IK Sirius vs. IF Brommapojkarna - More Markets

Platform comparison

Market context

IK Sirius play IF Brommapojkarna in an Allsvenskan fixture, and the “more markets” market is really a question about how much extra in-play and prop coverage the sportsbook/marketplace will expose around that match. With the crowd at **52% YES**, the market is close to a coin flip: it slightly favours additional derivatives being listed, but not by enough to imply certainty. For a programmatic trader, that usually means treating the market as *schedule- and liquidity-sensitive* rather than a pure view on the match itself.

Comparable pricing across football books points to a match expected to generate plenty of marketable action, which matters because more markets are often added when there is a clear pre-match favourite and enough statistical texture to price side markets. Sirius are strong favourites across the board, with one bookmaker showing them at 1.32 and the away side at 8.50, while another set of odds implies Sirius win probability in the high-70s and both teams to score around the mid-60s to high-50s range.[8][10][7][14] That kind of profile tends to support derivative menus such as BTTS, totals, corners, first goalscorer and half-time lines, which is the sort of surface a bot or conditional-order workflow can monitor for new listings and repricing.[7][18]

The key catalysts are straightforward: official line-ups, any late injury or rotation news, and whether the pre-match market depth justifies extra props before kick-off. Sofascore and Flashscore both have the fixture indexed for 10 August, while odds boards already show active 1X2 and totals pricing, suggesting the underlying game is live enough for bookmakers to extend the menu if their automation thresholds are met.[1][17][7] If you are scripting around it, the practical checks are whether the book posts additional team, player or period markets as line-ups land, and whether the market is still open long enough before the 17:00 UTC settlement window to count newly created listings as “more markets”.

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.

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.
