IK Sirius vs. IF Brommapojkarna - More Markets

Platform comparison

Market context

IK Sirius play IF Brommapojkarna in Allsvenskan, with the “more markets” contract settling on whether the match generates additional listed trading opportunities by the deadline. The crowd is at **52% YES**, which is close to a coin flip and broadly consistent with a live football event where market depth often depends on how many derivative lines appear before kick-off. Public price guides for the same fixture lean towards Sirius as favourites, with home-win odds around 1.30-1.35 and away prices in the 8.00-10.00 range, so a 52% read on “more markets” is not a match-result view but a liquidity-and-product-availability view. [2][6][16]

For a power-user, the right way to read this is as a workflow problem: monitor the event feed, then map any new derivatives against the settlement rule before the window closes. Comparable pre-match markets in football are usually driven by the release of line-ups, injury confirmations, and late pricing changes, because those are the points when books and exchange-style venues tend to add or reprice secondary markets such as totals, handicaps, player props, or first-half variants. Recent listings already show a wide menu for this fixture, including both-teams-to-score, Asian handicap, corners, and half-time lines, which suggests the market is sensitive to whether traders can source and display additional sub-markets in time. [6][7][17]

Programmatically, this is the sort of market a bot would treat as a schedule-triggered polling task: watch the match page for new selections, compare timestamps against the settlement window ending at 17:00 UTC, and only mark YES if qualifying markets are actually introduced before expiry. With kickoff listed for 19:00 local time in Sweden and the match already priced across several books, the main catalysts are not team strength alone but whether pre-match line creation, line-up publication, or broadcaster-led data updates push extra markets live before settlement.

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

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
