IK Sirius vs. IF Brommapojkarna - Exact Score

Platform comparison

Market context

IK Sirius and IF Brommapojkarna meet in Allsvenskan on 10 August 2026, with settlement contingent on the 90-minute result. The Polymarket contract currently prices all explicit scorelines at zero, reflecting either sparse liquidity or genuine uncertainty about which exact outcome will materialise. On-chain, traders are holding conditional tokens on USDC via Polygon, with the market remaining open through the scheduled 17:00 UTC close window. Any final score not listed among the preset outcomes triggers resolution to "Any Other Score," a catch-all that typically captures 15–25% of football matches depending on the league's typical goal distribution.

Historical Allsvenskan seasons show Sirius and Brommapojkarna occupy mid-table territory, with average goals-per-match ranging between 2.4 and 2.8 across recent campaigns. Matches between these clubs have produced scorelines clustering around 1–1, 2–1, and 2–0 outcomes, though the zero-probability reading on all listed options suggests the market may be illiquid rather than reflecting genuine predictive consensus. Comparable Allsvenskan fixtures in August typically see slightly elevated scoring as teams settle into the season's rhythm.

Traders should monitor team news and injury updates through early August, particularly any late squad changes announced within 48 hours of kickoff. Fixture congestion—whether either side faces European qualification or domestic cup commitments—can affect rotation decisions. Weather conditions in Stockholm on match day may influence play style; recent Allsvenskan reporting has flagged variable summer conditions affecting ball control and defensive organisation.

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.
