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 the match kicking off at 13:00 ET. The market requires selection of an exact final score from a predefined list; any outcome not explicitly listed resolves to "Any Other Score." Settlement occurs at 17:00 ET on match day, accounting for 90 minutes of regulation plus stoppage time only. The 0% crowd probability suggests either no explicit outcome has yet attracted backing, or the listed options fail to capture expected scorelines given recent form.

Exact-score markets in Allsvenskan typically see probability mass concentrated on low-scoring results (1–0, 1–1, 2–1) reflecting the league's defensive structure and mid-season fixture congestion. Historical data from comparable Swedish top-flight encounters shows that when one side enters as clear favourite, the modal outcome remains a single-goal margin rather than heavy scorelines. Traders should cross-reference recent head-to-head records: Sirius and Brommapojkarna's last five meetings establish baseline volatility and whether either club systematically underperforms or overperforms expected goal differentials.

Programmatic traders should monitor team news releases for injury confirmations and lineup changes through 9 August, as absences of key attacking or defensive players shift expected score distributions measurably. Weather forecasts for Stockholm on match day merit inclusion in conditional-order logic, given wind and rain historically compress scoring in Allsvenskan fixtures. Fixture scheduling—whether either side plays a midweek cup match beforehand—affects fatigue profiles and should feed into model adjustments before settlement.

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.

FAQ

Where can I trade this market with the lowest fees?

Polymarket is geo-blocked in the US/UK/EU. The easiest 0%-fee broker into the same order book is Kalshi Fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
