Mjallby AIF vs. IF Elfsborg

Platform comparison

Market context

Polymarket is pricing this Mjällby AIF v IF Elfsborg contract at **0% YES**, so the on-chain market on Polygon is effectively saying there is no live conviction that the event will settle true under the contract’s terms, even though the underlying Allsvenskan fixture is scheduled for Strandvallen in Hällevik and listed for 15:30 UTC.[3][10][14] For a user holding conditional tokens bought in USDC, that means the position is being treated as worthless unless the settlement source and wording line up in a way that still allows a YES outcome.

The broader football context does not support a one-sided read on the actual match. Recent previews describe the game as tight and low-scoring, with one model even giving Mjällby, the draw and Elfsborg a near-even split, while historical head-to-head data shows a fairly balanced record overall and several recent meetings ending level.[1][13][16] That sort of parity usually matters on Polymarket because the market can swing sharply on small information edges, but a 0% price is far beyond what the team news alone would justify.

For traders, the main catalysts are the final line-ups, any late injury or suspension updates, and whether the listed kick-off and settlement details remain aligned with the match being played as scheduled.[8][14][20] The key practical risk is mechanical rather than purely sporting: on Polymarket, the outcome depends on the contract’s exact resolution criteria, so users should check the event source, final referee confirmation, and any rescheduling or abandoned-match notices before the settlement window closes.

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.
