IK Sirius vs. IF Brommapojkarna - More Markets

Platform comparison

Market context

IK Sirius host IF Brommapojkarna in an Allsvenskan match, and this **More Markets** contract is sitting near a coin flip at **52% Yes**, which is firmer than several public model lines but still short of a clear consensus. Recent sportsbook-style previews are broadly more bullish on Sirius at home: one market comparison puts Sirius at about **44.8%** to win, while another algorithmic preview gives the home side **54.1%** and a separate one prices Sirius at **1.33** with a projected **2-1** scoreline.[12][4][5]

That leaves the prediction market close to the centre of a range rather than obviously mispriced. Comparable estimates also lean towards a home edge and goals, with one source listing Sirius’ home xG advantage and strong home win rate, while others point to BTTS or over 2.5 goals as live angles; that combination usually matters for “more markets” contracts because late price action can be driven by whether the fixture context looks open or cautious.[16][18][9]

The main catalysts before settlement are team news, confirmed line-ups and any late schedule change, because those inputs can shift both the win expectation and the goal environment quickly. Match preview sources already frame Sirius as the more likely winner, but the spread between a modest home lean and a much stronger home-favourite view means traders should watch whether pre-match information confirms Sirius’ attacking edge or narrows the game into a lower-event contest.[1][8][14]

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.
