Mjallby AIF vs. IK Sirius - More Markets

Platform comparison

Market context

Mjallby AIF will face IK Sirius in the Swedish Allsvenskan on 15 August 2026, with kick-off scheduled for 09:00 ET. This market invites traders to purchase YES or NO shares on an unspecified proposition related to the fixture—a structure common in prediction markets where additional match-specific markets (goals, cards, player performance, or team outcomes) are bundled under a single umbrella. A YES share pays out if the condition is met; a NO share pays out if it is not. The 0% crowd probability suggests either that traders have not yet engaged with this particular market cluster, or that the underlying proposition is deemed extremely unlikely to occur.

Allsvenskan fixtures typically generate trading activity only once match details and team news solidify. Mjallby AIF finished the 2025 season in mid-table, whilst Sirius has historically occupied a competitive position in the division. Without access to the specific proposition text, traders should monitor official Allsvenskan announcements and team injury reports in the weeks preceding 15 August. Swedish football media outlets including Fotbollskanalen and Aftonbladet regularly publish squad updates and tactical previews that influence market sentiment.

The settlement window closes at 13:00 UTC on match day, leaving a narrow window for late-breaking information. Traders new to prediction markets should note that 0% probabilities often reflect incomplete information rather than certainty; as the fixture approaches and the proposition becomes clearer, probability distributions typically shift based on team form, availability, and historical precedent.

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 Prediction Market UK, which mirrors the Polymarket order book directly.

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.

UK Frequently Asked Questions

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 does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

Is Polymarket legal in the UK?

Polymarket is accessible to UK traders but is not UKGC-licensed. It operates under US CFTC jurisdiction. UK residents face no domestic legal prohibition on using it, but UKGC consumer protections do not apply. For UKGC-regulated alternatives, Betfair Exchange and Smarkets offer similar prediction-style markets.

Do I pay tax on prediction market profits in the UK?

UKGC-licensed platform profits (Betfair, Smarkets) are typically tax-free gambling winnings for UK individuals. Polymarket profits involve USDC crypto transactions, which HMRC treats as Capital Gains Tax events. Keep full transaction records and report via Self Assessment if gains exceed £3,000 per tax year.

How do I deposit on Polymarket from the UK?

UK traders typically fund Polymarket via Coinbase UK, Kraken or Revolut — buying USDC with GBP and transferring to a Polygon-compatible wallet (MetaMask, Coinbase Wallet). Polymarket's onboarding walks you through the bridging process. Typical GBP-to-USDC conversion costs 0.5–1%.
