Pronóstico: IF Brommapojkarna vs. IK Sirius

Platform comparison

Market context

The upcoming Allsvenskan clash between IF Brommapojkarna and IK Sirius at Grimsta IP in Stockholm is scheduled to kick off at 14:30 UTC on Sunday, 12 July 2026[1][4]. On Polymarket, this specific contract is priced at 0% YES today, implying the crowd believes the settlement condition will not be met before the window closes at 14:30 UTC[1]. The trade executes on Polygon using USDC, where conditional tokens represent the binary outcome of the event rather than the abstract match result itself.

Historically, head-to-head records between these sides show IK Sirius holding a significant advantage, having won 12 of the 23 matches played since 2007 compared to Brommapojkarna’s seven wins[5]. FcTables data further confirms Sirius won 12 direct matches while Brommapojkarna won only five, with four draws, suggesting a pattern where Sirius frequently dominates this fixture[8]. This long-term disparity frames the current 0% probability as a reflection of Sirius’s historical superiority rather than a random market anomaly, aligning with betting models that assign a 34.46% chance to a draw but lower odds to a Brommapojkarna victory[10].

Traders should monitor the official lineups released shortly before kick-off and any in-game injury reports, as these are the primary catalysts that could shift conditional token values if the settlement condition depends on specific player performance or match events[2]. While no specific pre-match news announcements are currently flagged in recent coverage, the live score feed on ESPN and SofaScore will provide real-time updates on goals and substitutions that directly impact the on-chain settlement[1][2]. The dependency remains strictly on the match outcome occurring within the defined settlement window, with no external schedule changes expected for this Allsvenskan round.

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

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.

FAQ

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.

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 Polymarket Qué Es 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.
