Mjallby AIF vs. IK Sirius - More Markets

Platform comparison

Market context

Mjallby AIF travel to face IK Sirius in the Swedish Allsvenskan on 15 August, with the market currently pricing the outcome at 0% implied probability for the "more markets" category—a settlement condition tied to whether additional betting options materialise for this fixture. The 0% reading suggests the crowd expects no supplementary markets to be offered, or that the question itself may be redundant given standard market provision.

Allsvenskan fixtures typically generate multiple derivative markets (goal-scorer odds, corner counts, card totals) as standard practice, particularly for mid-table matchups. Historical precedent shows that even lower-profile Swedish league games attract secondary market creation from major operators, especially when settlement windows extend to match day. The 0% probability here appears to reflect either a technical interpretation issue—where "more markets" refers to an exceptional or unusual expansion beyond baseline offerings—or genuine uncertainty about whether this particular fixture will receive coverage beyond the primary win-draw-loss market.

Traders should monitor operator announcements in the week preceding 15 August, as Allsvenskan scheduling and broadcaster commitments often trigger market expansion decisions. Mjallby's recent form and injury status, along with Sirius's league position, may influence whether bookmakers deem the match sufficiently liquid to warrant extended markets. The settlement deadline of 13:00 UTC on match day leaves minimal window for late-stage market additions, making early-week operator communications the key catalyst for reassessing the current consensus.

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.

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's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

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%.
