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 tied to the 90-minute regulation result. The market currently shows zero liquidity at any price point, typical for fixtures more than a year out where conditional token depth remains sparse on Polygon. USDC-denominated outcomes here trade against the "Any Other Score" catch-all, meaning traders are pricing not just the likelihood of a specific scoreline but the relative scarcity of that exact result versus all alternatives combined.

Exact-score markets in Swedish football have historically clustered around 1–1 and 1–0 outcomes, which account for roughly 35–40% of Allsvenskan matches collectively. Sirius finished mid-table in recent seasons whilst Brommapojkarna has oscillated between promotion-chase and mid-tier finishes. Head-to-head records show competitive, often low-scoring encounters; draws feature prominently. The 0% probability reflected here signals either no active traders pricing this contract yet or a technical settlement condition traders view as sufficiently ambiguous to avoid entry until closer to match day.

Traders monitoring this fixture should track both clubs' summer transfer activity and injury lists as August approaches, particularly any departures of key attacking players. Fixture congestion in late July—typical for Allsvenskan scheduling—can affect squad rotation and fatigue levels by 10 August. Official team news usually emerges 48–72 hours before kickoff; conditional token positions typically consolidate once lineups are confirmed and weather conditions for Stockholm are known.

UK Frequently Asked Questions

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

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.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
