IK Sirius vs. IF Brommapojkarna

Platform comparison

Market context

IK Sirius host IF Brommapojkarna in an Allsvenskan match, and the market’s 73% yes price points to a fairly strong home-favourite read rather than a near-lock. Comparable pre-match models are mixed but consistently tilt towards Sirius: several previews put the home side around the mid-50s to low-80s for a straight win, while goal-based angles lean higher-scoring, with common scorelines such as 2-1, 3-1 or 1-1 appearing across forecasters[1][3][4][5][6][9][15].

For power users running this through a bot or conditional-order stack, the main inputs are team news, line-up confirmation and any late movement in the 1X2 and totals markets. Recent previews describe Sirius as the side with the stronger home profile, including an 86% home scoring rate and a positive xG margin, while Brommapojkarna are often framed as dangerous enough to score but not dominate possession or shot volume[16][18]. In practice, that means watching for striker availability, goalkeeper changes and any schedule or postponement risk before the 17:00 UTC settlement window closes; if a match is delayed, comparable market rules usually keep resolution open until the game is completed[17].

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Kalshi Fees, which mirrors the Polymarket order book directly.

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

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

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.

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.
