelines clustering around 1–0 or 1–1 outcomes. The 0% reading across all explicit outcomes likely indicates that traders expect the "Any Other Score" catch-all to dominate settlement, a rational position given the rarity of exact-score prediction in football.

Traders should monitor team news and injury bulletins as the fixture approaches, particularly any late squad announcements that shift attacking or defensive capability. Fixture confirmation and any weather alerts affecting the pitch will be published via the Swedish Football Association's official channels. The settlement window closes at 17:00 UTC on match day; any postponement extends the market's life without closing it, so liquidity may remain thin until final team sheets are released.

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.
